did you intend on removing this?

[davidjamesstone]

Yes - we're not using the reverse geocode. It was doing no harm but shouldn't be there.

[alexluckett]

Do the routes need removing?

[davidjamesstone]

Up to you. I kept them in previously in case we ever decided to use them.

/**
 * OS names search nearest by E/N
 * @param {number} easting - the easting
 * @param {number} northing - the northing
 * @param {string} apiKey - the OS api key
 */
export async function nearest(easting, northing, apiKey) {
  const endpoint = 'nearest'
  const url = `https://api.os.uk/search/names/v1/nearest?key=${apiKey}&point=${easting},${northing}&radius=1000&fq=local_type:Airfield%20local_type:Airport%20local_type:Bus_Station....`

  return getData(url, endpoint)
}

You think we'll ever need to do reverse geocoding?

[davidjamesstone]

If not, I'll remove the nearest service function and route to it.
