EightTrack

Cache HTTP requests in the Meteor framework. Based on the popular VCR package for other frameworks, such as Rails. This typically is used in testing code that involves outgoing http requests for APIs and such. By caching, the chance of maxing out requests is drastically reduced. Plus, it is more considerate to your API providers, as well :).

Installation

meteor add drewmoore:eight-track

• It is recommended that you add eight-track-cassettes/ to your project's .gitignore.

Usage

In any server-only code (for the time being), wrap an http response in the following manner:

EightTrack.useCassette('myCachedResponse', function () {
  result = HTTP.get('https://jsonplaceholder.typicode.com/posts/1');
});

• This will first find or create a directory in the project root called eight-track-cassettes/.
• This will then find or create a file named myCachedResponse.json in the directory.
• If the file does not exist or it is determined to be expired (see below), myCachedResponse.json will store a replica of the http response.
• If the file exists and is not expired, the json file will be parsed and the original http response simulated, complete with headers and all.

Cache Expiration

Currently, all cassettes are set to expire 24 hours after creation, according to EightTrack's reRecordInterval. In the near future, I plan on allowing this to be customized through a config file.

Client-Side Caching

This is currently a wish list feature.
