* feat(ui): add reusable json-file-manager widget for plugin file management Introduces JsonFileManager — a zero-CDN, keyboard-accessible, configurable widget for managing JSON data files from plugin configuration forms. web_interface/static/v3/js/widgets/json-file-manager.js (new): - Self-contained class with scoped CSS (no global leakage) - File list with cards: enable/disable toggle, entry count, size, date - Drag-and-drop + click-to-browse JSON upload - Textarea-based JSON editor (no CDN); Format + Validate buttons - Ctrl+S to save, Escape to close any open modal - Create-new-file modal with configurable fields and validation - Delete confirmation modal - All actions (list/get/save/upload/delete/create/toggle) are configurable via x-widget-config in config_schema.json — no plugin-ID hardcoding web_interface/static/v3/plugins_manager.js: - New handler for x-widget: "json-file-manager" — renders mount div, instantiates JsonFileManager with x-widget-config and plugin ID web_interface/templates/v3/base.html: - Include json-file-manager.js (defer) before plugins_manager.js Usage: set x-widget: "json-file-manager" + x-widget-config in any plugin's config_schema.json (see ledmatrix-plugins of-the-day for a complete example). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(json-file-manager): review fixes — type=button, finally, display_name, instance tracking - Add type="button" to every button in the template (replace_all) so none default to submit inside the plugin-config-form - Wrap _doSave/_doDelete/_doCreate fetch blocks in try/finally so _idle() always fires, not only on the error path - _doCreate validation: skip the required-check for display_name (f.key !== 'display_name') and only validate pattern when val is non-empty, so the auto-derive logic at the end of the loop can run; simplify the derive block to a single conditional instead of nested DOM lookups - plugins_manager.js: track instances in window.__jfmInstances[safeFieldId] and call _destroy() on any previous instance before mounting a new one, preventing duplicate keydown handlers when the config form is re-rendered Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(json-file-manager): use validity.patternMismatch; destroy all instances on remount - Replace `new RegExp(f.pattern).test(val)` with `el.validity.patternMismatch` to avoid potential SyntaxError from untrusted pattern strings and rely on the browser's already-validated pattern attribute instead - plugins_manager.js: iterate all window.__jfmInstances and call _destroy() on every entry before mounting, then reset the map, so no orphaned keydown handlers survive when any plugin config form is re-rendered Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(plugins_manager): scope jfm instance teardown to current mount key only The global sweep (Object.values + window.__jfmInstances = {}) destroyed sibling file-manager widgets when any one of them was remounted. Replace with a targeted destroy of window.__jfmInstances[safeFieldId] only, leaving all other entries untouched. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(json-file-manager): address Codacy security warnings - Replace Math.random() with crypto.getRandomValues() for UID generation - Remove unused variable `u` in _card() - Guard this.actions property access with hasOwnProperty - Replace btn.innerHTML in _busy/_idle with DOM manipulation + textContent Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> --------- Co-authored-by: Chuck <chuck@example.com> Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>
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:
- Local: http://localhost:5000
- Network: http://:5000
Configuration
The web interface reads configuration from:
config/config.json- Main configurationconfig/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 configurationPOST /api/v3/config/main- Save main configurationGET /api/v3/config/secrets- Get secrets configurationPOST /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 statusPOST /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 frameGET /api/v3/display/on-demand/status- On-demand statusPOST /api/v3/display/on-demand/start- Trigger on-demand displayPOST /api/v3/display/on-demand/stop- Clear on-demand
Plugins
GET /api/v3/plugins/installed- List installed pluginsGET /api/v3/plugins/config?plugin_id=<id>- Get plugin configPOST /api/v3/plugins/config- Update plugin configurationGET /api/v3/plugins/schema?plugin_id=<id>- Get plugin schemaPOST /api/v3/plugins/toggle- Enable/disable pluginPOST /api/v3/plugins/install- Install from registryPOST /api/v3/plugins/install-from-url- Install from GitHub URLPOST /api/v3/plugins/uninstall- Uninstall pluginPOST /api/v3/plugins/update- Update plugin
Plugin Store
GET /api/v3/plugins/store/list- List available registry pluginsGET /api/v3/plugins/store/github-status- GitHub authentication statusPOST /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 streamGET /api/v3/stream/display- Display preview streamGET /api/v3/stream/logs- Service logs stream
Development
When making changes to the web interface:
- Edit files in this directory
- Test changes by running
python3 web_interface/start.py - 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
