Building an Insurance Application in Angular: A Step-by-Step Guide
Building an insurance application can be a game-changer for businesses looking to provide a seamless digital experience for their customers. Angular, a popular frontend framework, offers powerful tools to develop dynamic and scalable applications. When combined with modern UI design practices, such as using Bootstrap, Angular becomes a great choice for developing responsive and user-friendly applications.
In this blog, we'll guide you through the process of building a basic insurance application using Angular, which will allow users to view insurance plans, calculate quotes, and manage policies. We will break down the process into digestible steps, from setting up the project to creating core features of the application.
Step 1: Set Up Your Angular Project
Before we dive into building the actual insurance application, we need to set up our development environment. If you haven’t installed Angular yet, here’s how to do it.
1.1 Install Angular CLI
Angular CLI is the command-line interface that allows you to create and manage Angular projects. Install it globally by running:
npm install -g @angular/cli1.2 Create a New Angular Project
Next, create a new Angular project:
ng new insurance-app
cd insurance-app1.3 Install Bootstrap
To ensure that our application is responsive, we’ll use Bootstrap, a popular CSS framework. Install it with npm:
npm install bootstrapangular.json file:"styles": [
"src/styles.css",
"node_modules/bootstrap/dist/css/bootstrap.min.css"
]Step 2: Design the Application Layout
2.1 Create Key Components
To keep our application organized, we'll create the following components:
- Navbar: For navigation between different pages.
- Home: The main landing page.
- Insurance Plans: A page displaying available insurance plans.
- Quote Calculator: A form for users to get an estimated insurance quote.
Generate these components using Angular CLI:
ng generate component navbar
ng generate component home
ng generate component insurance-plans
ng generate component quote-calculator2.2 Add Navbar for Navigation
In navbar.component.html, add a responsive Bootstrap navbar that will allow users to navigate between the different pages of the application:
<nav class="navbar navbar-expand-lg navbar-dark bg-primary"> <a class="navbar-brand" href="#">InsuranceApp</a> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse navbar-collapse" id="navbarNav"> <ul class="navbar-nav ml-auto"> <li class="nav-item active"> <a class="nav-link" routerLink="/home">Home</a> </li> <li class="nav-item"> <a class="nav-link" routerLink="/insurance-plans">Insurance Plans</a> </li> <li class="nav-item"> <a class="nav-link" routerLink="/quote-calculator">Get a Quote</a> </li> </ul> </div> </nav>
Step 3: Create the Home Page
3.1 Design the Home Page
In home.component.html, create a simple introduction to your insurance application and add a button that takes users to the insurance plans page:
<div class="container mt-4"> <h1>Welcome to InsuranceApp</h1> <p>Your trusted partner for the best insurance plans in the market.</p> <button class="btn btn-primary" routerLink="/insurance-plans">Explore Plans</button> </div>
This page serves as the first screen users will see when they visit the site.
Step 4: Display Insurance Plans
4.1 Create a List of Insurance Plans
In insurance-plans.component.ts, define a few sample insurance plans that users can choose from:
import { Component } from '@angular/core';
@Component({
selector: 'app-insurance-plans',
templateUrl: './insurance-plans.component.html',
styleUrls: ['./insurance-plans.component.css']
})
export class InsurancePlansComponent {
plans = [
{ name: 'Health Insurance', description: 'Comprehensive health coverage for all ages', price: 250 },
{ name: 'Life Insurance', description: 'Secure your family’s future with life insurance', price: 150 },
{ name: 'Car Insurance', description: 'Protect your vehicle with the best coverage', price: 120 }
];
}4.2 Display Plans Using Bootstrap Cards
In insurance-plans.component.html, display these plans using Bootstrap cards for a clean and responsive layout:
<div class="container mt-4"> <h2>Insurance Plans</h2> <div class="row"> <div class="col-md-4" *ngFor="let plan of plans"> <div class="card"> <div class="card-body"> <h5 class="card-title">{{ plan.name }}</h5> <p class="card-text">{{ plan.description }}</p> <p class="card-text"><strong>\${{ plan.price }}</strong></p> <button class="btn btn-primary">Select Plan</button> </div> </div> </div> </div> </div>
Here, we used Bootstrap's grid system to make the cards responsive and easy to read on all screen sizes.
Step 5: Implement Quote Calculator
5.1 Build the Quote Calculation Logic
In the quote-calculator.component.ts, implement a simple quote calculation logic based on the selected insurance type and user’s age:
import { Component } from '@angular/core';
@Component({
selector: 'app-quote-calculator',
templateUrl: './quote-calculator.component.html',
styleUrls: ['./quote-calculator.component.css']
})
export class QuoteCalculatorComponent {
insuranceType: string = '';
age: number = 0;
quoteAmount: number = 0;
calculateQuote() {
if (this.insuranceType === 'Health') {
this.quoteAmount = this.age * 2 + 50;
} else if (this.insuranceType === 'Life') {
this.quoteAmount = this.age * 1.5 + 100;
} else if (this.insuranceType === 'Car') {
this.quoteAmount = this.age * 1.2 + 80;
}
}
}5.2 Create the Quote Calculator Form
In quote-calculator.component.html, create a Bootstrap form for users to input their age and select an insurance type:
<div class="container mt-4"> <h3>Get Your Insurance Quote</h3> <form (ngSubmit)="calculateQuote()"> <div class="form-group"> <label for="insuranceType">Insurance Type</label> <select id="insuranceType" class="form-control" [(ngModel)]="insuranceType" name="insuranceType" required> <option value="Health">Health</option> <option value="Life">Life</option> <option value="Car">Car</option> </select> </div> <div class="form-group"> <label for="age">Your Age</label> <input type="number" id="age" class="form-control" [(ngModel)]="age" name="age" required /> </div> <button type="submit" class="btn btn-primary">Get Quote</button> </form> <div *ngIf="quoteAmount"> <h4>Your Estimated Quote: \${{ quoteAmount }}</h4> </div> </div>
Step 6: Configure Routing
Now, let’s enable navigation between the components by configuring routing in app-routing.module.ts:
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { HomeComponent } from './home/home.component';
import { InsurancePlansComponent } from './insurance-plans/insurance-plans.component';
import { QuoteCalculatorComponent } from './quote-calculator/quote-calculator.component';
const routes: Routes = [
{ path: '', component: HomeComponent },
{ path: 'home', component: HomeComponent },
{ path: 'insurance-plans', component: InsurancePlansComponent },
{ path: 'quote-calculator', component: QuoteCalculatorComponent }
];
@NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule]
})
export class AppRoutingModule { }Conclusion
In this blog, we've walked through how to build a simple yet functional insurance application using Angular. The steps included:
- Setting up a new Angular project and installing Bootstrap.
- Creating key components such as Navbar, Home, Insurance Plans, and Quote Calculator.
- Designing a responsive UI using Bootstrap for a great user experience on all devices.
- Implementing basic quote calculation logic to allow users to get insurance quotes.
By following these steps, you can create a basic insurance application that can easily be extended with more features like policy management, payment integrations, and user authentication. Angular and Bootstrap together provide a powerful combination to build scalable and responsive applications, ideal for industries like insurance.
