After cloning the repos

docker run --name mysql -p 3306:3306 -e "MYSQL_DATABASE=muzzdb" -e "MYSQL_USER=user" -e "MYSQL_PASSWORD=strongPass" -e "MYSQL_ROOT_PASSWORD=rootPass" -d  mysql:latest

or create a local db

• rename .env.example to .env
• update .env DB infos , these infos will be loaded in struct settings.Config using kenv
• run go run main.go

The first time you run the project, it will auto migrate models using struct, i used my ORM korm . So the same code will work with other sql dialects

• GET /user/create

you will notice password hash the name as a password, so you can copy the name of any user and tested.

• POST /login
• email : name@email.com
• password: name
• session encrypted using AES, i prefered over JWT and once implemented it's very straigtforward

this will return a token , and add it to cookies , you are authenticated, you are ready for /profiles you can change cookie session name using middlewares.CookieSessionName

• GET /profiles?age=x&gender=x this endpoint take only queryParams and get userId from request context passed through the AuthMiddleware

profiles are sorted by distance from the user_id it should look like this:

{
  "results": [
    {
      "id": 30,
      "name": "qxsjs",
      "gender": "male",
      "age": 52,
      "distanceFromMe": 1.7557933930191036
    },
    {
      "id": 5,
      "name": "vjhyf",
      "gender": "male",
      "age": 53,
      "distanceFromMe": 10.475076919529819
    },
    {
      "id": 20,
      "name": "dmyvl",
      "gender": "male",
      "age": 52,
      "distanceFromMe": 15.032404929858311
    },
    {
      "id": 6,
      "name": "mmzih",
      "gender": "male",
      "age": 56,
      "distanceFromMe": 19.181882524682916
    },
    {
      "id": 12,
      "name": "qfeml",
      "gender": "male",
      "age": 51,
      "distanceFromMe": 25.979435191333025
    },
    {
      "id": 11,
      "name": "pekad",
      "gender": "male",
      "age": 55,
      "distanceFromMe": 26.206583779720727
    }
  ]
}

• finaly POST /swipe expect in body:
• profileId : profile.Id
• preference : 'yes' or 'no'
• return matched only if both swiper yes

after swipe it should delete the profile and not see it again, you can check /profiles to verify

file handlers/util.go , these 2 functions took me some time, and remind me when i was studying mechanics :

• GenerateRandomLocation
• DistanceBetweenLocations
