spacetimedb

Entry point for the SpacetimeDB skill collection. SpacetimeDB combines a database, server-side application logic, and realtime client sync into one programmable backend.

How to use this skill

1. Find the specialized skill in the router below that best matches the task.
2. Load that skill's SKILL.md and follow its guidance.
3. Open only the referenced Markdown files that match the current subtask.
4. If no sub-skill fits, search copied references in the most likely skill before falling back to external docs.

Do not load every SpacetimeDB reference file by default. Start with the focused skill body, then load a reference only when the body says the details are needed or the task requires exact API syntax.

Core model

• A database is a published instance of a module; the module defines tables, reducers, procedures, views, and public client surface.
• Tables store state. Public tables can be subscribed to by clients; private tables are server-only unless exposed through views or reducers.
• Reducers are transactional entrypoints for state changes. Failed reducers roll back their table mutations.
• Procedures can return values and perform external work such as HTTP requests; open transactions explicitly when they need database writes.
• Views expose derived, read-only data. Prefer anonymous views when the result does not depend on the caller.
• Clients use generated bindings, connect with DbConnection, subscribe to rows, read the local cache, and invoke reducers or procedures.
