useGo throws errors

useGo seems to throw errors if it can't find the resource. This should be handle more gracefully instead of throwing as will crash. /** * handle errors for resource * @internal */ export const handleResourceErrors = (to: Resource, resource: IResourceItem) => { if (!to?.action || !to?.resource) { throw new Error([useGo]: "action" or "resource" is required.); } if (["edit", "show", "clone"].includes(to?.action) && !to.id) { throw new Error( [useGo]: [action: ${to.action}] requires an "id" for resource [resource: ${to.resource}], ); } const actionUrl = resource[to.action]; if (!actionUrl) { throw new Error( [useGo]: [action: ${to.action}] is not defined for [resource: ${to.resource}], ); } };

Hi @Joe Gaffney. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Thank you for bringing this issue to attention. You're right that throwing errors in this case could lead to crashes, which is not ideal for a smooth user experience. Let's examine this based on the available information. The code you've shared is from an internal function handleResourceErrors used by the useGo hook. This function is designed to validate the input and ensure that all necessary information is provided before attempting navigation. While the current implementation throws errors, you're correct that a more graceful error handling approach would be beneficial. However, the knowledge sources don't provide specific information about plans to change this behavior. That said, there are a couple of ways you can work around this issue: 1. Use try-catch blocks: You can wrap your useGo calls in try-catch blocks to prevent crashes:

   try {
     go({ to: { resource: "someResource", action: "list" } });
   } catch (error) {
     console.error("Navigation error:", error);
     // Handle the error gracefully, e.g., show a user-friendly message
   }

   try {
     go({ to: { resource: "someResource", action: "list" } });
   } catch (error) {
     console.error("Navigation error:", error);
     // Handle the error gracefully, e.g., show a user-friendly message
   }

2. Check conditions before calling: You can check the necessary conditions before calling useGo:

   const { resource } = useResource();
   if (resource && resource.list) {
     go({ to: { resource: resource.name, action: "list" } });
   } else {
     console.warn("Resource or list action not available");
     // Handle the case gracefully
   }

   const { resource } = useResource();
   if (resource && resource.list) {
     go({ to: { resource: resource.name, action: "list" } });
   } else {
     console.warn("Resource or list action not available");
     // Handle the case gracefully
   }

It's worth noting that this behavior is likely designed to catch programming errors early. However, your suggestion for more graceful error handling is valid and could be a good improvement for the library. If you feel strongly about this, you might want to consider opening an issue on the refine GitHub repository to suggest this improvement. The maintainers are often responsive to user feedback and suggestions for improving the developer experience. For more information on how useGo works and its current implementation, you can refer to the useGo documentation (https://refine.dev/docs/routing/hooks/use-go/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I am using the Link component which uses useGo under the hood

Let me check the knowledge base for you again. One moment! :books: ---------------------- You're correct that the <Link> component in refine uses useGo under the hood. Let's explore this based on the information provided in the knowledge sources. The <Link> component is indeed a wrapper around useGo and provides a convenient way to create navigation links in your refine application. According to the Link documentation (https://refine.dev/docs/routing/components/link/), the <Link> component uses routerProvider.Link internally, which in turn leverages useGo for navigation. Here's an example of how you can use the <Link> component:

import { Link } from "@refinedev/core";

const MyComponent = () => {
  return (
    <Link to="/posts">Posts</Link>
  );
};

import { Link } from "@refinedev/core";

const MyComponent = () => {
  return (
    <Link to="/posts">Posts</Link>
  );
};

You can also use it with more complex navigation options:

<Link
  go={{
    to: {
      resource: "posts",
      action: "list",
    },
  }}
>
  Posts
</Link>

<Link
  go={{
    to: {
      resource: "posts",
      action: "list",
    },
  }}
>
  Posts
</Link>

The <Link> component provides a higher-level abstraction over useGo, which means it should handle some of the error cases more gracefully. However, it's important to note that if you're passing invalid resource or action values, you might still encounter issues similar to those you mentioned with useGo. To avoid potential errors, make sure that: 1. The resource you're linking to is properly defined in your <Refine> component's resources prop. 2. The action you're specifying (e.g., "list", "show", "edit") is valid for that resource. 3. When using actions like "show" or "edit", you provide the necessary id parameter. If you're still encountering issues with the <Link> component, you might want to double-check your resource definitions and ensure that all the necessary routes are properly set up. For more detailed information on using the <Link> component and its props, you can refer to the Link documentation (https://refine.dev/docs/routing/components/link/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
