Cartesian API

A simple API to get manhattan distance between 1xN vectors.

Sample:

GET "/api/points?x=1,y=1,distance=3"

Params:

"x": integer, required

"y": integer, required

"distance": integer, required

Return points ordered by increasing distance, limited by informed distance threshold:

[
    {
        "x": 2,
        "y": -8
    },
    {
        "x": 18,
        "y": -3
    },
]

Inside data dir exists a file called "points.json" that are used to calculate distances between informed coordinate

Running

Important!

As we using go mod as dependency manager, maybe you will need to export GO111MODULE env var before run this project.

Some people have dep and mod together, to avoiding conflicts with go dep, just disable go mod when you not using, this will prevent mod to create files like go.mod and go.sum in your other projects with dep.

#on/off/auto
export GO111MODULE=auto

Inside root directory exists a Makefile to better instrumentation of that available commands:

By default the app will run on localhost:8080, to change port:

export PORT=3000

Running the project

make run

Testing

make tests

Coverage

make coverage

Updating dependencies

Requirements

• Go >= 1.12.x

• Go mod

I hope you enjoy :D
