reddit-mobile

reddit-mobile is a web server and build system for building polymorphic React applications in node or io.js. It is part of a larger series of plugins that, together, form frontend applications for reddit.

A Brief Overview

This application provides the core to set up an Express web server and html5 history api, and have these send a request object (containing path, data, etc) and a callback (a promise interface) to the App.

This application also provides a build system and a base css framework, shared across plugins.

                |
                v
            +--------+
            | plugin | -> cb.resolve({ body: reactElement })
            |        | -> cb.reject({ status: 401 })
            +--------+ 

The App has an instance of an Express-like request router that it uses to map requests to the appropriate handling function, and is run on both the client- and server- side. The React lifecycle can be used to control client-specific code.

Plugins register themselves via two interfaces:

1. Route handlers that take two paramaters, req and res. res is a promise interface that should be called using res.resolve({ body: reactElement, status: 200}) or res.reject({ body: error, status: 400}). (Body and status are optional in both cases, but should generally be added.) A complete example of route handling can be seen at routes.jsx.
2. Mutators that modify the rendering of react components. An element query syntax is provided, documentation forthcoming.

Getting Up and Running

0. Install node.js v0.12+ or io.js v1.8.1+.
1. Fork and clone this project.
2. Run npm install to install other dependencies.
3. Run git submodule update --init to download this project's submodules.
4. Run npm run build to build the assets (npm run watch to set up a filesystem watcher.)
5. Register a new oauth application and set up your environment variables
6. Run npm start to start the web server. Optionally, create a startup script at start.sh that sets environment variables and starts the server; start.sh has been added to the .gitignore and will not get checked in.
