how to insert a .json document to mongo server by mongojs in node

Question

I'm new with nodeJS and MongoDB. I have this code:

var fs = require('fs');
var mongojs = require('mongojs');
var db = mongojs('monitor', ["configurations"]);

fs.readFile('json/object1.json', 'utf8', function (err, data) {
    if (err) throw err;
    console.log(data);

    db.configurations.insert(data, function(err, doc) {
        console.log(data);
    if(err) throw err;
  });
});

no data insered to the mongodb, and I've got no error. the both console.log(data) print the json string as well.

Solution

Try to parse it as JSON before inserting it into the document

fs.readFile('json/object1.json', 'utf8', function (err, data) {
    if (err) throw err;
    console.log(data);
    var json = JSON.parse(data);

    db.configurations.insert(json, function(err, doc) {
        console.log(data);
        if(err) throw err;
    });
});
