Documentation related question

In this page https://refine.dev/docs/routing/integrations/remix/#usage, app/routes/posts._index.tsx here in the code ,

import { useTable } from "@refinedev/core";
// see no imports mentioned
import { NavLink } from "@remix-run/react";

import { useTable } from "@refinedev/core";
// see no imports mentioned
import { NavLink } from "@remix-run/react";

from where is the useGetToPath is being imported from ? In my code when I paste it it wants me to import useGettoPath.

import { useGetToPath, useTable } from "@refinedev/core";
// see the import above

import { useGetToPath, useTable } from "@refinedev/core";
// see the import above

but when I do, in this section this error happens Type 'string | undefined' is not assignable to type 'To'.ts(2322)

              <NavLink
                to={getToPath({
                  resource: "categories",
                  action: "show",
                  meta: { id: category.id },
                })}
              >
                {post.title}
              </NavLink>

              <NavLink
                to={getToPath({
                  resource: "categories",
                  action: "show",
                  meta: { id: category.id },
                })}
              >
                {post.title}
              </NavLink>

again in categories._index.tsx in the docs , getToPath has been imported but no useGetToPath. in this line const getToPath = useGetToPath(); there is another getToPath that's coming from useGetToPath(). in the <NavLink/> Type 'string | undefined' is not assignable to type 'To'.ts(2322) this error happens again.

Hi @toxi_teemo. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- The useGetToPath hook is indeed missing from the import statement in the provided code snippets from the Remix integration documentation (https://refine.dev/docs/routing/integrations/remix#usage). It should be imported from @refinedev/core as you've correctly done in your code. The error Type 'string | undefined' is not assignable to type 'To'.ts(2322) you're encountering is likely due to the fact that the getToPath function can potentially return undefined, which is not a valid type for the to prop in the NavLink component. To fix this, you can add a check to ensure that getToPath does indeed return a string before passing it to NavLink. Here's how you can do it:

const toPath = getToPath({
  resource: "categories",
  action: "show",
  meta: { id: category.id },
});

if (typeof toPath === "string") {
  return (
    <NavLink to={toPath}>
      {post.title}
    </NavLink>
  );
}

const toPath = getToPath({
  resource: "categories",
  action: "show",
  meta: { id: category.id },
});

if (typeof toPath === "string") {
  return (
    <NavLink to={toPath}>
      {post.title}
    </NavLink>
  );
}

This way, the NavLink component will only be rendered if getToPath returns a string. If it returns undefined, the NavLink component will not be rendered, thus avoiding the TypeScript error. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Type 'string' is not assignable to type 'IResourceItem' , in the resource key.

Let me check the knowledge base for you. One moment! :books: ---------------------- The error Type 'string' is not assignable to type 'IResourceItem' typically occurs when you're trying to assign a string value to a variable or property that is expected to be of type IResourceItem. The IResourceItem is an interface used in Refine to describe a resource. It has properties like name, list, create, edit, show, etc. as described in the useResource API Reference (https://refine.dev/docs/routing/hooks/use-resource#interfaces). Here's how the IResourceItem interface is defined:

interface IResourceComponents {  
 list?: string | React.ComponentType<any> | { component: React.ComponentType<any>; path: string };  
 create?: string | React.ComponentType<any> | { component: React.ComponentType<any>; path: string };  
 edit?: string | React.ComponentType<any> | { component: React.ComponentType<any>; path: string };  
 show?: string | React.ComponentType<any> | { component: React.ComponentType<any>; path: string };  
}  
  
interface IResourceItem extends IResourceComponents {  
 name: string;  
 identifier?: string;  
 meta?: MetaProps;  
}

interface IResourceComponents {  
 list?: string | React.ComponentType<any> | { component: React.ComponentType<any>; path: string };  
 create?: string | React.ComponentType<any> | { component: React.ComponentType<any>; path: string };  
 edit?: string | React.ComponentType<any> | { component: React.ComponentType<any>; path: string };  
 show?: string | React.ComponentType<any> | { component: React.ComponentType<any>; path: string };  
}  
  
interface IResourceItem extends IResourceComponents {  
 name: string;  
 identifier?: string;  
 meta?: MetaProps;  
}

If you're trying to assign a string to a property that expects an IResourceItem, you should instead create an object that adheres to the IResourceItem interface. For example:

const resource: IResourceItem = {
  name: "myResource",
  list: "myListComponent",
  create: "myCreateComponent",
  edit: "myEditComponent",
  show: "myShowComponent",
};

const resource: IResourceItem = {
  name: "myResource",
  list: "myListComponent",
  create: "myCreateComponent",
  edit: "myEditComponent",
  show: "myShowComponent",
};

If you're seeing this error in the context of the getToPath function, it's likely because you're passing a string as the resource parameter, when it should be an IResourceItem. The getToPath function expects its parameters to be of type UseToPathParams, which is defined as follows:

type UseToPathParams = {
  resource: IResourceItem;
  action: "list" | "create" | "edit" | "show" | "clone";
  meta?: {
    id?: BaseKey;
    [key: string]: unknown;
  };
};

type UseToPathParams = {
  resource: IResourceItem;
  action: "list" | "create" | "edit" | "show" | "clone";
  meta?: {
    id?: BaseKey;
    [key: string]: unknown;
  };
};

So, when calling getToPath, make sure to pass an IResourceItem as the resource parameter, like so:

getToPath({
  resource: myResource, // This should be an IResourceItem, not a string
  action: "list",
  meta: {
    id: 1,
  },
});

getToPath({
  resource: myResource, // This should be an IResourceItem, not a string
  action: "list",
  meta: {
    id: 1,
  },
});

If you're still having trouble, please provide more context or a code snippet so I can give a more accurate answer. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Hello @toxi_teemo , Yes getToPath is should be imported from @refinedev/core, we will fix the documentation. Error is legit because getToPath can be return undefined if no resource found. You can "null" check your returning value.
