# ActionTrail Web — Vercel Deployment Roadmap

> **App:** `@actiontrail/web`
> **Repo:** `learning_ai_trails` → `web/`
> **Status:** ⚠️ Partial — hardcoded standalone output

---

## Current State

- **Framework:** Next.js 16.1.6, React 19.2.3
- **Output:** ❌ Hardcoded `output: 'standalone'`
- **Styling:** No TailwindCSS (minimal CSS)
- **Dependencies:** 7 `@bytelyst/*` — **all via Gitea registry** ✅ (no `file:` refs)
- **Build:** `next build --webpack`
- **Client-side focused** — timeline, approvals, agents, insights, traces, welcome, settings
- **SSE support** — real-time toast notifications via EventSource

## Gaps to Fix

### Gap 1: Make output Vercel-aware (~5 min)

**File:** `web/next.config.ts`

```diff
- output: 'standalone',
+ ...(process.env.VERCEL ? {} : { output: 'standalone' }),
```

- [ ] Update `next.config.ts`
- [ ] Verify Docker build still works

### Gap 2: Registry Access (~5 min)

Once Gitea is deployed to the Azure VM with a public HTTPS URL, update `.npmrc`.

- [ ] Update `.npmrc` to Azure VM Gitea URL
- [ ] Set `GITEA_NPM_TOKEN` as a Vercel environment variable

### Gap 3 (optional): SSE Compatibility

Vercel serverless functions have a 25-second timeout (Hobby) / 300s (Pro). SSE streams via `GET /api/events/stream` will be cut short.

- [ ] Consider using Vercel's Edge Runtime for SSE endpoints (longer timeout)
- [ ] Or switch to polling on Vercel, keep SSE for Docker/self-hosted

## Deployment Steps

### Step 1: Fix output mode (~5 min)

### Step 2: Fix registry access (~5 min)

### Step 3: Create Vercel Project (~5 min)

- [ ] Connect `learning_ai_trails` repo
- [ ] Set **Root Directory** to `web`
- [ ] Framework preset: **Next.js**

### Step 4: Environment Variables (~5 min)

- [ ] `NEXT_PUBLIC_BACKEND_URL` — ActionTrail backend endpoint (port 4018)

### Step 5: Verify (~10 min)

- [ ] Test timeline page with action list
- [ ] Test approval queue
- [ ] Test agent card grid
- [ ] Verify SSE toast notifications work (or gracefully degrade)

### Step 6: Domain (~5 min)

- [ ] Add custom domain (e.g., `app.actiontrail.dev`)

## Estimated Total Effort: ~35 minutes
