Hello Dev Community! 👋
It is officially Day 71 of my unbroken 100-day full-stack engineering run! After mastering polymorphic multi-part storage configurations yesterday, today I successfully crossed into core transactional operations: Engineering a High-Fidelity "Confirm and Pay" Checkout View and Wiring Database Inbound Array Modifications!
In real-world booking platforms, processing a successful transaction requires more than updating an absolute view; you have to link documents relationally across collections. Today, I wired that entire execution pipeline together!
🧠 What I Handled on Day 71 (Checkout Engineering & Target Mutations)
As displayed across my latest system files in "Screenshot (164).png" and "Screenshot (165).jpg", handling payments runs through structured backend steps:
1. High-Fidelity Checkout Component (/reserve)
I built out the detailed split-pane verification interface visible in "Screenshot (164).png". The layout captures target trip date selections, total guests parameter caps, card input structures, and computes subtotal ledgers dynamically:
-
Base Compute:
$9000 x 5 nights = $45000. -
Transactional Upgrades: Appending structured service charges (
$85) and local tax calculations ($42) to update the final sum directly to$45127.
2. Live Document Array Mutators (MongoDB User List Insertion)
The most crucial logic happens when the user clicks the primary validation trigger labeled Confirm and pay:
- The inbound route controller extracts the targeted property identity token (
home._id) via an embedded hidden input container. - Instead of running isolation updates, it issues an atomized update operation straight into our MongoDB user records array (e.g., using Mongoose operators like
$pushor tracking active profiles inside our custom data state loops). - This appends the exact property listing target ID directly into the user's booking history array database matrix!
🛠️ View Markup Code Integration View
As showcased in my VS Code script structure in "Screenshot (165).jpg", the pricing breakdown variables parse raw parameters to create an adaptive enterprise layout experience:
html
<!-- Excerpt from payment.ejs showing price summaries -->
<div class="price-details-box">
<h2>Price details</h2>
<p>$<%= home.price %> x 5 nights</p>
<p>Service fee: $85</p>
<p>Taxes: $42</p>
<strong>Total (USD): $<%= home.price * 5 + 85 + 42 %></strong>
</div>
