Upgrading typescript version (question)

[lidermanrony]

How can i update the typescript version?
I have a dependency library (mobx) whose d.ts file uses a 2.7-only feature (unique symbol).
This causes my project to not compile.

You should have no trouble doing that. Personally I'm on an old version of [email protected], but with the latest [email protected].
Furthermore, the latest react-scripts-ts actually declares [email protected] as devDependency and typescript@2 as peerDependency.

create-react-app-typescript/packages/react-scripts/package.json

Lines 65 to 68 in e4b1f94

	"typescript": "^2.7.1"
	},
	"peerDependencies": {
	"typescript": "2.x"

Do I need to eject to do this upgrade? I don't see any reference to typescript version in my app.
