Implementing Sentry in Micro-Frontend Architecture (React, TypeScript)

Micro-frontend architecture has gained popularity in recent years as a way to break down large monolithic applications into smaller, more manageable parts. With the rise of TypeScript and React, many developers are now using these technologies to build their micro-frontends. However, one challenge that arises when working with multiple micro-frontends is error handling and monitoring. In this blog post, we will explore how to implement Sentry, a popular error tracking tool, in a micro-frontend architecture using React and TypeScript.

What is Sentry?

Sentry is an open-source error tracking tool that helps developers monitor and fix errors in their applications. It provides real-time error tracking, performance monitoring, and release tracking, making it an essential tool for any development team. By integrating Sentry into your micro-frontend architecture, you can easily track errors across all your micro-frontends and gain valuable insights into your application’s performance.

Step 1: Setting up Sentry

The first step is to set up a Sentry account and create a new project for your micro-frontend architecture. Once you have created a project, you will be provided with a unique DSN (Data Source Name) that you will use to configure Sentry in your micro-frontends.

Step 2: Installing Sentry SDK

To start using Sentry in your micro-frontends, you need to install the Sentry SDK. In a React project, you can install the Sentry SDK by running the following command:

npm install @sentry/react @sentry/tracing

This command installs the necessary packages to integrate Sentry into your React application.

Step 3: Configuring Sentry

Once you have installed the Sentry SDK, you need to configure it with your unique DSN. Create a new file called sentry.ts in your micro-frontend project and add the following code:

import { Integrations } from '@sentry/tracing';
import { init } from '@sentry/react';

const dsn = 'YOUR_UNIQUE_DSN';

export const configureSentry = (): void => {
  init({
    dsn,
    integrations: [new Integrations.BrowserTracing()],
    tracesSampleRate: 1.0,
  });
};

Replace YOUR_UNIQUE_DSN with your actual DSN provided by Sentry.

Step 4: Initializing Sentry

In your micro-frontend’s entry file (e.g., index.tsx), import the configureSentry function from the sentry.ts file and call it to initialize Sentry. Here’s an example:

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import { configureSentry } from './sentry';

configureSentry();

ReactDOM.render(
  
    
  ,
  document.getElementById('root')
);

With this setup, Sentry will start capturing errors and sending them to your Sentry project.

Step 5: Capturing Errors

Now that Sentry is configured and initialized in your micro-frontend, you can start capturing errors. Sentry automatically captures unhandled exceptions, network errors, and console errors. However, you can also manually capture errors using the Sentry.captureException method. Here’s an example:

import * as Sentry from '@sentry/react';

try {
  // Your code that might throw an error
} catch (error) {
  Sentry.captureException(error);
}

This code snippet captures the error and sends it to Sentry for further analysis.

Conclusion

By following these steps, you can easily implement Sentry in your micro-frontend architecture using React and TypeScript. Sentry provides powerful error tracking and monitoring capabilities, allowing you to identify and fix issues in your micro-frontends more efficiently. With real-time error tracking and performance monitoring, you can ensure a seamless user experience and improve the overall quality of your application.

Implementing Sentry in a micro-frontend architecture is a crucial step towards building robust and reliable applications. By monitoring errors and performance across all your micro-frontends, you can proactively identify and resolve issues, leading to a better user experience and higher customer satisfaction.
