http_server_mock_js

JavaScript/Node.js runtime for http_server_mock — a WireMock-style HTTP mock server library for Gleam. This package provides the server adapter that runs on the JavaScript target using Node.js’s http module in a Worker thread, with synchronous communication via SharedArrayBuffer.

You need both this package and http_server_mock to use the library. See the http_server_mock README for the full API documentation.

Installation

gleam add http_server_mock http_server_mock_js

Make sure your gleam.toml targets JavaScript:

[javascript]
target = "javascript"

Usage

Pass the adapter from this package to http_server_mock.new/1:

import gleam/http
import http_server_mock
import http_server_mock_js
import http_server_mock/matcher
import http_server_mock/response
import http_server_mock/stub_builder
import http_server_mock/verify

pub fn my_test() {
  let server =
    http_server_mock.new(http_server_mock_js.server())
    |> http_server_mock.with_stub(
      stub_builder.new()
      |> stub_builder.matching(
        matcher.new()
        |> matcher.method(http.Get)
        |> matcher.path("/hello"),
      )
      |> stub_builder.responding_with(
        response.new()
        |> response.status(200)
        |> response.body("world"),
      )
      |> stub_builder.build(),
    )
    |> http_server_mock.start()

  let url = http_server_mock.base_url(server) <> "/hello"
  // ... make HTTP calls ...

  verify.called(server, matcher.new() |> matcher.path("/hello"))

  http_server_mock.stop(server)
}
