Readme

LoadJS

LoadJS is a tiny async loader for modern browsers (961 bytes).

Introduction

LoadJS is a tiny async loading library for modern browsers (IE9+). It has a simple yet powerful dependency management system that lets you fetch JavaScript, CSS and image files in parallel and execute code after the dependencies have been met. The recommended way to use LoadJS is to include the minified source code of loadjs.js in your <html> (possibly in the <head> tag) and then use the loadjs global to manage JavaScript dependencies after pageload.

LoadJS is based on the excellent $script library by Dustin Diaz. We kept the behavior of the library the same but we re-wrote the code from scratch to add support for success/error callbacks and to optimize the library for modern browsers. LoadJS is 961 bytes (minified + gzipped).

Here's an example of what you can do with LoadJS:

You can also use more advanced syntax for more options:

The latest version of LoadJS can be found in the dist/ directory in this repository:

https://cdn.rawgit.com/kubetail-org/loadjs/4.3.0/dist/loadjs.js (for development)
https://cdn.rawgit.com/kubetail-org/loadjs/4.3.0/dist/loadjs.min.js (for production)

It's also available from these public CDNs:

UNPKG
- https://unpkg.com/loadjs@4.3.0/dist/loadjs.js (for development)
- https://unpkg.com/loadjs@4.3.0/dist/loadjs.min.js (for production)
CDNJS
- https://cdnjs.cloudflare.com/ajax/libs/loadjs/4.3.0/loadjs.js (for development)
- https://cdnjs.cloudflare.com/ajax/libs/loadjs/4.3.0/loadjs.min.js (for production)

You can also use it as a CJS or AMD module:

$ npm install --save loadjs

var loadjs = require('loadjs');

loadjs(['/path/to/foo.js', '/path/to/bar.js'], 'foobar');

loadjs.ready('foobar', function() {
  /* foo.js &amp; bar.js loaded */
});

Browser Support

IE9+ (async: false support only works in IE10+)
Opera 12+
Safari 5+
Chrome
Firefox
iOS 6+
Android 4.4+

LoadJS also detects script load failures from AdBlock Plus and Ghostery in:

Safari
Chrome

Note: LoadJS treats empty CSS files as load failures in IE9-11 and uses rel="preload" to load CSS files in Edge (to get around lack of support for onerror events on `` tags)

Documentation

Load a single file

loadjs('/path/to/foo.js', function() {
  /* foo.js loaded */
});

Fetch files in parallel and load them asynchronously

loadjs(['/path/to/foo.js', '/path/to/bar.js'], function() {
  /* foo.js and bar.js loaded */
});

Fetch JavaScript, CSS and image files

loadjs(['/path/to/foo.css', '/path/to/bar.png', 'path/to/thunk.js'], function() {
  /* foo.css, bar.png and thunk.js loaded */
});

Force treat file as CSS stylesheet

loadjs(['css!/path/to/cssfile.custom'], function() {
  /* cssfile.custom loaded as stylesheet */
});

Force treat file as image

loadjs(['img!/path/to/image.custom'], function() {
  /* image.custom loaded */
});

Load JavaScript files as modules with non-module fallbacks (in browsers without module support)

loadjs(['module!/path/to/foo.js', 'nomodule!/path/to/bar.js'], function() {
    /* foo.js loaded with type="module" in browsers with module support, skipped silently in browsers without */
    /* bar.js loaded with type="text/javascript" in browsers without module support, skipped silently in browsers with */
});

Add a bundle id

loadjs(['/path/to/foo.js', '/path/to/bar.js'], 'foobar', function() {
  /* foo.js &amp; bar.js loaded */
});

Use .ready() to define bundles and callbacks separately

loadjs(['/path/to/foo.js', '/path/to/bar.js'], 'foobar');

loadjs.ready('foobar', function() {
  /* foo.js &amp; bar.js loaded */
});

Use multiple bundles in .ready() dependency lists

loadjs('/path/to/foo.js', 'foo');
loadjs(['/path/to/bar1.js', '/path/to/bar2.js'], 'bar');

loadjs.ready(['foo', 'bar'], function() {
  /* foo.js &amp; bar1.js &amp; bar2.js loaded */
});

