Create Shake Animation on Invalid Reactive Form Input Fields in Angular 13

Hello friends, welcome back to my blog. Today in this blog post, I am going to tell you, Create Shake Animation on Invalid Reactive Form Input Fields in Angular 13

Here is the tutorial link for update angular version to 13: Update Angular 12 to Angular 13

Guy’s here are the more demos related to Angular 12 with Bootstrap 5:

1. Bootstrap 5 Popover working in Angular 12
2. Bootstrap 5 Tooltip working in Angular 12
3. Bootstrap5 Modal with Forms in Angular 12

Angular 13 came and Bootstrap 5 also and if you are new then you must check below two links:

1. Angular13 Tutorials
2. Angular12 Free Templates
3. Bootstrap 5

Friends now I proceed onwards and here is the working code snippet and please use carefully this to avoid the mistakes:

1. Firstly friends we need fresh angular 13 setup and for this we need to run below commands but if you already have angular 13 setup then you can avoid below commands. Secondly we should also have latest node version installed on our system:

npm install -g @angular/cli 

ng new angulardemo//Create new Angular Project

cd angulardemo// Go inside the Angular Project Folder

2. Now friends, here we need to run below commands into our project terminal to install bootstrap 5 modules  into our angular 13 application:

npm install bootstrap

npm i @popperjs/core

3. Now friends we just need to add below code into src/app/app.component.html file to get final out on the web browser:

 <form [formGroup]="registerForm" (ngSubmit)="onSubmit()">
    <div class="form-group mb-3">
        <input id="inputEmail" type="email" formControlName="email"  [ngClass]="{ 'is-invalid': submitted && f.email.errors }" placeholder="Email address" required="" autofocus="" class="">
        <div *ngIf="submitted && f.email.errors" class="invalid-feedback">
            <div *ngIf="f.email.errors.required">Email is required</div>
            <div *ngIf="f.email.errors.email">Email must be a valid email address</div>
         </div>
    </div>
    <div class="form-group mb-3">
        <input id="inputPassword" type="password" formControlName="password" [ngClass]="{ 'is-invalid': submitted && f.password.errors }" placeholder="Password" required="" class="">
        <div *ngIf="submitted && f.password.errors" class="invalid-feedback">
            <div *ngIf="f.password.errors.required">Password is required</div>
         </div>
    </div>
    <div class="form-group mb-3">
      <button type="submit" class="btn btn-primary text-uppercase mb-2 rounded-pill shadow-sm">Login</button>
   </div>
</form>

4. Now friends we just need to add below code into angular.json file to add bootstrap styles and script:

"styles": [
              ...
              "node_modules/bootstrap/dist/css/bootstrap.min.css"
          ],
"scripts": [
              ...
               "node_modules/bootstrap/dist/js/bootstrap.min.js"
           ]

5. Now friends we just need to add below code into src/app/app.component.css file to add login form validation custom styles:

input {
  height: 50px;
  width: 320px;
  outline: none;
  border: 2px solid #000;
  border-radius: 6px;
  padding: 0px 10px;
  font-size: 13px
}

input.is-invalid {
  border: 2px solid red;
  animation: shake 300ms
}

@keyframes shake {
  25% {
      transform: translateX(4px)
  }

  50% {
      transform: translateX(-4px)
  }

  75% {
      transform: translateX(4px)
  }
}

6. Now friends we just need to add below code into src/app/app.component.ts file to add login form validations:

import { Component} from '@angular/core';
import { FormBuilder, FormGroup, Validators } from '@angular/forms';
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {

  constructor(private formBuilder: FormBuilder) { }
  //Form Validables 
  registerForm:any =  FormGroup;
  submitted = false;

  //Add user form actions
  get f() { return this.registerForm.controls; }
  onSubmit() {
    
    this.submitted = true;
    // stop here if form is invalid
    if (this.registerForm.invalid) {
        return;
    }
    //True if all the fields are filled
    if(this.submitted)
    {
      alert("Great!!");
    }
  
  }


    //login form
  ngOnInit(): void {
    //login form
   //Add User form validations
   this.registerForm = this.formBuilder.group({
    email: ['', [Validators.required, Validators.email]],
    password: ['', [Validators.required]],
    });
  }

}

7. Now friends we just need to add below code into src/app/app.module.ts file to include reactive form module:

...

import { ReactiveFormsModule } from '@angular/forms';

 
...
  imports: [
   ...
    ReactiveFormsModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Friends in the end must run ng serve command into your terminal to run the angular 13 project.

Now we are done friends. If you have any kind of query, suggestion and new requirement then feel free to comment below.

Note: Friends, In this post, I just tell the basic setup and things, you can change the code according to your requirements.
