base on A full-stack, syncing database that runs on both server and client. Pluggable storage (indexeddb, sqlite, durable objects), syncs over websockets, and works with your favorite framework (React, Solid, Vue, Svelte).  # Overview [Triplit](https://www.triplit.dev) is an open-source database that syncs data between server and browser in real-time. Triplit provides a real-time syncing datastore that you can drop into your app as a Typescript package. Triplit handles storing your data on the server and intelligently syncs your queries to your clients. **We call this type of system a “full stack database”**—you can watch our presentation to the [Local First community](https://localfirstweb.dev/) on this new paradigm [here](https://www.youtube.com/watch?v=SEB-hF1F-UU&t=1465s). Triplit brings together: 🔄 **Real-time sync** with incremental updates and conflict resolution at the property level 🏠 **Local caching** powered by a full-fledged client-side database 💽 **Durable server-side storage** with an admin dashboard 🔌 **Pluggable storage providers** like SQLite, IndexedDB, LevelDB, Memory, etc 😃 **Optimistic updates** to make every interaction feel fast 🔗 **Relational querying** for complex data models 🛫 **Offline-mode** with automatic reconnection and consistency guarantees 🔙 **Rollback and retry management** on failed updates 🗂️ **Schemas** for data safety and Typescript autocompletion 🔐 **Authorization** that's enforced on the server for both read and writes 🤝 **Collaboration/Multiplayer** powered by [CRDTs](https://en.wikipedia.org/wiki/Conflict-free_replicated_data_type) 🏎️ **Low latency** with minimal network traffic using delta patches 📝 **Simple API** for querying and mutating data in both vanilla Javascript and React ✅ **Fully open-source!** # Monorepo Overview In `triplit/packages` you can find the various projects that power Triplit: - [TriplitDB](https://github.com/aspen-cloud/triplit/tree/main/packages/db) - Designed to run in any JS environment (browser, node, deno, React Native, etc) and provide expressive, fast, and live updating queries while maintaining consistency with many writers over a network. - [Client](https://github.com/aspen-cloud/triplit/tree/main/packages/client) - Browser library to interact with local and remote TriplitDBs. - [CLI](https://github.com/aspen-cloud/triplit/tree/main/packages/cli) - CLI tool with commands to scaffold a project, run the full-stack development environment, migrate a server, and more. - [React](https://github.com/aspen-cloud/triplit/tree/main/packages/react) - React bindings for @triplit/client. - [Svelte](https://github.com/aspen-cloud/triplit/tree/main/packages/svelte) - Svelte bindings for @triplit/client. - [Console](https://github.com/aspen-cloud/triplit/tree/main/packages/console) - App for viewing and mutating data in Triplit projects and managing their schemas. - [Server](https://github.com/aspen-cloud/triplit/tree/main/packages/server) - Node server for syncing data between Triplit clients. - [Server-core](https://github.com/aspen-cloud/triplit/tree/main/packages/server-core) - Protocol agnostic library for building servers running Triplit. - [Docs](https://github.com/aspen-cloud/triplit/tree/main/packages/docs) - Triplit docs, built with Nextra. - [Types](https://github.com/aspen-cloud/triplit/tree/main/packages/types) - Shared types for various Triplit projects. - [UI](https://github.com/aspen-cloud/triplit/tree/main/packages/ui) - Shared UI components for Triplit frontend projects, built with [shadcn](https://ui.shadcn.com/). # Quick Start Start a new project. ```bash npm create triplit-app@latest my-app ``` Or add the dependencies to an existing project. ```bash npm install --save-dev @triplit/cli npm run triplit init ``` Define a [schema](https://www.triplit.dev/docs/schemas) in `my-app/triplit/schema.ts`. ```ts import { Schema as S, ClientSchema } from '@triplit/client'; export const schema = { todos: { schema: S.Schema({ id: S.Id(), text: S.String(), completed: S.Boolean({ default: false }), }), }, } satisfies ClientSchema; ``` Start the Triplit development [sync server](https://www.triplit.dev/docs/local-development). ```bash npm run triplit dev ``` This will output some important [environmental variables](https://www.triplit.dev/docs/local-development#additional-environment-variables) that your app will need to sync with the server. Add them to your `.env` file (Vite example below). ```bash VITE_TRIPLIT_SERVER_URL=http://localhost:6543 VITE_TRIPLIT_TOKEN=copied-in-from-triplit-dev ``` Define a [query](https://www.triplit.dev/docs/client/query) in your App (React example below). ```tsx import { TriplitClient } from '@triplit/client'; import { useQuery } from '@triplit/react'; import { schema } from '../triplit/schema'; const client = new TriplitClient({ schema, serverUrl: import.meta.env.VITE_TRIPLIT_SERVER_URL, token: import.meta.env.VITE_TRIPLIT_TOKEN, }); function App() { const { results: todos } = useQuery(client.query('todos')); return ( <div> {Array.from(todos.values()).map((todo) => ( <div key={todo.id}> <input type="checkbox" checked={todo.completed} onChange={() => client.update('todos', todo.id, (todo) => ({ todo.completed = !todo.completed, }) } /> {todo.text} </div> ))} </div> ); } ``` Start your app, open another browser tab, and watch the data sync in real-time.
