For beginners and for small scale applications, building an API backend and deploying it on the web can be a tedious task sometimes. If you choose to deploy it in a Virtual Machine in any of the cloud services like Google Cloud, Azure, or AWS, it can be daunting to set up.

One more downside to this is that since a virtual machine is an Infrastructure as a Service (IaaS), you’d be charged by the hour. You would essentially be charged for the time the VM is running, regardless of whether you’re making API calls or not.🙁

Enter, Serverless Functions…

No, it’s not like you think. Serverless functions do run on a server. But they’re called so because it eliminates the need for managing the software and hardware of the server. It is as simple as copying and pasting code and hitting deploy.

Sounds amazing, right? Let’s build a basic serverless API and deploy it through the firebase CLI.🔥

Prerequisites and Installation

Let’s get started. First, please install Node from here.

  • Now, once you’re done installing, let’s initialize our project.
  • Create a new directory for your project.
  • Open up a terminal, cd to the project directory, and type npm init
  • For now, accept the default options and let the project be initialized.
  • Install firebase by typing, npm install -g firebase-tools
  • Awesome!

Login and Initialize

Login and Validate

  • Login to Firebase by entering this command, firebase login
  • It will open a window in the browser. You can log in there.
  • Return to the terminal once you’ve logged in.


Let’s initialize a project in firebase.

  • Type firebase init
  • When it asks for what CLI features are needed, just choose Firebase Functions for now.
  • It will ask to connect to a project, create a new one, and drop in a name of your choice.
  • Choose JavaScript as the language for functions.
  • Choose to not use ESLint, as we don’t really need it now.
  • Now, our firebase project is ready!

Write the API

Now, let’s jump into the programming part.

In your project directory, the functions/index.js file is the entry point of your function. That’s the file that will always be executed. We have to edit only this file. So let’s start editing!

A brief explanation of this code

  • Lines 1-4 -> We import the needed packages
  • Lines 6-9 -> We initialize express, and set options for CORS handling.
  • Lines 11-14 -> This is our main api route, /hello. If we send a request to /hello, we’ll get a server response that says, “hello!'
  • Lines 16-19 -> This is our main api route, /world. If we send a request to /world, we’ll get a server response that says, “world!'
  • Line 21 -> This line is a Firebase Functions method that says that the function would be triggered if a HTTP Request is sent to the function URL.

Thus, we have a very basic API with two routes. Let’s go on and deploy it!

First though, we have to specify the function dependencies in our package.json. Now proceed to the package.json file within the functions folder, and append the following lines within the dependencies object.


Let’s deploy our function! Enter the command, firebase deploy in the terminal.

You have successfully deployed the API! Yay! Now get your API URL from the Firebase Console.

Test, test, test

Now that we have deployed our API, we also need to test whether it behaves properly. For this, we can use the amazing API testing tool Postman, which is a GUI tool for API testing, or CURL, which is a CLI utility for sending HTTP requests.

Install and open Postman, and with the request type as GET, enter the URL of your function, and try sending a request to “/world”.

You’d get a response that looks something like this:

The API works really well. You could also try to send a request to “/hello” and check it out.

Note: There’s also a way by which you can deploy your API locally and test it before deploying it to the web by running the command, firebase emulators:start. Check these docs for more info -> Link


We have successfully written and deployed a super simple API onto Firebase! We could also make use of Firebase’s Firestore and other features and integrate them into functions. We can create powerful APIs and deploy them with the command or a click of a button!

Android Quirks

You may have to run this command if you're having issues building for an Android device:

Drupal Firebase

iOS Quirks

You'll need to be running at least [email protected] to get the build to compile properly for iOS. To see your current version of the iOS platform:

Then if it isn't running at least 4.0.1, then run this command:


Sending a Push Notification

In Drupal, first go to admin/config/services/push_notifications and verify that a token has been registered for yourdesired device(s). If there is a token registered, then go to admin/config/services/push_notifications/message andfill out the form to send a push notification to your desired platform(s).

Receiving a Push Notification

To handle the receipt of a push notification, implement this hook in your custom DrupalGap module's .js file:

When a push notifications is received, developers can take action as they need. The example above simply shows the push notification in an alert dialog.

Real World Examples

Send a push notification to display a node

In this example, a Drupal admin will be able to send a push notification that when clicked by the end user will display a particular node in the app.

In a custom Drupal module, alter the push notifications form so you can include a node id in the message payload:

Now in a custom DrupalGap module, take action when the push notification is received and send the user to view the node in the app:

Drupal Base Dir

That's it! Now when a user clicks the push notification on their device, it'll open the app and display the node.
