http://localhost:8080/cards/undefined?side=answer
extends layout.pug
block content
section#content
h2= text
if hint
p
i Hint: #{hint}
a(href='/' + `${id}?side=${sideToShow}`)= sideToShowDisplay
const express = require('express');
const router = express.Router();
const { data } = require('../data/flashcardData.json');
const cards = data.cards;
router.get('/:id', (req, res) => {
const { side } = req.query;
const { id } = req.params;
const text = cards[id][side];
const { hint } = cards[id];
const templateData = { text };
console.log(id);
if (side === 'question') {
templateData.hint = hint;
templateData.sideToShow= 'answer';
templateData.sideToShowDisplay= 'Answer';
} else if (side === 'answer') {
templateData.sideToShow= 'question';
templateData.sideToShowDisplay= 'Question';
}
res.render('cards', templateData);
});
module.exports = router;

3,656 PointsI am Aware it Doesn't really matter that it says local host I was just showing the issue I was having which when the id variable is called it comes out undefined in the URL. The other portion of the URL's Variable works and when I console log it, it works.

const templateData = { text, id };
and you should be able to reference it from the .pug template i.e.
a(href=`${id}?side=${otherSide}`)
And remove the '/' before the ${id}, that was screwing mine up.
I got it to work without the id entirely. My code looks like this:
a(href=`?side=${otherSide}`)
