import { RouterModule } from '@angular/router';

imports: [
    BrowserModule, RouterModule
],

angular 5 Configuration

// routerConfig.ts

import { Routes } from '@angular/router';
import { CreateComponent } from './components/create/create.component';
import { EditComponent } from './components/edit/edit.component';
import { IndexComponent } from './components/index/index.component';

export const appRoutes: Routes = [
  { path: 'create', 
    component: CreateComponent 
  },
  {
    path: 'edit/:id',
    component: EditComponent
  },
  { path: 'index',
    component: IndexComponent
  }
];

//angular 5 app.module.ts

import { appRoutes } from './routerConfig';

imports: [
    BrowserModule,
    RouterModule.forRoot(appRoutes)
],

Phase 5: Define the Router outlet.

In the app.component.html file, below some the following source code.


<div style="text-align:center">
  <h1>
    Welcome to {{title}}!!
  </h1>
  <nav>
    <a routerLink="create" routerLinkActive="active">Add students</a>
  </nav>
  <router-outlet></router-outlet>
</div>
//Also, we need to change the title attribute.
// app.component.ts

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'Welcome to crypto world';
}

<link rel="stylesheet" href="assets/css/bootstrap.min.css">

and, replace the app.component.html main outlook due to css bootstrap classes.

<nav class="live24u navbar navbar-default">
  <div class="live24u container-fluid">
    <ul class="live24u nav navbar-nav">
      <li class="live24u active">
        <a routerLink="create" routerLinkActive="active">
          Add students
        </a>
      </li>    
    </ul>
  </div>
</nav>

<div class="live24u container">
  <router-outlet></router-outlet>
</div>

Phase 7: Make a form in the create a component file.

First of all, our simple create.component.ts file looks like this.

import { Component, OnInit } from '@angular/core';

@Component({
  selector: 'app-create',
  templateUrl: './create.component.html',
  styleUrls: ['./create.component.css']
})
export class CreateComponent implements OnInit {

  title = 'Add Student';
  constructor() { }

  ngOnInit() {
  }

}

Now I require to create the create.component.html form design.

<div class="panel panel-success">
    <div class="panel-heading">
      {{ title }}
    </div>
    <div class="panel-body">
      <form>
        <div class="stud form-group live24u">
          <label class="col-md-4">Student Name</label>
          <input type="text" class="liveFrm form-control lst" name="student_name"/>
        </div>
        <div class="stud form-group live24u">
          <label class="col-md-4">Student Fees</label>
          <input type="text" class="liveFrm form-control lst" name="studet_price"/>
          </div>
          <div class="stud form-group live24u">
            <button type="submit" class="btn btn-success">Add</button>
          </div>
      </form>
    </div>
  </div>
