How to add GeoJson data with mongoose? - node.js

Question

I am sending the object to create a user model.
"{
type: 'Point',
coordinates: [ 25.2239771, 51.4993224 ]
}"
And, here is the Mongoose Schema that I created.
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const UserProfileSchema = new Schema(
{
userId: {
type: String,
// required: true,
unique: true,
},
userFirstName: {
type: String,
// required: true,
},
userLastName: {
type: String,
// required: true,
},
userGender: {
type: String,
// required: true,
},
userCoordinates: {
type: {
type: String,
default: 'Point',
},
coordinates: {
type: [Number],
index: '2dsphere',
},
},
},
{ collection: 'userprofilemodels' }
);
module.exports = UserProfile = mongoose.model(
'userprofilemodels',
UserProfileSchema
);
This is the code that I am using to add geoJson type file. However, I am getting an error.
I also tried to add index after the Schema has been defined
await new userProfileModel({
userId,
userFirstName,
userLastName,
userCoordinates,
})
.save()
.then(() => {
console.log('it worked!');
res.send('worked!');
})
.catch((error) => {
console.log('did not worl')
// console.log(error);
});
If I exclude userCoordinates, then it works. So, def my geoJson object is wrong. However, I have no clue where I have made mistakes.

Answer 1

Mongoose supports GeoJSON objects indexing so first add the "2dsphere" index to the userCoordintes rather than to the coordinates within the object in order to make it work.
userCoordinates: {
type: {
type: String,
default: 'Point',
},
coordinates: {
type: [Number],
default: undefined,
required: true
},
index: '2dsphere'
},
Make sure your userCoordinates looks something like this:
const userCoordinates = {
type: "Point",
coordinates: [coordinatesA, coordinatesB],
};

Taken from the mongoose documentation it seems the GeoJSON Type mustn't be only a String.
here is the example with location as a GeoJSON type:
const citySchema = new mongoose.Schema({
name: String,
location: {
type: {
type: String, // Don't do `{ location: { type: String } }`
enum: ['Point'], // 'location.type' must be 'Point'
required: true
},
coordinates: {
type: [Number],
required: true
}
}
});
