The security API

Your application will need to login a player or sign the player up. Here are the two methods for doing that.

Login: POST /api/session

There are three existing players in the database after seeding, all with the password “password”:

Expected payload sent to server:

{
  "email": "email@example.com",
  "password": "password"
}

Successful response:

{
  "token": "the token to use in your follow-up requests",
  "player": {
    "createdAt": "2019-05-01T08:33:40.799Z",
    "email": "yusuke@example.com",
    "id": 2,
    "name": "Yusuke",
    "updatedAt": "2019-05-01T08:33:40.799Z",
  }
}

Sign-up: POST /api/players

Expected payload sent to server:

{
  "name": "Marco",
  "password": "pwd",
  "email": "marco@example.com"
}

Successful response:

{
  "token": "the token to use in your follow-up requests",
  "player": {
    "createdAt": "2019-05-01T08:33:40.799Z",
    "email": "marco@example.com",
    "id": 4,
    "name": "Marco",
    "updatedAt": "2019-05-01T08:33:40.799Z",
  }
}

Logout: DELETE /api/session

You need to include the token received from logging in or signing up in this call as a Bearer token for the Authorization header. Set that on the header of the fetch call for this endpoint.

// Example code snippet
fetch(url, { headers: { Authorization: `Bearer ${token}` }})

Successful response:

{
  "message": "success"
}

Images

Some of the API results have image URLs associated with them. You can get them from this service. For example, if the service is hosted at http://localhost:8000, then http://localhost:8000/images/pokemon_snaps/5.svg will show the image for the Pokemon with the image URL /images/pokemon_snaps/5.svg.

The Pokemon API

This is all about listing and creating Pokemon.
