Environment Setup
In this chapter, you will learn in detail about setting up the working environment of ngx-bootstrap on your local computer. As ngx-bootstrap is primarily for angular projects, make sure you have Node.js and npm and angular installed on your system.
Create an angular project
First, create an angular project to test ngx-bootstrap components using the following commands.
ng new ngxbootstrap
It will create an angular project named ng bootstrap.
Add ngx-bootstrap as dependency
You can use the following command to install ngx-bootstrap in the newly created project−
npm install ngx-bootstrap
You can observe the following output once ngx-bootstrap is successfully installed −
+ [email protected] added 1 package from 1 contributor and audited 1454 packages in 16.743s
Now, to test if bootstrap works fine with Node.js, create the test component using the following command −
ng g component test CREATE src/app/test/test.component.html (19 bytes) CREATE src/app/test/test.component.spec.ts (614 bytes) CREATE src/app/test/test.component.ts (267 bytes) CREATE src/app/test/test.component.css (0 bytes) UPDATE src/app/app.module.ts (388 bytes)
Clear content of app.component.html and update it following contents.
app.component.html
<app-test></app-test>
Update content of app.module.ts to include the ngx-bootstrap accordion module. We’ll add another module in subsequent chapters. Update it following contents.
app.module.ts
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { AppComponent } from './app.component';
import { TestComponent } from './test/test.component';
import { AccordionModule } from 'ngx-bootstrap/accordion'
@NgModule({
declarations: [
AppComponent,
TestComponent
],
imports: [
BrowserAnimationsModule,
BrowserModule,
AccordionModule.forRoot()
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
Update content of index.html to include bootstrap.css. Update it following contents.
index.html
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Ngxbootstrap</title>
<base href="/">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="icon" type="image/x-icon" href="favicon.ico">
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<app-root></app-root>
</body>
</html>
In the next chapter, we’ll update the test component to use ngx-bootstrap components.
