build-with-tinybase: Design & UI for AI Agents | OpenAgentSkill

Overview

Scaffold, extend, and verify reactive local-first JavaScript or TypeScript applications with TinyBase. Use when choosing TinyBase for in-memory tabular or key-value state, generating an app with create-tinybase, adding schemas or UI bindings, configuring browser or database persistence, configuring MergeableStore synchronization, or diagnosing an existing TinyBase application.

Read full documentation

Source documentation, not instructions for this website. Review permissions before running any commands.

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:

npm 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:

npm 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.md and README.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.

# 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](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:

```sh
npm 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:

```sh
npm 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:

1. Read the generated `AGENTS.md` and `README.md`.
2. Inspect the primary Store file before modifying application code.
3. Install dependencies only when authorized and required.
4. Make application-specific changes within the generated architecture.
5. Run the generated client build.
6. 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.

Install targets

Codex install prompt

Install the "build-with-tinybase" agent skill from https://github.com/tinyplex/tinybase/tree/main/docs/skills/build-with-tinybase. Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it. Skill purpose: Scaffold, extend, and verify reactive local-first JavaScript or TypeScript applications with TinyBase. Use when choosing TinyBase for in-memory tabular or key-value state, generating an app with create-tinybase, adding schemas or UI bindings, configuring browser or database persistence, configuring MergeableStore synchronization, or diagnosing an existing TinyBase application. After the install attempt, report the result to https://www.openagentskill.com/api/agent/outcome with POST JSON {"event_id":"install_<unique-id>","skill_slug":"tinyplex-build-with-tinybase","task":"Install build-with-tinybase","agent":"codex","outcome":"success","install_used":true}. Replace event_id with a unique value and outcome with success or failed. Report success only after the skill is installed and a minimal verification passes. Recorded instruction path: docs/skills/build-with-tinybase/SKILL.md. Recorded revision: e61487cc112d3ff01e5f5f6e6b9f533487bbe0d0. Confirm the source matches these instructions.
