What's inside?

Hooks

These hooks are mostly bindings to the xmtp-js SDK that expose the underlying data in a React way.

Requirements

• Node 18+
• React 16.14+

Install

# npm
npm install @xmtp/react-sdk

# pnpm
pnpm install @xmtp/react-sdk

# yarn
yarn add @xmtp/react-sdk

Buffer polyfill

The Node Buffer API must be polyfilled in some cases. To do so, add the buffer dependency to your project and then polyfill it in your entry file.

Example

import { Buffer } from "buffer";

window.Buffer = window.Buffer ?? Buffer;

Create React App

If you see a lot of warnings related to source maps, see this issue to learn more.

Reference docs

Access the XMTP React SDK reference documentation.

Local-first architecture

This client SDK uses a local-first architecture to help you build a production-grade and performant app. To learn more about how we use a local-first architecture, see our official documentation.

Usage

Check out our official documentation to get started developing with XMTP and React.

XMTP network environments

XMTP provides production, dev, and local network environments to support the development phases of your project. To learn more about these environments, see our official documentation.

Important
When you create a client, it connects to the XMTP dev environment by default. To learn how to use the env parameter to set your client's network environment, see Configure the client.

Breaking revisions

Because this SDK is in active development, you should expect breaking revisions that might require you to adopt the latest SDK release to enable your app to continue working as expected.

XMTP communicates about breaking revisions in the XMTP Discord community, providing as much advance notice as possible. Additionally, breaking revisions in a release are described on the Releases page.

Deprecation

Older versions of the SDK will eventually be deprecated, which means:

• The network will not support and eventually actively reject connections from clients using deprecated versions.
• Bugs will not be fixed in deprecated versions.

The following table provides the deprecation schedule.

Announced	Effective	Minimum Version	Rationale
There are no deprecations scheduled for this SDK at this time.

Bug reports, feature requests, and PRs are welcome in accordance with these contribution guidelines.
