Superagent Middleware

app.js

/**
 * Module dependencies
 */
var request = require("superagent");

/**
 * Middleware to sign the request
 */

var authorizeRequest = function(token) {

  // This will be called on the request
  return function authorizeRequest(req, next) {
  
    req.headers.authorization = "Bearer "+token;
    
    // This will be called on the response
    next(null, function (res, nextRes) {
      nextRes();
    });
  }
};

/**
 * Make the request
 */
request
  .get("/api")
  .use(signrequest("this-is-a-secret"))
  .end(function(err, res){
    console.log(res.body)
  });

Awesome! I'll bet that use can be put on plain http, and you could substitute sign request with authorize request, and then it would be generic.

how bout now?

.use(signrequest("this-is-a-secret"))

should have been this right?

.use(authorizeRequest("this-is-a-secret"))

here is the simpler way:

var authorizeRequest = function(token) {

  // This will be called on the request
  return function authorizeRequest(req) {

    req.header.authorization = "Bearer " + token;

    return req;
  }
};
