React timer component (higher-order)

A React higher-order timer component

Keep your components simple, testable and composable by using higher-order components. This higher-order timer component will re-render your component at the desire rate (in milliseconds).

This higher-order component takes care of when to call render on your component, so your component has only to care about the rendering logic.

A higher-order component is just a function that takes an existing component and returns another component that wraps it.

Read about higher-order components here (applies to deku as well): Mixins Are Dead. Long Live Composition.

Applications

• Countdowns (time remaining)
• Timers (time elapsed)
• Forcing updates / refresh of time-based contents

Installation

npm install --save react-timer-hoc

Usage

Create a new component by wrapping your component with timer HOC. Alongside the properties you specify, the created component will receive a tick property, the specified delay value and a stop function.

import React from 'react';
import ReactDOM from 'react-dom';

function myComponent({ tick, stop, delay }) {
    return <div>Started { tick * delay }ms ago.</div>
}

const Timer1 = timer(1000)(myComponent);
const Timer2 = timer(2000)(myComponent);

ReactDOM.render(
    <div>
        <Timer1 />
        <Timer2 />
    </div>,
    document.getElementById('app')
);
