TypeScript Lab: Auto Slug and Unique ID

Concept

Readable slugs and collision-resistant IDs solve different identity problems.

Concept

Readable slugs and collision-resistant IDs solve different identity problems.

Objective & Explanation

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

Learning Target

Objective

Generate stable slugs and unique IDs from record titles.

Explanation

Readable slugs and collision-resistant IDs solve different identity problems.

Project Plan

Structure, technologies, data boundary, and source connection.

Structure

project/
├── package.json
├── tsconfig.json
├── index.html
├── styles.css
└── src/
    └── app.ts

Technologies

TypeScript
Node.js
SQLite
HTML
CSS

Data Layer

No persistent data layer. Keep all demonstration values inside the standalone project.

Sandbox Source

src/local-editor/server.ts → slugify(), uniqueId()

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

Change one input and observe the visible output change.

Code & Configuration

Starter configuration plus the focused implementation example.

Focused TypeScript

Implement this behavior first, then alter the input.

import { randomUUID } from "node:crypto";

function uniqueId(title: string): string {
  const slug = slugify(title).slice(0, 42);
  const suffix = randomUUID().replace(/-/g, "").slice(0, 10);
  return `rec-${slug}-${suffix}`;
}

Starter Configuration

Keep the project independently buildable.

package.json

{
  "type": "module",
  "scripts": { "build": "tsc" },
  "devDependencies": { "typescript": "^7.0.2" }
}

tsconfig.json

{
  "compilerOptions": {
    "rootDir": "./src",
    "outDir": "./dist",
    "target": "ES2022",
    "module": "ES2022",
    "lib": ["ES2022", "DOM"],
    "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 stable slugs and unique IDs from record titles.

Data: None
