In this tutorial, I am going to teach you how to read local JSON files in Angular 2 | 7 | 8 application. There are various methods available to read local JSON files in Angular. Let me show you the easiest way to read local JSON files in Offline Angular app.

Let’s create a JSON file, we name it data.json you can name it whatever you want!

Now we’ve created a JSON file with some fake users data. We’ll go to app component file and paste the below code.


import { Component } from '@angular/core';
import sampleData from './data.json';
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
export class AppComponent {
Users: any = sampleData;

Now you’ll see an error in your console, which will say “Consider using ‘–resolveJsonModule’ to import module with ‘.json’ extension”.

To fix this issue we’ll create a file by the name of json-typings.d.ts in your app root folder and paste the given below code in it.

declare module "*.json" {
const value: any;
export default value;

Now your Angular 7 app is ready to serve the data from the local JSON file.

Go to app.component.html and paste the following code in it.

<li *ngFor="let users of Users">
