geocache

In-memory cache for storing bucketed geolocation data in Deno.

Usage

import { GeolocationCache } from "https://deno.land/x/geocache/mod.ts";

const cache = new GeolocationCache<string>(1);

cache.put(51, 3, "data");

let value = cache.get(51, 3);

Use Case

• Data can be stored in the cache and fetched from the cache given a latitude and longitude.
• Coordinates are grouped into buckets, and data is cached per bucket. Each bucket represents the space between the graticules.
• The space between the graticules is determined by the given interval in decimal degrees. A lower interval decreases the distance between the graticules and increases the accuracy of geolocation data, but it also increases the maximum cache size.
• The underlying cache is a TTL cache (more policies are planned).
