# rtimer
|
|
Persistent timer with set and clear
|
|
|
|
## Install
|
|
|
|
npm install rtimer
|
|
|
|
## Usage
|
|
|
|
rtimer has two instance methods `set` and `clear`.
|
|
- `set` restart the timeout
|
|
- `clear` clear the current timeout, timeout can be restarted again after clear
|
|
- `callback` property contains the callback method
|
|
- `delay` property contains the timeout delay
|
|
|
|
## Example
|
|
|
|
```js
|
|
var rtimer = require('rtimer');
|
|
|
|
var start_time = +new Date();
|
|
|
|
// create new timeout with 1000ms delay
|
|
var timeout = rtimer(function() {
|
|
// this will be triggered after 1500ms
|
|
// because of the reset
|
|
var t = (+new Date() - start_time);
|
|
console.log('time ' + t + ' ms');
|
|
|
|
// change timeout delay and callback
|
|
timeout.delay = 500;
|
|
timeout.callback = function() {
|
|
console.log('Hello World!');
|
|
};
|
|
// reset timeout
|
|
timeout.set();
|
|
}, 1000);
|
|
|
|
// reset timeout after 500ms
|
|
setTimeout(function() {
|
|
timeout.set();
|
|
}, 500);
|
|
|
|
```
