Deploy and Host SpacetimeDB on Railway

SpacetimeDB is a realtime ultra-fast backend framework and database for apps and games. Server logic can be written in TypeScript, C#, C++, or Rust with automatic client synchronization. Table schema and application logic is defined in the same project and uploaded to SpacetimeDB as a single Wasm binary or JavaScript bundle.

About Hosting SpacetimeDB

Hosting SpacetimeDB requires running the first-party docker image clockworklabs/spacetime and exposing port 3000. Additionally to ensure persistence a volume is required on the path /stdb.

At this point SpacetimeDB is ready to run multiple databases that can be published using the spacetime publish cli command.

Common Use Cases

Typical use cases for SpacetimeDB as a backend framework are:

• Running the backend to handle state synchronization for a realtime web application like figma.
• Handling state persistence and synchronization for a realtime multiplayer game. For example the MMORPG BitCraft Online runs entirely on SpacetimeDB.
• Synchronizing state between running agents that publish updates and subscribe to a shared state.

Implementation Details

A SpacetimeDB project can be initialized by installing the spacetime cli and running spacetime init.

To publish a new database to a particular deployment on Railway you need to first add to the list of servers by running spacetime server add --url railway.

You can then run spacetime publish -s railway to deploy your database to your railway app.
