Firebase is an software development platform launched in 2012 and acquired by Google two years later.
Cloud Firestore is another interesting Firebase service.
In turn, queries scale based on the size of the results rather than the data set size.
This allows applications to scale from the beginning without waiting until the moment in which needs exceed capacity.
Google will give you the option to enableGoogle Analyticsfor your new project.
To illustrate this task, we will see how to use the Firebase Realtime database service.
A Create Database button will appear on the right.
punch it to create your first database in Firebase.
Next, you will have to choose between several geographic location options for your new database.
go for the one that is closest to your users.
This is an important aspect to minimize the latency of your API, particularly in real-time apps.
The next step is to configure the basic security rules for your database.
you’re free to start with the test mode option not to complicate security tweaks at the beginning.
you’ve got the option to always create rules later to set the security configuration with greater granularity.
The next step is to write your API code.
To do that, you will need to initialize the Firebase hosting and functions on your local computer.
To develop a web API, you’ve got the option to opt for JavaScript.
If you will use package dependencies, install them with npm inside the functions folder.
Then you’re free to start writing the code for your functions.
The URL is located in the Realtime Database section of the Firebase console.
The URL contains your project ID and a region for the HTTP function.
If you do not have a Blaze subscription, the deploy command will not display your API URL.
It is basically a secure sandbox to test your API functionality before sending it to a production environment.
To emulate your functions or test your utility locally, run firebase emulators:start.
You must have Java installed to be able to use Firestore Emulator.
If you dont have it, you could install it fromhere.
By default, this URL will be localhost:4000, but it may vary on each machine.
You will also get a full URL for your HTTP function.
To test the function, copy the URL returned by the emulator, adding any necessary parameters (e.g.
?itemid=1) and enter it in a new tab of your surfing app.
The results of the API execution will appear in the Emulator Suite UI.
In the Logs tab, you will see new logs indicating that the itemQuery() function was executed.
If your function generates new data in your Firestore database, you will see it in the Firestore tab.
How is that possible?
Simply because apps associated with Firebase rank better in search rankings than other applications.
Also, take into account Firebases app indexing API.
This tool improves the search rankings of app links and helps users find the desired content.
