functions-loader

functions-loader is a utility package designed to automatically load Firebase Cloud Functions from files and folders within the functions directory. This simplifies the process of organizing and deploying your cloud functions by dynamically importing them based on the file structure. It specifically loads files with the .f.js extension.

Installation

To install functions-loader, you can use npm or yarn:

Usage

To use functions-loader, you need to require it in your index.js or main.js file where you initialize your Firebase functions. The package will automatically load all functions from the functions directory that have the .f.js extension.

Example

Create your functions directory structure:

functions/
├── index.js
├── helloWorld.f.js
└── user/
    └── createUser.f.js

Initialize functions-loader in your index.js:

// functions/index.js
const { loadFunctions } = require("firebase-function-tools-preview");

// Load all functions from the 'functions' directory
loadFunctions(__dirname, exports, true);

Define your cloud functions in separate files with the .f.js extension:

// functions/helloWorld.f.js
const functions = require("firebase-functions");

module.exports = {
  helloWorld: functions.https.onRequest((request, response) => {
    response.send("Hello, World!");
  }),
};

// functions/user/createUser.f.js
const functions = require("firebase-functions");

module.exports = {
  createUser: functions.auth.user().onCreate((user) => {
    // Handle user creation
  }),
};

Demo

You can find a complete example of how to use functions-loader in the demo folder of this repository. The demo includes a sample project structure and demonstrates how to set up and use the package to load Firebase Cloud Functions.

With this setup, functions-loader will automatically import and register all the functions defined in the functions directory and its subdirectories that have the .f.js extension.
