Gatsby supports TypeScript by default!

This means that you can create and write .ts/.tsx files for your pages, components etc. Please note that the gatsby-*.js files (like gatsby-node.js) currently don't support TypeScript yet.

For type checking you'll want to install typescript via npm and run tsc --init to create a .tsconfig file.
