Call a hook inside a function

// Package Imports import { useSimpleList } from '@refinedev/antd'; // Project Imports import resources from 'core/resources/resources'; import { type RolePermission } from 'interfaces/interface'; import type ResourceItem from 'interfaces/resource'; export const useGetData = (value) => { const { listProps } = useSimpleList<RolePermission>({ resource: "products", filters: { permanent: [ { field: 'input_source_connections', operator: 'in', value, }, ], }, }); return listProps } const fetchPermissions = async ( setFilteredResources: React.Dispatch<React.SetStateAction<ResourceItem[]>>, setCrudPermission: React.Dispatch<React.SetStateAction<string[]>>, setModulePermission: React.Dispatch<React.SetStateAction<string[]>>, value: string | undefined ): Promise<void> => { debugger // eslint-disable-line const data = useGetData(value); console.log(data) const modulesWithPermissions: string[] = []; const moduleWithAccess: string[] = ['dashboard']; setModulePermission(moduleWithAccess); setCrudPermission(modulesWithPermissions.flat()); console.log(resources, "resources"); const newResources = resources.filter((resource: any) => moduleWithAccess.includes(resource.identifier) ); setFilteredResources(newResources); }; export default fetchPermissions;

Hi @jash.s. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- In React, hooks cannot be called inside regular JavaScript functions. They can only be called at the top level of a React function component or a custom hook. This is one of the Rules of Hooks (https://reactjs.org/docs/hooks-rules.html) that are enforced by the linter plugin. In your code, you're trying to call the useGetData hook inside the fetchPermissions function, which is not a React component or a custom hook. This is why you're getting an error. To fix this, you could convert fetchPermissions into a custom hook. Here's an example of how you could do this:
import { useState, useEffect } from 'react';
import { useSimpleList } from '@refinedev/antd';
import resources from 'core/resources/resources';
import { type RolePermission } from 'interfaces/interface';
import type ResourceItem from 'interfaces/resource';

export const useGetData = (value) => {
const { listProps } = useSimpleList<RolePermission>({
resource: "products",
filters: {
permanent: [
{
field: 'input_source_connections',
operator: 'in',
value,
},
],
},
});

return listProps;
}

export const useFetchPermissions = (value) => {
const [filteredResources, setFilteredResources] = useState([]);
const [crudPermission, setCrudPermission] = useState([]);
const [modulePermission, setModulePermission] = useState([]);
const data = useGetData(value);

useEffect(() => {
const modulesWithPermissions = [];
const moduleWithAccess = ['dashboard'];

setModulePermission(moduleWithAccess);
setCrudPermission(modulesWithPermissions.flat());

const newResources = resources.filter((resource) =>
moduleWithAccess.includes(resource.identifier)
);
setFilteredResources(newResources);
}, [value, data]); // re-run the effect when `value` or `data` changes
return { filteredResources, crudPermission, modulePermission };
};
import { useState, useEffect } from 'react';
import { useSimpleList } from '@refinedev/antd';
import resources from 'core/resources/resources';
import { type RolePermission } from 'interfaces/interface';
import type ResourceItem from 'interfaces/resource';

export const useGetData = (value) => {
const { listProps } = useSimpleList<RolePermission>({
resource: "products",
filters: {
permanent: [
{
field: 'input_source_connections',
operator: 'in',
value,
},
],
},
});

return listProps;
}

export const useFetchPermissions = (value) => {
const [filteredResources, setFilteredResources] = useState([]);
const [crudPermission, setCrudPermission] = useState([]);
const [modulePermission, setModulePermission] = useState([]);
const data = useGetData(value);

useEffect(() => {
const modulesWithPermissions = [];
const moduleWithAccess = ['dashboard'];

setModulePermission(moduleWithAccess);
setCrudPermission(modulesWithPermissions.flat());

const newResources = resources.filter((resource) =>
moduleWithAccess.includes(resource.identifier)
);
setFilteredResources(newResources);
}, [value, data]); // re-run the effect when `value` or `data` changes
return { filteredResources, crudPermission, modulePermission };
};
In this code, useFetchPermissions is a custom hook that uses other hooks (useState, useEffect, and useGetData). It returns the state variables filteredResources, crudPermission, and modulePermission, which can be used in your component. Remember to call this hook at the top level of your component, not inside a callback or a loop. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

how can i call a simpleList inside a function and set data ? @kapa.ai

Let me check the knowledge base for you. One moment! :books: ---------------------- In React, hooks cannot be called inside regular JavaScript functions. They can only be called at the top level of a React function component or a custom hook. This is one of the Rules of Hooks (https://reactjs.org/docs/hooks-rules.html) that are enforced by the linter plugin. However, you can create a custom hook that uses useSimpleList and returns the data you need. Here's an example:
import { useSimpleList } from "@refinedev/antd";

