react router dom v6 types - i have not tested this in all cases, nor have i ensured this covers the full api, - this should just be a nice drop in single .d.ts file that covers basic usecases detailed in https://dev.to/emreloper/react-router-v6-in-two-minutes-2i96, including inlining the necessary types for history and react-router

thanks @huy-ta, updated. mystical-ryan, you need to get navigate from useNavigate. unfortunately i wont be providing support for react router here - the focus is solely sharing types for super early adopters

Oh. apologies for the unclear question. according to the documentation, I can do navigate(-1), but I can't because typescript is complaining that -1 is not assignable to parameter of type 'string'. how do I update the .d.ts file that you have provided to overcome that? I am still new to typescript.

Thanks in adv

ah i see. i didnt know that :) try

  type navigateFn = (to: string | number, args?: { replace?: boolean, state?: object }) => void
  export function useNavigate(): (to: string, options?: Omit<NavigateProps<T>, 'to'>) => navigateFn;

i have updated the gist accordingly

thanks! think also need to include string | number in the following places:

export function useNavigate(): (to: string | number, options?: Omit<NavigateProps<T>, 'to'>) => navigateFn;
type NavigateProps<T> = {
    to: string | number,
    replace?: boolean,
    state?: T
  }

according to the new major changes here https://github.com/ReactTraining/react-router/releases/tag/v6.0.0-alpha.3 .. redirect was removed FYI

thanks @cdaz5 i removed it (i backed up v6.0.0-alpha2 typings here) and also added export function useSearchParams(): URLSearchParams

thanks! think also need to include string | number in the following places:

export function useNavigate(): (to: string | number, options?: Omit<NavigateProps<T>, 'to'>) => navigateFn;
type NavigateProps<T> = {
    to: string | number,
    replace?: boolean,
    state?: T
  }

right in order to support navigate(-1) instead of goBack()
remix-run/react-router#7159 (comment)

ah thanks @gitpash

export function useNavigate(T = object): (to: string | number, options?: Omit<NavigateProps<T>, 'to'>) => navigateFn; do you mean T = Object?

tbh i havent really tested that code (since my project doesnt need it) - can we do better than Object? what should we really be putting there?

tbh i havent really tested that code (since my project doesnt need it) - can we do better than Object? what should we really be putting there?

Was looking at it more closely

export function useNavigate(T = object): (to: string | number, options?: Omit<NavigateProps<T>, 'to'>) => navigateFn;
  type NavigateOptions<T> = Omit<NavigateProps<T>, 'to'>
  type NavigateProps<T> = {
    to: string | number,
    replace?: boolean,
    state?: T
  }

not sure why passing T = Object as a prop to useNavigate (I'm not familiar with such pattern)
in my perspective main reason is to explicitly describe the shape of state prop in NavigateProps, if so

export function useNavigate<T>(): (to: string | number, options?: Omit<NavigateProps<T>, 'to'>) => navigateFn; - should be enough
but for more accuracy in order to define object like shape (to prevent smth like useNavigate<string>) we can use Metaobject

interface MetadataObj {
    [key: string]: any;
  }
  export function useNavigate<T extends MetadataObj>(): (
    to: string | number,
    options?: Omit<NavigateProps<T>, 'to'>
  ) => navigateFn;

this seems to be ok in my project

not sure why passing T = Object as a prop to useNavigate (I'm not familiar with such pattern)

that was a typo. I meant to write useNavigate<T = Object> instead - basically saying i declare a generic type T, and if the user doesnt give me anything, i'll just give it a default of Object.

ok i hear you - thats good enough for me to work with. i'll fix it up, cheers

thank you! really appreciate your work here and in other projects 👍 I'm happy if I can help in any way

there is finally an attempt to update types on definitelytyped - see @murbanowicz's work here DefinitelyTyped/DefinitelyTyped#44015

i dont intend to maintain typings here much longer as i dont currently actively use RR

I will appreciate any help with moving it forward! @gitpash
