Angular Tutorial: ng add

Welcome to our comprehensive guide on using ng add in Angular! This tutorial is designed for both beginners and intermediates, so let's dive right in. 🎯

What is `ng add`?

ng add is a command used in Angular CLI to add new packages or features to your Angular project. It streamlines the process of adding third-party libraries, Angular modules, and other features. 💡

Why use `ng add`?

Using ng add ensures that the added package is properly configured within your project. It takes care of necessary dependencies, imports, and configurations, saving you time and reducing the risk of errors. 📝

Installing Angular CLI

Before we begin, let's make sure you have Angular CLI installed. If not, you can install it using npm (Node Package Manager) by running:

bash

npm install -g @angular/cli

Creating a new Angular project

Create a new Angular project by running:

bash

ng new my-app

Replace my-app with the name you'd like for your project.

Adding a new package

Let's add a popular package, ngx-bootstrap, to our project. Navigate to your project folder:

bash

cd my-app

Now, use ng add to add ngx-bootstrap:

bash

ng add ngx-bootstrap

This command will install ngx-bootstrap and its dependencies, and update the angular.json file with the necessary configurations.

Using the added package

In this example, we'll use ngx-bootstrap to implement a datepicker. First, import the DatepickerModule in the app.module.ts file:

typescript

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { DatepickerModule } from 'ngx-bootstrap/datepicker';

import { AppComponent } from './app.component';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    DatepickerModule.forRoot()
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Now, you can use the Datepicker component in your template:

html

<datepicker></datepicker>