Chain .ready() together

loadjs('/path/to/foo.js', 'foo');
loadjs('/path/to/bar.js', 'bar');

loadjs
  .ready('foo', function() {
    /* foo.js loaded */
  })
  .ready('bar', function() {
    /* bar.js loaded */
  });

Use Promises to register callbacks

loadjs(['/path/to/foo.js', '/path/to/bar.js'], {returnPromise: true})
  .then(function() { /* foo.js &amp; bar.js loaded */ })
  .catch(function(pathsNotFound) { /* at least one didn't load */ });

Check if bundle has already been defined

if (!loadjs.isDefined('foobar')) {
  loadjs(['/path/to/foo.js', '/path/to/bar.js'], 'foobar', function() {
    /* foo.js &amp; bar.js loaded */
  });
}

Fetch files in parallel and load them in series

loadjs(['/path/to/foo.js', '/path/to/bar.js'], {
  success: function() { /* foo.js and bar.js loaded in series */ },
  async: false
});

Add an error callback

loadjs(['/path/to/foo.js', '/path/to/bar.js'], 'foobar', {
  success: function() { /* foo.js &amp; bar.js loaded */ },
  error: function(pathsNotFound) { /* at least one path didn't load */ }
});

Retry files before calling the error callback

loadjs(['/path/to/foo.js', '/path/to/bar.js'], 'foobar', {
  success: function() { /* foo.js &amp; bar.js loaded */ },
  error: function(pathsNotFound) { /* at least one path didn't load */ },
  numRetries: 3
});

// NOTE: Using `numRetries` with `async: false` can cause files to load out-of-sync on retries

Execute a callback before script tags are embedded

loadjs(['/path/to/foo.js', '/path/to/bar.js'], {
  success: function() {},
  error: function(pathsNotFound) {},
  before: function(path, scriptEl) {
    /* called for each script node before being embedded */
    if (path === '/path/to/foo.js') scriptEl.crossOrigin = true;
  }
});

Bypass LoadJS default DOM insertion mechanism (DOM ``)

loadjs(['/path/to/foo.js'], {
  success: function() {},
  error: function(pathsNotFound) {},
  before: function(path, scriptEl) {
    document.body.appendChild(scriptEl);
  
    /* return `false` to bypass default DOM insertion mechanism */
    return false;
  }
});

Use bundle ids in error callback

loadjs('/path/to/foo.js', 'foo');
loadjs('/path/to/bar.js', 'bar');
loadjs(['/path/to/thunkor.js', '/path/to/thunky.js'], 'thunk');

// wait for multiple depdendencies
loadjs.ready(['foo', 'bar', 'thunk'], {
  success: function() {
    // foo.js &amp; bar.js &amp; thunkor.js &amp; thunky.js loaded
  },
  error: function(depsNotFound) {
    if (depsNotFound.indexOf('foo') &gt; -1) {};  // foo failed
    if (depsNotFound.indexOf('bar') &gt; -1) {};  // bar failed
    if (depsNotFound.indexOf('thunk') &gt; -1) {};  // thunk failed
  }
});

Use .done() for more control

loadjs.ready(['dependency1', 'dependency2'], function() {
  /* run code after dependencies have been met */
});

function fn1() {
  loadjs.done('dependency1');
}

function fn2() {
  loadjs.done('dependency2');
}

Reset dependency trackers
```
loadjs.reset();
```

Implement a require-like dependency manager

var bundles = {
  'bundleA': ['/file1.js', '/file2.js'],
  'bundleB': ['/file3.js', '/file4.js']
};

function require(bundleIds, callbackFn) {
  bundleIds.forEach(function(bundleId) {
    if (!loadjs.isDefined(bundleId)) loadjs(bundles[bundleId], bundleId);
  });
  loadjs.ready(bundleIds, callbackFn);
}

require(['bundleA'], function() { /* bundleA loaded */ });
require(['bundleB'], function() { /* bundleB loaded */ });
require(['bundleA', 'bundleB'], function() { /* bundleA and bundleB loaded */ });
