use-less

React hooks that help you do what you already did, with more indirection

Warning: this package is ready for production use because of 1.x.x version

Install

npm install @pveyes/use-less

APIs

All the functionalities are available inside named import. Because it's written in typescript, you can be sure these hooks are free of bugs.

useProps

React already provide

useState

props

use-less

useProps

import { useProps } from '@pveyes/use-less';

function Component(props) {
  const actualProps = useProps(props);
  // you can finally use the actual component props
  return 
;
}

In cases where your props is computationally expensive, you can use lazy initializer, similar to how it works in

useState

import { useProps } from '@pveyes/use-less';

function Component(expensiveProps) {
  const props = useProps(() => expensiveProps);
  // you can finally use the actual component props
  return 
;
}

useConstructor

If you don't like the way React uses tuple for its state hooks and you feel like setting state on constructor is the way to go, you can use

useConstructor

import { useConstructor } from '@pveyes/use-less';

function Component() {
  // If you're feeling nostalgic, you can use Cyrillic character
  // to name your variable thіs without v8 yelling at you
  const thіs = useConstructor(function constructor() {
    this.state = {
      text: string;
    }
  });
  // It feels so good to use this.state & this.setState
  // RIGHT? RIGHT???
  return (
     thіs.setState({ text: '' })}
    />
  );
}

Yes, you need to use normal function, not arrow function.

useDerivedStateFromProps

Moving to React hooks means you lose one of the most powerful React API:

getDerivedStateFromProps

gDSFP

use-less

useDerivedStateFromProps

uDSFP

import { useDerivedStateFromProps } from '@pveyes/use-less';

// if you're familiar with redux, you'll be familiar with this as well
function mapPropsToState(props) {
  return {
    value: props.value,
    onChange: () => void 0,
  };
}
function Component(props) {
  const state = useDerivedStateFromProps(props, mapPropsToState);
  return ;
}

useRenderProps

With hooks, you see less and less render props pattern being used.

use-less

useRenderProps

import { useRenderProps } from '@pveyes/use-less';

function Component(props) {
  const renderProps = useRenderProps(props);
  return renderProps(props => 
);
}

useHOC

Another thing that's missing since hooks era is Higher Order Component. One that was praised for being powerful is now starting to be abandoned. Fortunately, you can still use HOCs using

useHOC

import { useHOC } from '@pveyes/use-less';
import withLegacy from './hoc';

function Component(props) {
  const renderHOC = useHOC(withLegacy);
  return renderHOC(hocProps => 
);
}

This is even better than just using HOC, there's no more props naming conflict! This is the power of composition between hooks, HOC and render props!

useGlobalContext

The main issue with React Context is you can only get value that the Provider gives you, or its default value. What if you want to access global value? With the rise of SSR, you need to be sure you call correct global

console

useGlobalContext

It works in SSR and browser without any configuration!

import { useGlobalContext } from '@pveyes/use-less';

function Component(props) {
  const { console } = useGlobalContext();
  console.log('It works!');
  return null;
}

FAQ

• Does it work with concurrent mode

Yes, all this hooks should work in concurrent mode. Our example uses

React.StrictMode

• Can I really use this in production?

Yes, version 1.x.x means it's already stable and ready to use in production

• Why is it

  @pveyes/use-less

  and not

  use-less

  ?

Because there's already

useless

• Is this a joke?

What do you think?
