open.mp multiplayer game framework
A multiplayer mod for Grand Theft Auto: San Andreas that is fully backwards compatible with San Andreas Multiplayer.
This monorepo contains the web services and documentation for open.mp and SA-MP.
docs/Wiki documentation for SA-MP and open.mp in Markdown format including translations.emails/MJML email templates for account registration and other things.frontend/Next.js app for the https://open.mp site.prisma/Prisma database models for generating Go code and SQL migrations.app/Backend API for server listings, accounts, etc.
To work on the frontend, you mostly only need to focus on the frontend/ directory. Run npm commands in there such as npm run dev. See the readme file in there for more details.
The only files that the frontend need that are not in that directory are docs/ which it uses to for the https://open.mp/docs pages. .env is not used for frontend development.
When working on the backend, the root of the repository is where you need to be. The server application will assume it's being run from the root, not from within cmd/.
To start the API server, use Taskfile and run task, the default task is to build and run the API server.
The frontend, by default, only uses the live API. To change this you must edit any URLs from https://api.open.mp/... to http://localhost/....
You can run the following command to get a minimal development environment ready:
docker-compose -f .\docker-compose.dev.yml up -d
The .dev.yml Compose configuration contains services that aren't secure or production ready and suitable for local testing.
The frontend is deployed directly to Vercel from the master branch.
The backend is deployed to a server from the master branch using the docker-compose.yml file. You can simulate a production deployment by running docker-compose up.
We host large static assets such as images and videos on an S3-compatible object storage. This runs at assets.open.mp and you can use the task upload-assets to upload all public assets from frontend/public.
The easiest way to do this is via the Minio client. Once installed, set up an alias called omp:
mc alias set omp https://assets.open.mp ACCESS_KEY SECRET_KEY
Replace the two keys with the real keys.
Then run the task:
task upload-assets
