Mongoose Schema for geoJson coordinates

I tried to create a schema for geojson but have had some problems with syntax for coordinates.

Here's my current code:

var DataSchema = new Schema({
properties: {
title: { type: String, required: true },
description: { type: String, required: true },
date: { type:Date, default:Date.now }
},
geometry: {
coordinates: []
}
});


I tried using
[]
(empty array), it creates
''
and
[Number,Number]
but it doesn't work.

My question is: how do I have to construct my schema so as result I will get

coordinates: [ 3.43434343, 5.543434343 ]


without quotation marks, is this possible?

Express Route

app.post('/mountain_rescue', function (req, res){

new rescueData({properties:{title: req.body.title, description: req.body.description},geometry:{
coordinates:req.body.coordinates}}).save(function (e, result) {
console.log(result);
});
res.redirect('/mountain_rescue');
});


View

<div id="AddingPanel">
<form method="post" action="mountain_rescue" >
Title:<input type="text" name="title">
Description:<textarea type="text" name="description"></textarea>
Coordinates:<input type="text" name="coordinates">
<button type="submit">Add</button>
</form>



Answer

Like this;

var DataSchema = new Schema({
  properties: {
    title:       { type: String, required: true },
    description: { type: String, required: true },
    date:        { type:Date, default:Date.now }
  },
  geometry: {
    coordinates: { type: [Number], index: '2dsphere'}
  }
});

Here is your update route handler, it converts coordinates string to number array;

app.post('/mountain_rescue',  function (req, res) {
  new rescueData({
    properties: {
      title: req.body.title, description: req.body.description
    },
    geometry: {
      coordinates:req.body.coordinates.split(',').map(Number)
    }
  }).save(function (e, result) {
    console.log(result);
  });
  res.redirect('/mountain_rescue');
});
