GEOCODING

 GEOCODING IS THE PROCESS OF CONVERTING ADDRESSES(LIKE A STREET ADDRESS) INTO GEOGRAPHIC CO-ORDINATES(LATITUDES & LONGITUDES) WHICH CAN BE USED TO PLACE MARKERS ON A MAP OR POSITION THE MAP.

HERE,WE USE GEOCODING API OF MAPBOX.

FORWARD GEOCODING: CONVERTS FROM ADDRESSES TO CO-ORDINATES

BACKWARD GEOCODING : CONVERTS FROM CO-ORDINATES TO ADDRESSES.

IN LISTING.JS FEW PARAMETERS ARE REQUIRED FROM GITHUB.

const mbxGeocoding = require("@mapbox/mapbox-sdk/services/geocoding");

const maptoken = process.env.MAP_TOKEN;

const geocodingClient = mbxGeocoding({ accessToken: maptoken });

module.exports.postNewListing = async (req, res, next) => {

  let response = await geocodingClient

    .forwardGeocode({

      query: req.body.listing.location,

      limit: 2,

    })

    .send();

  console.log(response.body.features[0].geometry);
