To keep it simple and move forward, I'd like to stick with a very similar technologies structure to https://github.com/torontojs/torontojs.com. We can discuss any technology changes after MVP.
So we'll need to build out the initial folder structure for a React application. I'm not completely opposed to using create-react-app but not a fan of it either.
/
/public
/src
/src/components
/src/theme
/src/index.js
/src/App.js
We'll also need to setup a package.json, eslintrc, and some other usual files as necessary.
