Is it possible to create Firebase real-time database triggers in files other than index.js?

Is it possible to split a large index.js file into multiple files in order to better organize the code? Specifically, can Firebase triggers be written in separate JavaScript files? If so, could you please provide guidance on how to do this properly?

child.js

exports.testFunction = functions.database.ref(`/test/`).onWrite((snap, context) => {
  console.log(snap.val());
  return null;
});

...

index.js

const childFunction = require('./child.js');

...

Answer №1

To effectively organize your code, you can store different functions in separate files and then import them into your main index.js file. Here's how you can do it:

1.) Create a new JavaScript file called 'modA.js'

module.exports = {
  func1: function () {
    // implementation of function 1
  },
  func2: function () {
    // implementation of function 2
  }
};

2.) Import the module into your index.js file:

var moduleA = require('./modA');

3.) Use the imported functions in your index.js like this:

moduleA.func1();
