#PromisePipe - reusable promise chains. PromisePipe allows to build a reusable Promise chains. It returns a function which you can call multiple times and each time all chains will be called. The Function returns a promise each time you call it. PromisePipe is built with small core API. It can be extended with custom methods. You can build your domain specific API that describes your business logic. PromisePipe is a singleton. You build chains of business logic and run the code both on server and client. Chains marked to be executed on the server will be executed on the server only and chains marked to be executed in the client will be executed in the client. You need to set methods in PromisePipe to pass messages from the client to the server. And it is up to you what transport to use. check simple todo app. and todo with mongodb and session, live on heroku

The GitHub API provides the best way to get a URL to download an archive. When you make a GET request on that URL, it will redirect you to a URL on codeload.github.com. codeload is the service which provides archives for download and it's on its own domain for caching reasons.

While it's possible to use the codeload URL directly, you generally want to use the API URL, since it handles things like authentication more gracefully, and the codeload URLs for private repositories are generally ephemeral.

an analog of short , file-based process wrapped in a promise all . You could do your encrypt in the 'encrypt' which is wrapped in file handler. encrypt() returns a promise.

segments passes your array of files needing work.

Install PromisePipe

The core API mimics api of Promise. So it should be pretty obvious how to use it. Additionally with data that is returned from previous chain as first argument each function have access to context object. ###pipe : Promise Is a constructed pipe that returns a promise. First argument is a data, second is a context. While data behaves the same way as in Promises context is passing thorough whole chain of promises. ###pipe.then .then adds a simple chain to the pipe. ###pipe.all As in Promises you can compose promise pipes. ###pipe.catch The catch is catching error or reject of previous chains. Behaves as Promise catch. ###pipe.join You can join PromisePipes if you like. ##PromisePipe.use(name, handler) Allows to build your own customized DSL. handler is a function with at least 2 arguments data and context as in simple chain.
