And for what? Again - there is a swath of use cases which would be hard without React and which aren’t complicated enough to push beyond React’s limits. But there are also a lot of problems for which I can’t see any concrete benefit to using React. Those are things like blogs, shopping-cart-websites, mostly-CRUD-and-forms-websites. For these things, all of the fancy optimizations are optimizations to get you closer to the performance you would’ve gotten if you just hadn’t used so much technology.
Today, we'll look at measuring React component render performance with the React Profiler API, measuring interactions with React's new experimental Interaction Tracing API and measuring custom metrics using the User Timing API.
Game-changing impact of GatsbyJS on performance, accessibility and scalability of modern webapps, and how to integrate it with complex business requirements — be it for a brand new project or an existing ReactJS codebase.
In this article, I will attempt to demystify the high-level strategies of the most popular CSS-in-JS libraries, discuss the performance issues they may introduce on occasion and finally consider techniques that we can employ to mitigate them.
"After a lot of trialing we have settled (for now at least) on moving our rendering tier to React and Emotion. This will doubtless generate a new set of challenges, but we expect that they should at least solve the set we have right now."
"If you’ve been waiting to try out React, Gatsby is a great place to start! If you’re struggling to make your React app fast, try switching to Gatsby! If you’re tired of using technology X to build websites and have a huge secret crush on React, well, Gatsby is waiting with open arms"
"We have tried to answer the unanswerable: What framework should I use? […] A framework is nothing more than an embodiment of some patterns, integration of some technologies, and source code to help make our web applications easier to build and maintain."
"We can do that by utilizing Lazy Loading. Lazy loading is a great way to optimize your site, and it does that by splitting your code at logical breakpoints, and then loading it once the user has done something that requires, or will require, a new block of code. This speeds up the initial load of the application and lightens its overall weight as some blocks may never even be loaded."
