At Firstclasspostcodes, we use geohashes inside DynamoDB to quickly retrieve matching postcodes for a particular coordinate. Our solution has been adapted from [this original blog post](https://aws.amazon.com/blogs/mobile/geo-library-for-amazon-dynamodb-part-1-table-structure/) and we've extracted some of the code from an [existing NPM library](https://github.com/rh389/dynamodb-geo.js) to suit our own purposes.

## Getting Started

```

npm i @firstclasspostcodes/geohash --save

```

Then refer to the [documentation here](https://firstclasspostcodes.github.io/geohash) on how to start using it.
