- Fetches top Hacker News articles periodically.
- Generates summaries and scripts using AI.
- Converts text to audio using TTS. Thanks to Minimax Audio for sponsoring the TTS service.
- Stores data 8000 in Cloudflare R2 and KV.
- Provides access via RSS feed and web interface.
The project consists of a Worker and a Web application. The Worker is responsible for fetching data and processing audio, utilizing Cloudflare R2, KV, Workers AI, and Browser Rendering. The Web application displays data and provides the RSS feed. It's built with Next.js and uses the OpenNext Cloudflare adapter.
- Install dependencies:
pnpm install- Configure environment variables:
Create .dev.vars for the web app and worker/.dev.vars for the worker:
# .dev.vars
NEXTJS_ENV=development
NEXT_STATIC_HOST=http://localhost:3000/static
# worker/.dev.vars
WORKER_ENV=development
HACKER_PODCAST_WORKER_URL=http://localhost:8787 # Your worker URL for local dev
HACKER_PODCAST_R2_BUCKET_URL= # Local R2 bucket URL (if using Miniflare or similar)
OPENAI_API_KEY=your_api_key
OPENAI_BASE_URL=https://api.openai.com/v1 # Optional: Change if using a proxy
OPENAI_MODEL=gpt-4-turbo # Or your preferred model- Start the development servers:
# Start the Worker (fetches data, processes audio)
pnpm dev:worker
# To manually trigger the worker: curl -X POST http://localhost:8787
# Start the Web app (frontend)
pnpm devNotes:
- When running the worker locally, Edge TTS audio conversion might stall. It's recommended to comment out this part during debugging if issues arise.
- Audio merging relies on Cloudflare's Browser Rendering API, which is not available locally. Remote debugging or testing is required for this feature. You can potentially use
pnpm run testfor related tests (check test setup).
This project is deployed using Cloudflare Workers:
- Create an R2 bucket. After binding a custom domain, update the
NEXT_STATIC_HOSTandHACKER_PODCAST_R2_BUCKET_URLvariables in your Cloudflare dashboard secrets and potentiallywrangler.toml. - Create a KV namespace.
- Update the KV namespace ID and R2 bucket name in
wrangler.toml. - Configure environment variables and secrets using the
wranglerCLI:
# Set secrets for the Worker
pnpx wrangler secret put --cwd worker HACKER_PODCAST_WORKER_URL # Use your deployed worker URL
pnpx wrangler secret put --cwd worker HACKER_PODCAST_R2_BUCKET_URL # Use your R2 public bucket URL
pnpx wrangler secret put --cwd worker OPENAI_API_KEY
pnpx wrangler secret put --cwd worker OPENAI_BASE_URL # Optional
pnpx wrangler secret put --cwd worker OPENAI_MODEL # Optional
# Set secrets for the Web application (Next.js on Cloudflare Pages/Workers)
pnpx wrangler secret put NEXTJS_ENV
# Ensure NEXT_STATIC_HOST is set in the Pages deployment settings or via wrangler secret put if deploying manually
pnpx wrangler secret put NEXT_STATIC_HOST # Use your R2 public bucket URL (same as HACKER_PODCAST_R2_BUCKET_URL)Deploy the applications:
# Make sure to uncomment the workflows configuration in wrangler.toml if needed
pnpm deploy:worker
pnpm deploy # Deploys the Next.js app via OpenNext adapterIssues and Pull Requests are welcome!
