cf-api

A pluggable JSON API server

This is CatfishApi but without all of the bloat and a simple API to register plugins. Everything becomes a plugin.

Installation

npm install --save cf-api

Usage

var createApi = require('cf-api')

var api = createApi(options)
  server = api.initialize()

server.get('/', homepage)
server.post('/form', submit)

// This tells the api that you've finished adding your routes
// and you now want it to add the error handling middleware
server.emit('preBoot')

server.listen(port)

API API

var api = createApi(Object: options)

Create an API instance. There are options available:

• checkOrigin - a function with the signature function (url, cb) {} to check req.headers.origin. cb(null, true) to allow and origin, cb(null, false) to deny an origin. Defaults to cb(null, true) for all requests, meaning all cross-domain requests are allowed. It is up to the user to implement their whitelist/blacklist.
• logger - a logger object with methods debug(), info(), warn() and error() (default: console).
• maxBodySize - an option to be passed along to the body-parser json middleware function. If this is a number it will be the number of bytes, otherwise it will be parsed by the bytes module (default: undefined which falls back to the body parser default of '100kB').
• initialMiddleware - an Express middleware function that will be used before all other middleware. Useful for Sentry error handlers.
• corsOptions - an object with the following keys:
  • exposeHeaders - sets Access-Control-Expose-Headers

For backwards compatibility, the allowedDomains option still works and generates a checkOrigin function for you.

api.initialize()

Create and return the server.
