Hi @Lost Spartan. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- It looks like you're experiencing a CORS (Cross-Origin Resource Sharing) issue with your GraphQL server when using it with refine. This is a common issue when your frontend application is running on a different origin (domain, port, or protocol) than your API server. Based on the knowledge sources, there are a few approaches to solve this issue: 1. Configure CORS on your server Your GraphQL server needs to be configured to allow requests from your refine application's origin. The server should include the appropriate CORS headers in its responses, particularly the Access-Control-Allow-Origin header. 2. Network mode configuration If you're working in a local development environment, you can also try configuring the network mode in your refine application. This is particularly useful when working offline or with local servers:

<Refine
  // ...
  options={{
    // ...
    reactQuery: {
      clientConfig: {
        defaultOptions: {
          queries: {
            networkMode: "offlineFirst" // or "always"
          },
          mutations: {
            networkMode: "offlineFirst" // or "always"
          },
        },
      },
    },
  }}
/>

<Refine
  // ...
  options={{
    // ...
    reactQuery: {
      clientConfig: {
        defaultOptions: {
          queries: {
            networkMode: "offlineFirst" // or "always"
          },
          mutations: {
            networkMode: "offlineFirst" // or "always"
          },
        },
      },
    },
  }}
/>

This configuration helps with handling network requests when there are connectivity issues, as mentioned in this GitHub issue. 3. Custom headers If you're using Strapi or another backend that requires specific headers, make sure you're including all necessary headers in your requests:

headers: ['Content-Type', 'Authorization', 'X-Requested-With', 'Origin', 'Accept']

headers: ['Content-Type', 'Authorization', 'X-Requested-With', 'Origin', 'Accept']

4. Check your GraphQL client configuration Make sure your GraphQL client is properly configured. If you're using a custom GraphQL server, you might need to create a custom data provider that matches your API's schema and endpoints, as mentioned in this GitHub issue. If you continue to face issues, you might need to provide more details about your specific setup, including: - Where your refine app is running (localhost, specific IP, etc.) - Where your GraphQL server is running - Any custom data provider configuration you're using The 405 error specifically indicates "Method Not Allowed," which suggests that your server might not be accepting the HTTP method (likely POST) that refine is using for GraphQL requests. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai also having into consideration the naming conventions for graphql to work out of the box my defined graphql should be allStudents instead of student{}

kapa.ai•2d ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- You're correct about the naming conventions for GraphQL in refine. Based on the knowledge sources, refine's GraphQL data provider has certain expectations about how your GraphQL queries and responses are structured. By default, the GraphQL data provider expects: 1. Resources to be in plural form in the response (e.g., "allStudents" instead of "student") 2. A specific structure for queries and mutations If your GraphQL schema uses different naming conventions, you have a few options: Option 1: Follow refine's default conventions Structure your GraphQL schema to match refine's expectations, using plural resource names like "allStudents". Option 2: Configure the data provider with custom options You can customize how the data provider maps responses by providing options when creating the data provider:

import dataProvider, { GraphQLClient } from "@refinedev/graphql";
import camelCase from "camelcase";

const client = /* client init */

const dataProvider = createDataProvider(client, {
  getList: {
    dataMapper: (response, params) => {
      // resource: students
      const operationName = `all${camelCase(resource, {pascal: true})}`
      // operationName: allStudents
      return response.data?.[operationName].nodes;
    },
  }
})

import dataProvider, { GraphQLClient } from "@refinedev/graphql";
import camelCase from "camelcase";

const client = /* client init */

const dataProvider = createDataProvider(client, {
  getList: {
    dataMapper: (response, params) => {
      // resource: students
      const operationName = `all${camelCase(resource, {pascal: true})}`
      // operationName: allStudents
      return response.data?.[operationName].nodes;
    },
  }
})

This allows you to extract data from responses that don't follow the default naming convention, as shown in the GraphQL documentation. Option 3: For Hasura specifically If you're using Hasura, you can specify the naming convention when creating the data provider:

import dataProvider from "@refinedev/hasura";

const client = /* client init */

const hasuraDataProvider = dataProvider(client, { namingConvention: "graphql-default" });

import dataProvider from "@refinedev/hasura";

const client = /* client init */

const hasuraDataProvider = dataProvider(client, { namingConvention: "graphql-default" });

This is particularly useful if you're using Hasura's "graphql-default" naming convention, which uses PascalCase for types (like "TaskStagesBoolExp") instead of snake_case ("task_stages_bool_exp") as mentioned in several GitHub issues (#6085, #6627). Additionally, if you need to handle deeper nested data in GraphQL responses, you might need to use the gqlDataPath and gqlCountPath properties in your meta options, as discussed in this GitHub issue. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai in my case i decided to define the graphql root schema the following way resource{ getAll(perPage: Intpage: Int): [resourceObject!] } the resourceObject being all the fields that said resource is supposed to have

kapa.ai•2d ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Based on your GraphQL schema structure, you'll need to customize the refine GraphQL data provider to work with your specific schema design. Your approach uses a structure where each resource has a getAll method that returns an array of resource objects. To make this work with refine, you'll need to customize the data provider to properly map your schema structure. Here's how you can do it:

import { createDataProvider } from "@refinedev/graphql";
import { Client } from "@urql/core";

const client = new Client({ 
  url: "YOUR_GRAPHQL_ENDPOINT",
  // other client options
});

const dataProvider = createDataProvider(client, {
  getList: {
    dataMapper: (response, params) => {
      // Extract data from your custom schema structure
      // where data is at resource.getAll
      const resourceName = params.resource;
      return response.data?.[resourceName]?.getAll || [];
    },
    getTotalCount: (response, params) => {
      // If you have a way to get total count, implement it here
      // Otherwise, return the length of the array
      const resourceName = params.resource;
      return response.data?.[resourceName]?.getAll?.length || 0;
    },
    // You may need to customize how variables are built for pagination
    buildPagination: (params) => {
      const { current = 1, pageSize = 10 } = params.pagination ?? {};
      
