I'm looking for a tool to run runserver and npm start in one command with multiplexed output

For development? Or for production? Why must it be multiplexed? What OS ?

[solid pike]

I think you have to use two terminals

[solid pike]

Python manage.py runserver on one end and npm start on the other

[wintry lagoon]

Just for development

It needs to be multiplexed for debug output

Currently my team are opening two terminals and running two programs

I want one command that does both

[rain yoke]

Use docker compose?

[wintry lagoon]

We don't use docker

Also the multiplexing doesn't work well with vite

and breakpoint() in Django

[rain yoke]

Write a script then, but the solution you're looking for is docker compose 🙃

Or tmuxp with two panes 🤓

[wintry lagoon]

Oh that looks good

[ripe sapphire]

No need to write the script anymore, I use "White Noise" it runs both npm and Django together very easy to use

what is multiplexed output? i've used docker image with prebuilt vuejs app and fastapi running on single gunicorn server as static content before , should work with django as well

Docker compose is the only common tool i have seen doing it - if you have multiple containers running it will merge the stdout log output from all containers into one terminal/view, and color code them so you can separate the output. So you can watch the output from all containers at once.

I think you want to see two logs in the same screen sorted by timestamp.
You can redirect the stdout/stderr of two programs to the same file, then you can see it all together:

program_log1 > /tmp/debug.log
program_log2 >> /tmp/debug.log
tail -f /tmp/debug.log

This is a simple shell script, you do not need more complex programs to see two logs at the same time.

Anyway, docker and docker compose is a good friend to do this and more things.

I have the same structure in development environment for webpack + django dockerized project, docker is the best option for this case.

[wintry lagoon]

No not logs, stdout and stderr of two processes merged

I want arbitrary processes without docker

[final roost]

it is the same 2> for stderr and > for stdout

[wintry lagoon]

Can you show a complete runable example?

[wintry lagoon]

For development

[wintry lagoon]

Ah interesting but it was published 6 years ago, I'm looking for something a little more recent and in C, Rust or Python

[wintry lagoon]

This won't work because program_log1 won't ever terminate

[final roost]

test it, it works

[upbeat smelt]

Oh wow! I had no idea it was abandoned! 😬

[wintry lagoon]

No it won't work because program_log1 will never finish so there's no way to run program_log2
