API Project: Timestamp Microservice

A full-stack JavaScript web development project. I wrote a blog post about the project, where you can read about programming concepts I used and about app's features and functionality. You can find it on my medium profile.

Technologies used

• Node.JS
• Express framework
• API
• JSON
• React.JS
• JavaScript
• HTML5
• CSS3

User stories :

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). 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. "2019-11-20") 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 2019 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.

Example usage:

• https://timestamp-microservice-lm.glitch.me/api/timestamp/2019-12-11
• https://timestamp-microservice-lm.glitch.me/api/timestamp/1576022400000
• https://timestamp-microservice-lm.glitch.me/api/timestamp/dog

Example output:

• {"unix":1576022400000, "utc":Wed, 11 Dec 2019 00:00:00 GMT"}
