[Josehower]

Add new with router typescript example based on suggestions #412 (comment)

[siarheipashkevich]

why do we need it?

[karlhorky]

"resolutions" and "overrides" are in the original package.json from with-router as well:

examples/with-router/package.json

Lines 25 to 32 in bd68019

	"resolutions": {
	"metro": "^0.73.7",
	"metro-resolver": "^0.73.7"
	},
	"overrides": {
	"metro": "^0.73.7",
	"metro-resolver": "^0.73.7"
	},

probably some compatibility thing

Is there any point in this when npx create-expo-app -t offers a typescript with router option, that also has a tab bar and a few example screens?

I will say I would greatly appreciate this PR. I love expo-router, and have been having issues trying to implement TypeScript after spinning up npx create-expo-app@latest --example with-router. This would help me a ton!

I already created the application and installed the TS even before starting to use expo-router, is there a way to type the routes?

is there a way to type the routes?

There is a discussion about typed props of a route here (originally an issue, but converted into a discussion):
