ROSETTA 09

Rosetta Stone Get All Records

Comparison Contract

Execute equivalent read queries and render equivalent record lists.

Comparison Contract

Execute equivalent read queries and render equivalent record lists.

Objective & Comparison Rule

Build each implementation without changing the shared behavior or visual target.

Rosetta Contract

Objective

Compare reading complete record collections across data stacks.

Comparison Rule

Execute equivalent read queries and render equivalent record lists.

Keep equivalent input, behavior, and visible output in every later language version.

Implementation Plan

Keep the comparison surface fixed while language syntax and runtime details change.

Build Instructions

Start with the first technology listed under Technologies, then reproduce the same behavior in each following implementation.

Freeze the Contract

Define the exact input, visible behavior, and expected output.

Build Initial Implementation

Implement the reference version with the same standalone visual layer.

Later Comparison

Rebuild without changing the contract.

TypeScript Implementation Reference

This implementation becomes the first concrete Rosetta comparison point.

Reference Code

Use the same input when building later language versions.

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

TypeScript Implementation Configuration

Keep the TypeScript implementation independently buildable; each implementation should keep its own required setup.

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"]
}

Comparison Dimensions

Record differences that teach language and runtime behavior rather than cosmetic syntax.

Compare

Syntax and data declarations
Typing and validation
Collections and standard-library operations
Modules and file organization
Runtime and build requirements
Database or HTTP APIs when applicable
Visible output and behavioral equivalence
