--description--

Build a full stack JavaScript app that is functionally similar to this: https://timestamp-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 Gitpod 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.

Note: Time zones conversion is not a purpose of this project, so assume all sent valid dates will be parsed with new Date() as GMT dates.

--hints--

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

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

A request to /api/:date? with a valid date should return a JSON object with a unix key that is a Unix timestamp of the input date in milliseconds (as type Number)

(getUserInput) =>
  $.get(getUserInput('url') + '/api/2016-12-25').then(
    (data) => {
      assert.equal(
        data.unix,
        1482624000000,
        'Should be a valid unix timestamp'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

A request to /api/:date? with a valid date should return a JSON object with a utc key that is a string of the input date in the format: Thu, 01 Jan 1970 00:00:00 GMT

(getUserInput) =>
  $.get(getUserInput('url') + '/api/2016-12-25').then(
    (data) => {
      assert.equal(
        data.utc,
        'Sun, 25 Dec 2016 00:00:00 GMT',
        'Should be a valid UTC date string'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

A request to /api/1451001600000 should return { unix: 1451001600000, utc: "Fri, 25 Dec 2015 00:00:00 GMT" }

(getUserInput) =>
  $.get(getUserInput('url') + '/api/1451001600000').then(
    (data) => {
      assert(
        data.unix === 1451001600000 &&
          data.utc === 'Fri, 25 Dec 2015 00:00:00 GMT'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

Your project can handle dates that can be successfully parsed by new Date(date_string)

(getUserInput) =>
  $.get(getUserInput('url') + '/api/05 October 2011, GMT').then(
    (data) => {
      assert(
        data.unix === 1317772800000 &&
          data.utc === 'Wed, 05 Oct 2011 00:00:00 GMT'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

If the input date string is invalid, the API returns an object having the structure { error : "Invalid Date" }

(getUserInput) =>
  $.get(getUserInput('url') + '/api/this-is-not-a-date').then(
    (data) => {
      assert.equal(data.error.toLowerCase(), 'invalid date');
    },
    (xhr) => {
      assert(xhr.responseJSON.error.toLowerCase() === 'invalid date');
    }
  );

An empty date parameter should return the current time in a JSON object with a unix key

(getUserInput) =>
  $.get(getUserInput('url') + '/api').then(
    (data) => {
      var now = Date.now();
      assert.approximately(data.unix, now, 20000);
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

An empty date parameter should return the current time in a JSON object with a utc key

(getUserInput) =>
  $.get(getUserInput('url') + '/api').then(
    (data) => {
      var now = Date.now();
      var serverTime = new Date(data.utc).getTime();
      assert.approximately(serverTime, now, 20000);
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
