HTML5 cache-manifest compilation for broccoli
A nice introduction on the subject: http://www.html5rocks.com/en/tutorials/appcache/beginner/
There's also a Wicked-Good-Ember talk on this subject, see http://confreaks.tv/videos/wickedgoodember2015-taking-ember-offline
npm install --save-dev broccoli-manifest
npm install --save broccoli-merge-trees
//app/config/environment.js
ENV.manifest = {
enabled: true,
appcacheFile: "/manifest.appcache",
excludePaths: ['index.html', 'someother.html'],
includePaths: ['/'],
network: ['api/'],
showCreateDate: true
}Upgrade your index.html (see below) and you are done.
npm install --save broccoli-manifest
Use broccoli-manifest as your last filter in the Brocfile.js like this
var writeManifest = require('broccoli-manifest');
...
var completeTree = mergeTrees([appJs, appCss, publicFiles]);
module.exports = mergeTrees([completeTree, writeManifest(completeTree)]);You can pass some options as the second argument to writeManifest:
writeManifest(completeTree, {
appcacheFile: '/manifest.appcache', // Name of the generated appcache file - default value shown
fallback: ['assets/is-online.json assets/offline.json'] // Lines to add to the FALLBACK section of the generated manifest
});showCreateDate toggles the inclusion of a Date object or a random string in your manifest. If you
want to hide the build date from customers, this is your setting.
Thanks to #9 files can be filtered using regular expressions:
{
excludePaths: ['index.html', new RegExp(/.\.map$/)],
includePaths: ['']
}var mergeTrees = require('broccoli-merge-trees');
var manifest = require('broccoli-manifest');
...
all app.import statements go here
...
// Write a html5 manifest.appcache file with jquery external
var completeTree = app.toTree();
var manifestTree = manifest(completeTree)
manifestTree.includePaths(["https://code.jquery.com/jquery-2.1.1.min.js"])
module.exports = mergeTrees([completeTree, manifestTree]);Add manifest="manifest.appcache" to your <html> tag. The extra <script> tag
adds an eventlistener which automatically refreshes your page after a cache update.
Another approach is using this gist https://gist.github.com/ef4/82f37eb5dae4e56467b6 which loads all files stated in the manifest file.
<!DOCTYPE html>
<html manifest="manifest.appcache">
<head>
<script type='text/javascript'>window.addEventListener('load',function(e){window.applicationCache.addEventListener('updateready',function(e){if (window.applicationCache.status==window.applicationCache.UPDATEREADY){window.applicationCache.swapCache();window.location.reload();}},false);},false);</script>
