Parsing nested JSON using body-parser and express

Set body-parser's extended property to true to allow parsing nested objects.

var express = require('express');var app = express()var bodyParser = require('body-parser');app.use(bodyParser.urlencoded({    extended: true}));

Answering my own question. But, after figuring out how to access the key/value pairs inside the nested JSON object... it became relatively easy to figure out the rest. The updated app.post function now looks like this:

app.post('/update', jsonParser, function (req, res) {    if (!req.body) return res.sendStatus(400);    else {        for(var datapoint in req.body){            //create new instance of LocationCollection document            var point = new LocationsCollection({                X:Number(req.body[datapoint]["x"]),                Y:Number(req.body[datapoint]["y"]),                Orientation:Number(req.body[datapoint]["orientation"]),                Time:req.body[datapoint]["timestamp"],                UserID:req.body[datapoint]["id"]            });            //insert the newly constructed document into the database            point.save(function(err, point){                if(err) return console.error(err);                else console.dir(point);            });        }    }});

I can test if this worked by putting the following method inside the callback function once the mongodb connection is first established:

//Find all location points and print to the console.console.log("Searching for all documents in Location Points Collection");LocationsCollection.find(function(err,data){    if(err) console.error(err);    else console.dir(data);});

This will print any documents that have been previously added to the database. Hopefully this helps.

Try somthing like this.

var app = express();var bodyParser   = require('body-parser');app.use(bodyParser.json({limit:1024*1024, verify: function(req, res, buf){    try {        JSON.parse(buf);    } catch(e) {        res.send({            error: 'BROKEN_JSON'        });    }}}));
