## Changes 🏗️
Adds Redis-based SSE reconnection support for long-running CoPilot
operations (like Agent Generator), enabling clients to reconnect and
resume receiving updates after disconnection.
### What this does:
- **Stream Registry** - Redis-backed task tracking with message
persistence via Redis Streams
- **SSE Reconnection** - Clients can reconnect to active tasks using
`task_id` and `last_message_id`
- **Duplicate Message Fix** - Filters out in-progress assistant messages
from session response when active stream exists
- **Completion Consumer** - Handles background task completion
notifications via Redis Streams
### Architecture:
```
1. User sends message → Backend creates task in Redis
2. SSE chunks written to Redis Stream for persistence
3. Client receives chunks via SSE subscription
4. If client disconnects → Task continues in background
5. Client reconnects → GET /sessions/{id} returns active_stream info
6. Client subscribes to /tasks/{task_id}/stream with last_message_id
7. Missed messages replayed from Redis Stream
```
### Key endpoints:
- `GET /sessions/{session_id}` - Returns `active_stream` info if task is
running
- `GET /tasks/{task_id}/stream?last_message_id=X` - SSE endpoint for
reconnection
- `GET /tasks/{task_id}` - Get task status
- `POST /operations/{op_id}/complete` - Webhook for external service
completion
### Duplicate message fix:
When `GET /sessions/{id}` detects an active stream:
1. Filters out the in-progress assistant message from response
2. Returns `last_message_id="0-0"` so client replays stream from
beginning
3. Client receives complete response only through SSE (single source of
truth)
### Frontend changes:
- Task persistence in localStorage for cross-tab reconnection
- Stream event dispatcher handles reconnection flow
- Deduplication logic prevents duplicate messages
### Testing:
- Manual testing of reconnection scenarios
- Verified duplicate message fix works correctly

🧢 Getting Started
This project uses pnpm as the package manager via corepack. Corepack is a Node.js tool that automatically manages package managers without requiring global installations.
For architecture, conventions, data fetching, feature flags, design system usage, state management, and PR process, see CONTRIBUTING.md. For Playwright and Storybook testing setup, see TESTING.md.
Prerequisites
Make sure you have Node.js 16.10+ installed. Corepack is included with Node.js by default.
Setup
1. Enable corepack (run this once on your system):
corepack enable
This enables corepack to automatically manage pnpm based on the packageManager field in package.json.
2. Install dependencies:
pnpm i
3. Start the development server:
Running the Front-end & Back-end separately
We recommend this approach if you are doing active development on the project. First spin up the Back-end:
# on `autogpt_platform`
docker compose --profile local up deps_backend -d
# on `autogpt_platform/backend`
poetry run app
Then start the Front-end:
# on `autogpt_platform/frontend`
pnpm dev
Open http://localhost:3000 with your browser to see the result. If the server starts on http://localhost:3001 it means the Front-end is already running via Docker. You have to kill the container then or do docker compose down.
You can start editing the page by modifying app/page.tsx. The page auto-updates as you edit the file.
Running both the Front-end and Back-end via Docker
If you run:
# on `autogpt_platform`
docker compose up -d
It will spin up the Back-end and Front-end via Docker. The Front-end will start on port 3000. This might not be
what you want when actively contributing to the Front-end as you won't have direct/easy access to the Next.js dev server.
Subsequent Runs
For subsequent development sessions, you only need to run:
pnpm dev
Every time a new Front-end dependency is added by you or others, you will need to run pnpm i to install the new dependencies.

🔄 Data Fetching
See CONTRIBUTING.md for guidance on generated API hooks, SSR + hydration patterns, and usage examples. You generally do not need to run OpenAPI commands unless adding/modifying backend endpoints.
🚩 Feature Flags

📙 Storybook
Storybook is a powerful development environment for UI components. It allows you to build UI components in isolation, making it easier to develop, test, and document your components independently from your main application.
Purpose in the Development Process
- Component Development: Develop and test UI components in isolation.
- Visual Testing: Easily spot visual regressions.
- Documentation: Automatically document components and their props.
- Collaboration: Share components with your team or stakeholders for feedback.
How to Use Storybook
-
Start Storybook: Run the following command to start the Storybook development server:
pnpm storybookThis will start Storybook on port 6006. Open http://localhost:6006 in your browser to view your component library.
-
Build Storybook: To build a static version of Storybook for deployment, use:
pnpm build-storybook -
Running Storybook Tests: Storybook tests can be run using:
pnpm test-storybook -
Writing Stories: Create
.stories.tsxfiles alongside your components to define different states and variations of your components.
By integrating Storybook into our development workflow, we can streamline UI development, improve component reusability, and maintain a consistent design system across the project.
