Question

Using Sequelize and geospatial queries, if I want to find the \"n\" closest points to a certain location, how should the Sequelize query be?

Assume I have a model th

Answer 1

Building off @Edudjr's answer, this is what I did to get it to work in my project:

const location = sequelize.literal(`ST_GeomFromText('POINT(${ startLongitude } ${  startLatitude })')`)
const distance = sequelize.fn('ST_Distance_Sphere', sequelize.col('location'), location)

const inRadius = await Position.findAll({
    order: distance,
    where: sequelize.where(distance, { $lte: radius }),
    logging: console.log
})

where Position is defined as:

sequelize.define('Position', {
    location: DataTypes.GEOMETRY('POINT')
})

Note that Point requires the coordinates in the format of (longitude latitude)
