Feature Request: Add Dockerfile for easier local development setup #2534
Description
Describe the solution you'd like
Hi team 👋
I’d like to suggest adding a Dockerfile (and possibly a docker-compose.yml) to OnchainKit to make local development and onboarding smoother for contributors.
Why this feature would be useful
Ensures a consistent development environment across systems (Node 20, pnpm 10, etc.).
Makes it much easier for new contributors to get started — no need for manual setup.
Useful for testing and CI since everything runs in a reproducible container.
Optional: could include live-reload support with Docker volumes for active development.
Describe alternatives you've considered.
Use Node 20 as the base image (matches current requirements).
Copy package.json / pnpm-lock.yaml, install dependencies with pnpm.
Copy the full repo and expose port 3000 for the playground.
Add .dockerignore to reduce image size.
Update README.md with an example of running via Docker.
