- Build a Server-rendered ReactJS Application with Next.js
- Top 5 Practices to Boost React Performance
- A React And Preact Progressive Web App Performance Case Study: Treebo
- In this course we well see just how quickly next.js makes the process of building server-rendered ReactJS applications by creating and deploying an application that loads blog posts from the Google Blogger API.
- Along the way well learn about many of the amazing features Next.js provides for us out of the box, such as route prefetching and code-splitting, thus allowing us to spend more time developing and virtually no time setting up our environment.
- Additionally, well learn about the core concepts behind the framework and see how we can leverage them to create dynamic routes and integrate Material-UI on the server.
- We wont have to worry about using any specific architecture to handle state, instead we will just pass our data as ReactJS using Next.js lifecycle hook.
- Throughout this course we will see why Next.js has gained such an amazing reputation as a minimalist framework by supplying users with pretty error messages.

- Lets imagine that this how React builds its tree: – – But what when a components state changes, the method returns a different tree of React elements.
- I personally prefer Chromes developer tools because there are tons of features under the Performance tab that let you profile and debug your application with ease.
- To create a performance profile for your application, follow the steps below: – – For a more detailed overview, Id recommend Ben Schwarzs article on Debugging React.
- It gives you a visualization of the props before and after and notifies you about components that shouldnt have been rerendered.To install the tool, run – – Add this code into your index.js file.
- This is the default behavior, and, since React updates only the relevant DOM nodes, this process is usually fast.
- In Treebos case, using server side rendering dropped their first paint time to 1.1s and first meaningful paint time down to 2.4sthis improved how quickly users perceived the page to be ready, they could read content earlier on and it performed slightly better at SEO in tests.
- This had the impact of dropping their first interactive times since the current routes chunk was already in the cache when webpack made a call to fetch it after their initial bundles finished executing.
- In addition it: – Diffs Virtual DOM against the DOM – Allows props like class and for – Passes (props, state) to render – Uses standard browser events – Supports fully async rendering – Subtree invalidation by default – – In a number of PWAs, switching to Preact has led…
