Is this using Railpack? Or a Dockerfile?

[grave perch]

Nixpacks

[pine osprey]

Could you switch to Railpack? Nixpacks is deprecated

You can change the Node version using the RAILPACK_NODE_VERSION env variable
In your case 22 should work

[grave perch]

Made the changes you asked and got a new error:

copy /app/browser
0ms
ERROR: failed to build: failed to solve: failed to compute cache key: failed to calculate checksum of ref y1pgn8pxd568xbja5xn91zoyk::w1xsba7b24bhjtku3fy42w143: "/app/browser": not found

This is my first time using railpack I really don't know what to expect

[pine osprey]

You can switch back to Nixpacks then, and use NIXPACKS_NODE_VERSION instead

[grave perch]

Faild again, error:

npm warn config production Use --omit=dev instead.

npm warn EBADENGINE },

[pine osprey]

Slightly unfortunate, NIXPACKS_NODE_VERSION to 22.12

[grave perch]

Faild again:

[pine osprey]

23 it is

[grave perch]

NIXPACKS_NODE_VERSION set to 23, went back to node v18

[pine osprey]

I'm at a loss then

[astral bone]

If you have to switch off Railpack, switching to a Dockerfile would be preferred over switching back to Nixpacks.

[pine osprey]

(Railpack is was switched to from Nixpacks)

[grave perch]

Can you help with dockerfile template I can use I really dont understand docker

[astral bone]

I can't, but the community can!

Since you got the error
"/app/browser": not found
when you switched to
Railpack
, you can try to solve it by modifying your
angular.json
file to change the
outputPath
of the build.
Switch back to
Railpack
and try this one:
{
"projects": {
"lanhsahn-sis": {
"architect": {
"build": {
"options": {
"outputPath": "."
}
}
}
}
}
}
Try to change it to just
browser
if it doesn't work, or whatever base folder corresponds to
/app/browser
.

This is the structure when built, if it helps

New reply sent from Central Station thread:

In this case, change the outputPath to
"."
. This way Angular will create the
browser
folder in your project root. You will need to add
browser
to
.gitignore
so you don't push build outputs to your repo.

The image you provided shows that you haven't changed the outputPath to
"."
!

If changing the outputPath doesn't work, keep it as it was, and try setting
RAILPACK_BUILD_CMD
to
npm run build && mv dist/lanhsahn-sis/browser .
in your environment variables.
