NodeJs JSON.parse - SyntaxError: Unexpected token u in JSON at position 0

Essentially all I am trying to do is simply parse my JSON file using this code:

var fileName = `./tasks/file-1.json`

fs.readFile(fileName, function(err, data){

    var parsedData = JSON.parse(data);
    console.log(`Entered ${parsedData.fname}`);

});

My file-1.json file looks like this:

{
  "fname": "Test"
}

So for whatever reason the console should log "Entered Test", however it is throwing me the error:

SyntaxError: Unexpected token u in JSON at position 0

I have checked over everything and I'm unsure of where to go from here.

Any help is appreciated!

Check whether the JSON file exists in the same path you provided.

This one is working bro!

const fs = require('fs')
const fileName = './tasks/file-1.json'

fs.readFile(fileName, function(err, data){
    var parsedData = JSON.parse(data);
    console.log(`Entered: ${parsedData.fname}`);
});

Check the encoding of your file.

also try 

fs.readFile(fileName, 'utf8', function(err, data){

    var parsedData = JSON.parse(data);
    console.log(`Entered ${parsedData.fname}`);

});

Hello I created a simple example. File name must be the exact driectory and your JSON file should not include ;

You can use __dirname gives you the current directory path and path.join combines the given string parameters to understanble path.

Hope this help.

// index.js
const fs = require('fs');
const path= require('path');

const file = fs.readFileSync(path.join(__dirname, 'test.json'));
console.log(JSON.parse(file.toString()).key);

// test.json
{
    "key": "1"
}
