This is a simple web API built using Iron combined with ZIO JSON and ZIO HTTP.

It receives a user via a POST request to localhost/register.

Example request:

{
    "name": "totore",
    "password": "abc123",
    "age": 18
}

The passed fields must satisfy the following constraints:

• Name should be alphanumeric and have a length between 3 and 10
• Password should contain at least a letter, a digit and have a length between 6 and 20
• Age should be strictly positive

If an invalid value is passed, the response will look like this:

HTTP/1.1 400 Bad Request
Date: Wed, 23 Nov 2022 07:27:06 GMT
Connection: keep-alive
Content-Type: application/json
Content-Length: 133

{
  "message": [
    "Password must contain atleast a letter, a digit and have a length between 6 and 20"
  ]
}

Use the following command to run the example:

mill examples.formZio.run

Note: this command must be run in the Iron root directory.
