Building a Reusable String Input Component in Angular v17

Here in this blog, we will learn about how to build a reusable String Input Component in Angular V17.

Introduction

Angular, a powerful front-end framework, continues to evolve with each version, and in Angular v17, developers have even more tools at their disposal. In this blog post, we’ll explore how to create a reusable string input component in Angular v17. Reusable components not only enhance code maintainability but also improve overall development efficiency.

Setting Up Your Angular Environment

Before diving into the implementation of our reuse string input component, make sure you have Angular v17 installed on your machine. You can use the Angular CLI to quickly scaffold a new project:

ng new my-angular-project
cd my-angular-project

Now, let’s create a new Angular component for our reusable string input:

ng generate component string-input

Creating the Reusable String Input Component

Open the generated `string-input.component.ts` file and define the basic structure of your component:

import { Component, Input } from '@angular/core';
@Component({
  selector: 'app-string-input',
  templateUrl: './string-input.component.html',
  styleUrls: ['./string-input.component.css']
})
export class StringInputComponent {
  @Input() label: string;
  @Input() value: string;
  // Add any other necessary inputs or outputs
}

Now, let’s create the corresponding template in `string-input.component.html`:

html
<div class="string-input">
  <label>{{ label }}</label>
  <input [(ngModel)]="value" />
</div>

This basic structure includes an input field with two-way data binding using Angular’s `ngModel`. The label and value are bound to properties, which will allow us to reuse this component with different labels and initial values.

Styling the Reusable Component

To enhance the visual appeal and ensure consistency across your application, you can add some basic styles in `string-input.component.css`:

css
.string-input {
  display: flex;
  flex-direction: column;
  margin-bottom: 16px;
}

label {
  font-weight: bold;
  margin-bottom: 8px;
}
input {
  padding: 8px;
  border: 1px solid #ccc;
  border-radius: 4px;
}

Integrating the Reusable String Input Component

Now that our reuse string input component is ready, let’s integrate it into another Angular component. Open the template file of any existing component and use the `app-string-input` selector:

html
<app-string-input [label]="'Username'" [value]="user.username"></app-string-input>

Feel free to customize the label and initial value based on your application’s needs.

Conclusion

In this blog post, we’ve covered the process of creating a reuse string input component in Angular v17. Reusable components help maintain a clean and organized codebase, making it easier to develop and maintain Angular applications. As you continue working with Angular v17, explore additional features and improvements to further enhance your development experience.
