Starting from [email protected] or higher, there is a built-in support for typescript. i.e, create-react-app now supports typescript natively. You can just pass --typescript option as below

npx create-react-app my-app --typescript

# or

yarn create react-app my-app --typescript

But for lower versions of react scripts, just supply --scripts-version option as react-scripts-ts while you create a new project. react-scripts-ts is a set of adjustments to take the standard create-react-app project pipeline and bring TypeScript into the mix.

Now the project layout should look like the following:


+- .gitignore

+- images.d.ts

+- node_modules/

+- public/

+- src/

¦  +- ...

+- package.json

+- tsconfig.json


+- tsconfig.test.json

+- tslint.json
