kaychaks / autopack Goto Github PK

since a project's production build takes more time than mere starting the development server the daemon should not stop the existing running server. However, it should in some way overlay information on the running app that a new image is being built. This would require runtime code injection to the running application.
also we need to have some way of incremental code replacement of the built artefacts unless the build tool already supports that. One way is to volume mount the dist folder to the docker container rather than bundling it and only rebuilding the image if there is any change in the package.json.

The [NodeJS buildpack](https://github.com/paketo-buildpacks/nodejs) which is a set of collaborating buildpacks is very generic and hence does lot of tasks which are not required for autopack. This leads to the build process taking a lot of time.
Collaborating buildpacks of NodeJS does not provide any way to change the start command of the final image. They set the same to npm run start or yarn start. This is not going to work for autopack since react-script start launches the webpack dev server. For autopack we need to build the React proeject and then launch it using some simple Node static app [serve](https://github.com/vercel/serve)r like Vercel's serve
Creating a custom buildpack set using only the relevant collaborating buildpacks would require using the Paketo's Go libraries like [Packit](https://github.com/paketo-buildpacks/packit). Using the same would mean including one more component to the current Rust based tool.

Install node (other system level s/w like SSL certs etc.)
    this should ideally be following these Paketo buildpacks - [Node Engine CNB](https://github.com/paketo-buildpacks/node-engine), [Yarn CNB](https://github.com/paketo-buildpacks/yarn), [Environment Variables CNB](https://github.com/paketo-buildpacks/environment-variables), [Image Labels CNB](https://github.com/paketo-buildpacks/image-labels), [CA Certificates CNB](https://github.com/paketo-buildpacks/ca-certificates)
Install yarn (if required)
npm install or yarn install
    take inspirations from [Yarn Install CNB](https://github.com/paketo-buildpacks/yarn-install), [NPM Install CNB](https://github.com/paketo-buildpacks/npm-install)
