This is a retake on Netlify's own demo, where this one is a bit more like the setup I myself prefer and am used to. Less magic (Parcel, Create React App) and less bundles: Just plain old Express with serverless-http. Tried to get Fastify and aws-fastify-lambda working, but to no avail. Maybe will return to those later.

Uses:

• Webpack 4 with various loaders
• React 16.13
• Babel 7

Assumes that you'll use Netlify, obviously.

There's not much magic going on here. You will need to manually (un)comment the client-side or server-side mode in src/index.jsx.

Run yarn install or npm install.

• Install Netlify CLI with yarn global add netlify-cli or npm install -g netlify-cli
• Login with netlify login
• Setup Netlify project and point this code-base there

Switch to CSR mode first.

Use one of:

• netlify dev, or
• yarn start/npm run start

Switch to SSR mode and run yarn deploy or npm run deploy.
