# pretty-time [](http://badge.fury.io/js/pretty-time) [](https://travis-ci.org/jonschlinkert/pretty-time)
|
||
|
|
|
||
|
|
> Easily format the time from node.js `process.hrtime`. Works with timescales ranging from weeks to nanoseconds.
|
||
|
|
|
||
|
|
## Install
|
||
|
|
|
||
|
|
Install with [npm](https://www.npmjs.com/)
|
||
|
|
|
||
|
|
```sh
|
||
|
|
$ npm i pretty-time --save
|
||
|
|
```
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
```js
|
||
|
|
var pretty = require('pretty-time');
|
||
|
|
|
||
|
|
var start = process.hrtime();
|
||
|
|
var time = process.hrtime(start);
|
||
|
|
console.log(pretty(time));
|
||
|
|
//=> 3μs
|
||
|
|
```
|
||
|
|
|
||
|
|
## API
|
||
|
|
|
||
|
|
By default, when no time increment is given as the second argument, the closest timescale is used (e.g. _most granular without being less than zero_).
|
||
|
|
|
||
|
|
**Examples:**
|
||
|
|
|
||
|
|
```js
|
||
|
|
pretty([1200708, 795428088]);
|
||
|
|
//=> '2w'
|
||
|
|
|
||
|
|
pretty([800708, 795428088]);
|
||
|
|
//=> '1w'
|
||
|
|
|
||
|
|
pretty([400708, 795428088]);
|
||
|
|
//=> '5d'
|
||
|
|
|
||
|
|
pretty([70708, 795428088]);
|
||
|
|
//=> '20h'
|
||
|
|
|
||
|
|
pretty([12708, 795428088]);
|
||
|
|
//=> '4h'
|
||
|
|
|
||
|
|
pretty([3708, 795428088]);
|
||
|
|
//=> '1h'
|
||
|
|
|
||
|
|
pretty([208, 795428088]);
|
||
|
|
//=> '3m'
|
||
|
|
|
||
|
|
pretty([20, 795428088]);
|
||
|
|
//=> '21s'
|
||
|
|
|
||
|
|
pretty([0, 795428088]);
|
||
|
|
//=> '795ms'
|
||
|
|
|
||
|
|
pretty([0, 000428088]);
|
||
|
|
//=> '428μs'
|
||
|
|
|
||
|
|
pretty([0, 000000088]);
|
||
|
|
//=> '88ns'
|
||
|
|
|
||
|
|
pretty([0, 000000018]);
|
||
|
|
//=> '18ns'
|
||
|
|
```
|
||
|
|
|
||
|
|
### Minimum time increment
|
||
|
|
|
||
|
|
_(All of the following examples use `[6740, 795428088]` as the hrtime array.)_
|
||
|
|
|
||
|
|
This value is passed as the second argument and determines how granular to make the time.
|
||
|
|
|
||
|
|
**Examples**
|
||
|
|
|
||
|
|
```js
|
||
|
|
pretty(time, 'h');
|
||
|
|
//=> '2h'
|
||
|
|
|
||
|
|
pretty(time, 'm');
|
||
|
|
//=> '1h 52m'
|
||
|
|
|
||
|
|
pretty(time, 's');
|
||
|
|
//=> '1h 52m 21s'
|
||
|
|
```
|
||
|
|
|
||
|
|
