Promise shim and functionality extender
Table of contents
What is it?
This library allows to use promises in older browsers as well as add extra functionality to promises that allows promise functionality in the kaleo library set
Installation
This libray can be installed using:
Getting started
The script can be loaded both in the head and in the body. All functionality is automatically loaded as soon as the file is loaded. Note: include this script before any other scripts for proper implementation
<script src="/(node_modules|bower_modules)/peprze/peprze.min.js"></script>
To start using it is as simple as instancing a new promise in the same way as native promises
var test = new Promise(function(resolve, reject){
/* Do async here */
})
Examples
Fetching files
Using Xhr to fetch files using promises
function fetchfile(url) {
var xhr = new XMLHttpRequest();
xhr.open('GET', url, true);
return new Promise(function(resolve, reject){
xhr.onreadystatechange = function() {
if(xhr.readyState === 4) {
if(xhr.status === 200) {
resolve(xhr.responseText);
}
else {
reject(new Error(xhr.status));
}
}
}
xhr.send();
});
}
