Hey Devs! 👋

This is the final post in our series on optimising React applications, and it's time to reveal the juicy results! We've been hard at work, and the performance improvements are pretty dramatic. Let's dive into the numbers and see how much faster our app has become.

**
📊 The Results and Impact: Quantifying a 70% Faster Load and 80% Quicker Build**

We started with a set of initial performance metrics, and after implementing code splitting, lazy loading, and caching strategies, the difference is night and day.

Here's a quick recap of what we set out to improve:

  • Page Load Time: How long it takes for users to see and interact with our app. ⏳
  • React Build Time: How long it takes for us, as developers, to build the app. 🛠️

📈 Performance Metrics Comparison

⚡️ Page Load Time: A User's Delight

We've achieved an approximate ~70% reduction in page load time! 🚀 To measure this, we used a combination of browser developer tools and performance testing tools. This improvement means:

  • Lower bounce rates: Users are less likely to leave a site that loads quickly. 📉
  • Increased conversion rates: A faster site improves user experience, making them more likely to complete desired actions. ✅
  • Happier users: Nobody likes waiting for a slow website! 😊

A faster loading time translates directly to a better user experience and improved business metrics. It's a win-win! 🏆

⚙️ React Build Time: A Developer's Dream

Our React build time has been slashed by approximately 80%! 🤯 We measured this using our build tools, and the impact on our development workflow is significant:

  • Faster iteration cycles: We can see the results of our code changes much more quickly. ⏩
  • More frequent deployments: Shorter build times enable us to deploy updates more often. 🚀
  • Reduced CI/CD pipeline duration: Our overall software delivery process is now more efficient. ⏱️
  • More productive developers: Less time waiting for builds means more time for coding! 🧑‍💻

🛠️ Key Tools and Technologies

To achieve these gains, we leveraged several key tools and technologies:

  • CRACO: To customize our Create React App configuration. ⚙️
  • webpack: For optimizing our JavaScript modules. 📦
  • React's lazy loading: To load components on demand. ⚛️

🎉 Conclusion: A Faster Future for Our App

Our performance optimisation journey has been a resounding success. We've significantly improved both the application's performance and our development team's efficiency. By focusing on key areas like code splitting, lazy loading, and caching, we've created a faster, more enjoyable experience for our users and a more efficient workflow for our developers.
