Then how do I vote lock the commands that is what I'm trying to do
onyx summit
well, you have to listen on the vote event, then store every new vote anywhere, and then when someone is running the command you check if he is in your db
quartz kindle
^
winged thorn
don't vote
onyx summit
I can just setup the vote server for you xD
onyx summit
Then delete it
quartz kindle
onyx summit
I'm seeing that
blissful wind
If it makes you feel better I'm trash at webhooks and API's, I usually try to avoid them 
quartz kindle
neither have i, but they are not hard to understand lul
lusty dew
I haven't read up on em tbh
quartz kindle
i dont like vote locking
onyx summit
It's basically just a post request
lusty dew
I should but eh
blissful wind
JSON API's are a good learning point though. If you're a weeb, try setting up the nekos.life API or even random.bird if you're a bird lover like me
quartz kindle
yeah i have my own api as well
earnest phoenix
vote locking is nasty
earnest phoenix
ok
lusty dew
Thank you
earnest phoenix
no one is telling them to change it
onyx summit
I'm also vote locking a feature to prevent spamming lol
earnest phoenix
lol
blissful wind
Vote locking is also a good way to low-key promote voting, so I mean, why not haha
onyx summit
anyway, is level a file based db? Never used it
lusty dew
Idk
blissful wind
level?
quartz kindle
yeah leveldb is file based, but its very efficient
blissful wind
earnest phoenix
votelocking is bad in my opinion; it's turning away users from using your bot because people don't wanna bother, and it's equivalent of having to watch ads in mobile games in order to get something, except here the bot owner isn't even getting any money despite DBL putting ads on your bot page 🙃
Can I get help
Can I get help
Oops lag
quartz kindle
but level doesnt support multiple clients last time i checked, which is a no-no for sharded bots
onyx summit
Just ask what you want holy shit
quartz kindle
sqlite is a good solution for most discord bots
earnest phoenix
Yes for tickets
onyx summit
nah I'm just seeing that Haruna switched to level db
earnest phoenix
Tickety
blissful wind
I agree with Tim, SQlite, MySQL, mongoDB are all really good
onyx summit
I don't think this is the right channel
blissful wind
I prefer SQLite and MySQL
onyx summit
Not here
earnest phoenix
Where did
onyx summit
I don't give a fuck what that bot has as prefix
blissful wind
kun go to general if you wanna figure out a bot prefix, or just go into the testing channels and ask around there
onyx summit
Nothing related to developing

I'm chill

Try the support server @earnest phoenix
onyx summit
@tight heath why mmmm? PostgreSQL good 
blissful wind
jesus christ we have a troll
tight heath
@onyx summit that's the point
earnest phoenix
I GOT TO HERE
onyx summit
Yas
lusty dew
No
earnest phoenix
this isn't a support server for any bot, this is simply a bot listing service
opaque eagle
postgres good
onyx summit
STILL WRONG CHANNEL
tight heath
cry stop crying
onyx summit
THIS HAS NOTHING TO DO WITH DEVELOPMENT
tight heath
tight heath
@earnest phoenix no it isn't pls stop caps or i will eat all your pancakes
onyx summit
okay at least we all agree that psql is good
earnest phoenix
postgres is genuinely nice for big scale projects
onyx summit
No not the pancakes 
opaque eagle
@earnest phoenix Go to the bot's support server --> https://discordbots.org/bot/352854019934257156 (Click the white Join Support Server button, not the Join Discord one at the top of the page)
And ask for help there
earnest phoenix
I fucked up
opaque eagle
ye we know
blissful wind
definitely
opaque eagle
we've been trying to tell u
earnest phoenix
I said !help and now I got 100 DMs
opaque eagle
thats ur problem
blissful wind
opaque eagle
is that enough proof that we're a bot listing service and not tickety support?
onyx summit
But this is the support server 
tight heath
@opaque eagle how is Excuse defined?
onyx summit
it says right there "Discord Bot List"

That's identical to js while (true) { console.warn('reeee kill meee') }

Console is indeed slow
afaik console logging in an endless loop will fill ram very fast

