Read about [Hooks](https://reactjs.org/docs/hooks-intro.html) feature. ## Installation ``` npm i use-timer ``` With [Yarn](https://yarnpkg.com/): ``` yarn add use-timer ``` ## Demo [![Netlify Status](https://api.netlify.com/api/v1/badges/3be3466e-4bc9-46f1-89b0-9b09910cc20b/deploy-status)](https://app.netlify.com/sites/use-timer/deploys) 🚀 Try last production version on Netlify! https://use-timer.netlify.app/ ## Usage ### Basic timer ```tsx import React from 'react'; import { useTimer } from 'use-timer'; const App = () => { const { time, start, pause, reset, status } = useTimer(); return ( <>

Elapsed time: {time}

{status === 'RUNNING' &&

Running...

} ); }; ``` ### Decremental timer ```tsx const { time, start, pause, reset, status } = useTimer({ initialTime: 100, timerType: 'DECREMENTAL', }); ``` ### Timer with end time ```tsx const { time, start, pause, reset, status } = useTimer({ endTime: 30, initialTime: 10, }); ``` ### Advance time This works for all types of timer (incremental and decremental). ```tsx const { time, start, advanceTime } = useTimer({ initialTime: 20, }); start(); advanceTime(10); console.log(time); // 30 ``` ## Callbacks Some callback functions can be provided. ### When time is over ```tsx const { time, start, pause, reset, status } = useTimer({ endTime, onTimeOver: () => { console.log('Time is over'); }, }); ``` ### When time is updated ```tsx const { time, start, pause, reset, status } = useTimer({ endTime, onTimeUpdate: (time) => { console.log('Time is updated', time); }, }); ``` ## Configuration The configuration and all its parameters are optional. | Property | Type | Default value | Description | | ------------ | -------- | ------------- | -------------------------------------------------------------------------------------- | | autostart | boolean | false | Pass true to start timer automatically | | endTime | number | null | The value for which timer stops | | initialTime | number | 0 | The starting value for the timer | | interval | number | 1000 | The interval in milliseconds | | onTimeOver | function | | Callback function that is called when time is over | | onTimeUpdate | function | | Callback function that is called when time is updated | | step | number | 1 | The value to add to each increment / decrement | | timerType | string | "INCREMENTAL" | The choice between a value that increases ("INCREMENTAL") or decreases ("DECREMENTAL") |
