Converting Dates with Ractive.js

Is there a way to transform the Epoch time value retrieved from a JSON endpoint into a readable time string format such as "Tue 19 Jan 11:14:07 SGT 2038" without relying on external libraries like moment.js?

var ractive = new Ractive({
  el: '#container',
  template: '#template',
  data: {
    lastUpdated: 2147483647
  }
});
<script src="http://cdn.ractivejs.org/latest/ractive.js"></script>
<pre>$ date --date='@2147483647'
Tue 19 Jan 11:14:07 SGT 2038
</pre>

<div id='container'></div>
<script id='template' type='text/ractive'>
  <h1>Time: {{Date(lastUpdated)}}</h1>
</script>

I am seeking a solution that does not involve using any additional libraries, your assistance is greatly appreciated. Thank you!

Answer №1

When it comes to formatting dates, Ractive remains neutral, allowing users to easily incorporate custom formatters into the data object:

var ractive = new Ractive({
  el: '#container',
  template: '<h1>Time: {{formatDate(lastUpdated)}}</h1>',
  data: {
    lastUpdated: 2147483647,
    formatDate: function ( date ) {
      // insert your formatting logic here...
    }
  }
});

Any changes to lastUpdated will trigger a re-evaluation of the formatter.

To achieve this, utilizing MomentJS is recommended:

var timestamp = 2147483647;
var momentObj = moment(timestamp);
var formattedTime = momentObj.format("LLLL");
var ractiveInstance = new Ractive({
  el: '#container',
  template: '#template',
  data: {
    lastUpdated: formattedTime
  }
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.12.0/locale/af.js"></script>
<script src="http://cdn.ractivejs.org/latest/ractive.js"></script>
<pre>$ date --date='@2147483647'
Tue 19 Jan 11:14:07 SGT 2038
</pre>

<div id='container'></div>
<script id='template' type='text/ractive'>
  <h1>Time: {{lastUpdated}}</h1>
</script>
