I had difficulty finding a clear boilerplate for using Typescript with React, so I created a project on github that goes through the steps required to setup a basic project:

https://github.com/toldsoftware/boilerplate-react-typescript

It has the following features:

• React
• Typescript
• Webpack
• Browsersync
• Example Components
  • Simple
  • With Function Body
  • With Logic
  • Warning on Text
  • With Children
  • With State
