<explanation>

1. Identify the project type and purpose

- This repository is a teaching/course project (“UC07: Desenvolver Aplicações Web”) containing multiple sub‑projects and exercises.

- It includes:

• Static HTML/CSS/JS examples (e.g., aula04‑02, aula27‑01, etc.)

• React single‑page applications (e.g., aula11‑03, aula18‑03, aula25‑03, projeto‑crud‑evento)

• A Node.js/Express backend for one full‑stack sample (aula08‑04/back‑end) paired with a React front‑end (aula08‑04/front‑end)

2. Analyze the file structure

- Top‑level folders are by lesson number (aula04‑02, aula08‑04, …, projeto‑crud‑evento).

- Within each lesson:

• Static examples: “css/” and “html/” subfolders.

• React apps: “public/”, “src/” with components, pages, assets, and build config (vite.config.js, package.json).

• Full‑stack (aula08‑04): distinct “back‑end/” and “front‑end/” directories.

3. Examine the README for additional insights

- Confirms the repo’s goal is instructional: teaching HTML, CSS, JS and React, plus Git usage.

- No overarching deployment or microservice architecture—each lesson is self‑contained.

4. How to create the system design diagram

a. Main components

- Static Exercises: simple HTML/CSS/JS pages

- React Front‑Ends: SPA modules under various lessons

- Node.js Back‑End: Express API (only in aula08‑04)

- Data Storage:

• In‑memory JS “database.js” (projeto‑crud‑evento)

• Real DB config in aula08‑04/config/database.js

- Build & Tooling: Vite, ESLint, npm

b. Relationships & interactions

- Static exercises: no runtime dependencies beyond the browser

- React SPAs: → fetch or import data (local JS modules or REST calls)

- Full‑stack sample (aula08‑04): Front‑end ↔ HTTP API ↔ Database

- projeto‑crud‑evento: SPA → in‑memory “database.js” module

c. Architectural patterns & design principles

- Separation of concerns: each lesson is an isolated module

- Component‑based UI: React components/pages in “src/components” and “src/pages”

- Layered architecture in aula08‑04: Controllers → Models → Database

- Module bundler/tooling: Vite for development and build

d. Key technologies

- HTML5/CSS3 for static

- React (via Vite) for SPA

- JavaScript ES modules

- Node.js + Express for REST API

- Vite.config.js, ESLint.config.js, npm

5. Tailoring the diagram to this teaching repo

- Group by lesson type:

1. Static HTML/CSS (visualized as green boxes)

2. React Front‑End SPAs (blue boxes)

3. Full‑Stack Sample (red region showing front and back)

4. Build/Tooling (gray region including Vite, ESLint, Git)

- Show that each lesson is self‑contained, with arrows only inside its scope.

6. Elements to include in the diagram

- Labels: Lesson names (aula04‑02, aula08‑04, projeto‑crud‑evento, etc.) and component names (Controller, Model, Page, Component)

- Directional arrows:

• Browser → Static files

• SPA → Data source (JS module or API)

• Front‑end → Back‑end → Database

- Color coding / shapes:

• Rectangles for folders/modules

• Cylinders for data stores

• Clouds for external tools (GitHub, browser)

7. Detailed capture of architecture

- For each React lesson: depict the entry point (main.jsx), routing to pages, and calls to service or data modules.

- For aula08‑04 full‑stack: show Express server, alunoController → alunoModel → DB, and front‑end Axios calls.

- For projeto‑crud‑evento: show SPA components (EventoCard, EventoForm) interacting with database.js.

By following these guidelines, you’ll produce a clear, color‑coded diagram that groups each lesson by technology stack, shows data flows for SPAs and the full‑stack sample, and highlights the course’s modular structure.