@onyx summit I'ma figure this voting thing out
onyx summit
but
lusty dew
But what?
onyx summit
I wanted to clone it rn
lusty dew
Clone what
opaque eagle
Clone what
lusty dew
Sure to ahead
lusty dew
Hm?
lucid iris
Really noob question: how do you handle storage in node.js?
I don't need to persist data, I already use a DB for that. I want some runtime memory to introduce a cooldown on certain commands.
lusty dew
Okay added in the token and auth into my bot.json @onyx summit
mossy vine
just use a variable and pass it to other functions if needed @lucid iris
onyx summit
I think a Map is what you would need for cooldown
dude I said in vote-server/config.js
mossy vine
depends
onyx summit
but I will just get it out of there lol
lusty dew
Oh sorry
mossy vine
Map seems to be the best option
lusty dew
@onyx summit do you want me to change it
onyx summit
I already did
mossy vine
i use Sets and timeouts now. its a horribly inefficient method but i dont care enuogh to rewrite those 7 lines
onyx summit
yes, remove that stuff from your bot, bec port 30 001 is blocked xD
onyx summit
fixed it for you, but just saying: ' is not allowed in json
onyx summit
so basically you should be able to do
// your command stuff
if (! await client.voted.hasVoted(some user id)) console.log('that person didnt vote');
Okay thanks!
onyx summit
more info?
lusty dew
It just keeps sending the message that if they haven't voted
Won't send the embed if they already have
And I voted myself to test this

Hello
onyx summit
did you reinstall everything?
split hazel
Nope, i upgraded npm using the n package
onyx summit
then reinstall node modules
split hazel
should i just run npm install
onyx summit
you can press on "test" @lusty dew to vote again
on the edit page
I would first delete node_modules and then npm i
if you change node versions you normally have to recompile everything
split hazel
alright i'll try that
real helm
player.brawlers.forEach(e => {

@onyx summit it's still asking me to vote
onyx summit
bec you didnt define it @real helm
real helm
is define in the forEach
onyx summit
but its not defined xD
amber fractal
@real helm you're using it out of scope
real helm
But if put the message.channel.send the bots sends the results a lot of times
and I like that it only send the results 1 time
onyx summit
if you do var resultados; resultados will still be undefined

but every free hosting is bad 🙃
onyx summit
well a public free service is bad
opaque eagle
I get free Azure for a limited time cuz of GitHub Student
onyx summit
but free doesnt mean bad

so is Azure bad

azure isn't free though
they provide you a service without fees because you're a student and they can offer you education through that
earnest phoenix
🙃
earnest phoenix
aws (free trial) is limited
onyx summit
can you click on test again?

Now will it work for everyone else?

got everything working by deleting package.json aswell and instlaling every module one by one
i heard on discord.js master reactions are now seperate to the message object, how do i fetch the reactions object?

Hello. I'm trying to set up my bot to be configurable (with SQLite) but let's just say, the documentation isn't that helpful. I already have the connection set up
const connection = mysql.createConnection({
host : '#',
port : '3306',
user : '#',
password : '#',
database : '#',
charset : 'utf8mb4'
});
how do I check to see if a server's value is marked as, let's say 1 then run code? Also, how do I set that value in a command? Thank you! (By the way, please ping me if you respond!)
stone dust
@wooden lance iirc you’ll generally be interacting with the DB via a “cursor” object in your language of choice
Fetching a value from the DB will generally be done w a “SELECT” query and assigning will generally be done with an “UPDATE” query
if you haven’t used SQL before the queries aren’t too bad but the general pattern is using the cursor to make a query, then fetching the results as needed and acting on them
wooden lance
I haven't used databases before. And, I don't know what a select or update query is.
stone dust
ah np
wooden lance
I've tried using a db before, it didn't work.
stone dust
SQLite as well?
wooden lance
I haven't successfully got SQLite to work before either.
stone dust
ah
do you have a way to interact with the server in the command line?
or otherwise*
wooden lance
yes
stone dust
cool
winged thorn
With python at least
stone dust
@wooden lance and you haven't been able to get a response from it yet?
wooden lance
wait, the server (as in vps) or sql db?
stone dust
lol don't worry about it
being insecure about asking for help won't serve any benefits, you've gotta do it once or so
wooden lance
yeah
stone dust
i guess like
what resource have you been using to start up the sql DB so far
and where are you hosting it from as well (local or online or)
wooden lance
start the my sql server?
stone dust
yeah
wooden lance
it's up 24/7
stone dust
ah cool
wooden lance
it's managed by a company with my domain name
wooden lance
hosting it online
stone dust
is it mysql or sqlite?
wooden lance
mysql
stone dust
ah ok
do you have an interface like phpmyadmin that you can interact with it through or is it purely command line
wooden lance
wait, give me a sec, i do think i can get SSH access to it
stone dust
oh oh cool
additionally are there any errors that appear when you try to connect or is it just not responding at all
wooden lance
i haven't actually tried starting the bot up with that connection
stone dust
oh
you could try something like mysql workbench to access the DB
might be a good way to start fiddling around
stone dust
should be able to log into your database through that
and start creating tables and things
wooden lance
Okay
stone dust
if that works then would definitely suggest getting familiar with some common queries, select, insert, and update are the most common ones so knowing those is key
wooden lance
After I have done that, what code would I need to check to the db for a server's ID and a value? And if the value = 1 run code?
stone dust
that would most likely be a select query
you could build a table which tracks server ids along with a one bit flag
wooden lance
okay
@stone dust, this is gonna seem like a very stupid question, but what is the code for the select query? I have not used them before.
And the discord.js docs make no sense to me
valid frigate
how do i make the ShardingManager of the master process available to my sharded clients
wooden lance
to connect to the server? dont think so
stone dust
assuming the credentials and port num are correct it’s that or the server is unresponsive
or something else
wooden lance
hmm
can i have mysql on my bot's vps @stone dust?
as in a local server? so just on the same vps?
wooden lance
or quickdb
stone dust
yeah any of those should be fine to host locally assuming the port isn’t occupied
stone dust
No problem, sorry I couldn’t get to the bottom of it but best of luck!
wooden lance
thanks!
wooden lance
I am having some problems with quick.db on javascript. Anyone know what I can do to fix this?

