Node.js plugin fails to run corepack when using nodejs-slim

[apgrucza]

What happened?

Recently nodejs-slim changed to no longer include corepack as a default output. This breaks the Node.js plugin, which tries to run corepack when DEVBOX_COREPACK_ENABLED is true.

A workaround is to use a flake reference so that the additional corepack output can be specified (this requires the nodejs plugin to be explicitly added):

  "packages": [
    "github:NixOS/nixpkgs/nixpkgs-unstable#nodejs-slim_24^out,corepack"
  ],
  "include": [
    "plugin:nodejs"
  ]

But there are drawbacks with this workaround:

• You cannot pin the package with a version string
• It fails if you have already explicitly added another built-in plugin (due to Cannot explicitly add multiple built-in plugins #2790)

Steps to reproduce

1. devbox create --template node-yarn
2. cd node-yarn
3. devbox rm nodejs
4. devbox add nodejs-slim
5. devbox shell --pure

Output:

✓ Computed the Devbox environment.

bash: corepack: command not found
bash: yarn: command not found

Command

      "yarn install"
    ],
    "scripts": {
      "run_test": "yarn start"
    }
  }
}

A better workaround is to just add a corepack package:

  "packages": [
    "nodejs-slim@24",
    "corepack_24@latest"
  ],
