Just record the important parts of an HTTP request using your server software, such as Node.js, save them to disk, and replay them on matching subsequent requests when offline mode is enabled. Or use a high level library that already does this; I'm looking into yakbak[0x00]. [0x00] https://github.com/flickr/yakbak

> Except when you want to test edge cases (specific error messages from the server, time outs during response, errors on the network level, etc). Yep, these features are definitely on our roadmap. This is one of the reasons we chose node modules as a tape format: it's just javascript. For example, if you want to add a delay, simply edit your tape and wrap res.end in a setTimeout. Additionally, I want to [make it so tapes format the response according the content-type][1] so that you can easily edit them by hand and have complete control over the response.
