Go API

A simple REST API with CRUD operations. The API will use an internal array, built and run on go version go1.10.4 but will probably work fine on earlier versions as well.

Endpoints and CRUD:

Health:

user@local:~$ curl 127.0.0.1:8080
"ok"

List all users:

user@local:~$ curl 127.0.0.1:8080/users
[{"id":"1","firstname":"James","lastname":"Hetfield","age":56},{"id":"2","firstname":"Lars","lastname":"Ulrich","age":55},{"id":"3","firstname":"Kirk","lastname":"Hammett","age":56},{"id":"4","firstname":"Robert","lastname":"Trujillo","age":55}]

Show singel user by ID:

user@local:~$ curl 127.0.0.1:8080/users/1
{"id":"1","firstname":"James","lastname":"Hetfield","age":56}

user@local:~$ curl 127.0.0.1:8080/users/3
{"id":"3","firstname":"Kirk","lastname":"Hammett","age":56}

Add user:

user@local:~$ curl -d '{"id":"5", "firstname":"Tom", "lastname": "Jones", "age":"75"}' -H "Content-Type: application/json" -X POST http://localhost:8080/users/5
[{"id":"1","firstname":"James","lastname":"Hetfield","age":56},{"id":"2","firstname":"Lars","lastname":"Ulrich","age":55},{"id":"3","firstname":"Kirk","lastname":"Hammett","age":56},{"id":"4","firstname":"Robert","lastname":"Trujillo","age":55},{"id":"5","firstname":"Tom","lastname":"Jones"}]

Delete user:

user@local:~$ curl -X DELETE http://localhost:8080/users/5
[{"id":"1","firstname":"James","lastname":"Hetfield","age":56},{"id":"2","firstname":"Lars","lastname":"Ulrich","age":55},{"id":"3","firstname":"Kirk","lastname":"Hammett","age":56},{"id":"4","firstname":"Robert","lastname":"Trujillo","age":55}]
