Navigating with Typescript in Expo using the 'router.push' method

When working with Expo and TypeScript, I often use paths like this:

const [HomePath , SettingsPath, ProfilePath]  = [
  "/",
  "/settings",
  "/profile",
];

router.push(HomePath);

Recently, I encountered the following error: 

"Argument of type 'string' is not assignable to parameter of type 'Href<string | object>'",

I attempted a solution by defining HomePath as follows:

const HomePath : Href<string | object> = '/';

While this fixed the type error, it feels a bit convoluted. Is there a simpler way to address this issue? Any suggestions would be greatly appreciated! Thanks!

Answer №1

To ensure TypeScript compatibility, simply convert all your paths to Href<string>

const [HomePagePath, SettingsPagePath, ProfilePagePath]  = [
  "/home",
  "/settings",
  "/profile",
] as Href<string>;

Answer №2

In the past, I stored my routes in a separate constant file too. However, it appears that the expo router now takes care of type checking all available routes for us.

Simply call router.push("/")

If the route is not found, an error will be raised

Answer №3

It may seem trivial, but I encountered a similar problem and was able to resolve it by simply restarting my expo app. It turns out that I was making changes to the paths while the app was still running.