nothing is returned by the function so gold isn’t set to anything
or there’s no error so console.log just logs something falsy
split hazel
I noticed
let e = array[i]```
makes it loop over a non existant element aswell, so if have 3 elements, it will loop over a 4th one that doesnt existdo i just add -1 to array.length?
earnest phoenix
or just
remove the operator that says to continue if i is equal to length
length starts with base 1
arrays with base 0
ergo length is always going to be +1

wooden lance
@warm marsh no, i didnt notice the response. do you know how to update node?
warm marsh
Depends, Are you on windows on Linux?
wooden lance
Linux
warm marsh
What version is currently running? node --version
I doubt node is the main issue behind that error but, If the distro of linux is Ubuntu try:
sudo apt-get purge node* then curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash - change 12 to a version you want, 12 being the latest once chosen run sudo apt-get install -y nodejs
Although, I don't think you need to purge the old one.
split hazel
What is the best way of limiting memory usage of my bot and sweeping useless things from memory? My memory climbs to about 1.1gb (from 600mb per shard) when it was online for around a day. im using discord.js
master
west spoke
I restart mine daily if that helps
earnest phoenix
auto reboot every day
split hazel
Is there a quick way of implementing that?
onyx summit
And as already mentioned earlier, you should limit the caching of messages if you don't really need them
You can define some cache options in the client constructor
split hazel
Will probably have to look at those in the docs then haha
And i really dont need to cache messages as i fetch them from api anyway
i also have a packet event that fires messagereactionadd, delete and remove if the message is uncached
onyx summit
messageCacheLifetime
messageSweepInterval
messageCacheMaxSize
I played a bit with those and my ram doesnt really rise anymore
split hazel
May i ask for your recommendation for the setting of those?
onyx summit
I have ```js
messageCacheLifetime: 60,
messageSweepInterval: 61,
messageCacheMaxSize: 20,
(master)
but I think you will have to try your ownstbh I just mixed some numbers I thought that might work
topaz fjord
lmao
split hazel
Are there also sweep options for users?
because i dont get users from cache anyway, i do it through the API
onyx summit
not that I know of, but you can sweep every collection. you would probably sweep them if their last message was like really old
split hazel
I should probably add user sweeping on an interval
onyx summit
you can define that sweeping in the client options
but you can sweep users yourself
so, theoretically you could sweep users if your ram gets too high (but prevent spamming it when your ram goes higher without the users fault)
inner jewel
i just keep everything cached
onyx summit
cool
quartz kindle
you can have it run with less than 100mb ram at 2k guilds if you know what you're doing
inner jewel
also, "high" memory usage can be just the gc being lazy
split hazel
Should i sweep users every couple hours?
inner jewel
and not running all the time to avoid pausing frequently
quartz kindle
for example, delete everything except guilds, then use the raw event for messages, and if message matches a command, you can optionally fetch the channel, the user, the member, and everything else you need
onyx summit
and how much its cleaning
split hazel
yeah i use the raw event for messagereactionadd, remove and delete
inner jewel
in garbage collected languages it's normal to have memory look like this https://i-was-scammed-by.dabbot.org/72dSsrz.png
(that's over a week, so it might look like memory is always rising but it isn't)
quartz kindle
depends on how much memory that is
onyx summit
I would recommend https://developer.ibm.com/node/monitoring-post-mortem/application-metrics-node-js/ do have stats (including gc stats)
inner jewel
for the last 6 hours, it looks like memory is only increasing
quartz kindle
if its 1gb ram at 1k guilds for example, then its not normal
inner jewel
but zooming out shows that's not the case
it goes from ~1.1GB to ~1.4 then drops back to 1.1
quartz kindle
the thing is that d.js caches a lot of things by default, most of them you might not actually need
