Create a new Next.js Typescript web app on macOS

next-typescript-macos.md

Make sure you have Node.js installed either from the nodejs.org page or via HomeBrew (brew install node).

You’ll also need yarn set up in order to run this code. You can get yarn with:

npm install -g yarn

Create a new Next.js app (it will prompt for a name)

yarn create next-app --typescript

Open your directory and run the server! (replace my-app with whatever you named your app)

cd my-app
yarn dev
open http://localhost:3000

Also using VSCode for Typescript development is great (probably because VSCode itself is written in Typescript)
