RESTful Web API Design with Node.js - Second Edition

Overview of this book

In this era of cloud computing, every data provisioning solution is built in a scalable and fail-safe way. Thus, when building RESTful services, the right choice for the underlying platform is vital. Node.js, with its asynchronous, event-driven architecture, is exactly the right choice to build RESTful APIs. This book will help you enrich your development skills to create scalable, server-side, RESTful applications based on the Node.js platform. Starting with the fundamentals of REST, you will understand why RESTful web services are better data provisioning solution than other technologies. You will start setting up a development environment by installing Node.js, Express.js, and other modules. Next, you will write a simple HTTP request handler and create and test Node.js modules using automated tests and mock objects. You will then have to choose the most appropriate data storage type, having options between a key/value or document data store, and also you will implement automated tests for it. This module will evolve chapter by chapter until it turns into a full-fledged and secure Restful service.

Preface

Authorization


So far, the contacts data service relied on a statically created admin user to access the data. It is time to change that by introducing an API that would provide simple user management capability.

We've already defined AuthUser. Now we will create a module that will take care of creating, updating, and deleting users. The name of the module file will be admin.js, and like the other modules in our application, it will be located in the modules directory:

exports.remove = function (model, _username, response) {
  console.log('Deleting user: '+ _username);
  model.findOne({username: _username}, function(error, 
  data) {
    if (error) {
      console.log(error);
      if (response != null) {
        response.writeHead(500, 
          {'Content-Type' : 'text/plain'});
        response.end('Internal server error');
      }
      return;
    } else {
    if (!data) {
      console.log('User' + _username + ' not...
