Reading a JSON File in Node.js

To read a JSON file in Node.js, you can use the built-in fs (file system) module as you would to read any text file and then use the JSON.parse() method to parse the file's contents into a JavaScript object. In this Node.js Read JSON File Example, we read a JSON file into a memory string using the fs.readFile() method. Click Execute to run the Node.js Read JSON File Example online and see the result.
