easy-api-request

Request wrapper providing header and cookie forwarding with express. Will add the request creation function to the 'request' object.

Usage

Configure the wrapper for a specific api

var apiRequest = require('easy-api-request');
apiRequest.create({
	name: 'testAPI',
	config: {
		url: 'http://example.com', // baseUrl for requests
		
		internal: true, //If true then all x- headers are forwarded
		
		jSend: true, //If we are expecting jSend formatted response
		
		headers: [], //Headers we want to proxy from request object
		
		cookies: [], //Cookies we want to proxy from request object
		
		replyCookies: [], //Cookies we want to proxy from reply
		
		opts: {}, //Options for request.defaults
		
		cleanLogData: Function // Gets the opts object before request is made 
		// and should return a cloned/masked object
		// by default masks password and cc names
	}
});

A function will be added to the request object under the specified name, that function takes one boolean parameter, which specifies if the returned request wrapper should return the stream object or not upon request.

Examples of use

// As promise
app.get('/', function (req, res) {
	req.testAPI()
		.get('/cool/path')
		.then(function (resp) {
			res.json(resp);
		})
		.catch(function (err) {
			res.json(err);
		});
});

// With callback
app.get('/', function (req, res) {
req.testAPI().get('/cool/path', function (err, resp) {
  if(err) {
    console.error(err);
  }
  res.json(err || resp);
});

});

// As stream
app.get('/', function (req, res) {
req.testAPI(true).get('/cool/path').pipe(res);

});

// With custom requestOpts 
app.get('/', function (req, res) {

  req.testAPI(false, {
	headers: {
			'x-custom-path': req.path
		}
	})
.get('/cool/path')
.then(function (resp) {
  res.json(resp);
})
.catch(function (err) {
  res.json(err);
});
});
