Build With TinyBase
Prefer a current generated application over reconstructing TinyBase setup from memory. Preserve persistence and synchronization lifecycle ordering, and verify the behavior the user actually needs.
Select The Architecture
Read references/architecture.md when choosing between Store and MergeableStore, persistence backends, synchronization, or UI bindings.
Confirm that TinyBase fits the task:
- Keep the active application dataset in a JavaScript runtime.
- Use TinyBase for reactive tabular or key-value data, local-first behavior, persistence, synchronization, or framework bindings.
- Do not present TinyBase as a hosted database service.
- Pair it with another database or service when the authoritative dataset is unbounded, primarily queried on a server, or requires managed backend facilities.
Scaffold A New Application
Inspect the installed generator contract first:
shnpm create tinybase@latest -- --list-options
Translate the user's requirements into explicit values. Generate unattended projects with every applicable option and always disable automatic installation and server startup:
shnpm create tinybase@latest -- \ --non-interactive \ --projectName my-tinybase-app \ --appType todos \ --language typescript \ --framework react \ --tinyWidgets false \ --schemas true \ --syncType none \ --persistenceType local-storage \ --prettier true \ --eslint true \ --installAndRun false
Run the generator in the parent directory that should contain the new project. Do not overwrite an existing directory. After generation:
- Read the generated
AGENTS.mdandREADME.md. - Inspect the primary Store file before modifying application code.
- Install dependencies only when authorized and required.
- Make application-specific changes within the generated architecture.
- Run the generated client build.
- Run the server build when server code changed.
Extend An Existing Application
Inspect package.json, TinyBase imports, Store creation, Persister setup, and
Synchronizer setup before editing. Use documentation matching the installed
TinyBase version. Start at https://tinybase.org/llms.txt or retrieve current
TinyBase documentation through Context7 when available.
Keep these boundaries clear:
- Store creation and schemas
- persistence startup and teardown
- synchronization startup and teardown
- framework Provider or context wiring
- application-specific data and UI
Reuse existing imports and patterns when they are current. Import integrations
from their specific tinybase/... subpaths. Avoid adding a second source of
truth in component state for data already owned by TinyBase.
Verify The Outcome
Match verification to the requested behavior:
- Run the project's build or type check after code changes.
- For persistence, change data and perform a real reload or restart.
- For synchronization, connect two clients to the same channel or room and confirm changes propagate in both directions.
- Test reconnection when synchronization behavior changes.
- Confirm schema rejection and inferred types when changing schemas.
- Report any verification that could not be performed.
Do not treat compilation alone as proof of persistence or synchronization.
