Browser chat persistence on useChat / ChatClient: localStoragePersistence, sessionStoragePersistence, indexedDBPersistence. Client-authoritative (adapter, full transcript) vs server-authoritative (persistence: true, no client cache). Reload restore, pending interrupts, mid-stream rejoin with delivery durability. Use for SPA reload durability — NOT server history alone. Also covers generation hooks (useGenerateImage etc.), which take only the server-driven mode: persistence: true hydrates the…

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

# Client Persistence

> Builds on ai-core, and on `ai-core/chat-experience` for `useChat` itself.
>
> **No extra package.** The adapters below ship in the **framework** packages
> (`@tanstack/ai-react` and friends, re-exported from `@tanstack/ai-client`),
> so browser persistence needs nothing installed beyond what a chat UI already
> has. The **server** half is a separate package — see
> `@tanstack/ai-persistence` and its `ai-persistence/server` skill.

A `ChatClient` / `useChat` keeps messages in memory. The `persistence` option
stores one record per `threadId` so a reload can repaint the transcript,
restore a pending interrupt, and rejoin an in-flight run.

Import adapters from the **framework package** (not `@tanstack/ai-client`
unless vanilla JS):

```tsx
import {
  useChat,
  fetchServerSentEvents,
  localStoragePersistence,
  sessionStoragePersistence,
  indexedDBPersistence,
} from '@tanstack/ai-react'
```

How to install

The exact contents, by fingerprint
mdr add tanstack/ai/ai-core/client-persistence@sha256:d815f1374824cda5

The line at the top of this page pins the label git:20260909.53e2ec0, 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.
