# Rhai Engine Worker UI

A Yew-based WASM interface to monitor Rhai workers.

## Prerequisites

- Rust: Install from [rust-lang.org](https://www.rust-lang.org/tools/install)
- Trunk: Install with `cargo install trunk`
- A backend service providing the necessary API endpoints (see below).

## Backend API Requirements

This UI expects a backend service to be running that can provide data from Redis. The UI will make requests to the following (example) endpoints:

- `GET /api/worker/{worker_name}/tasks_and_stats`: Returns initial `WorkerData` including a list of `TaskSummary` and initial `QueueStats`.
  - `WorkerData`: `{ "queue_stats": { "current_size": u32, "color_code": "string" }, "tasks": [TaskSummary] }`
  - `TaskSummary`: `{ "hash": "string", "created_at": i64, "status": "string" }`
- `GET /api/worker/{worker_name}/queue_stats`: Returns current `QueueStats` for polling.
  - `QueueStats`: `{ "current_size": u32, "color_code": "string" }`
- `GET /api/task/{task_hash}`: Returns `TaskDetails`.
  - `TaskDetails`: `{ "hash": "string", "created_at": i64, "status": "string", "script_content": "string", "result": "optional_string", "error": "optional_string" }`

**Note:** The API endpoints are currently hardcoded with relative paths (e.g., `/api/...`). This assumes the backend API is served from the same host and port as the Trunk development server, or that a proxy is configured.

## Development

1.  Navigate to the `rhai_engine_ui` directory:
    ```bash
    cd /Users/timurgordon/code/git.ourworld.tf/herocode/rhailib/rhai_engine_ui/
    ```
2.  Run the development server:
    ```bash
    trunk serve --port 8081
    ```
3.  Open your browser to `http://127.0.0.1:8081`.

## Building for Release

```bash
trunk build --release
```
This will output static files to the `dist` directory.
