Introduction to using ExpressJS with MongooseJS and NodeJS - Part 2

This is a continuation of my previous blog on using express on NodeJS and MongooseJS. Please refer to that tutorial before continuing further in this tutorial.

Here we gonna continue our previous applications CRUD functionalities, but first we gonna streamline our project by using nodemon package.
  • Intializing Nodemon using following command,
    • npm install nodemon --save-dev
  • Here, Nodemon restarts the server automatically each time you save a file that the server uses.
  • The reason for using it as only as a developing dependency is we only need it in development time.
  • There are many ways to run the application using nodemon, but i will use a much simpler way,
  • Here we gonna define nodemon in run script in package.json
  • Now we need to enter the following command in terminal inorder to run the application,
    • npm run dev
  • So we are back to our main topic CRUD functionalities. We have already created GET-READ capability in previous tutorial.
  • Let's start on POST-CREATE capability,
  • This POST request can be triggered either with JS or thorugh a <form> element.
  • First lest's create a form in index.html which can trigger a POST request.
  • On our server, we can handle this POST request with a post method that Express provides. It takes the same arguments as the GET method,
  • Now when nodemon restarts the server,go to localhost:3000 and fill the form and click submit button.
  • You will be able to see this output in the terminal.
  • Now,we need to get the input values from the form,since Express doesn't handle reading data from form element on it's own, need to add another package called body-parser.

    The rest of the tutorial will be updated soon !!! Sorry for the inconvenience ,you can check out the full code Here

Node.js is a platform built on Chrome's JavaScript runtime for easily building fast and scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices. [TutorialsPoint] Here's a few key point regarding NodeJS, Developed by Ryan Dahl.   Created with the aim of creating real-time websites with push capabilities (websockets). NodeJS is an open source, cross platform runtime environment for server-side and networking applications. Build on V8 engine, Chrome’s JavaScript engine. Uses event-driven, non-blocking I/O model which makes NodeJS lightweight and efficient. Ideal for data-intensive real-time applications that run across distributed devices. NodeJS comes with several JavaScript libraries that help basic programming. NodeJS eco-system ‘npm’ is the largest in the world for open source libraries.   Let's...

Using OAuth 2.0 Framework to Manipulate Files in Google Drive

Let's see why OAuth is important? OAuth is a specification that allows users to delegate access to their data without sharing their username and password with that service. That's cool. But why do you care, as a developer? There's a lot of information and a lot of uses that OAuth provides, that you wouldn't normally get without it, which include things like social graphs of your users, sharing information via your users, things like tweeting and posting to Facebook. You can aggregate user data in order to find interests, etc. about your users. In our day to day interactions on internet, we come across with lots of websites where we have to create accounts to use the website for our work.  If you use different credentials for different accounts, it becomes worse where you have to remember all your usernames and passwords for each website. In order to address this issue, modern websites make use of the OAuth protocol with the concepts of “Identity Federation” and “Del...
