expressjs-framework

The ExpressJS extension streamlines the process of building ExpressJS application rocks.

It facilitates the installation of ExpressJS application dependencies, including Node and NPM, inside the rock. Additionally, it transfers your project files to /app within the rock.

The ExpressJS extension is compatible with the bare and ubuntu@24.04 bases.

Project requirements

There are 3 requirements to be able to use the expressjs-framework extension:

  1. The application should reside in the app directory.
  2. The application should have a package.json file.
  3. The package.json file should define the start script.

parts > expressjs-framework/install-app > npm-include-node

You can use this field to specify the version of Node to be installed. For example:

parts:
  expressjs-framework/install-app:
    npm-include-node: true
    npm-node-version: 20.12.2

For more examples of the npm-node-version key, see the NPM plugin documentation.

If you don't customise the version of node, it will be installed from the Ubuntu package repository.

parts > expressjs-framework/runtime: > stage-packages

Installing additional runtime packages is currently unsupported.
