nohooks

> Compose reactive hooks without additional libraries.

Installation

``bash
$ npm i nohooks --save
`

How it works?

The nohooks library provides a single module with several low-level hooks, e.g.

`js
import { createContext, useState } from 'nohooks';

async function main() {
const scope = createContext(() => {
const [value, setValue] = useState(3);
if (value > 0) setValue(value - 1);
console.log(value);
return value;
})();

console.log(scope.result === 3);
await scope.defer();
console.log(scope.result === 0);
}
main();
`

3
true
2
1
0
true

> Notice scope.result returns the initial value immediately, after waiting it returns the last computed value.

$3

Calling createContext(render[, cb]) will return a function later used to compute values.

It also accepts a second argument that is called to set the scope.set method, for triggering updates.

$3

- onError(cb) — Capture unhandled exceptions.
- useMemo(cb[, deps]) — Memoized callback result.
- useEffect(cb[, deps]) — Fires a synchronous callback.
- useRef([defaultValue]) — Returns a persistent unique reference.
- useState([defaultValue]) — Returns a value/setter from the any given value.

> Notice that no passing deps will trigger the given callback on every iteration, use [] to fire it once.

$3

- clone(obj) — Returns a copy from any given value.
- equals(a, b) — Returns true if a and b` are equal.
