Unix Timestamp Microservice using Node.js and Express.js

FreeCodeCamp Timestamp Microservice

This is a Node.js (with Express.js) application which is part of the freeCodeCamp Back End Certification. It takes a date string and gives you back a JSON with Unix value and natural format for the given date.

FCC Constraints :

1. The API endpoint is GET [project_url]/api/timestamp/:date_string?
2. A date string is valid if can be successfully parsed by new Date(date_string) (JS) . Note that the unix timestamp needs to be an integer (not a string) specifying milliseconds. In our test we will use date strings compliant with ISO-8601 (e.g. "2016-11-20") because this will ensure an UTC timestamp.
3. If the date string is empty it should be equivalent to trigger new Date(), i.e. the service uses the current timestamp.
4. If the date string is valid the api returns a JSON having the structure {"unix": <date.getTime()>, "utc" : <date.toUTCString()> } e.g. {"unix": 1479663089000 ,"utc": "Sun, 20 Nov 2016 17:31:29 GMT"}.
5. If the date string is invalid the api returns a JSON having the structure {"unix": null, "utc" : "Invalid Date" }. It is what you get from the date manipulation functions used above.

User stories:

1. I can pass a string as a parameter, and it will check to see whether that string contains either a unix timestamp or a natural language date (example: January 1, 2016)
2. If it does contain a date or Unix timestamp, it returns both the Unix timestamp and the natural language form of that date.
3. If it does not contain a date or Unix timestamp, it returns null for those properties.

Example output:

{ "unix": 1450137600, "natural": "December 15, 2015" }
