Timestamp Microservice Not Passing?

JavaScript
1

Tell us what’s happening:
So I uploaded my code on Heroku app and it is live on here: https://timestamp-exercise.herokuapp.com/

And my github source code here: https://github.com/synerjay/timestamp-exercise

But i still cannot pass this page?? It only passed the first story, even though everything seem to work on the microservice.

I did this exercise without cloning the Github repo from FCC. Is this the reason why it’s not passing?

Your code so far

If you open network tab you’ll see that the requests are blocked because of CORS.

https://expressjs.com/en/resources/middleware/cors.html

Relevant code in FCC boilerplate repo:

Sorry but I dont know what does that mean? I open the network tab and evrything seem to be fine.

Is that related to express? I 'm not using any express in my code btw.

Ok. I used the same code and retroifitted the provided Repl.it package and I got the first few stories passed except the last two:

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

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

const getTimestamp = date => ({ unix: date.getTime(), utc: date.toUTCString() });

app.get("/api/timestamp/:date", function (req, res) {
  const dateString = req.params.date;
  console.log(dateString);
  let timestamp;

  if (dateString === undefined || dateString.trim() === "") {
      let currentTime = new Date();
      timestamp = getTimestamp(currentTime);
    } else {
      const date = !isNaN(dateString) ? new Date(parseInt(dateString)) : new Date(dateString);

      if (!isNaN(date.getTime())) {
        timestamp = getTimestamp(date);
      } else {
        timestamp = { error : "Invalid Date" };
      }
    }
  res.writeHead(200, { "Content-Type": "application/json" });
  res.end(JSON.stringify(timestamp));
})

I made the condition for an “undefined” dateString and empty string and yet I cant pass the last two stories . Any insights? Thanks

Try adding ? after :date

Thank you! It worked! Is that a special feature in request parameters? I only learned /:parameters without the question mark. Would love to learn more about it

Url supports regex (? means 0 or 1 of preceding token, or in simpler words - make optional)
