TypeScript Lab: Get All Records

Concept

A SELECT query returns rows that TypeScript can transform into interface elements.

Concept

A SELECT query returns rows that TypeScript can transform into interface elements.

Objective & Explanation

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

Learning Target

Objective

Query Sandbox records and render them as browser cards.

Explanation

A SELECT query returns rows that TypeScript can transform into interface elements.

Data Layer

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

Sandbox Source

src/datastore/queries.ts → getRecords()

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.

const rows = database.prepare(`
  SELECT *
  FROM records
  ORDER BY sort_order, title
`).all();

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: query Sandbox records and render them as browser cards.

Data: SQLite
