OpenCode Mobile Chat (React Native)

A frontend-only React Native chat client for connecting to your OpenCode serve API.

Quick Start

1. Install dependencies

npm install

2. Start the dev server

npm run start

3. Open in Expo Go (or press a / i for emulator)

Gateway URL

At first launch, the app asks for your OpenCode Base URL. Default value:

http://127.0.0.1:4096

For real-device testing, use your computer's LAN IP (for example http://192.168.50.64:4096).

For deployment or remote real-device access, you need a public HTTPS endpoint (domain/IP via intranet tunneling). Due to Android and iOS network security restrictions, plain http:// endpoints are not supported.

Before using the app, start OpenCode server:

opencode serve --hostname 0.0.0.0 --port 4096

Internationalization

The app includes built-in i18n with English and Chinese (EN / ZH toggle in the header). English is the default language.

API Usage (Current)

• Creates a session with POST /session/
• Sends prompts with POST /session/:sessionID/prompt_async (with fallbacks)
• Polls messages from GET /session/:sessionID/message
• Verifies server with GET /global/health when saving Base URL

Notes

This project is still evolving and has many areas that can be improved. If you find unreasonable behavior or UX issues during use, please take a screenshot and open an issue.
