  2. Creation of First angular project

  6. Create services for http call, error handling etc.
  7. Registration and login with JWT toke
  8. decode token and get data from token                                       

I believe the good way to learn anything new is to do more practical instead of theory . So after a short description will go straight for practical.

Lets see what is angular and why to use : Angular is a JavaScript based application design development framework for creating SPA(single page applications). Its a framework means it provides us all the required elements which are needed to develop a SPA. To understand more details kindly follow the https://angular.io/docs .

Preparation of environment : In order to start angular development we need to install some software as below :

  1. Node.js: can be installed latest version from https://nodejs.org/en/

  2. npm pacakge :  run npm -v in a terminal window :


3. Install vs code :https://code.visualstudio.com/download download window version and install in your pc.

4. Angular cli: angular cli creates your angular project , generate application and library code, and perform a variety of ongoing development tasks such as testing, bundling, and deployment . to install it type below command and hit enter :

npm install -g @angular/cli , this command can be run through vs terminal also . that will see later .After running this command latest angular cli will be installed in your pc , so for any application you no need to install seperately. If you want to install specific version kindly run the command :

1
npm install -g @angular/cli@versionthatyouwant

So , here we have all the required software to start development.

Lets create our first default angular project using vs code:

  1. open vs code – go to terminal ->new terminal and type below command in your folder location : ng new angular-tutorial (angular-tutorial is my project name) and hit enter . In the below screen shot I have created my project in d drive .

Once I hit enter I can see below option to select , for routing I will enter yes and enter then it asks me to choose stylesheet ,you can choose css/scss . since I am going to use css so I will choose css and press enter.

You can see something like below screen while creating new project :

Once project created go to file->open folder ->browse your newly created project and click on select folder . your project will be opened in vs code workspace.

To run this project : go to terminal->new terminal->type ng serve

If you want to build first then type ng build then ng serve . ng serve will build then run the application. after building you will see below url to browse your app.

Here you are ready to browse your first default angular app . open google chrome /browser and type http://localhost:4200 and you will see your app is running.

Here we have completed our lesson to setup and create first default project . In next lesson we will learn how to change and customize pages .

Create Reactive form in angular

Image
  In angular we can create two types of forms 1. Reactive form 2.template based form In Reactive form  : all the codes handle in type script , no need to use ngModel to get and set value in control. we define form and formcontrolname for each control , and through formControl we get and set value .reactive form code is neat and clean when we have more complex structure or validation we should use reactive form . Template driven  : data binding is done via ngModel ,generally we can use this approach for simple form ,in this approach code became messy and very difficult to manage . Also in this approach difficult to handle all validation ,need more coding. So , I like to go with Reactive form approach instead of Template based. In our tutorial all forms will be reactive , but we can use both approach if required. I am going to create employee form which will have below fields : Employee Id ,Employee Name, email Id,Mobile Number,Password etc.. our final output will be a...
