JavaScript: Write a JSON object to a file

JavaScript fundamental (ES6 Syntax): Exercise-251 with Solution

Write a JavaScript program to write a JSON object to a file.

• Use fs.writeFileSync(), template literals and JSON.stringify() to write a json object to a .json file.

Sample Solution:

JavaScript Code:

//#Source https://bit.ly/2neWfJ2 
// Import the 'fs' module to work with the file system
const fs = require('fs');

// Define a function 'JSONToFile' that writes a JSON object to a file
const JSONToFile = (obj, filename) =>
  // Write the JSON object to a file with the provided filename and '.json' extension
  fs.writeFile(`${filename}.json`, JSON.stringify(obj, null, 2));

// Call 'JSONToFile' with a sample JSON object and filename
JSONToFile({ test: 'is passed' }, 'testJsonFile'); // writes the object to 'testJsonFile.json'
