Intro

In this episode of Syntax, Scott and Wes talk about what they wish existed in React!

DevLifts - Sponsor

Refactor your body with DevLifts. They have a few different programs: 1) fit.start (normally $19/month) has a few options (lean, bodyweight, and strong). Workouts are delivered via email each month, with access to a Slack community for questions and accountability. 2) Premium (normally $199/month) is a custom-tailored option, where you get your workouts and nutrition advice after answering a questionnaire. They also check in with you each week via Slack to see how it's going and make changes if necessary. Get 50% off fit.Start plans with code SYNTAX and 50% off Premium with code TASTY.

Show Notes React

03:53 - Unmount delay for animation

06:20 - Suspense with SSR released (or not because I think they are shelving it)

• Dan's tweet: https://twitter.com/dan_abramov/status/1259614150386425858

09:24 - File based components

• Like Svelte and Vue
• This would look like a file with a special scoped tag per page.

11:50 - Prevent Default shortcuts

13:00 - No more useIsoLayoutEffect

• useLayoutEffect on SSR should just work without a custom hook
• Simple data fetching strategy based on promises

15:52 - Recommended hooks

• E.g. "here is the best way to do things"
• Official list of best practice hooks

18:25 - A good form strategy

• Bind inputs to state directly without any change handlers
• Inputs and forms all around need more magic - it's painful

20:43 - Write once deploy everywhere

• Not likely ever
• E.g. automatic transformation into react-native (obviously not going to happen)

22:28 - Compile time directives

• https://github.com/bukharim96/directive-x

25:11 - Slots instead of children

• Allows for things like named slots more explicit than children

JSX

26:44 - Removal of htmlFor, className and all other abominations of html

29:09 - Import Raact from React for JSX to work

• Soon will be fixed https://github.com/babel/babel/pull/11154
  • react-require

32:31 - Better conditional / if statement syntax

33:09 - Fragments by default

• Just do it for us - the error message already knows

33:54 - Automatic key ids

• If mapping an object, check for common _id or id

36:36 - Simple scoped CSS built in

37:29 - Short hand for props with same name is prop={prop}

39:00 - Prop interpolation without backticks: name="$first $last"

• Or just backticks without brackets name=${first} ${last} instead of name={${first} ${last}}

Tooling

39:43 - Story for typescript/prettier/babel

40:11 - Automatic a href client side routing

41:51 - Scaffolding and component generation
