🌤️ Sunny

Here, the function send corresponds to a function that makes a HTTP request. For that, you can use HTTP clients such as gleam_httpc or gleam_fetch.

import gleam/dict
import gleam/io
import gleam/option

import sunny
import sunny/api/forecast
import sunny/api/forecast/instant
import sunny/api/geocoding
import sunny/measurement

pub fn main() {
  let sunny = sunny.new()

  let assert Ok(location) =
    sunny
    |> geocoding.get_first_location(
      geocoding.params("marseille")
      |> geocoding.set_language(geocoding.French),
    )
    // Make a HTTP request
    |> send
    |> geocoding.get_first_result

  let assert Ok(forecast_result) =
    sunny
    |> forecast.get_forecast(
      forecast.params(geocoding.location_to_position(location))
      |> forecast.set_current([instant.Temperature2m]),
    )
    // Make a HTTP request
    |> send
    |> forecast.get_result

  let assert option.Some(current_data) = forecast_result.current

  let assert Ok(temperature) =
    current_data.data |> dict.get(instant.Temperature2m)

  io.println(
    location.name
    <> "'s current temperature is : "
    <> measurement.to_string(temperature),
  )
}
