Mongoose GeoJSON schema example

map-item.js

const mapItemSchema = new mongoose.Schema({
    name: String,
    location: {
        // It's important to define type within type field, because
        // mongoose use "type" to identify field's object type.
        type: {type: String, default: 'Point'},
        // Default value is needed. Mongoose pass an empty array to
        // array type by default, but it will fail MongoDB's pre-save
        // validation.
        coordinates: {type: [Number], default: [0, 0]}
    }
});
const MapItem = mongoose.model('MapItem', mapItemSchema);


MapItem.create({
    name: 'Toronto',
    location: {
        type: 'Point',
        // Place longitude first, then latitude
        coordinate: [-79.3968307, 43.6656976]
    }
});

having a default to 0 0 is not a good idea

having a default to 0 0 is not a good idea

why ?

I believe that's because it is a valid location, hence when if there is a missing value it will default to resolve to 0,0 coordinates.

It's a non usable location. If you have Toronto POIS you could use Toronto Center instead, maybe.
