What is @firebase/performance?

The @firebase/performance package is part of the Firebase suite, designed to help developers collect and analyze performance metrics of their web and mobile applications. It provides automatic and custom tracing capabilities that allow developers to measure the performance of their applications in real-time.

What are @firebase/performance's main functionalities?

Automatic Tracing

Automatic tracing automatically collects performance data about your app's most common tasks. This feature requires no additional code after initialization and helps in monitoring performance out-of-the-box.

import { getPerformance } from 'firebase/performance';

const perf = getPerformance();
// Automatic traces are started and stopped by Firebase itself.

Custom Tracing

Custom tracing allows developers to manually define specific parts of their application to measure performance metrics. This is useful for measuring performance of custom operations not automatically traced by Firebase.

import { getPerformance, trace } from 'firebase/performance';

const perf = getPerformance();
const myTrace = trace(perf, 'customTraceName');
myTrace.start();
// Code to trace
myTrace.stop();

Network Request Performance

This feature automatically captures performance metrics of network requests made by the application. It helps in understanding the time taken by the app to make and complete requests, and to optimize them if necessary.

import { getPerformance } from 'firebase/performance';

const perf = getPerformance();
// Network performance data is automatically collected and available in the Firebase console.
