Speed Task — Tasks & Rewards

This repo is intentionally small. Two tests are failing on purpose.

Quick Start

pnpm install
pnpm test

Optional (run UI + API):

pnpm dev

API: http://localhost:3000 Web: http://localhost:5173

Tasks

1) Fix: validation + status codes

Route: POST /api/users/register

Expected behavior:

• Missing telegramId -> 400
• New user -> 201
• Existing user (same telegramId) -> 200 and same user id

2) Feature: idempotent notes

Route: POST /api/notes

Expected behavior:

• title required, max 120 -> 400 when invalid
• externalId required
• First create -> 201
• Duplicate externalId -> 200 and same note id
• Concurrent requests must not create duplicates

3) Frontend

Implement a minimal UI:

• Form: externalId, title
• Show list of notes
• Show error state on failure

Rules

• Do not refactor unrelated code.
• Keep changes focused and minimal.
• Ensure idempotency behavior is covered by tests.

Submission

• Share the repo link or PR.
• If something is incomplete, say what and why.
