Cloud Functions For Firebase.

Firebase is google’s application development platform for creating mobile and web applications. It helps you build, improve, and scale your app. It provides you a large number of services that developers will usually have to make themselves. Still, developers really wouldn’t want to build available services because they’d instead concentrate on the product experience themselves. This covers such aspects as analytics, authentication, databases, configuration, file storage, push messaging, and the list goes on. The platforms are hosted in the cloud and scale with little to no effort on the developer’s part.

Firebase began to assume that applications can be created with mostly client code because it was simpler and quicker in many ways. However, there are still some instances where server programming is required, such as executing trustworthy code, authenticating to a third-party API, or running battery-intensive services. In these cases, you’ve had to stick up for your server — so often. That is the reason why they introduced Cloud Functions for Firebase.

Cloud functions allow you to write small bits of JavaScript, deploy them to Google’s cloud platform, and run them in response to events from across the Firebase ecosystem. This was the most needed update since the Firebase was released. The ability to enhance and link Firebase functionality using Cloud Functions makes Firebase more efficient, enabling you to do much more for your app without worrying about servers.

What should I do with Cloud Functions?

Cloud Functions allows developers to access Firebase and Google Cloud events, along with flexible processing resources to execute code in response to these events. Although it is anticipated that Firebase apps will use Cloud Functions in specific ways to fulfill their unique specifications, common use cases can fall into these areas, such as:

Notify users anytime something exciting happens.

Give a welcoming e-mail when the user logs in.

Send a confirmation SMS when the customer generates a new account.

Perform the sanitization and cleaning of the servers.

Conduct extreme activities in the cloud instead of in your app.

Remove inactive Firebase accounts regularly.

Give a bulk e-mail to consumers.

Aggregate and summarize results quarterly.

Process the queue with the jobs to be completed.

Integrate with third-party services and APIs, and many more.

Here are just a couple of the many functions you can do with the available integrations:

1.Firebase Analytics — This integration requires a function to be activated when a particular conversion event is triggered. You can create automatic development and retention features for your mobile applications without ever upgrading your client code. To cite an example,

You can send a survey request to customers after they update their app.

You can send a coupon code message to users who have just made a transaction.

2.Firebase Authentication — The integration requires a feature to be activated when a new user is generated or removed. For example,

You can give an invitation to greet new users as soon as they sign up.

You can clean up the relevant user data from your Realtime Log after a user account is removed.

3.Firebase Realtime Database — Integrating Firebase Realtime Database enables you to trigger a feature when creating, updating, or erasing data on a specific database’s path. For example,

You can send an FCM message when the data is written to the database.

You can moderate and exclude offensive language from the data in the database.

4.Cloud Storage — Cloud Storage functionality helps you activate a feature when an object is written, modified, or removed within a specific storage bucket. To cite an example,

You can resize and transform files anytime a new file is uploaded to the Cloud Storage bucket.

You can moderate violent images uploaded to Cloud Storage through the Cloud Vision API.

5.HTTP Endpoint — The integration provides the Cloud Function a URL that can be used as a webhook. These functions are activated when a request is made to its unique, protected URLs. For example,
