Firebase CLI with monorepo support

This is a fork of the firebase-tools which integrates isolate-package as part of the functions deploy command in order to support monorepo setups.

Alternatively, you can manually configure isolate as part of the predeploy step of your configuration, but having the process integrated and only running as part of the deploy command is essential if you want to have live code updates when running the Firebase emulators locally during development with a watch task.

I suspect it will take some time before the Firebase team would agree to make isolate an integral part of the toolchain and that is why I have published this fork to be available on NPM.

The fork is pretty much identical, and the integration with isolate-package does not affect any existing functionality, so I do not think there is a reason to worry about things breaking. I will sync the fork with the upstream firebase-tools on a regular basis. The fork versions will match the firebase-tools versions for clarity.

Installation

It is probably best to install this as a local dependency on whatever package you want to deploy to Firebase, as opposed to using a global install. This way the forked binary does not interfere with the original one on your system, and you can easily use the fork on one project will still using the original one on others.

It is recommended to use pnpm over npm or yarn. Apart from being fast and efficient, PNPM has better support for monorepos, and the the lockfile isolation code is solid and works in parallel for multiple packages, unlike NPM

pnpm add firebase-tools-with-isolate -D

Or run the equivalent for NPM or Yarn.

!! Do not forget to remove/uninstall the original firebase-tools package from your repository if you have it installed as a local dependency on your project, because otherwise that binary might get precedence over the forked one, and npx firebase deploy will execute the wrong one.

Commands

Installing the fork locally provides you with the same firebase command but in order to execute a command on the command line you prefix it with npx like npx firebase deploy.

If you are using the commands as part of a package.json script, npx is not required, because scripts already prefer locally installed binaries when available.

Configure

You have to opt-in to the functions isolate process by setting functions.isolate: true in your firebase.json. For example:

{
  "functions": {
    "source": ".",
    "runtime": "nodejs20",
    "predeploy": ["turbo build"],
    "isolate": true
  }
}
