@hashiprobr/react-use-refs v1.0.12

react-use-refs

A React Hook for using multiple refs with a clean sintax

This hook receives an object and creates a ref for each one of its properties, using the received value as the initial one. It returns a proxy object in which the property names are the same, but each value is the .current property of its respective ref.

The role of this proxy object in functional components is analogous to the role of this in class components: you use its properties to preserve values between renders, similar to how you would use instance fields.

Example

You just need a single call of useRefs...

import React from 'react';

import useRefs from '@hashiprobr/react-use-refs';

export default function MyComponent() {
    const refs = useRefs({
        myInt: 1,
        myStr: 'hello',
        myObj: { a: 2, b: 'world' },
    });

    function change() {
        refs.myInt = 10;
        refs.myStr = 'HELLO';
        refs.myObj.a = 20;
        refs.myObj.b = 'WORLD';
    }

    return (
        <div>
            <p>{refs.myInt}</p>
            <p>{refs.myStr}</p>
            <p>{refs.myObj.a}</p>
            <p>{refs.myObj.b}</p>
        </div>
    );
}

...instead of multiple calls of useRef.

import React from 'react';

import { useRef } from 'react';

export default function MyComponent() {
    const myIntRef = useRef(1);
    const myStrRef = useRef('hello');
    const myObjRef = useRef({ a: 2, b: 'world' });

    function change() {
        myIntRef.current = 10;
        myStrRef.current = 'HELLO';
        myObjRef.current.a = 20;
        myObjRef.current.b = 'WORLD';
    }

    return (
        <div>
            <p>{myIntRef.current}</p>
            <p>{myStrRef.current}</p>
            <p>{myObjRef.current.a}</p>
            <p>{myObjRef.current.b}</p>
        </div>
    );
}
