timeago.js

a tiny / simple library

What ?

timeago.js is a tiny(2kb) library used to format date with `*** time ago`. eg: '3 hours ago'. No dependency. and support automatically updating fuzzy timestamps (e.g. "4 minutes ago" or "about 1 day ago"). Download, view the examples, and enjoy.

You opened this page when you opened the page. (This will update automatically. Wait for it.)

Hustcc was born Aug 01, 1989.

Why ?

timeago.js was built to format date with `*** time ago` statement. You can test timeago.js here with the live demo.

Avoid timestamps dated "1 minute ago" even though the page was opened 10 minutes ago; timeago refreshes automatically.
You can take full advantage of page caching in your web applications, because the timestamps aren't calculated on the server.
Very tiny(less than 2kb), and has no dependency, e.g. jQuery.

How ?

First, load and install timeago.js library:

npm install timeago.js

Load timeago.js library file with script tag:

<script src="dist/timeago.js" type="text/javascript"></script>

Or you can use ES6 style:

import * as timeago from 'timeago.js';

Now, let's attach it to your timestamps on DOM ready:

timeago.render(document.querySelectorAll('.need_to_be_rendered'));

This will realtime render all selected(javascript DOM selector) elements with a class of need_to_be_rendered.

<span class="need_to_be_rendered" datetime="2016-07-07T09:24:17Z">July 07, 2016</span>

You can also use it programmatically:

timeago.format(new Date());             //=> ""
timeago.format('2016-09-07', 'zh_CN')           //=> ""
timeago.format(1473245023718);          //=> ""

Locales register ?

Yes, timeago.js has locale/i18n/language support. Here are some configuration examples. Please submit a GitHub pull request for corrections or additional languages.

var locale = function(number, index, totalSec) {
  // number: the time ago / time in number;
  // index: the index of array below;
  // totalSec: total seconds between date to be formatted and today's date;
  return [
    ['just now', 'right now'],
    ['%s seconds ago', 'in %s seconds'],
    ['1 minute ago', 'in 1 minute'],
    ['%s minutes ago', 'in %s minutes'],
    ['1 hour ago', 'in 1 hour'],
    ['%s hours ago', 'in %s hours'],
    ['1 day ago', 'in 1 day'],
    ['%s days ago', 'in %s days'],
    ['1 week ago', 'in 1 week'],
    ['%s weeks ago', 'in %s weeks'],
    ['1 month ago', 'in 1 month'],
    ['%s months ago', 'in %s months'],
    ['1 year ago', 'in 1 year'],
    ['%s years ago', 'in %s years']
  ][index];
};
timeago.register('pt_BR', locale);
// then you can use it
timeago.format(1473245023718, 'pt_BR');