inner jewel
out of 1.5gb allocated for the process
quartz kindle
so there is a lot of room for ram improvements
onyx summit
agreed, d.js is not bad, but without some tweaks it eats a lot of ram
quartz kindle
that you can do as the end user, even if they are techincally not suppoerted methods
with my method i could keep my bot stable at 80-90mb ram at 1.5k guilds
quartz kindle
my vps only has 1gb ram so.. xD
onyx summit
yeah I actually rented some overpowered shit
thought I would host some gameservers but 
earnest phoenix
still can't run a minecraft 1.14 server 🙃
you need a server farm to run a mc 1.14 server at this point to be honest, they made it so heavy
onyx summit
I think it will
earnest phoenix
(i was joking)
onyx summit
but my old vps wasnt able to run 1.13 becs of some fcking fish path calculations
maxed the cpu out
earnest phoenix
yeah 1.13 has a fuckton of performance issues
split hazel
actually do i need users cached for anything? I only fetch users through API
onyx summit
yeah I'm unsure too xD
ask in d.js support
but I don't think so
only reduces api calls (afaik)
earnest phoenix
actually do i need users cached for anything? I only fetch users through API
if your commands require a user to be provided as an argument, it would be preferred to have the user cached
that way you don't have to nag the command executor to use their id, rather you allow them to use their username etc
though caching users is irrelevant in guilds which have less than 100 members
split hazel
Wouldn't i just get everything through the member object?
quartz kindle
if you need to do any operation on a user, like kick/ban/dm/roles/etc, then you should cache them
split hazel
yeah i need for roles and dm so i should probs keep them
earnest phoenix
Wouldn't i just get everything through the member object?
but how will you get the member object if you don't have the id
quartz kindle
yes, but what you can do is also cache them as needed
or simply sweep them regularly
onyx summit
I would make it like this:
sweep allows a method to decide if they should be sweeped or not. you could check the last message, if its not set, delete the user, if its set and already a few hours old (check timestamp) delete him
earnest phoenix
the issue comes where the caches between your bot and a user's client are mismatched. a user can have another user in their client cache, but your bot maybe doesn't have that specific user in cache, so the bot wouldn't recognize the user if it was provided as an argument through a form of a username lets say
quartz kindle
you mean like using mentions?
earnest phoenix
mentions are doable
you can extract the id
however, it will cost you an api call to verify if the user actually exists or not
because someone can provide a dummy mention
discord.js seems to be really heavy on caching and honestly i don't know why, i used to keep every single member in 2.2k guilds cached (even in here) and the bot wouldnt peak over 500 mbs on discord.net
quartz kindle
yes, but you can fetch it once and then keep it in the cache, it costs a few calls, but its still better than running with hundreds of cached users that are never used
slowly your bot will get populated with users that are actually relevant and used, instead of trash
lul
but i think djs's goal is to minimize hitting the api as much as possible
even if it costs half of your machine's resources
or more
quartz kindle
well im still using the sweeping version in production, using around 200-300mb
but im gonna switch to the raw methods eventually
split hazel
I'm getting these when starting bot

they do
split hazel
That's weird, it's in the messageReactionAdd event

topaz fjord
reaction only passes two things https://discord.js.org/#/docs/main/master/class/Client?scrollTo=e-messageReactionAdd

following that, you're getting the .emoji.name prop from a User object
topaz fjord
no event in d.js passes client
onyx summit
he means a event handler
onyx summit
stop being so specific, everyone uses event handlers and everyone passes a client
are you using the raw event?

i am

I think I had a similar issue a year ago lol
can you show the part in the raw event where you define the things for the event and then emit it

