## background

These small utilities services are quite helpful in reducing noise when sharing links. You can input a very long URL address and it can output a much shorter version of it much easier to share around.

## setup envs

- go 1.17

- redis 3.2

## how it works

- storage layer

- short link generator

  - using SHA256 to hash the initial inputs

  - using BASE58 binary to text encoding

- forwarding

  - get the creation request body, parse it and extract the initial long url and userId

  - generate our shortened hash using `shortener.GenerateShortLink()`

  - store the mapping of output `hash/shortUrl` with the initial long url using `store.SaveUrlMapping()`
