# frontend-pr-screenshot
Posts a live screenshot of the frontend chat app to the active GitHub PR.
## Workflow
### 1 — Verify open PR
```bash
PR_NUMBER=$(gh pr view --json number -q '.number' 2>/dev/null)
# If this fails, tell the user to open a PR first and stop.
```
### 2 — Ensure dev server on port 3000
```bash
if ! lsof -ti:3000 > /dev/null 2>&1; then
cd frontend && pnpm run dev &
DEV_PID=$!
READY=0
for i in $(seq 1 30); do
curl -sf http://localhost:3000 > /dev/null 2>&1 && READY=1 && break
sleep 1
done
[ "$READY" -eq 0 ] && echo "Dev server unreachable after 30 s" && exit 1
fi
```
### 3 — Screenshot with Playwright
The app defaults to dark mode when no OS preference is detected.
Pass `--color-scheme dark` so headless Chromium matches.
```bash
cd frontend && npx playwright screenshot \
"http://localhost:3000/chat" \
/tmp/frontend-screenshot.png \
--wait-for-selector "#message-input" \
--color-scheme dark \
--timeout 15000
```
Install if missing: `pnpm exec playwright install chromium --with-deps`
### 4 — Post PR comment
`gh pr comment --attach` (gh ≥ 2.99.0) uploads the local file and rewrites the
matching Markdown reference in place, so no release asset or public URL is
needed. Do NOT commit screenshots to the repo (`.github/pr-assets/` is
gitignored).
```bash
DATE_UTC=$(date -u '+%Y-%m-%d %H:%M UTC')
gh pr comment "$PR_NUMBER" \
--attach '/tmp/frontend-screenshot.png#App screenshot' \
--body "$(cat <<EOF
## Frontend Screenshot
> Captured from /chat — ${DATE_UTC}
EOF
)"
```
### 5 — Clean up
If you started the dev server in step 2:
```bash
[ -n "$DEV_PID" ] && kill "$DEV_PID" 2>/dev/null || true
```
