Exactly this. Create React App is awesome except its not TypeScript, and unfortunately the key point of Create Reacte App is that it is opinionated which is its magnificent strength, but it's opinion is not TypeScript as the primary language choice. It's a pity TypeScript isn't the default.

I'd list Create React App as the number one best JavaScript technology of all time, awarded for the massive pain saving it confers. It allows the most fabulous thing in the world, which is to avoid using the JavaScript tooling.
