Tools that read through a directory, stream or tree and create an Application Cache manifest for you.

AppCache is still a douche but luckily there are tools available to take the pain out of generating your initial manifest files:

• Grunt: grunt-manifest is currently the de facto option, but the project lead is looking for a new maintainer. In light of that grunt-appcache is an alternative in case you're looking for more active support.
• Gulp: gulp-manifest is inspired by grunt-manifest and has a similar set of options.
• Broccoli: broccoli-manifest brings manifest file compilation based on trees.

This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.

You're Missing the Point of Promises

Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:

getTweetsFor("domenic", function (err, results) {
 // the rest of your code goes here.
