Angular Bootstrap 5 Popup Registration Form

In this article, I am going to implement step-by-step bootstrap5 popup registration form. and The registration form will be built with Angular reactive form module.

Generate new angular project

ng new bootstrap-popup

cd bootstrap-popup

Integrate bootstrap in this project

Install bootstrap package

npm i bootstrap

Add bootstrap files

Bootstrap “node_modules/bootstrap/scss/bootstrap.scss” and “node_modules/bootstrap/dist/js/bootstrap.min.js” files add in styles and scripts section of src/angular.json file.

      "architect": {
        "build": {
          ...
          "options": {
            ...
            "styles": [
              "node_modules/bootstrap/scss/bootstrap.scss",
              "src/styles.scss"
            ],
            "scripts": [
              "node_modules/bootstrap/dist/js/bootstrap.min.js"
            ]
          },
        ...
      }

Add Reactive form module

Edit src/app/app.module.ts

import { NgModule } from '@angular/core';
import { ReactiveFormsModule } from '@angular/forms';
import { BrowserModule } from '@angular/platform-browser';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    ReactiveFormsModule,
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Let’s build Reactive Registration form

edit src/app/app.compontent.ts file, and build reactive form

import { Component, OnInit } from '@angular/core';
import { FormBuilder, FormGroup, Validators } from '@angular/forms';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent implements OnInit {
  registerForm: FormGroup = this.fb.group({
    firstName: ['', [Validators.required]],
    lastName: ['', [Validators.required]],
    email: ['', [Validators.required, Validators.email]],
    number: ['', [Validators.required, Validators.minLength(10)]],
    password: ['', [Validators.required, Validators.minLength(8)]],
    password1: ['', [Validators.required, Validators.minLength(8)]]
  });

  constructor( private fb: FormBuilder) { }

  ngOnInit(): void {}
  
  
  get firstName(): any {
    return this.registerForm.get('firstName');
  }
  get lastName(): any {
    return this.registerForm.get('lastName');
  }
  get email(): any {
    return this.registerForm.get('email');
  }
  get number(): any {
    return this.registerForm.get('number');
  }
  get password(): any {
    return this.registerForm.get('password');
  }
  get password1(): any {
    return this.registerForm.get('password1');
  }

  registerFormSubmit(): void {
    const formData = this.registerForm.value;
    delete formData.password1;
    console.log(formData);
    // Api Request Here
  }
}

Add bootstrap modal and form to html

edit src/app/app.component.html, and add following code.

<nav class="navbar navbar-expand-lg navbar-light bg-light py-4">
  <div class="container">
    <a class="navbar-brand" href="#">Navbar</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent"
      aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarSupportedContent">
      <ul class="navbar-nav me-auto ps-5 mb-2 mb-lg-0">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Link</a>
        </li>
        <li class="nav-item dropdown">
          <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-bs-toggle="dropdown"
            aria-expanded="false">
            Dropdown
          </a>
          <ul class="dropdown-menu" aria-labelledby="navbarDropdown">
            <li><a class="dropdown-item" href="#">Action</a></li>
            <li><a class="dropdown-item" href="#">Another action</a></li>
            <li>
              <hr class="dropdown-divider">
            </li>
            <li><a class="dropdown-item" href="#">Something else here</a></li>
          </ul>
        </li>
        <li class="nav-item">
          <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
        </li>
      </ul>
