If you use server rendering, keep in mind that neither useLayoutEffect
nor useEffect
can run until the JavaScript is downloaded.
You might see a warning if you try to useLayoutEffect
on the server. Here's two common ways to fix it.
If this effect isn't important for first render (i.e. if the UI still looks valid before it runs), then useEffect
instead.
function MyComponent() {
Firstly, Create React App is good. But it's a very rigid CLI, primarily designed for projects that require very little to no configuration. This makes it great for beginners and simple projects but unfortunately, this means that it's pretty non-extensible. Despite the involvement from big names and a ton of great devs, it has left me wanting a much better developer experience with a lot more polish when it comes to hot reloading, babel configuration, webpack configuration, etc. It's definitely simple and good, but not amazing.
Now, compare that experience to Next.js which for starters has a much larger team behind it provided by a world-class company (Vercel) who are all financially dedicated to making it the best DX you could imagine to build any React application. Next.js is the 💣-diggity. It has amazing docs, great support, can grow with your requirements into SSR or static site generation, etc.
