Nowcasting Alerts

Prototype for a Nowcasting Alerts service. We use a Cloudflare Workers cron to fetch the most recent Nowcasting and PV_Live forecasts, and check if there's a deviation in values (currently hard coded to 0.5GW). If there is, we make a POST request to all configured alert URLs.

This app is built with Remix and deployed to Cloudflare Pages.

There is a sister repo

Development

You will be utilizing Wrangler for local development to emulate the Cloudflare runtime. This is already wired up in your package.json as the dev script:

# start the remix dev server and wrangler
npm run dev

Open up http://127.0.0.1:8788 and you should be ready to go!

Deployment

Cloudflare Pages are currently only deployable through their Git provider integrations.

If you don't already have an account, then create a Cloudflare account here and after verifying your email address with Cloudflare, go to your dashboard and follow the Cloudflare Pages deployment guide.

Create a new Cloudflare Pages project, connect this repo. Set framework to Remix. Set env var NODE_VERSION = v16.7.0
