How to load a JSON file in NodeJS

This is another short, but useful tutorial for beginners. In this post I’m going to show how to load the following JSON dataset with NodeJS:



We don’t have to create an entire project with express to read this file, a simple js file will do.


 var fs = require("fs");
 var jsonAsString = fs.readFileSync("dataset.json");
 var jsonArray = JSON.parse(jsonAsString);
  console.log("Email:", row.first_name);

To load the file we have to provide url to the function readFileSync from fs (File System), it’ll return the content as an string. Before we can use it we just have to convert it to JSON with JSON.parse.

You can execute your code via the command: node node-json.js. If it works it’ll print all the json data on your terminal.
