David Wells & Chris Coyier talk about how you can build an app hosted on Netlify statically but still have a backend database to power it. We use the classic TODO app example where the database is powered by FaunaDB and we talk to that database via serverless functions (i.e. Node.js JavaScript functions running on AWS Lambda via Netlify’s extremely easy and powerful integration). Put the JavaScript files in a /functions folder and they’ll be deployed and runnable!
