shork

A MySQL / MariaDB database client for Gleam, based on MySQL-OTP. Heavily inspired by POG

import shork

pub fn main() {  
  // Start database connection
  let connection =
    shork.default_config()
    |> shork.user("root")
    |> shork.password("strong_password")
    |> shork.database("poke")
    |> shork.connect

  //  A SQL query with one parameter
  let query = "select name, hp from pokemon where id = ?"

  //  The  decoder for the returned data
  let row_decoder = {
    use name <- decode.field(0, decode.name)
    use hp <- decode.field(1, decode.int)

    decode.success(#(name, hp))
  }

  // Runs the query
  // The int 1 is given as parameter
  let assert Ok(response) = 
    shork.query(query)
    |> shork.parameter(shork.int(1))
    |> shork.returning(row_decoder)
    |> shork.execute(connection)

  response.rows
  |> should.equal([
    #("bulbasaur", 45)
  ])
}

Development

gleam run   # Run the project
gleam test  # Run the tests

To run tests, a mysql instance must be running with the following parameters:

• host: localhost
• port: 3306
• user: root
• password: root
• database: short_test

You can start it using docker like this:

docker run -d --rm -p 3306:3306 -e MYSQL_ROOT_PASSWORD="root" -e MYSQL_DATABASE=shork_test mysql
