Durability and state persistence for TanStack AI chats with @tanstack/ai-persistence. Routes to server chat persistence (withPersistence), client persistence (localStorage/IndexedDB), the store contracts, and adapter recipes. Distinguishes delivery durability (resumable streams) from conversation state. Use when conversations must survive reloads, multi-device, approvals, or server restarts — NOT for stream reconnect alone.

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 AI Persistence

> Builds on the `ai-core` skill in `@tanstack/ai`, and usually
> `ai-core/chat-experience`.

TanStack AI splits **delivery durability** from **state persistence**. They
share no code and solve different problems.

| **Delivery durability** | Reconnect to a stream still running | `memoryStream` / `@tanstack/ai-durable-stream` on the response; see resumable streams docs   |
| **State persistence**   | What is the conversation, later?    | Client `persistence` on `useChat` + server `withPersistence` from `@tanstack/ai-persistence` |

A replayable stream is **not** a saved conversation. A saved conversation is
**not** a live stream. Production apps often use both.

## Persistence is a contract, not a database

`@tanstack/ai-persistence` ships the **store interfaces**, the middleware that

How to install

The exact contents, by fingerprint
mdr add tanstack/ai/ai-persistence@sha256:4f7dd8ea773b4ee1

The line at the top of this page pins the label git:20261027.2f86841, 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.
