Improve and Optimize Performance of React Apps With Reactime V7.0

Learn about Reactime

What is Reactime?

When it comes to React applications, one of the most challenging aspects of optimizing your application is state management debugging. Nowadays there are so many ways to handle the state of your application — Hooks, Context API, Redux, etc. — but not too many tools that are fully compatible with it all.

Reactime helps centralize the complex state debugging process. Reactime was nominated for the Productivity Booster award at the 2020 React Open Source Awards

Prior to Reactime v.7.0, Reactime was known simply as a time-travel debugging tool for React applications. With the new latest version, we have expanded its functionality and increased its accuracy. Now, Reactime 7.0 is a performance tool for React applications, including frameworks like Gatsby and Next. Not only does it help manage and understand the state of your application, but you can now also visualize the rendering frequency of your components. Additionally, Reactime now only runs in development mode, which allows you to enhance its speed without slowing down your applications.

Let’s elaborate on what we improved and added with this new release of Reactime.

New Features of Reactime v7.0

• New rendering feature + rendering time for each component
• Compatibility with Gatsby and Next
• Runs on single and multi-page applications
• Brand new minimalist and intuitive design for UI
• Improved algorithm in terms of time complexity for the performance tab
• Works in development mode only and doesn’t affect the speed of your app

How It Works

Utilizing the React Fiber reconciliation, Reactime records and caches snapshots of your application’s state every time it is changed and so enables you to time travel through previous states. It allows the developer to visualize a tree graph of the state changes, calculate the diff between snapshots, and have a playback option that helps identify the changes of the state step by step. Additionally, you can analyze each component’s rendering frequency and speed with our performance tab.

I have been using React JS in my projects for quite some time now and am used to managing routing in my app using the react-router package. I have always been keen on having as little dependencies in my apps as possible, so, I always felt perturbed by the use of this particular package in simpler apps which did not have complex routes.
