Exceptions & Errors

When things go wrong in your PHP application, how do you handle it? 🤔 In this video, we dive into the art of exception handling and smart error management! 🎯

🔹 Throwing & catching exceptions—what, when, and why? 🎭
🔹 Best practices for handling errors (logging, notifications, feature toggles) 📝
🔹 When to use try/catch blocks (external APIs, limited resources) 🔄
🔹 The role of a global exception handler 🛑
🔹 Throwing custom exceptions to make your code more meaningful 🏗️
🔹 Why exceptions can be expensive 💰 and how to use error objects instead ⚡

Extracting Layout Components

In this video, we take a major step toward cleaner, more maintainable code by refactoring our static HTML into reusable layout components. ✂️➡️🧩

We’ll extract repeated sections of HTML into their own PHP partial view files:
• layout/_nav.view.php 🧭
• layout/_page_head.view.php 🧠
• layout/_header.view.php 🏷️
• layout/_page_foot.view.php 👣

This makes our pages easier to manage and sets the stage for a powerful layout system in future steps. 💡

By the end of this video, our project will be refactored and tagged as v3-layout-files—modular, organized, and ready to grow. 🚀

File-Based Storage

Ever wondered how to persist data without setting up a full database? In this episode, we explore file-based storage in Node.js — a simple way to read, write, and manage data using the filesystem.

Perfect for small projects, prototypes, or when you just need to get things done quickly ⚙️💾

👉 You’ll learn how to:
- Read and write JSON files asynchronously using fs/promises
- Implement full CRUD (Create, Read, Update, Delete) operations
- Handle data safely and understand file-based storage limitations
- Prepare your app for a transition to a real database later

Final Refactor

Your JavaScript framework is complete 🧠⚙️

In this final refactor, we polish our custom Node.js MVC framework — bringing everything together into a clean, organized, and extensible foundation worthy of real-world projects 💪

👉 In this episode, you’ll learn how to:

🧩 Move core classes like BaseController and BaseModel into the app layer
🧠 Refine the Router to handle static assets and feed request body data to middleware
🔒 Strengthen encapsulation and enforce single responsibility
✍️ Apply DRY principles and consistent coding style across the codebase
🎁 Add a fun “Easter Egg” route using your new framework

By the end, you’ll have built a lightweight but powerful Node.js framework — and gained a deep understanding of how professional frameworks like Express are designed under the hood 🚀

Final Review & Refactor

This video is all about the last layer of polish — a final walkthrough to tidy up code, views, and structure across the project. Here’s what we touched:

🖼️ Views
- index.view.php: added wider screen support with max-w-7xl.
- Removed a duplicate header to clean up the layout.

🧱 Framework Cleanup
- Database.php: fixed IDE issues and added helpful annotations.
- globals.php: minor tweaks to smooth dev experience.
- Model.php: highlighted PHPDoc comments, reviewed skip(), take(), and orderBy() methods.
- Session.php and View.php: both got the “FII” treatment (Fix IDE Issues).

📦 Http Layer
- Policies:
- UserPolicy: FII.
- Controllers:
- AuthenticationController, PhotoController, RegisterController, ReviewController, and UploadController: all reviewed and cleaned up.

🌐 Public Entry Point
- index.php: adjusted try/catch block for better error handling and clarity.


🎯 And that wraps things up at v28-review-refactor — setting the stage for a maintainable, scalable app with a solid foundation.

Fingerprint Refactoring

In this video, we tighten up our survey flow by performing several important refactors across models, routes, and controllers. These changes lay the groundwork for securely capturing survey responses and preventing duplicates.

Topics Covered
- Adding model relationships: Survey → responses, SurveyQuestion → answers
- Introducing a fingerprint-based protection to avoid duplicate survey submissions
- Updating database migrations to support hashed response identifiers
- Creating a clean, structured route layout for:
✔️ Viewing a survey
✔️ Submitting a fingerprint
✔️ Viewing the survey questions
✔️ Submitting survey answers
- Refactoring TakeSurveyController to support the new workflow

First Review & Refactor

It’s time to pause and sharpen the tools. In this video, we take a step back to review our progress and clean up our codebase, because maintainability is key to sustainable development. 🛠️

Here’s what we tackle in version v16-framework-refactor:


Emphasize the value of regular review and refactor sessions 🧠
Review our entry point (public/index.php) and extract logic into a new App class 📦
Create Framework/App as a singleton with a start() method to centralize bootstrapping 🚀
Address messy relative paths like '../../' by creating a dedicated Path helper class 🧭
Build Framework/Path as a singleton and introduce helpers like app(), root(), require_app(), and require_root()
Refactor all path-related code to use these clean, expressive helpers 📁
Move globals.php into the Framework directory to keep framework-related code encapsulated
Clean up and clarify all require/import statements 🔄


This refactor sets us up for a cleaner, more organized foundation—making our mini-framework easier to navigate, extend, and love. 💡

Flash Messages

Your app just got a voice 💬✨

It’s time to give your users clear feedback with flash messages — those friendly pop-ups that say things like “User created” or “Access denied.”

In this episode, we’ll bring interactivity and state together to create a polished, professional experience.

👉 In this episode, you’ll learn how to:

🚀 Implement flash messages using your existing session system
⚙️ Build alert helpers (req.alert.success, req.alert.error, req.alert.warn)
🧩 Pass flash data into your EJS views for dynamic display
💡 Automatically clear messages after they’re shown
🎨 Create a reusable _flash.ejs component for consistent UX

By the end, your Node.js app will communicate like a pro — giving users instant, elegant feedback ⚡️

Fluent Validation

In this step, we introduced a flexible and expressive validation system.


🧱 Created the Framework/Validation class and added a validate() helper to globals.php.
✍️ The goal was to write intuitive validation logic like:
validate('rating')->integer()->min(0)->max(5)->required();
validate('name')->string()->max(100);
validate('comment')->string()->max(1000);
🧪 This fluent API allowed chaining validation rules for each input field, improving both readability and maintainability.
🔧 We fixed the num_stars constraint in the migration SQL to properly enforce the rating range.
🧹 Ran the migration and reseeded the database to apply the changes.
🕵️ Also refined the reviews logic to default the name to “Anonymous” when one isn’t provided.


This new validation infrastructure enhances data safety and gives us a consistent, clean way to validate user input throughout the application.

Form Data & HTTP Post Handlers

In this episode, we begin capturing and storing survey data!

We’ll design the database schema for responses and answers, build out models, and wire up the controller logic to handle incoming survey submissions.

This continues our journey of transforming a static survey page into a dynamic Laravel application — step by step, the pragmatic way.

🧠 What You’ll Learn
- Designing survey_responses and survey_response_answers tables
- Creating migrations and Eloquent models
- Defining relationships between surveys, responses, and answers
- Updating POST routes to save incoming data
- Setting up a foundation for validation and fingerprinting