});
}```can you try this:
module.exports = (client, packet) => {
if (!['MESSAGE_REACTION_ADD', 'MESSAGE_REACTION_REMOVE'].includes(packet.t)) return;
const channel = client.channels.get(packet.d.channel_id);
if (channel.messages.has(packet.d.message_id)) return;
channel.messages.fetch(packet.d.message_id).then(message => {
const emoji = packet.d.emoji.id ? `${packet.d.emoji.name}:${packet.d.emoji.id}` : packet.d.emoji.name;
const reaction = message.reactions.get(emoji);
if (reaction) {
reaction.users.set(packet.d.user_id, client.users.get(packet.d.user_id));
} else {
const emoji = new Discord.Emoji(client.guilds.get(data.guild_id), data.emoji);
reaction = new Discord.MessageReaction(message, emoji, 1, data.user_id === client.user.id);
}
if (packet.t === 'MESSAGE_REACTION_ADD') {
client.emit('messageReactionAdd', reaction, client.users.get(packet.d.user_id));
}
if (packet.t === 'MESSAGE_REACTION_REMOVE') {
client.emit('messageReactionRemove', reaction, client.users.get(packet.d.user_id));
}
});
}
i'll give it a shot
onyx summit
by the way that user thingy will rely on cached users
so if you really need that user it you would need to fetch that user
split hazel
i get the same error
its also preventing my bot from booting
i just noticed one shard booted but some of the others refuse to do so
hold on the error went away
now im getting discord is not defined
need to find that
now i'm getting
0|shards | at channel.messages.fetch.then.message (/root/events/raw.js63)``` @onyx summituff okay that happens if you copy and paste code from another context
my bad
maybe this
https://txtupload.cf/9DP#lf2qk
split hazel
now im getting "animated is not defined" and "data is not defined"
what i dont get is the exact same code works on glitch where i test the bot before i put it onto the vps
onyx summit
hm, I dunno why, but this worked good for me, sorry, then I can't help you
glitch good 
are the cache settings different?
split hazel
their the same
i guess i'll revert to my stable code until i figure out how to get it working
sacred spade
When you add your bot on Discord Bot List, it automatically adds it to the Discord. How would I do the same?
split hazel
well first your bot needs to pass the submission process
it then appears publicly on the website and gets invited here
if not your submission gets deleted and bot doesnt get invited

hi guys
im trying to make a custom prefix command, everything is ok
but i need to define the db.Fetch to functions.js
how can i do it ?
lusty dew
When would you use zlib-sync? When sharding or can you use it at any time?
ember atlas
Why is it saying my token is invalid when its not
ember atlas
no
lusty dew
Have you tried regenerating the token and using the new token?
ember atlas
i didnt make it
so idk how it works
but ive never had an invalid token error ever
lusty dew
Wait what language are you using
ember atlas
i think its js
lusty dew
You think?
ember atlas
like i just said
i didnt make it so idk how it works but ive never had an invalid token error ever
lusty dew
You shouldn't copy and paste code without understanding it first
lusty dew
Okay?
I'm confused as to how that has anything to do with this? You're still making the bot and don't even know if it's js
ember atlas
and this is why i dont come to this server for hlep
no one understands that everyone just forks modmail and starts it
thanks for trying

Someone know how if the user click on emoji reacted by a bot he get the user mentions or username?
Or something like this???
opaque eagle
What language and what library @earnest phoenix
amber fractal
Well considering he's in the Discord.js Official discord
I would assume d.js
Well the basic pseudo-code would be
listen/wait for reaction > if reacted mention user

