FreeCodeCamp Timestamp Microservice

This is a Node.js application which is part of the FCC Back End Certification. It takes a date string and gives back a JSON with Unix value and UTC value for the given date.

User stories:

1. 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)
2. 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
3. If the input date string is invalid, the api returns an object having the structure { error : "Invalid Date" }
4. An empty date parameter should return the current time in a JSON object with a unix and utc keys

Example usage:

1. [project url]/api/2021-12-03
2. [project url]/api/1639008000000
3. [project url]/api/
4. [project url]/api/hello

Example output:

1. {"unix":1638489600000,"utc":"Fri, 03 Dec 2021 00:00:00 GMT"}
2. {"unix":1639008000000,"utc":"Thu, 09 Dec 2021 00:00:00 GMT"}
3. {"unix":1647598428838,"utc":"Fri, 18 Mar 2022 10:13:48 GMT"}
