Read .json file line by line

I have a json file with json objects in it, please how can I read the json objects line by line. Is this the best way to read a json file using node.js, pardon my question, just a node.js newbie

My json file simply contains lines of json objects as:

file.json
{"name":"user1"},
{"name":"user2"},
{"name":"user3"}

and I am trying to read the file with

app.get('/s',function(req,res){
  var fs = require('fs');
var file = __dirname + '/file.json';


    fs.readFile(file, 'utf8', function (err, data) {
      if (err) {
        console.log('Error: ' + err);
        return;
      }

      data = JSON.parse(data);

      console.dir(data);
    });
    });

I get an error with that code that says "unexpected token {" just on the second line", tanks

//EDIT It turned out my Json file was invalid because readFile reads the entire file, I changed it by putting the objects in an array:

file.json
[
{"name":"user1"},
{"name":"user2"},
{"name":"user3"}
]

Then this code reads the entire file (array)

var fs = require('fs');
var file = __dirname + '/file.json';

fs.readFile(file, 'utf8', function (err, data) {
  if (err) {
    console.log('Error: ' + err);
    return;
  }

  data = JSON.parse(data);

  data.forEach(function(user){ 
    console.log(user.name);
  })

});
