my start command sh

I believe the issue is in the final image that the build is producing

This is output from the build, as last steps

[railpack] merge $install:composer, $prune:node, $build

This seems to be removing node from the final build

and because my main project is PHP, its not considering node to be worth to keep it.

I added this env

RAILPACK_PRUNE_DEPS="false"

NODE_RUNTIME="true"

RAILPACK_NO_PRUNE="true"

but nothing seems to be working

Heya, can you try setting RAILPACK_NODE_VERSION ?

See our railpack docs for more help: https://railpack.com/config/file

I set
RAILPACK_NODE_VERSION=22

same result

As a work around (after couple of days of search and trying multiple methods)

I added this script which installs and rebuild node deps in my start script

# Install Node.js from NodeSource (adjust version if needed)
echo "Installing Node.js ..."
curl -fsSL https://deb.nodesource.com/setup_18.x | bash -
apt-get update && apt-get install -y nodejs

# Install dependencies and build
echo "Installing npm dependencies ..."
npm install

echo "Building assets ..."
npm run build

This worked, but I don't like this solution

Oh this is to install Node and rebuild on every start? Is it being reliable for you?

Why don't you try to build a custom Docker image with PHP and Node?
