Code snippets 👾

Dodging the https trap

const http = require("http");
const https = require("https");

const myRequest = (url, cb) => {
  const protocol = url.includes("https") ? https : http;
  protocol
    .get(url, response => {
        // code....
    })
    .on("error", err => cb(err));
};

Countdown function

function updateCountdown() {
  var deadline = new Date("oct 31, 2019, 23:00:00").getTime();
  var now = new Date().getTime();
  var t = deadline - now;
  var days = Math.floor(t / (1000 * 60 * 60 * 24));
  var hours = Math.floor((t % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
  var minutes = Math.floor((t % (1000 * 60 * 60)) / (1000 * 60));
  var seconds = Math.floor((t % (1000 * 60)) / 1000);
  document.getElementById("countdown-time").innerText =
  `${days} days ${hours} hours ${minutes} minutes ${seconds} seconds`;
}

2015 rates comparison

var oldExchangeRates = {
  EUR: "1.44",
  USD: "1.56",
  JPY: "192.71",
  // etc
};

function oldRates(input) {
  let input2 = input;
  document.getElementById("old-rate").innerText =
    "On 21st July 2015, 1 GBP was " +
    oldExchangeRates[input2] + " " + input2 + ".";
}

Testing home route

test("home route should return status code 200", t => {
  supertest(router)
    .get("/")
    .expect(200)
    .expect("Content-type", /html/)
    .end((err, res) => {
      t.error(err);
      t.equal(res.statusCode, 200, "should return 200");
      t.end();
    });
});

---

Testing 404 route

test("404 route", t => {
  supertest(router)
    .get("/fhkwefhe")
    .expect(404)
    .end((err, res) => {
      t.error(err);
      t.equal(
        res.text,
        `<h1>404 page not found</h1>`,
        "Should return 404 page not found"
      );
      t.end();
    });
});

What we would have liked to improve 🏹

• We weren't able to use input validation to the back-end with our site design.
• Didn't have time to finish our stretch goals.
• Provide exchange rate variation percentages since 2015.

Questions from us 🧐

• Will we get a red, white and blue Brexit?

PS: Thanks Babyfather for letting us rip off his album cover

(We didn't actually ask 🙊)