@opaque eagle discord.js

Hi, i have a question.
I want my bot to run on multiple vps, but i have a big statistics database i cannot query remotely all the time from all shards. Each vps/shard should hence load and have only the information it neeeds for answering stats requests from the respective servers the shard is on. Each shard will also write new statistics into its local storage, andshoueld update the changes to the remote database perodically.
I was wondering, is there some known and beautiful solution to this? I am about to "manually" program this cache: An api for my remote database (mysql) to load and update saved records. Then some local storage solution (maybe some in-memory sql solution?) to load and run the actual queries on the vps machines.
carmine echo
is it a violation of tos to send people a dm once they've voted 3 times
trail dagger
no
carmine echo
epic
trail dagger
just dont spam down someones dm
short portal
anyone have know why my bot keeps changing its presence when the only time it changes it is when its ready. But it doesn't restart
i can send the code that does it
sour sage
Send it.
short portal
client.on('ready', () => {
console.log(`Logged in as ${client.user.tag}!`)
client.user.setActivity("people poke each other", { type: 'WATCHING' })
});
Nothing wrong there
short portal
the whole thing?
quartz kindle
yeah
short portal
this is my first time coding in js
earnest phoenix
that is so messy and unreadable
short portal
i can understand it. but yh i see what you mean
quartz kindle
is it on glitch/heroku?
short portal
glitch
earnest phoenix
i can already see a few issues; you should only have one event handler, switch case your commands in one handler instead, and don't use json as a database as it's more prone to data loss and corruption
short portal
im gonna move over to sqlite
earnest phoenix
you should try catch sending a dm to a user as it oftens fails due to the user not having dms enabled
short portal
i thought i did
quartz kindle
yeah there is room for improvement, but i dont see why it would be resetting its presence every 10 seconds aside from crashing/disconnecting
maybe after a code cleanup it will also fix itself
short portal
ok
quartz kindle
join all your on("message") together into a single on("message") event
short portal
ok
quartz kindle
i g2g out now
viral spade
Hey Tim please help me out on this, noone seems to know.
So i have a statistics bot and my bot/3shards(discordjs) an data(mysql) lie on the same server. I am at 3500 servers and i think my current build will not make more than 20k, as a loot of complex database queries are done every second already and the response time is also not great.
At some point i need to be able to horizontally scale on multiple vps. I intend to have a remote backup database and a local "cache", that is populated at startup (with records of the servers the respiective shard has), and periodically saved. This local cache should be an in memory database to increase response time (for calculating statistics).
Do you know of any tools/dbms to automatically achieve this "persitant-remote-inmemory-chache-backup behavior? Or do i have to implemnt it "manually", meaning write an api for my remote mysql database to pull and update the records, and write controller in my bot for populating and updating the in-memory database from/to my remote api?
short portal
ty for the help
quartz kindle
@viral spade you will probably have to set it up manually to fit your needs, but try using sqlite for a local process-specific database, and then flush it do the remote db once in a while
unkempt moon
Or use a time-series database like InfluxDB for the statistics data. That can easily handle statistics for 20k servers
Classic SQL databases are the worst for storing statistics of stuff 🤷
viral spade
ok thank you.
but i really wonder, is there no in-memory database system that 1 . is able to load from a remote disk in its own memory only the reocrds it needs and 2. has a persistance mode that is able to save the stuff back remotely automatically?
like many people must need something like this, no?
quartz kindle
only thing i can think of would be redis replication
unkempt moon
Time-series databases are good for your use case. I suggest you look at those
They're optimized for that
quartz kindle
and yes, many people need something like that, but that is something that is very implementation-specific, and should mostly be done manually
viral spade
i see.
that redis replication looks interesting and sounds like what i was looking for.
I will still do it manually,, thank you
so you would suggest sqlite for this?
will i be able to use all my mysql sql statements with sqlite just the same?
split hazel
Whenever I boot the bot & shards, i always get cannot read property emoji of undefined and then the shards crash, and pm2 reboots them and the cycle continues, from my message reaction add event file, it seems that my raw event isn't working on master, can someone take a look? https://hasteb.in/nacayito.js
quartz kindle
are you sure the error is coming from there? not sure why would you be receiving an empty packet
if you're sure the problem is there, you could just add if(!packet.d) { console.log(packet); return; }
that will stop the errors and give you some info about the packet to maybe find out why its empty
split hazel
I'll try that
quartz kindle
cpu yes, mem no
lusty dew
Oh
Okay well someone told me to just install it and it should work is that the?
True*
split hazel
After the emoji error I got
{ t: null, s: null, op: 11, d: null }������
after logging packet
if packet.d is missing
lusty dew
Do I just install zlib-sync and it will work?
Or do I have to do some stuff coding wise
quartz kindle
you just need to restart your bot in most cases
unless you use a process manager like pm2
lusty dew
Okay
split hazel
oh i think it logged the heartbeat because i put the logging before the if packet contains messagereactionadd stuff
quartz kindle
5% sounds normal
lusty dew
Ye
quartz kindle
mine is also at 5% with zlib, and 10-20% without zlib lul
quartz kindle
lmao
sinful lotus
with zlib-sync its 20%
lusty dew
Before it was at like 20 then when I installed zlib it jumped up to 60% now it’s down to 5%
A lot of jumping around eh
topaz fjord
@sinful lotus single shard 
quartz kindle
internal sharding
lusty dew
How does that work
sinful lotus
yes single process multiple ws shard
lusty dew
Ah okay
sinful lotus
lusty dew
Doesn’t sharing have an auto feature?
quartz kindle
1gb at 15k guilds is nice
lusty dew
I’ve seen stuff like shardCount: 'auto'
sinful lotus
my ws shards is auto
quartz kindle
yes, the auto option will fetch recommended shards
sinful lotus
I only specify my process
lusty dew
Someone told me actually 2-3 people told me auto wasn’t an option 
lusty dew
Is there a way to cut down on mem usage?
lusty dew
Actually is 100+mb normal for a bot in 19 servers?
sinful lotus
just d.js stuff
quartz kindle
yes
lusty dew
Okay
sinful lotus
specially if your bot is in here
lusty dew
I don’t think it is
quartz kindle
the node process itself will use 50-60mb
lusty dew
I have to use a separate website for hosting my mongodb
sinful lotus
then thats should be fine
lusty dew
Cause my friend doesn’t use mongodb so he doesn’t have a mongodb server running on his service
But that website only allows me to have 500mb and that’s it
quartz kindle
500mb is more than enough in most cases
unless you store files or images
my bot uses about 4mb for user/guild configuration and 600mb for images lol
lusty dew
The user collections if I ever get it working may become a problem in the future
Rn userData isn’t being written which is fine for now cause I’m not doing anything userwise Rn
Also my next question is how do I control caches?
split hazel
nothing gets logged @quartz kindle

