Type systems like TypeScript are the next thing when developing JavaScript applications. They make sure that your props are passed in the correct form and shape throughout your application. Together with GraphQL's query language based on types, you can create the web application of the future! This talk will show you how to leverage the TypeScript type system to help you create a type safe application, all based on your data coming from GraphQL. If you're working with React and either TypeScript or GraphQL, you'll definitely want to combine them afterwards.
