Firebase Extensions help you reduce time spent on development, maintenance, and growth of your app.
When you find a Firebase Extension that solves a need for your app or project, all you do is install and configure the extension. With extensions, you don't spend time researching, writing, and debugging the code that implements functionality or automates a task for your app or project.
Also, to install an extension, your project must be on the Blaze (pay as you go) plan. You will be charged a small amount (typically around $0.01/month) for each instance of an extension you have installed, in addition to any charges associated with your use of Firebase services.
Official Firebase extensions
The official Firebase extensions are developed and tested by Firebase and Firebase Extensions partner services. These extensions are reliable and secure.

View the source code of an extension
To find a link to the source code for one the official Firebase extensions, click Learn more on the extension's card on the Firebase Extensions product page or in the Firebase console.
Contents of an extension's source code
An extension's source directory includes:
extension.yaml file — Contains the extension's metadata and defines the resources created, the Google APIs and access roles required for operation, and any user-configured parameters (environment variables) for the extension
functions directory — Contains the files for the source code for the extension
README file — Lists the extension's metadata (but in more human-readable format) as well as the content from the PREINSTALL file
PREINSTALL file — Describes how the extension works, any necessary pre-installation tasks, configuration requirements, and details about the extension
POSTINSTALL file — Describes specific usage instructions and any further integration requirements
Resources for an extension
Every Firebase project contains several types of "resources". Project resources can include things like deployed Cloud Functions, database instances, Cloud Storage buckets, and Cloud Scheduler jobs.
When you install an extension, Firebase creates new extension-specific
resources in your project (specifically, Cloud Functions). These resources are
defined in the extension's specification file,
as the resource type
firebaseextensions.v1beta.function), and they are
required by the extension to operate.
Note that, if you uninstall an extension, all the resources that Firebase created specifically for that instance of the extension to operate (like a set of functions) are deleted. However, the following are not deleted:
Any artifacts created by the extension (like stored images).
Any other resources in your project, like a database instance or Cloud Storage bucket. Even if the extension interacted with these other resources, they are not extension-specific, so they aren't deleted if the extension is uninstalled.
