Overview of this book

If you're writing applications that move structured data from one place to another, this book is for you. This is especially true if you've been using XML to do the job because it's entirely possible that you could do much of the same work with less code and less data overhead in JSON. While the book's chapters make some distinction between the client and server sides of an application, it doesn't matter if you're a frontend, backend, or full-stack developer. The principles behind using JSON apply to both the client and the server, and in fact, developers who understand both sides of the equation generally craft the best applications.

Using REST to search MongoDB


By now, that you might be wondering where JSON comes into play when using MongoDB. When you access a MongoDB database instance using a RESTful interface such as mongo-rest, the documents are transferred to the client using JSON. Let's see how to get a list of documents from MongoDB.

How to do it...

Using REST with Node.js and MongoDB takes several steps.

  1. Be sure you've set up the REST server as we discussed in the introduction. You'll need to have created the files rest-server.js, routes/documents.js, and mongo-rest-example.html with the UI for our RESTful application, and run both the REST server and the document server with Node.js.

  2. Second, be sure that you're running MongoDB.

  3. Next, to process the REST GET request, we need to define the function exports.findAll in documents.js, which should look like this:

    exports.findAll = function(req, res) {
      db.collection('documents', function(err, collection) {
        collection.find().toArray(function(err, items) {
          res...