lusty dew
I don’t know how to do that lol
quartz kindle
are you using master or stable?
lusty dew
master
quartz kindle
@split hazel is messageReadtionAdd.js the file you posted earlier?
split hazel
Nope, that was the raw.js file
or event shall i say
what confuses me is the same exact code works correctly on a test bot thats on glitch
quartz kindle
@lusty dew master has several different caches, such as client.users, client.channels, client.guilds, but most importantly, each guild has several caches itself such as guild.members, guild.presences, guild.roles, guild.emojis, etc...
all of those can be cleaned regularly to free up memory, specially if you dont use them in the first place
split hazel
line 16 in messsageReactionAdd is
if(reaction.emoji.name !== "🎁") return;
and using module.exports = async (client. reaction, user) => {
split hazel
how would that possibly happen
it works correctly on glitch, which has the same code
on a test bot thats in like 2 servers
lusty dew
@quartz kindle I don’t know how to do that, that’s my problem
I’ve never worked with caches didn’t know that you could reduce mem usage by cleaning caches until a few minutes ago lol
quartz kindle
@lusty dew all collections have a sweep function
<collection>.sweep(function)
so you can do client.users.sweep(function to decide what to sweep and what not to sweep)
the function works the same way as any other iterator, like you would use in a .map or something
or a .find
lusty dew
Would I have to do that for every cache?
quartz kindle
yes
quartz kindle
yes
for example, this is something i tested before
guild.channels.clear();
guild.members.clear();
guild.roles.clear();
guild.voiceStates.clear();
guild.presences.clear();
guild.emojis.clear();```assuming you dont need to use any of that content
carmine echo
is it ok to send a user a dm once they've voted?
Even if they haven't interacted with the bot in the past
lusty dew
Lava link uses voice states at some point or I think I do I can’t remember what I used in all my music commands
quartz kindle
you have to make a lot of tests
because sometimes you might need something that you're not aware you do
for example if you use members, or set roles
and in most cases you will also need channels
presences is usually what most people complain uses a lot of memory and not a lot of people need it
lusty dew
I use members and set roles
And I mess with channels a lot but idk if it counts as like message.channel.send?
quartz kindle
yes it does
lusty dew
Okay so I shouldn’t sweep channels members or roles?
quartz kindle
if you need something you deleted, you need to re-fetch it when you need it
for example, if you delete channels, then you need to send a message to a channel
you can do this
let channel = client.channels.get(id) || client.channels.fetch(id)```another good idea is to not clear stuff that has been used recently
for example .clear() clears everything, but .sweep() only clears what you specify in the function
you can for example clear users that havent sent a message in a while
by comparing lastmessage timestamps
lusty dew
O.o okay
quartz kindle
i had a more complete example somewhere, let me find it
let OLD_SNOWFLAKE = Discord.SnowflakeUtil.generate(Date.now() - 3600000);
for(let guild of client.guilds.values()) {
guild.channels.sweep(t => t.type !== "text" && t.type !== "dm");
guild.members.sweep(t => t.id !== guild.me.id && (!t.lastMessageID || t.lastMessageID < OLD_SNOWFLAKE));
guild.roles.sweep(t => t !== guild.id);
guild.voiceStates.clear();
guild.presences.clear();
guild.emojis.clear();
}
client.channels.sweep(t => t.type !== "text" && t.type !== "dm");
client.users.sweep(t => t.id !== client.user.id && (!t.lastMessageID || t.lastMessageID < OLD_SNOWFLAKE));
for(let channel of client.channels.values()) {
if(channel.permissionOverwrites) {
channel.permissionOverwrites.clear();
}
}```clear channels that are not text or dm channels
clear members and users that havent sent a message in the last hour
and some other stuff
but for each of those, you need to test how it impacts your bot, and make corrections if needed
so implement those carefully, one by one
lusty dew
How would I test?
quartz kindle
@carmine echo should be ok i think
@lusty dew use your bot normally and see if and where it crashes lul
carmine echo
That's good thanks
lusty dew
Oof Okay xD
I’ll look into that later rn I think everything is fine how it is thanks for teaching me how to do this though!

