Wrapped in module.exports so you can use it via browserify.
In your package json, include:
devDependencies: {
"apps-resource-loader": "git+https://github.com/pascalopitz/apps-resource-loader.git"
}
In your file, you can now do this:
var RAL = require('apps-resource-loader')
Other changes:
RAL.Queue.skipOnError(boolean);
RAL.Debugger.activate();
RAL.Debugger.deactivate();
RAL.Debugger.log(...);
To build the libary into a minified file:
npm run-script compile
This will create lib/ral.min.js
You can request external images using XMLHttpRequest and transform them into ObjectURLs. Then set the src attribute in the <img>
tag to each ObjectURL and it should work.
Since this is a very common use case, we created this library to simplify it. Just drop the apps-resource-loader ral.min.js to your project and then:
var remoteImage,
container = document.querySelector('.imageContainer'),
toLoad = { 'images': [
'http://myserver.com/image1.png',
'http://myserver.com/image2.png' ] }; // list of image URLs
toLoad.images.forEach(function(imageToLoad) {
remoteImage = new RAL.RemoteImage(imageToLoad);
container.appendChild(remoteImage.element);
RAL.Queue.add(remoteImage);
});
RAL.Queue.setMaxConnections(4);
RAL.Queue.start();
Remember that you need permission in the manifest.json
to all domains you will be XHR'ing to. If you don't know beforehand where those images will be hosted, you can ask permission for any url:
permissions: ['<all_urls>'],
