Multi Data Provider not working for me
Idk what I'm doing wrong but I get an error Error: (0 , _providers_data_providerWEBPACK_IMPORTED_MODULE_4.dataProvider) is not a function
I'm using Nextjs, AntDesign
in my Layout.tsx
import { dataProvider } from "@providers/data-provider";
dataProvider={{
default: dataProvider(OTHER_API_URL),
fake: dataProvider(API_URL),
}}
in my data-provider.ts
"use client";
import { DataProvider } from "@refinedev/core";
export const dataProvider = (url: string): DataProvider => ({
getList: async ({resource}) => {
const response = await fetch(
${url}/${resource});
const data = await response.json();
return {
data: data.data,
total: data.data.length,
};
},
getOne: async () => {
throw new Error("Not implemented");
},
getMany: async () => {
throw new Error("Not implemented");
},
update: async () => {
throw new Error("Not implemented");
},
updateMany: async () => {
throw new Error("Not implemented");
},
create: async () => {
throw new Error("Not implemented");
},
deleteOne: async () => {
throw new Error("Not implemented");
},
getApiUrl: () => {
return url;
}
})
and in my page where i'm called this
const { data: fabricData, isLoading: fabricIsLoading } = useList({
dataProviderName: "default",
resource:
"crm/fetch/data,
});13 Replies
Hi @jay69. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
The error message you're seeing suggests that
dataProvider is not being recognized as a function. This could be due to a few reasons:
1. Import/Export Issue: Ensure that you're exporting and importing the dataProvider correctly. In your data-provider.ts file, you're using a named export for dataProvider. So, when you're importing it in your Layout.tsx, make sure you're using the correct import statement.
2. Multiple Data Providers: When using multiple data providers, you need to pass an object to the dataProvider prop of the <Refine /> component. Each key-value pair in the object represents a different data provider. The key is the name of the data provider and the value is the data provider itself. The default key is required to define the default data provider. Here's an example:
3. Next.js Server and Client Side: If you're using Next.js, you might encounter issues when trying to use your providers on both the server and client side. Refine heavily uses React context and React state, so it needs to be a client component. You can't pass functions into the Refine component unless you mark them as client functions with "use client"; directive. After marking them as client functions, you can't use them on the server side. To solve this problem, you can create a separate file for your providers and mark them as client or server functions. Then, you can use the appropriate provider in your server and client components. source (https://refine.dev/docs/routing/integrations/next-js#how-can-i-use-my-providers-in-the-both-server-and-client-side)
4. Data Provider Implementation: Ensure that your dataProvider function is implemented correctly. It should return an object with methods for each data operation (getOne, getList, create, update, deleteOne, etc.). Each method should return a Promise that resolves with the data. source (https://refine.dev/docs/data/data-provider)
If you're still having trouble, please provide more details about the error and your implementation.

@kapa.ai do you need any addtional info?
Let me check the knowledge base for you. One moment! :books:
----------------------
To provide a more accurate solution, it would be helpful to have the following additional information:
1. Error Details: More details about the error message you're seeing. Is there any additional information in the error message? Does it include a stack trace? If so, what does the stack trace point to?
2. Refine Version: The version of Refine you're using. There might be version-specific issues or breaking changes that could be causing the problem.
3. Complete Code: The complete code of your
Layout.tsx and data-provider.ts files, and any other relevant files. This can help identify if there are any issues with the way you're using Refine or its data provider.
4. Environment Details: Information about your development environment. For example, the versions of React, Next.js, and Node.js you're using.
5. Steps to Reproduce: The steps you're following that lead to the error. This can help identify if there's a specific action or sequence of actions that triggers the error.
Please provide these details if possible.
