L0012

L0012 is the degenerate language in the Graffiticode ecosystem. It provides idempotent mapping of raw data values to task IDs.

What it does

L0012 maps arbitrary data values to task IDs idempotently - the same input always produces the same ID. It performs no computation or transformation; it simply stores values and returns stable identifiers.

Store: value → L0012 → task ID Retrieve: task ID → /data endpoint → value

Examples

10          → id1
{foo: 20}   → id2
"hello"     → id3

Submitting the same value twice returns the same task ID - no duplicates are created.

Purpose

All Graffiticode languages are idempotent by design. L0012 is the minimal case - the identity function of the ecosystem. Use it when you need to:

• Store raw data values and get stable IDs for later retrieval
• Reference data consistently across the system
• Deduplicate identical values

Form view

The form view simply displays the stored value as formatted JSON for inspection. Unlike L0011 (which renders interactive property editors), L0012's form view has no runtime purpose - it's purely for viewing the data.

Architecture

• packages/api - Node.js/Express backend (port 50012)
• packages/app - React/TypeScript frontend for viewing stored data

Getting started

# Install dependencies
npm install

# Start the API server
npm start

The API server runs on port 50012 by default.
