TypeScript Lab: One Record to One HTML File

Concept

Static generation converts structured data into a persistent browser document.

Concept

Static generation converts structured data into a persistent browser document.

Objective & Explanation

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

Learning Target

Objective

Generate one HTML document from one record object.

Explanation

Static generation converts structured data into a persistent browser document.

Project Plan

Structure, technologies, data boundary, and source connection.

Structure

project/
├── package.json
├── tsconfig.json
├── data/
├── tpl/
├── src/
│   └── generate.ts
└── output/

Technologies

TypeScript
Node.js
SQLite
HTML
CSS
JSON

Data Layer

Use a small local object, array, or JSON fixture so the transformation stays visible.

Sandbox Source

src/generator/generate.ts

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

Write the generated file and open it in the browser.

Code & Configuration

Starter configuration plus the focused implementation example.

Focused TypeScript

Implement this behavior first, then alter the input.

const html = `
<!doctype html>
<html>
  <body>
    <h1>${escapeHtml(record.title)}</h1>
  </body>
</html>
`;

writeFileSync(`output/${record.slug}.html`, html, "utf8");

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: generate one HTML document from one record object.

Data: JSON
