React 18 미리보기

즉시 사용 가능한 개선점

코드의 변경 없이 React 18로 업데이트하자마자 얻을 수 있는 개선점에 대해서 간단히 이해해보자.

Automatic batching for fewer renders

  제목에서도 알 수 있는 것처럼 간단히 설명하자면, React 18 이전에는 오직 이벤트 핸들러 안에서 발생한 setState만 모아서 처리 했지만, React 18 이후부터는 promise, setTimeout 등에서 발생한 연속적인 setState도 모아서 처리될 수 있도록 개선되었다는 내용이다.

  위 기능을 피하고 싶다면 react-dom의 flushSync api를 이용하면 모아서 처리하지 않고 하나의 setState가 바로 re-render를 일으키도록 명시적으로 코드를 추가할 수 있다.

Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

1. Use ESM yourself. (preferred)
   Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
3. Stay on the existing version of the package until you can move to ESM.

type IsAnyUnknown<T, Y, N> = unknown extends T ? Y : N;
  
// when T is never, Y is returned, otherwise N
type IsNever<T, Y = true, N = false> = [T] extends [never] ? Y : N;

// when T is a tuple, Y is returned, otherwise N
// valid tuples = [string], [string, boolean], 
// invalid tuples = [], string[], (string | number)[]

CMake를 왜 쓰는거죠?

The Rules of React

All libraries have subtle rules that you have to follow for them to work well. Often these are implied and undocumented rules that you have to learn as you go. This is an attempt to document the rules of React renders. Ideally a type system could enforce it.

What Functions Are "Pure"?

A number of methods in React are assumed to be "pure".

On classes that's the constructor, getDerivedStateFromProps, shouldComponentUpdate and render.

Customizing VS Code

I followed the instructions in this blog post Multiple Fonts: Alternative to Operator Mono in VSCode, but did not see any changes made to VS Code. After digging a bit, I discovered that all the CSS class names had changed. They’re now e.g. .mtk13, .mtk16 { … }.

Gotchas

• Ensure it’s a file URL e.g. { "vscode_custom_css.imports": [ "file:///Users/Brian/Desktop/vscode-style.css" ] }
• If you move the location of your file and update your user settings with the new location, you will need to disable and enable custom CSS cmd+shift+p.
• Also, anytime you change the style in your custom CSS file, you need to disable, then re-enable the extension.