export const useGetData = (value) => {
const { listProps } = useSimpleList({
resource: "products",
filters: {
permanent: [
{
field: 'input_source_connections',
operator: 'in',
value,
},
],
},
});

return listProps.data;
}
import { useSimpleList } from "@refinedev/antd";

export const useGetData = (value) => {
const { listProps } = useSimpleList({
resource: "products",
filters: {
permanent: [
{
field: 'input_source_connections',
operator: 'in',
value,
},
],
},
});

return listProps.data;
}
In this code, useGetData is a custom hook that uses useSimpleList and returns the data. You can use this hook in your React components like this:
import React, { useEffect, useState } from 'react';
import { useGetData } from './useGetData';

const MyComponent = () => {
const [data, setData] = useState(null);
const fetchedData = useGetData('myValue');

useEffect(() => {
setData(fetchedData);
}, [fetchedData]);

// ...
}
import React, { useEffect, useState } from 'react';
import { useGetData } from './useGetData';

const MyComponent = () => {
const [data, setData] = useState(null);
const fetchedData = useGetData('myValue');

useEffect(() => {
setData(fetchedData);
}, [fetchedData]);

// ...
}
In this code, MyComponent is a React component that uses the useGetData hook to fetch data and store it in its state. The useEffect hook is used to update the state whenever fetchedData changes. Remember to call this hook at the top level of your component, not inside a callback or a loop. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai i want this to be just a function and set data in context not a jsx component
kapa.ai

Let me check the knowledge base for you. One moment! :books: ---------------------- In React, hooks like useSimpleList can only be used inside React components or custom hooks. They cannot be used inside regular JavaScript functions. This is due to the way hooks work - they rely on the React component lifecycle and context, which is not available in regular functions. If you want to fetch data and provide it to your application using context, you can create a context provider component that fetches the data and provides it via context. Here's an example:
import React, { createContext, useState, useEffect } from 'react';
import { useSimpleList } from '@refinedev/antd';

// Create a context
export const DataContext = createContext(null);

export const DataProvider = ({ children }) => {
const [data, setData] = useState(null);
const fetchedData = useSimpleList({
resource: "products",
filters: {
permanent: [
{
field: 'input_source_connections',
operator: 'in',
value: 'myValue',
},
],
},
});

// When fetchedData changes, update the state
useEffect(() => {
setData(fetchedData);
}, [fetchedData]);

// Provide the data to children components
return (
<DataContext.Provider value={data}>
{children}
</DataContext.Provider>
);
};
import React, { createContext, useState, useEffect } from 'react';
import { useSimpleList } from '@refinedev/antd';

// Create a context
export const DataContext = createContext(null);

export const DataProvider = ({ children }) => {
const [data, setData] = useState(null);
const fetchedData = useSimpleList({
resource: "products",
filters: {
permanent: [
{
field: 'input_source_connections',
operator: 'in',
value: 'myValue',
},
],
},
});

// When fetchedData changes, update the state
useEffect(() => {
setData(fetchedData);
}, [fetchedData]);

// Provide the data to children components
return (
<DataContext.Provider value={data}>
{children}
</DataContext.Provider>
);
};
In this code, DataProvider is a React component that fetches data using useSimpleList and provides it via DataContext. You can use this component to wrap any part of your application that needs access to the data. Inside those components, you can use the useContext(DataContext) hook to access the data. Remember, hooks like useSimpleList and useState must be called at the top level of a React component or a custom hook. They cannot be called inside loops, conditions, or nested functions. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai i want to make a get call inside of a function and save that data in local storage
kapa.ai
kapa.ai4mo ago
Let me check the knowledge base for you. One moment! :books: ---------------------- You can use the fetch API to make a GET request inside a function and then save the response data to local storage. Here's an example:
async function fetchDataAndSave() {
const response = await fetch('<https://api.example.com/data'>);
if (!response.ok) {
throw new Error('Network response was not ok');
}
const data = await response.json();

// Save data to local storage
localStorage.setItem('myData', JSON.stringify(data));
}
async function fetchDataAndSave() {
const response = await fetch('<https://api.example.com/data'>);
if (!response.ok) {
throw new Error('Network response was not ok');
}
const data = await response.json();

