Summary
Polish Collabify for “team-ready” deployments by tightening auth, adding API guardrails, indexing Mongo, finishing i18n coverage, and smoothing CI/release flows. This is intentionally a bundle of small, safe changes that deliver outsized stability and UX wins.
Scope & Tasks
1) Auth0 & API guardrails
Next.js middleware sketch
// middleware.ts
import { NextResponse } from "next/server";
import { jwtVerify } from "jose";
const ISSUER = process.env.AUTH0_ISSUER_BASE_URL!;
const AUD = process.env.AUTH0_AUDIENCE!;
export async function middleware(req: Request) {
const url = new URL(req.url);
if (!url.pathname.startsWith("/api")) return NextResponse.next();
const token = req.headers.get("authorization")?.replace(/^Bearer\s+/i, "");
if (!token) return NextResponse.json({ error: "Unauthorized" }, { status: 401 });
try {
const { payload } = await jwtVerify(token, /* your JWKS or secret */, {
issuer: `${ISSUER}/`,
audience: AUD,
});
// Optional: role checks
const roles = (payload["https://collabify/roles"] as string[]) ?? [];
(req as any).auth = { sub: payload.sub, roles };
return NextResponse.next();
} catch {
return NextResponse.json({ error: "Invalid token" }, { status: 401 });
}
}Route guard example
// pages/api/admin/roles.ts
export default async function handler(req, res) {
const roles: string[] = req?.auth?.roles ?? [];
if (!roles.includes("admin")) return res.status(403).json({ error: "Forbidden" });
// ...
}Rate limit (simple token bucket)
// lib/rate-limit.ts
const buckets = new Map<string, { tokens: number; ts: number }>();
export function allow(key: string, rate=10, perMs=10_000) {
const now = Date.now();
const b = buckets.get(key) ?? { tokens: rate, ts: now };
const refill = Math.floor(((now - b.ts) / perMs) * rate);
b.tokens = Math.min(rate, b.tokens + refill);
b.ts = now;
if (b.tokens <= 0) return false;
b.tokens -= 1; buckets.set(key, b); return true;
}2) MongoDB indexes & data hygiene
Index examples (Mongoose)
// models/Task.ts
TaskSchema.index({ projectId: 1, createdAt: -1 });
TaskSchema.index({ assignees: 1, status: 1 });
TaskSchema.index({ title: "text", description: "text" }); // search3) i18n coverage & language switch UX
4) Accessibility & keyboard flows
5) Performance & UX
6) Logging & error handling
7) CI/CD & release hygiene
Action snippet
# .github/workflows/ci.yml
name: CI
on: [push, pull_request]
jobs:
web:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: actions/setup-node@v4
with: { node-version: 20, cache: npm }
- run: npm ci
- run: npm run typecheck
- run: npm run lint
- run: npm test -- --ci
- run: npm run build8) Docker & env consistency
Acceptance Criteria
- ✅ All protected API routes reject invalid/expired tokens; admin endpoints require
admin role.
- ✅ P95 API latencies improved via indexes (document the before/after on
/api/projects & /api/projects/[id]/tasks).
- ✅ i18n keys complete for EN & VI; language switch persists;
<html lang> updates.
- ✅ Lighthouse a11y score ≥ 95 on Dashboard & Project pages.
- ✅ CI green on PRs; build artifacts reproducible; preview deploy comments appear.
- ✅ Docker image runs with non-root user and minimal attack surface.
- ✅ Error responses are consistent and include a
traceId.
Nice-to-have (future)
- Global search with Mongo Atlas Search (fuzzy) or Meilisearch.
- Webhooks for project events; Slack/Email notifications.
- Task activity feed with server-sent events.
- Usage analytics (privacy-aware) and feature flags.
