Claude 324a7eac87 fix(web): style editor no longer strands leaf-valued layout fields
A prior fix on this PR made elementKeys() append any layout-only key with
no style block of its own (a logo, a timeout indicator, a possession
arrow), so table() draws a row for it instead of losing it when the
wholesale `layout` claim removes the generic fallback. That covers a
layout-only key shaped like an object (x_offset/y_offset, ...), because
columnsFor() only ever produced columns from a key's *sub-fields*.

It missed the case where the layout-only key's own value is itself a
leaf -- a plain "show_logo" boolean directly under layout, no x/y object
underneath. elementKeys() still lists it (any row: no matching column),
so it renders as an uneditable blank row and its only control -- the
generic fallback checkbox -- is still gone. Confirmed by executing the
real widget's render() against a synthetic schema in Node (a DOM-stub
harness, not committed): the field's name never appeared as an <input>.

columnsFor() now gives such a leaf key a column keyed to itself
('layout-leaf'), and elementRow() binds it to the leaf's own path
(customization.layout.<key>, matching the name the fallback would have
used) instead of leaving every cell blank.

New regression test (test/js/unit/test_style_editor_layout_leaf_columns.js,
following this PR's existing eval-extraction pattern) checks the leaf
column is produced, is self-keyed, doesn't duplicate, and that a schema
with no leaf-valued layout key is unaffected; wired into run_all.js and
the suite table in test/js/README.md.

test/js/run_all.js: 84 + 6 + 6 = all suites passed (jsdom unavailable
here, DOM suites skip as before). Python suite untouched by this change;
test_style_editor_extra_fields.py, test_style_editor_save_roundtrip.py
and the one PIL-dependent style_editor_takeover.py case fail identically
before this commit -- missing flask/PIL in this sandbox, not this PR.

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
