JobNotifier

Polls GitHub repos tracking Canadian tech internships and sends new postings to Discord.

Monitored Repos

• negarprh/Canadian-Tech-Internships-2026
• hanzili/canada_sde_intern_position

Setup

npm install
cp .env.example .env
# Add your Discord webhook URL to .env

Usage

# Seed state (skip initial flood of notifications)
npm start -- --seed

# Run the notifier (polls every 15 min)
npm run dev        # local (loads .env)
npm start          # cloud (env vars injected)

Deploy (Vercel)

1. Deploy the repo with the /api/worker cron function and vercel.json schedule.
2. Set DISCORD_WEBHOOK_URL, CRON_SECRET, UPSTASH_REDIS_REST_URL, and UPSTASH_REDIS_REST_TOKEN in Vercel.
3. Keep GITHUB_TOKEN optional for higher GitHub rate limits.
4. First cron run seeds state silently and sends no initial Discord flood.
5. POLL_INTERVAL_MINUTES only applies to local long-running mode; Vercel cadence comes from vercel.json.

Validation:

npm run smoke:worker
npm test
npm run typecheck
npm run build
DISCORD_WEBHOOK_URL=https://discord.invalid CRON_SECRET=test-secret UPSTASH_REDIS_REST_URL=https://example.com UPSTASH_REDIS_REST_TOKEN=test-token npx vercel build --yes
