3 min read


In today's fast-paced world, staying informed about stock market trends is crucial. In this tutorial, we'll guide you through the process of creating a powerful Stock Market App using Angular, Ionic, and the robust RapidAPI platform. By the end of this journey, you'll have a sleek and feature-rich app that leverages stock market APIs to provide real-time data and insights.


Before we dive into the development process, ensure you have the following prerequisites:

  • Node.js and npm installed

  • Angular CLI installed (npm install -g @angular/cli)

  • Ionic CLI installed (npm install -g @ionic/cli)

  • A RapidAPI account (sign up at

Step 1: Set Up Your Angular Project

Create a new Angular project using the Angular CLI:

ng new stock-market-app
cd stock-market-app

Step 2: Integrate Ionic for a Mobile-Ready Experience

Add Ionic to your Angular project:

ng add @ionic/angular

Step 3: Design Your App Layout

Replace the contents of src/app/app.component.html with a basic layout for your app:

<!-- src/app/app.component.html -->
        Stock Market App

    <!-- Add your stock data display components here -->

Step 4: Connect to RapidAPI

Head over to RapidAPI ( and find a suitable stock market API. Subscribe to the API and obtain the API key.

Step 5: Install HTTP Client for Angular

Install the Angular HTTP client to handle API requests:

npm install @angular/common@latest

Step 6: Fetch Stock Data

Create a service to handle API requests and fetch stock data. Generate a new service using the Angular CLI:

ng generate service stock

Replace the contents of src/app/stock.service.ts with the following:

// src/app/stock.service.ts
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';

  providedIn: 'root'
export class StockService {
  private rapidAPIKey = 'YOUR_RAPIDAPI_KEY';
  private apiUrl = 'YOUR_RAPIDAPI_STOCK_API_URL';

  constructor(private http: HttpClient) { }

  getStockData(symbol: string) {
    const url = `${this.apiUrl}/stock/${symbol}/quote`;
    return this.http.get(url, { headers: { 'X-RapidAPI-Key': this.rapidAPIKey } });

Step 7: Display Stock Data

Update your main component (src/app/app.component.ts) to fetch and display stock data:

// src/app/app.component.ts
import { Component } from '@angular/core';
import { StockService } from './stock.service';

  selector: 'app-root',
  templateUrl: 'app.component.html',
  styleUrls: ['app.component.scss'],
export class AppComponent {
  stockData: any;

  constructor(private stockService: StockService) {}

  getStockData(symbol: string) {
    this.stockService.getStockData(symbol).subscribe((data: any) => {
      this.stockData = data;

Step 8: Update the UI

Modify the UI to display the fetched stock data in src/app/app.component.html:

<!-- src/app/app.component.html -->
        Stock Market App

    <ion-searchbar (ionChange)="getStockData($"></ion-searchbar>

    <ion-card *ngIf="stockData">
        {{ stockData.companyName }}
        Symbol: {{ stockData.symbol }}<br>
        Latest Price: ${{ stockData.latestPrice }}

Step 9: Run Your App

Start your Angular Ionic app:

ionic serve

Visit http://localhost:8100 in your browser to see your Stock Market App in action.
