📡 Make requests to HTTP servers with fetch

Fetch

Bindings to JavaScript's built in HTTP client, fetch.

If you are running your Gleam project on the Erlang target (the default for new Gleam projects) then you will want to use a different library which can run on Erlang, such as gleam_httpc.

import gleam/fetch
import gleam/http/request
import gleam/http/response
import gleam/javascript/promise

pub fn main() {
  let assert Ok(req) = request.to("https://example.com")

  // Send the HTTP request to the server
  use resp <- promise.try_await(fetch.send(req))
  use resp <- promise.try_await(fetch.read_text_body(resp))

  // We get a response record back
  resp.status
  // -> 200

  response.get_header(resp, "content-type")
  // -> Ok("text/html; charset=UTF-8")

  promise.resolve(Ok(Nil))
}