// Save data to local storage
localStorage.setItem('myData', JSON.stringify(data));
}
In this function, fetch is used to make a GET request to the API. The response is then converted to JSON and saved to local storage using localStorage.setItem. The data is stringified before being stored because local storage can only store strings. Please replace '<https://api.example.com/data'> with your actual API endpoint. Remember to call this function in an appropriate place in your code, such as in a useEffect hook in a React component if you're using React. Also, note that local storage is synchronous and blocking, and it's not recommended for storing large amounts of data as it could negatively impact your application's performance. For large amounts of data, consider using IndexedDB or a server-side database. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

how to use useOne or useSimpleList above @kapa.ai how to use useOne or useSimpleList above
kapa.ai
kapa.ai4mo ago
Let me check the knowledge base for you. One moment! :books: ---------------------- To use useOne or useSimpleList hooks in your React application, you need to call them inside a React component or a custom hook. Here's how you can use them: useOne The useOne hook is used to fetch a single record from the API. It expects a resource and id property, which will be passed to the getOne method from the dataProvider as a parameter. When these properties are changed, the useOne hook will trigger a new request. Here's an example of how to use useOne:
import { useState } from "react";
import { useOne, HttpError } from "@refinedev/core";

interface IProduct {
id: number;
name: string;
material: string;
}

const ProductList: React.FC = () => {
const [id, setId] = useState(1);

const { data, isLoading, isError } = useOne<IProduct, HttpError>({
resource: "products",
id,
});

const product = data?.data;

if (isLoading) {
return <div>Loading...</div>;
}

if (isError) {
return <div>Something went wrong!</div>;
}

return (
<div>
<h3>Product Details</h3>
<p>id: {product?.id}</p>
<p>name: {product?.name}</p>
<p>material: {product?.material}</p>

<br />

<button onClick={() => setId((prev) => prev - 1)} disabled={id === 1}>
{"<"} Prev Product
</button>
<button onClick={() => setId((prev) => prev + 1)}>Next Product {">"}</button>
</div>
);
};
import { useState } from "react";
import { useOne, HttpError } from "@refinedev/core";

interface IProduct {
id: number;
name: string;
material: string;
}

const ProductList: React.FC = () => {
const [id, setId] = useState(1);

const { data, isLoading, isError } = useOne<IProduct, HttpError>({
resource: "products",
id,
});

const product = data?.data;

if (isLoading) {
return <div>Loading...</div>;
}

if (isError) {
return <div>Something went wrong!</div>;
}

return (
<div>
<h3>Product Details</h3>
<p>id: {product?.id}</p>
<p>name: {product?.name}</p>
<p>material: {product?.material}</p>

<br />

<button onClick={() => setId((prev) => prev - 1)} disabled={id === 1}>
{"<"} Prev Product
</button>
<button onClick={() => setId((prev) => prev + 1)}>Next Product {">"}</button>
</div>
);
};
(Source: useOne Documentation (https://refine.dev/docs/data/hooks/use-one)) useSimpleList The useSimpleList hook is used to fetch a list of records from the API and provides properties that are compatible with the Ant Design's <List> component. It supports features such as sorting, filtering, and pagination. Here's an example of how to use useSimpleList:
import { useSimpleList } from "@refinedev/antd";
import { Typography, List } from "antd";

const { Text } = Typography;

interface IProduct {
id: number;
name: string;
description: string;
price: string;
}

const ProductList: React.FC = () => {
const { listProps } = useSimpleList<IProduct>();

return <List {...listProps} renderItem={renderItem} />;
};

const renderItem = (item: IProduct) => {
const { id, name, description, price } = item;

return (
<List.Item actions={[<Text key={id}>{price}</Text>]}>
<List.Item.Meta title={name} description={description} />
</List.Item>
);
};
import { useSimpleList } from "@refinedev/antd";
import { Typography, List } from "antd";

const { Text } = Typography;

interface IProduct {
id: number;
name: string;
description: string;
price: string;
}

const ProductList: React.FC = () => {
const { listProps } = useSimpleList<IProduct>();

return <List {...listProps} renderItem={renderItem} />;
};

const renderItem = (item: IProduct) => {
const { id, name, description, price } = item;

return (
<List.Item actions={[<Text key={id}>{price}</Text>]}>
<List.Item.Meta title={name} description={description} />
</List.Item>
);
};
(Source: useSimpleList Documentation (https://refine.dev/docs/ui-integrations/ant-design/hooks/use-simple-list)) Remember to replace "products" with your actual resource name and IProduct with your actual data type. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

In this code, useFetchData is a custom hook that uses useOne and returns the data, loading state, and error state. You can use this hook in your React components like this:
import React, { useEffect, useState } from 'react';
import { useFetchData } from './useFetchData';

useEffect(() => {
if (!isLoading && !isError) {
localStorage.setItem('myData', JSON.stringify(data));
setStoredData(data);
}
}, [data, isLoading, isError]);

// ...
}
In this code, MyComponent is a React component that uses the useFetchData hook to fetch data and store it in local storage when the data is loaded without errors. The useEffect hook is used to update the local storage and state whenever the data, loading state, or error state changes. Remember to call this hook at the top level of your component, not inside a callback or a loop. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
