holler.js

144-bytes lightweight JavaScript polling library!

This library can be used to setup a run function in specified intervals that can also be used for polling the server for new data. one of the advantages of this library is to avoid the evil behaviour of setInterval which is a function interval don't wait for the former function to finish before starting which results in bunch of functions that has not been executed.

Use-cases

• AJAX to pull data repeatedly
• Run a function in intervals etc.

API

  holler( func, intervalMs=1000 );

func is the function to run.

intervalMs is the intervals to run func in milliseconds, defaults: 1000.

Example

  holler( function(){
    fetch( 'http://www.awesome-site.com/api/feeds', myOptions )
      .then(function( data ) {
        // Here you get the data to modify as you please
      })
      .catch(function( error ) {
        // If there is any error you will catch them here
      });
  } , 2000 ); // 2000ms = 2 seconds
