  • Step 2: Create JSON Data File
  • Step 3: Create User Interface
  • Step 4: Create Bootstrap Table
  • Step 5: Update tsconfig JSON
  • Step 6: Start Angular App

Install Angular App

First and foremost, make sure to install the angular cli on your development machine using the given below command.

sudo npm install -g @angular/cli

Next, with the help of the Angular CLI schematic, install the angular application.

ng new ng-demo

Get inside the project folder:

cd ng new ng-demo

Execute command to install the latest version of Bootstrap in angular.

npm install bootstrap --save

Next, add the Bootstrap CSS path in angular.json file to enable the styling.

"styles": [

Create JSON Data File

In this step, you have to create a users.json file; furthermore, you must add the provided json objects to create a json file.

Open and add code in src/app/users.json file.

    "id": 1,
    "name": "Leanne Graham",
    "username": "Bret",
    "email": ""
    "id": 2,
    "name": "Ervin Howell",
    "username": "Antonette",
    "email": ""
    "id": 3,
    "name": "Clementine Bauch",
    "username": "Samantha",
    "email": ""
    "id": 4,
    "name": "Patricia Lebsack",
    "username": "Karianne",
    "email": ""
    "id": 5,
    "name": "Chelsey Dietrich",
    "username": "Kamren",

    "id": 10,
    "name": "Clementina DuBuque",
    "username": "Moriah.Stanton",
    "email": ""

Create User Interface

In the previous step, we created a JSON file, now get into the app.component.ts file, import the UsersJson file and create the USERS interface.

import { Component } from '@angular/core';

import UsersJson from './users.json';
interface USERS {
    id: Number;
    name: String;
    username: String;
    email: String;

  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']

export class AppComponent {
  Users: USERS[] = UsersJson;


Create Bootstrap Table

In this step, you have to use the bootstrap table UI component to display the data from JSON file.

Now, open the app.component.html file, append the entire given code within the angular html file.

<div class="container mt-5">
  <h2>Angular Display Data from Json File Example</h2>
  <table class="table table-striped">
      <tr *ngFor="let user of Users">
        <td>{{ }}</td>
        <td>{{ }}</td>
        <td>{{ user.username }}</td>
        <td>{{ }}</td>

Update tsconfig JSON

Before you start the application, you have to tweak your tsconfig.json file, define the resolveJsonModule and esModuleInterop inside the compilerOptions object.

  "compileOnSave": false,
  "compilerOptions": {
    "resolveJsonModule": true,
    "esModuleInterop": true,  


Start Angular App

Now, you can open the terminal and start writing the given command and hit enter to start the angular app:

ng serve --open

This is the url which you need to view the app.