yeah i knew that would happen i just tried to see if at least 1 shard managed to go online before the memory limit
quartz kindle
how many guilds are you running on again?
split hazel
3.2k
quartz kindle
hmm
lusty dew
What’s the guild limit before you need to start sharding?
quartz kindle
2.5
split hazel
k
lusty dew
Okay
split hazel
its strange how the test bot works fine
lusty dew
Anyway I can automate sharding for when it reaches that limit to start sharding?
split hazel
yeah d.js will spawn the recommended shards
topaz fjord
Yes
lusty dew
Might as well get the code over with instead of having to worry about it later
topaz fjord
You can also post to the discord API to see what they recommend
split hazel
im still trying to realise why my reaction objects are coming back empty
lusty dew
Wait couldn’t I just do this:
client = new Discord.Client({shardCount: 'auto'})
Or smth
topaz fjord
no
lusty dew
Hm
quartz kindle
@split hazel
topaz fjord
You woukd have to use https://discord.js.org/#/docs/main/stable/class/ShardingManager @lusty dew
lusty dew
Mk
quartz kindle
put the packet type comparison inside the reaction check
onyx summit
I think he is on master
onyx summit
Ye then that works
quartz kindle
if(reaction){
reaction.users.set();
if(packet.t === ...) {}
else if(packet.t === ...) {}
}```Also nice pfp
quartz kindle
yes, the way it is right now, you're still sending the reaction event even if there is no reaction
so you get an empty reaction on the event listener
split hazel
ahh that would make sense
since the bot is constantly receiving reaction packets all the time from the 3.2k guilds
or other packets
quartz kindle
welp ig2gnow
lusty dew
Can’t you sweep messages with the sweepMessage method?
Jkjk
But does it sweep old messages or new messages?
onyx summit
You have to pass a lifetime
lusty dew
Ah mk
onyx summit
In seconds, and messages that are older than this get removed
lusty dew
Trying to find ways of reducing mem usage seems like clearing caches is the only good way?
onyx summit
like client.sweepMessages(100) will sweep all messages that are older than 100 sec
You can pass some stuff in the client constructor
so your bot caches less messages
lusty dew
Wym
onyx summit
Gimme 10 sec to turn on my pc
lusty dew
Kk
pale marsh
Optimize your code a bit and make sure you don't have memory leaks as well
lusty dew
I haven’t noticed any memory leaks
onyx summit
your bigggest memory leak is lavalink anyway
lusty dew
Really?
onyx summit
not really a memory leak but it eats the most ram
onyx summit
const client = new BClient({
shardCount: await Discord.Util.fetchRecommendedShards(process.env.BTOKEN, 500),
presence: {
status: 'idle',
activity: {
name: 'Shard Starting',
},
},
messageCacheLifetime: 60,
messageSweepInterval: 61,
messageCacheMaxSize: 20,
});
the part to cache less messages:
messageCacheLifetime: 60,
messageSweepInterval: 61,
messageCacheMaxSize: 20,
Ah so I can add that type of stuff in my client constructor to help reduce cached messages?
onyx summit
and e.g. my bot has 38 731 channels, meaning it could cache up to ~ 8 Million Messages
lusty dew
Woah
onyx summit
if my maths isnt shit (it is)
but I think thats right, 38731 channels * maximal 200 messages = 7.746.200 Messages
lusty dew
My bot only reads 433 channels lol
Okay well brb while I add in the message cache string
Thing*
How would I know if it’s working?
onyx summit
uhhh, you can eval in any channel (preferable #commands ) how many messages it has cached message.channel.messages.size
lusty dew
Okay
My bot isn’t even in here I don’t think
Okay nvm
Why did it not work earlier when I tried using I
It*
Hmph
onyx summit
change the prefix tho xD
lusty dew
Wym?
onyx summit
your bots prefix is -, and by running it in here a lot of bots will respond
so if you can, change its prefix in here
onyx summit
lusty dew
None of its active rip
Except for when me and the other dev talk I’m it
In*
Hm
@onyx summit should I just change the prefix globally?
👀
onyx summit
nah
onyx summit
I mean, you don't really have to care bout ram yet
lusty dew
I know but I wanna be prepared lol
onyx summit
my server is not really busy yet 
lusty dew
Lol I just don’t want to cause problems for you
lusty dew
I don’t know how to add that btw
onyx summit
its on my github readme
