firebase-tools-with-isolate

Firebase CLI with monorepo support

This is an experimental 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.

In the meantime I will try to keep this fairly in-sync with updates to the original firebase-tools repository. The published versions of the fork will be kept the same as the original firebase-tools package, so you can easily see how up-to-date it is.

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.

npm install firebase-tools-with-isolate --save-dev

Personally I would advise you to try PNPM for monorepo setups.

pnpm add firebase-tools-with-isolate -D

At the moment, isolate-package only supports generating isolated lockfiles for PNPM and NPM, but if you depend on Yarn you can always choose to deploy to Firebase without a lockfile, similar to other workarounds people have been using.

!! 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
  }
}
