# Phase 01 Plan 04: Device CRUD UI and CSS Variable Fix Summary
|
||||
|
||||
**Gap-closure plan: added device add/remove form to DEVICES panel and fixed CSS variable naming — closes DEV-03 (device list with UI interaction) and UI-02 (CSS contract alignment)**
|
||||
|
||||
## Performance
|
||||
|
||||
- **Duration:** ~2 min
|
||||
- **Started:** 2026-04-05T20:11:51Z
|
||||
- **Completed:** 2026-04-05T20:13:30Z
|
||||
- **Tasks:** 2 (both auto)
|
||||
- **Files modified:** 3 (index.html, app.js, style.css)
|
||||
|
||||
## Accomplishments
|
||||
|
||||
### Task 1: Device CRUD UI
|
||||
|
||||
- Added `<form id="add-device-form" class="device-form">` to the DEVICES panel in `index.html`, with inputs for name (text), strip_type (select: sk6812/ws2801/generic), led_count (number), ip (text), port (number, default 21324), and a submit button "+ ADD DEVICE"
|
||||
- Added `apiPost(path, data)` and `apiDelete(path)` async fetch helpers to `app.js` (positioned after WS_URL const, before LightSyncClient)
|
||||
- Updated `loadDevices()` device row template to include a `.device-remove` button with `onclick="removeDevice(d.id)"` alongside a `.device-row-info` wrapper for the name/metadata
|
||||
- Added `removeDevice(id)` function that calls `apiDelete(/api/devices/{id})` then refreshes the list; exported as `window.removeDevice` for ES module compatibility with inline onclick handlers
|
||||
- Added form submit handler that calls `apiPost("/api/devices", data)`, resets form (restoring port default to 21324), then refreshes the device list
|
||||
- Added panel IDs to all four panels: `id="devices-panel"`, `id="animations-panel"`, `id="timeline-panel"`, `id="transport-panel"`
|
||||
|
||||
### Task 2: CSS Variable Naming Fix
|
||||
|
||||
- Added `--accent: #00ffff` as canonical variable in `:root`
|
||||
- Changed `--border-bright` and `--text-accent` to be aliases: `var(--accent)` instead of hardcoded `#00ffff`
|
||||
- Added `.device-form` CSS rule: flex-column, 4px gap, border-top separator from device list
|
||||
- Added `.device-remove` rule: borderless button, dim text, hover turns red (`#ff3333`)
|
||||
- Updated `.device-row` to `display: flex; align-items: center; justify-content: space-between` to accommodate remove button alongside info
|
||||
- Added `.device-row-info` flex-column wrapper for name + metadata within each row
|
||||
|
||||
## Task Commits
|
||||
|
||||
1. **Task 1: Device CRUD UI** — `ccc40c8` (feat)
|
||||
2. **Task 2: CSS variable fix + device form styles** — `2ff35f9` (feat)
|
||||
|
||||
## Files Created/Modified
|
||||
|
||||
- `lightsync/frontend/index.html` — added form, panel IDs, timeline/transport panel wrappers
|
||||
- `lightsync/frontend/app.js` — added apiPost, apiDelete, removeDevice, form submit handler, updated device row template
|
||||
- `lightsync/frontend/style.css` — added --accent canonical variable, aliases, device form and remove button styles
|
||||
|
||||
## Decisions Made
|
||||
|
||||
- **Panel IDs added in Task 1**: The HTML file was already being modified for the form, so panel IDs were added in the same edit pass to minimize diff noise. Task 2 only touched CSS.
|
||||
- **window.removeDevice export**: ES modules scope all declarations — `onclick="removeDevice(...)"` in dynamically rendered HTML requires the function to be on the global `window` object.
|
||||
- **No refactor of --text-accent usage sites**: `--border-bright` and `--text-accent` are now aliases of `--accent`. No existing CSS rules using these variables needed to change — the alias pattern lets the semantics remain meaningful (text-accent vs border-bright) while sharing a single source color value.
|
||||
|
||||
## Deviations from Plan
|
||||
|
||||
None — plan executed exactly as written. Panel IDs were added in Task 1 edit rather than Task 2 (minor sequencing optimization, not a behavioral change).
|
||||
|
||||
## Requirements Closed
|
||||
|
||||
| Requirement | Status | Evidence |
|
||||
|-------------|--------|----------|
|
||||
| DEV-03 | CLOSED | Add-device form in DEVICES panel; POST/DELETE wired; device rows have remove buttons |
|
||||
| UI-02 | CLOSED | `--accent: #00ffff` canonical variable present; `--text-accent` and `--border-bright` are aliases; all four panel IDs present |
|
||||
|
||||
## Verification Results
|
||||
|
||||
1. `grep "add-device-form" lightsync/frontend/index.html` — MATCH
|
||||
2. `grep "apiPost\|apiDelete\|removeDevice" lightsync/frontend/app.js` — 4 matches (function defs + window export + apiPost call in form handler)
|
||||
3. `grep "\-\-accent.*#00ffff" lightsync/frontend/style.css` — MATCH
|
||||
4. `grep "devices-panel\|animations-panel\|timeline-panel\|transport-panel" lightsync/frontend/index.html` — 4 matches
|
||||
|
||||
## Known Stubs
|
||||
|
||||
None — all gap-closure work is fully wired. The form submits to a live API endpoint. Device removal calls a live DELETE endpoint.
