TypeScript Lab: Featured Project Renderer

Concept

A renderer combines preview content, classification, descriptions, and technology tags.

Concept

A renderer combines preview content, classification, descriptions, and technology tags.

Objective & Explanation

What the project should make visible and why the concept matters.

Learning Target

Objective

Build a featured project panel from record relationships.

Explanation

A renderer combines preview content, classification, descriptions, and technology tags.

Project Plan

Structure, technologies, data boundary, and source connection.

Technologies

TypeScript
HTML
CSS

Data Layer

Use SQLite learning rows. Isolate destructive practice from important Sandbox records.

Sandbox Source

src/generator/generate.ts → renderHomeFeaturedProjects()

Build Instructions

Build only the focused behavior, then use the visual layer to inspect it.

Setup

Create the standalone project folder and listed files.

Implement

Implement the smallest version that demonstrates the concept.

Run & Inspect

Render the returned or changed data in the browser.

Code & Configuration

Starter configuration plus the focused implementation example.

Focused TypeScript

Implement this behavior first, then alter the input.

function renderFeatured(project: Project): string {
  return `
    <article class="featured">
      ${project.preview}
      <h2>${escapeHtml(project.title)}</h2>
      <p>${escapeHtml(project.description)}</p>
    </article>
  `;
}

Starter Configuration

Keep the project independently buildable.

package.json

{
  "type": "module",
  "scripts": {
    "build": "tsc",
    "start": "npm run build && node --enable-source-maps dist/server.js"
  },
  "devDependencies": {
    "@types/node": "^26.4.0",
    "typescript": "^7.0.2"
  }
}

tsconfig.json

{
  "compilerOptions": {
    "rootDir": "./src",
    "outDir": "./dist",
    "target": "ES2022",
    "module": "ES2022",
    "lib": ["ES2022", "DOM"],
    "types": ["node"],
    "strict": true,
    "sourceMap": true
  },
  "include": ["src/**/*.ts"]
}

Expected Visual Result

The output is the proof that the concept is working.

Visible Proof

The browser should visibly demonstrate: build a featured project panel from record relationships.
