1. Install timeago.js

npm install timeago.js

2. import timeago.js

ES6 style is supported, then get global object: timeago.

import timeago from "timeago.js";

// or

var timeago = require("timeago.js");

or link with script in html files:

3. Use class timeago

var timeagoInstance = new timeago();
timeagoInstance.format("2016-06-12");

1. Localization

Default locale is en, and the library supports en and zh_CN.

var timeagoInstance = new timeago();
timeagoInstance.format("2016-06-12", "zh_CN");

You can change the locale in the constructor or use the setLocale method;

var timeagoInstance = new timeago("zh_CN");
// or
new timeago().setLocale("zh_CN");

2. Set relative date

timeago is relative to the current date default. You can set it yourself.

var timeagoInstance = new timeago(null, "2016-06-10 12:12:12"); // set the relative date here.
timeagoInstance.format("2016-06-12", "zh_CN");

3. Use timestamp

new timeago().format(new Date().getTime() - 11 * 1000 * 60 * 60); // will get "11 hours ago"

4. Automatic rendering

HTML code：

js code

var timeagoInstance = new timeago();
// use render to render it in real time
timeagoInstance.render(document.querySelectorAll(".need_to_be_rendered"), "zh_CN");
// or cancel real-time render
timeagoInstance.cancel()

The input API render should be DOM object/array, pure javascript DOM node, and jQuery DOM object supported.

The API cancel will clear all the render timers and release all resources of the instance.

The DOM object should have the attribute datetime or data-timeago with date formated string.

5. Register local language

You can register your own language, this is a class static method. Like below, e.g.

// the local dict example is below.
var test_local_dict = function(number, index) {
  // number: the timeago / timein number;
  // index: the index of array below;
  return [
    ["just now", "a while"],
    ["%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];
};
// register your locale with timeago
timeago.register("test_local", test_local_dict);
// use the locale with timeago instance 
var timeagoInstance = new timeago();
timeagoInstance.format("2016-06-12", "test_local");

You can see locales dir for more locales.

Locale contributions are welcomed, thank you for submitting a GitHub pull request for corrections or additional languages. ^_^~

The website is based on rmm5t/jquery-timeago which is a nice and featured project but depends on jQuery.

locale translations: The library needs more locale translations. You can:

Open an issue to write the locale translations, or submit a pull request. How to ? see en"s translation.

Please test the locale by exec npm test or node tests/locales_test.js. How to write testcase, see en"s test cases.
