How to provide your app with a network API

I am going to write a Ruby application that implements a video conversion workflow consisting of multiple audio and video encoding/processing steps.

The application interface has two core features:

• queueing new videos
• monitoring the progress for each video

The u开发者_运维百科ser can access these features using a website written in Ruby on Rails.

The challenge is this: I want make the workflow app a self-sufficient application, not dependent on the existence of the web view.

To enable this separation I think that adding a network API to the workflow application is a good solution because this allows the workflow app to reside on a different server than the web server.

My question is: Which solution do you suggest for such a network API?

A few options are:

• implement a simple TCP server and invent my own string based API
• use some sort of REST api (I don't know if this is appropriate for this situation)
• some sort of web-services solution (SOAP, XML-RPC)
• another existing framework

Feel free to share your thoughts on this.

I would suggest two things:

• First, use REST as your API. This allows you to write one core application with both a user interface and an API for outside applications to use.

• Second, take a look at PandaStream. It's a Merb application that encodes videos from multiple formats into flash. It has a REST API, and there's even a Rails plugin so you can integrate it with your application. It might be a good example codebase, or even a replacement for the one you're trying to build.

Hope my answer helped,
