Problem

Firebase Cloud Functions do not support a monorepo setup. The folder pointed to by firebase.json -> functions -> source is copied over in a container. The container is run on every Cloud Function cold start. When the container is run, the npm dependencies are installed. This means that we need a package.json in the folder. To support deterministic builds a package-lock.json should also be included. The dependencies are installed from the npm registry. Therefore local dependencies (other packages in the monorepo) are not supported.

Solution: bundle local dependencies

See packages/fnc/build.js.

Instructions:

• npm i
• npm run build:bundle -w @demo/fnc
• Explore packages/fnc/dist folder
