Import JSON Data in JavaScript Modules

Importing JSON Data:

Write a JavaScript program to import a JSON file as a module and access its properties.

Solution-1: Using import for JSON Files

Code:

File: data.json

This file contains JSON data.

//File: data.json
//This file contains JSON data.

{
  "name": "Monika Nelinho",
  "age": 30,
  "profession": "Developer"
}

File: main.js

This file demonstrates importing and using the JSON data.

//File: main.js
//This file demonstrates importing and using the JSON data.
// Importing JSON data
import data from './data.json';

// Accessing properties from the JSON data
console.log('Name: ${data.name}'); // Logs "Name: John Doe"
console.log('Age: ${data.age}'); // Logs "Age: 30"
console.log('Profession: ${data.profession}'); // Logs "Profession: Developer"

Output:

Name: Monika Nelinho
Age: 30
Profession: Developer

Explanation:

• data.json contains structured JSON data.
• main.js imports the JSON data as a module using import.
• The properties of the imported JSON object (name, age, and profession) are accessed and logged.

Solution-2: Using require for JSON Files (CommonJS)

Code:

File: data.json

//File: data.json
//This file contains JSON data.

{
  "name": "Monika Nelinho",
  "age": 30,
  "profession": "Developer"
}

File: main.js

//File: main.js
//This file demonstrates importing JSON data using require.

// Importing JSON data using require
const data = require('./data.json');

// Accessing properties from the JSON data
console.log('Name: ${data.name}'); // Logs "Name: John Doe"
console.log('Age: ${data.age}'); // Logs "Age: 30"
console.log('Profession: ${data.profession}'); // Logs "Profession: Developer"

Output:

Name: Monika Nelinho
Age: 30
Profession: Developer

Explanation:

• data.json contains structured JSON data.
• main.js imports the JSON data using require (CommonJS syntax).
• The properties of the imported JSON object are accessed and logged.
