Panier d’achat demystified

Hey there, dear reader!

Ever wonder how that magical little shopping cart icon, a.k.a. Panier d’achat, on every e-commerce website acts as your personal shopper, tirelessly amassing your desired goodies till you're ready for checkout? Ever caught yourself wondering, "how do they even do that?" Well, you're in for a treat. Let's embark on a journey to unfold the making and workings of this very important cogwheel in the machine of e-commerce. Fancy a trip? If yes, buckle up and read on!

What's the "Panier d’achat"?

Think of the "panier d'achat" like a personal butler at a supermarket. When you're shopping, you don't want to go to the cashier after every item you select, right? That'd take forever, and, let's be real, no one has the time. That's where our friendly butler a.k.a our "panier d’achat" comes in. It holds your selected items, remembers them, and gives you the freedom to continue shopping without a hitch.

How does it work?

You must have added items to your cart, shopped around some more, and finally decided to check out. You find that the items in your cart are exactly the ones you added earlier, and not mixed with thousands of other users' selections. This incredibly personalized shopping experience is made possible through the magic of cookies and sessions.

Each time you add a product, a session variable with the product details is created, allowing you to surf around and still maintain your unique cart. However, without you knowing it, your 'butler' is tirelessly working behind the scenes holding on to your selections,eagerly awaiting your return. Don't believe me? Try adding to the cart, close the window, open again, and voila! Your cart will still be populated.

See for yourself!

// assuming you're using Express.js
app.get('/add-to-cart/:id', (req, res) => {
    let productId = req.params.id;
    let cart = req.session.cart ? req.session.cart : {};
    cart[productId] = cart[productId] ? cart[productId] + 1 : 1;
    req.session.cart = cart;
    res.redirect('/');
});

In the code above, we're creating a 'cart' object in the user's session. Every time the user clicks 'add to cart', we increment the quantity of the product in the 'cart'. Easy, isn't it?

Wrapping it up...

A panier d'achat can be simple or complex depending on the website's needs. It effectively simplifies the user's shopping experience by providing a frictionless path between shopping and check out. Remember though, a great panier d’achat can improve conversions and bring in more money, while a poorly managed one can drive customers away. So, the design and easiness of your shopping cart matter! As we've seen today, it doesn't take a magician to make one, just some good old coding skills and an understanding of sessions and cookies.
