Introduction to LogRocket

LogRocket is a frontend application monitoring solution that helps developers understand problems that users run into, by recording videos of user sessions along with console logs, JavaScript errors, stack traces, network requests, and browser metadata.

This comprehensive guide will dive into several useful LogRocket APIs with clear code snippets and an application example that leverages these APIs for efficient error monitoring and user session recording.

Setting Up LogRocket

  
    import LogRocket from 'logrocket';
    LogRocket.init('your-app-id');
  

You start by initializing LogRocket with your application ID.

Log Custom Redux Actions

  
    import LogRocket from 'logrocket';
    import reduxPlugin from 'logrocket-redux';
    LogRocket.init('your-app-id');
    LogRocket.use(reduxPlugin());
  

LogRocket can log custom Redux actions to help you debug state changes.

Identify Users

  
    LogRocket.identify('USER_ID', {
      name: 'John Doe',
      email: 'john@example.com',
    });
  

Utilize LogRocket’s identify feature to associate user metadata with session recordings.

Recording Custom Events

  
    LogRocket.track('Custom Event', {
      category: 'User Behavior',
      label: 'Clicked Signup Button',
    });
  

Track important custom events for detailed user journey insights.

Recording Network Requests

  
    LogRocket.getSessionURL(function(sessionURL) {
      console.log('User session URL:', sessionURL);
    });
  

Get session URLs for further inspection of user activities.

Masking Sensitive Data

  
    LogRocket.init('your-app-id', {
      dom: {
        inputSanitizer: true,
      },
    });
  

Mask sensitive data during recording for enhanced user privacy.

Integrating with an Application

Below is an example of a simple React application that integrates various LogRocket APIs:

  
    import React, { useEffect } from 'react';
    import LogRocket from 'logrocket';
    import reduxPlugin from 'logrocket-redux';
    import { createStore } from 'redux';
    import { Provider } from 'react-redux';
    import rootReducer from './reducers';
    
    const store = createStore(rootReducer);
    LogRocket.init('your-app-id');
    LogRocket.use(reduxPlugin({ store }));
    
    const App = () => {
      useEffect(() => {
        LogRocket.identify('USER_ID', {
          name: 'John Doe',
          email: 'john@example.com',
        });
      }, []);
      
      const handleEvent = () => {
        LogRocket.track('Custom Event', {
          category: 'User Behavior',
          label: 'Clicked Signup Button',
        });
      };

      return (
        <Provider store={store}>
          <button onClick={handleEvent}>Sign Up</button>
        </Provider>
      );
    };
    
    export default App;
  

This sample application sets up LogRocket for Redux logging, user identification, and custom event tracking.
