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:
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.

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:

However, you can create a custom hook that uses

and returns the data you need. Here's an example:
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:
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.

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

@kapa.ai i want to make a get call inside of a function and save that data in local storage
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:
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.

how to use useOne or useSimpleList above
@kapa.ai how to use useOne or useSimpleList above
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
:
(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
:
(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.

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.
