ChuckandClaude Opus 5 a694b23cd1 feat(web): serve plugin-declared widgets, and actually ask for them
LEDMatrixWidgets.loadPluginWidget has always fetched
/static/plugin-widgets/<plugin>/<widget>.js, and docs/widget-guide.md has
always documented that path, but nothing served it. soccer-scoreboard has
shipped a 17KB widgets/custom-leagues.js since August that could never
load. Both halves were missing, not just the route:

- serve_plugin_widget serves the script from the plugin's widgets/
  directory as text/javascript. The manifest is the allowlist -- only a
  widget the plugin declares is reachable -- so installing a plugin does
  not publish everything it ships. Path handling mirrors the sibling
  serve_plugin_web_ui: allowlist regexes, os.path.basename, resolve() +
  relative_to() containment, and the ledmatrix- prefix fallback. The
  declared script name is guarded too, since it comes from the plugin
  rather than the request.

- The config form never requested one. Its x-widget dispatch is a
  hardcoded list of core widget names, so a plugin's own widget fell
  through to a plain text input. An unrecognised x-widget on a string
  field now asks ensureWidget() for it. The text input stays as the
  fallback and is removed only once the widget has actually rendered, so
  a missing or broken widget costs the user an editor rather than their
  configured value on the next save.

- manifest_schema.json gains "widgets", so the declaration is validated
  rather than merely tolerated by additionalProperties.

Verified in a browser against the real partial: a declared widget loads,
registers and renders, and its field posts exactly one value; a field
whose widget 404s keeps its text input and still posts its value.

Not addressed: loadPluginWidgetsFromManifest still has no caller. The
per-field ensureWidget path is lazier and is what the form now uses, so
that bulk helper is dead weight -- worth removing, but left alone here
rather than inventing a call site for it.

Known limitation, documented: only string-typed fields take this path.
object/array/boolean/number fields and enums are dispatched by the
template's own branches, which still only know core widgets.

LED Matrix Web Interface V3

Modern, production web interface for controlling the LED Matrix display.

Overview

This directory contains the active V3 web interface with the following features:

  • Real-time display preview via Server-Sent Events (SSE)
  • Plugin management and configuration
  • System monitoring and logs
  • Modern, responsive UI
  • RESTful API

Running the Web Interface

Standalone (Development)

From the project root:

python3 web_interface/start.py

Or using the shell script:

./web_interface/run.sh

As a Service (Production)

The web interface can run as a systemd service that starts automatically based on the web_display_autostart configuration setting:

sudo systemctl start ledmatrix-web
sudo systemctl enable ledmatrix-web  # Start on boot

Accessing the Interface

Once running, access the web interface at:

Configuration

The web interface reads configuration from:

  • config/config.json - Main configuration
  • config/config_secrets.json - API keys and secrets

API Documentation

The V3 API is mounted at /api/v3/ (app.py:144). For the complete list and request/response formats, see docs/REST_API_REFERENCE.md. Quick reference for the most common endpoints:

Configuration

  • GET /api/v3/config/main - Get main configuration
  • POST /api/v3/config/main - Save main configuration
  • GET /api/v3/config/secrets - Get secrets configuration
  • POST /api/v3/config/raw/main - Save raw main config (Config Editor)
  • POST /api/v3/config/raw/secrets - Save raw secrets

Display & System Control

  • GET /api/v3/system/status - System status
  • POST /api/v3/system/action - Control display (action body: start_display, stop_display, restart_display_service, restart_web_service, git_pull, reboot_system, shutdown_system, enable_autostart, disable_autostart)
  • GET /api/v3/display/current - Current display frame
  • GET /api/v3/display/on-demand/status - On-demand status
  • POST /api/v3/display/on-demand/start - Trigger on-demand display
  • POST /api/v3/display/on-demand/stop - Clear on-demand

Plugins

  • GET /api/v3/plugins/installed - List installed plugins
  • GET /api/v3/plugins/config?plugin_id=<id> - Get plugin config
  • POST /api/v3/plugins/config - Update plugin configuration
  • GET /api/v3/plugins/schema?plugin_id=<id> - Get plugin schema
  • POST /api/v3/plugins/toggle - Enable/disable plugin
  • POST /api/v3/plugins/install - Install from registry
  • POST /api/v3/plugins/install-from-url - Install from GitHub URL
  • POST /api/v3/plugins/uninstall - Uninstall plugin
  • POST /api/v3/plugins/update - Update plugin

Plugin Store

  • GET /api/v3/plugins/store/list - List available registry plugins
  • GET /api/v3/plugins/store/github-status - GitHub authentication status
  • POST /api/v3/plugins/store/refresh - Refresh registry from GitHub

Real-time Streams (SSE)

SSE stream endpoints are defined directly on the Flask app (app.py:607-619 — includes the CSRF exemption and rate-limit hookup alongside the three route definitions), not on the api_v3 blueprint:

  • GET /api/v3/stream/stats - System statistics stream
  • GET /api/v3/stream/display - Display preview stream
  • GET /api/v3/stream/logs - Service logs stream

Development

When making changes to the web interface:

  1. Edit files in this directory
  2. Test changes by running python3 web_interface/start.py
  3. Restart the service if running: sudo systemctl restart ledmatrix-web

Notes

  • Templates and static files use the v3/ prefix to allow for future versions
  • The interface uses Flask blueprints for modular organization
  • SSE streams provide real-time updates without polling
