BJKW Weather Proxy

Cloudflare Worker proxy for bjkw_weather.html.

The browser calls this Worker without a CWA API key. The Worker reads CWA_API_KEY from Cloudflare secrets, adds it to the upstream Central Weather Administration Open Data request, and returns JSON to the GitHub Pages weather dashboard.

Why

• No API key in GitHub Pages HTML.
• No need to type the key on every device.
• CORS is limited to https://blackjw1212.github.io.
• The proxy only allows the weather endpoints used by the page.
• Successful upstream responses are cached at the Worker for 60 seconds.

Local setup

cd weather-proxy
npx wrangler login
npx wrangler secret put CWA_API_KEY
npx wrangler deploy

The public URL should be:

https://bjkw-weather-proxy.blackjw1212.workers.dev

If a different Worker URL is used, update WEATHER_PROXY_BASE in ../bjkw_weather.html.

Required GitHub Actions secrets

To deploy from GitHub Actions, add these repository secrets:

• CLOUDFLARE_API_TOKEN
• CLOUDFLARE_ACCOUNT_ID
• CWA_API_KEY

The workflow intentionally skips deployment if those secrets are absent.
