#angularjs Tutorial for Beginners With #nodejs #ExpressJS and #mongodb #javascript Part I

  • We are going to build a full stack Todo App using the MEAN (MongoDB, ExpressJS, AngularJS and NodeJS).
  • TL; DR: NodeJS has been built from bottom up a non-blocking I/O paradigm, which gives you more efficiency per CPU core than using threads in other languages like Java.
  • But, now you can found it in smartphones, servers, robots, Arduino, RaspberryPi… Thus, it does not matter what technology you use to build web applications, you need to be familiar with Javascript.
  • Programming languages that are blocking (Java, Ruby, Python, PHP, …) overcomes concurrency using many threads of execution while JavaScript handles it using non-blocking event loop in a single thread.
  • These are the changes added to perform the remove functionality:

    Do the same for the details Template

    And also in the details controllers

    When we remove elements from the todos array they also disappear from the DOM.

How To Debug an Angular 1 Application via DevTools

  • I’ll list a few important concepts, but for an in-depth tutorial on debugging JavaScript in the console I highly recommend reading through the DevTools documentation on you might set breakpoints to explore the code and check the value of variables mid-execution.
  • Recently, a friend asked me to help debug their Angular 1 application but I didn’t have immediate access to the source code and the deployed code was minified without source maps.
  • For illustration, here is the same statement executed against the Angular 1 TodoMVC app to list its controllers and providers:

    This snippet has come in handy many times.

  • Unlike providers, controllers are not registered on the application’s  instance.
  • To begin, select an element whose controller you want to inspect:

    Then via the console execute this line:

    Alternatively, you can use  to target an element and use the same code snippet:

    Once you’ve captured a reference to the controller for a particular element, you can inspect the scope and any properties attached to the controller itself and even explore up and down the scope tree to look for shadowed properties and explore child scopes.

The browser provides powerful tools for debugging web applications, including those built with Angular 1. I’ll list a few important concepts, but for an in-depth tutorial on debugging JavaScript in the console I highly recommend reading through the DevTools documentation on developers.google.com.

  • AngularJS (a.k.a. AngularJS 1) is an open-source JavaScript framework.
  • Its goal is to augment browser-based applications with Model–View–Whatever (MV*) capability and reduce the amount of JavaScript needed to make web applications functional.
  • AngularJS (also known as AngularJS 1) is an open-source JavaScript framework for building CRUD-centric Ajax-style web applications.
  • Its goal is to shim the browser to augment the HTML vocabulary with directives useful for building dynamic web applications.
  • AngularJS was developed and is maintained by Google, and is used internally by 1600+ applications.


AngularJS (a.k.a. AngularJS 1) is an open-source JavaScript framework. Its goal is to augment browser-based applications with Model–View–Whatever (MV*) capability and reduce the amount of JavaScript needed to make web applications functional. These types of applications are also frequently known as single-page applications (SPAs). It is entirely distinct from its successor, referred to simply as Angular, with its own tag, see [tag:angular2].

AngularJS V/S Node.js : Compatibility, Applications & Uses

#AngularJS V/S #Nodejs : Compatibility, Applications & Uses 
:- 

#WebApplication #javascript

  • However, understanding the difference in between AngularJS and Node.js is must before you pick any of them for your server side and client side Web Application.
  • However, from last few years, JavaScript emerged largely and it has become a powerful programming language to create optimised server side and client side web applications.
  • Node.js is written in C, C++ and JavaScript languages to interact with server side and create smooth and powerful web applications.
  • In conclusion, Node.js is runtime environment useful to develop server side web applications while AngularJS is useful to develop single page or multi page client side web applications.
  • Node.js is used to build real time server side web applications while AngularJS is more suitable for creating single page client side web applications.

It has always been a confusing part for almost every client to choose in between Angular JS and Node.js for their web applications. In conclusion…
