--description--

Build a full stack JavaScript app that is functionally similar to this: https://request-header-parser-microservice.freecodecamp.rocks/. Working on this project will involve you writing your code using one of the following methods:

• Clone this GitHub repo and complete your project locally.
• Use our Replit starter project to complete your project.
• Use a site builder of your choice to complete the project. Be sure to incorporate all the files from our GitHub repo.

When you are done, make sure a working demo of your project is hosted somewhere public. Then submit the URL to it in the Solution Link field. Optionally, also submit a link to your project's source code in the GitHub Link field.

--hints--

You should provide your own project, not the example URL.

(getUserInput) => {
  assert(
    !/.*\/request-header-parser-microservice\.freecodecamp\.rocks/.test(
      getUserInput('url')
    )
  );
};

A request to /api/whoami should return a JSON object with your IP address in the ipaddress key.

(getUserInput) =>
  $.get(getUserInput('url') + '/api/whoami').then(
    (data) => assert(data.ipaddress && data.ipaddress.length > 0),
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

A request to /api/whoami should return a JSON object with your preferred language in the language key.

(getUserInput) =>
  $.get(getUserInput('url') + '/api/whoami').then(
    (data) => assert(data.language && data.language.length > 0),
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

A request to /api/whoami should return a JSON object with your software in the software key.

(getUserInput) =>
  $.get(getUserInput('url') + '/api/whoami').then(
    (data) => assert(data.software && data.software.length > 0),
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
