TanStack DB patterns for client-first reactive data stores. Activates when implementing offline-first apps, local-first data, or reactive client databases. NOTE: Beta library - API may change.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# TanStack DB Patterns (Beta)
> **Beta Library**: TanStack DB is in beta. APIs may change between versions.
TanStack DB provides a client-first reactive data store with optional sync to remote sources.
## Core Concepts
- **Collections**: Named groups of documents (like tables)
- **Documents**: Individual records with unique IDs
- **Queries**: Reactive queries that update when data changes
- **Transactions**: Atomic operations across multiple documents
- **Sync**: Optional sync to remote backends
## Basic Setup
```typescript
// lib/db.ts
import { createDB, createCollection } from '@tanstack/db'
// Define document types
interface Post {
id: string
title: string
content: string
authorId: string
published: boolean
createdAt: number
updatedAt: number
}
interface User {
id: string
name: string
email: string
}
// Create database
export const db = createDB({
collections: {
posts: createCollection<Post>(),
users: createCollection<User>(),
},
})
```
## CRUD Operations
### Create
```typescript
import { db } from '@/lib/db'
// Insert a single document
const newPost = await db.posts.insert({
id: crypto.randomUUID(),
title: 'My Post',
…Read the whole file at its exact version.
How to install
mdr add smicolon/ai-kit/TanStack DB Patterns (Beta)@sha256:9fc4d7f063579475The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
