Map Mock examples

Change Request URL and Method. It can be used for mapping APIs from PROD to DEV.

  return {
    url: "http://127.0.0.1:8080/json",
    method: "GET"
  }
}

on_request := func(env, req) {
  return {
    header: {
      "Referer": "https://www.google.com/",
      "Accept-Encoding": "gzip"
    },
    query: {
      "name": "EchoProxy",
      "date": "2024-08-08"
    }
  }
}

Change Response Body. It can be used for mocking APIs for debugging and testing.

on_response := func(env, res) {
  return {
    body: {
      "app": "EchoProxy",
      "comments": "Modern API debugging Proxy with powerful Map Mock",
      "date": "2024-06-30"
