bun install
bun run dev

Check .env.example for available variables. They are optional for most local work and should not be set during testing unless a specific case requires them.

bun run build

Create .env from .env.example (or set APP_PORT directly in your shell), then run:

docker compose up -d --build

This serves the app on http://localhost:7200 by default.

To change the exposed host port:

• Linux/macOS:

APP_PORT=80 docker compose up -d --build

• PowerShell:

$env:APP_PORT=80
docker compose up -d --build

docker compose down

docker build -t terraink:latest .
docker run -d --name terraink -p 7200:80 --restart unless-stopped terraink:latest

The contribution guidelines are meant to keep Terraink easy to extend, review, and maintain over time. They are here to support a durable architecture, not to add unnecessary friction.

Read CONTRIBUTING.md before opening a PR.

• Branch from dev and target dev only. Do not open PRs against main.
• Fill out the pull request template completely when you open a PR.
• Keep contributions clean, modular, and aligned with the existing architecture.
• Avoid hard-coded values when constants, configuration, or reusable abstractions are more appropriate.
• AI-assisted coding is allowed, but submissions must be reviewed, refined, and intentionally engineered before review.

Terraink was inspired by MapToPoster by Ankur Gupta, originally released under the MIT license. Terraink is an independent reimplementation built from scratch using Bun, React, and TypeScript, and has since evolved significantly beyond the original concept.
