api

Go API

A simple REST API with CRUD operations. The API will use an internal array, built and run on go version go1.12 but will probably work fine on earlier versions as well.

How to build it

To build the api from source - you need to install go, pull the dependancies and compile.

Pull the dependancies based on the dependancy list in the repo.

user@local:~$ go get -d -v .

Compile the source code and create a binary for your target platform.

user@local:~$ go build