      return {
        perPage: pageSize,
        page: current,
      };
    }
  }
  // Add other customizations for create, update, etc. as needed
});

import { createDataProvider } from "@refinedev/graphql";
import { Client } from "@urql/core";

const client = new Client({ 
  url: "YOUR_GRAPHQL_ENDPOINT",
  // other client options
});

const dataProvider = createDataProvider(client, {
  getList: {
    dataMapper: (response, params) => {
      // Extract data from your custom schema structure
      // where data is at resource.getAll
      const resourceName = params.resource;
      return response.data?.[resourceName]?.getAll || [];
    },
    getTotalCount: (response, params) => {
      // If you have a way to get total count, implement it here
      // Otherwise, return the length of the array
      const resourceName = params.resource;
      return response.data?.[resourceName]?.getAll?.length || 0;
    },
    // You may need to customize how variables are built for pagination
    buildPagination: (params) => {
      const { current = 1, pageSize = 10 } = params.pagination ?? {};
      
      return {
        perPage: pageSize,
        page: current,
      };
    }
  }
  // Add other customizations for create, update, etc. as needed
});

This customization tells refine how to extract data from your specific schema structure. The dataMapper function maps the response to the format refine expects, and the getTotalCount function extracts the total count for pagination. Note that this approach differs from refine's default convention which expects plural resource names (like "allStudents"). Your schema uses a structure where the resource itself is the root object with methods like getAll. If you encounter any issues with this approach, you might need to further customize the data provider or consider adjusting your GraphQL schema to better align with refine's expectations as described in the GraphQL documentation. You can also use the meta property in your hooks to provide specific GraphQL queries for each operation:

import { gql } from "@urql/core";

const GET_ALL_QUERY = gql`
  query GetAll($perPage: Int, $page: Int) {
    resource {
      getAll(perPage: $perPage, page: $page) {
        id
        title
        // other fields
      }
    }
  }
`;

// In your component
const { data } = useList({
  resource: "resource",
  meta: { gqlQuery: GET_ALL_QUERY }
});

import { gql } from "@urql/core";

const GET_ALL_QUERY = gql`
  query GetAll($perPage: Int, $page: Int) {
    resource {
      getAll(perPage: $perPage, page: $page) {
        id
        title
        // other fields
      }
    }
  }
`;

// In your component
const { data } = useList({
  resource: "resource",
  meta: { gqlQuery: GET_ALL_QUERY }
});

This approach gives you more control over the exact query being executed for each operation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai the resource in this case is students should i make any changes?

kapa.ai•2d ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Based on your schema structure, you'll need to adapt the data provider to work with your specific "students" resource. Here's how you can customize it for your students resource:

import { createDataProvider } from "@refinedev/graphql";
import { Client } from "@urql/core";
import { gql } from "@urql/core";

const client = new Client({ 
  url: "YOUR_GRAPHQL_ENDPOINT",
  // other client options
});

// Define your specific query for students
const GET_ALL_STUDENTS_QUERY = gql`
  query GetAllStudents($perPage: Int, $page: Int) {
    students {
      getAll(perPage: $perPage, page: $page) {
        id
        // other student fields you need
        name
        age
        // etc.
      }
    }
  }
`;

const dataProvider = createDataProvider(client, {
  getList: {
    dataMapper: (response, params) => {
      // For students resource specifically
      if (params.resource === "students") {
        return response.data?.students?.getAll || [];
      }
      // For other resources, use default or custom mapping
      return response.data?.[params.resource]?.getAll || [];
    },
    getTotalCount: (response, params) => {
      if (params.resource === "students") {
        return response.data?.students?.getAll?.length || 0;
      }
      return response.data?.[params.resource]?.getAll?.length || 0;
    }
  }
  // Add other customizations as needed
});

import { createDataProvider } from "@refinedev/graphql";
import { Client } from "@urql/core";
import { gql } from "@urql/core";

const client = new Client({ 
  url: "YOUR_GRAPHQL_ENDPOINT",
  // other client options
});

// Define your specific query for students
const GET_ALL_STUDENTS_QUERY = gql`
  query GetAllStudents($perPage: Int, $page: Int) {
    students {
      getAll(perPage: $perPage, page: $page) {
        id
        // other student fields you need
        name
        age
        // etc.
      }
    }
  }
`;

const dataProvider = createDataProvider(client, {
  getList: {
    dataMapper: (response, params) => {
      // For students resource specifically
      if (params.resource === "students") {
        return response.data?.students?.getAll || [];
      }
      // For other resources, use default or custom mapping
      return response.data?.[params.resource]?.getAll || [];
    },
    getTotalCount: (response, params) => {
      if (params.resource === "students") {
        return response.data?.students?.getAll?.length || 0;
      }
      return response.data?.[params.resource]?.getAll?.length || 0;
    }
  }
  // Add other customizations as needed
});

Then when using this in your components:

// In your component
const { data } = useList({
  resource: "students",
  meta: { 
    gqlQuery: GET_ALL_STUDENTS_QUERY 
  }
});

// In your component
const { data } = useList({
  resource: "students",
  meta: { 
    gqlQuery: GET_ALL_STUDENTS_QUERY 
  }
});

This approach specifically targets your "students" resource with the schema structure you've defined. The key is to properly map the response data from students.getAll to what refine expects. If you have other operations like create, update, or delete, you'll need to customize those as well to match your schema structure. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
