Package Exports
- use-fetch-with-callbacks
- use-fetch-with-callbacks/dist/index.js
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (use-fetch-with-callbacks) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

🔧 Basic Usage
import useFetchWithCallbacks from 'use-fetch-with-callbacks';
interface User {
id: number;
name: string;
email: string;
}
const UserProfile = () => {
const { response, loading, error, fetchData, postData, deleteData } =
useFetchWithCallbacks<User>('/users/1', {
baseUrl: 'https://api.example.com',
headers: { Authorization: 'Bearer your-token' },

});
const handleFetch = () => {
fetchData({
onSuccess: data => console.log('User loaded:', data),
onError: error => console.error('Failed to load user:', error),
onLoading: loading => console.log('Loading state:', loading),
});
};
const handleUpdate = () => {
postData({
data: { name: 'John Doe', email: 'john@example.com' },
onSuccess: data => console.log('User updated:', data),
onError: error => console.error('Update failed:', error),
});
};
const handleDelete = () => {
deleteData({
onSuccess: data => console.log('User deleted:', data),
onError: error => console.error('Delete failed:', error),
});
};
return (
<div>
<button onClick={handleFetch}>Load User</button>
<button onClick={handleUpdate}>Update User</button>
<button onClick={handleDelete}>Delete User</button>
{loading && <p>Loading...</p>}
{error && <p>Error: {error.message}</p>}
{response && <p>Hello, {response.name}!</p>}
</div>
);
};
� API Reference
RequestParams<T>
The RequestParams<T>
type is used for all request methods (GET, POST, PUT, DELETE, PATCH) and for chainable operations. It allows you to specify the endpoint, request body, and callbacks for handling success, error, and loading states.
type RequestParams<T> = {
endpoint?: string;
data?: unknown;
onSuccess?: (data: T) => void;
onError?: (error: Error) => void;
onLoading?: (loading: boolean) => void;
};
Properties:
endpoint
(string, optional): Override the default endpoint for this request.data
(unknown, optional): Data to send in the request body (for POST, PUT, PATCH).onSuccess
((data: T) => void, optional): Callback executed when the request succeeds.onError
((error: Error) => void, optional): Callback executed when the request fails.onLoading
((loading: boolean) => void, optional): Callback executed when loading state changes.
Example:
fetchData({
endpoint: '/users/1',
onSuccess: user => console.log('Loaded user:', user),
onError: error => console.error('Failed:', error),
onLoading: loading => console.log('Loading:', loading),
});
postData({
endpoint: '/users',
data: { name: 'Jane' },
onSuccess: user => console.log('Created:', user),
});
Note: Each chainable method (fetch
, post
, put
, patch
, delete
) now accepts an optional endpoint
as the first argument, allowing you to chain requests to different endpoints in a single workflow.
📡 Multiple Concurrent Requests
const Dashboard = () => {
const { fetchMultipleData } = useFetchWithCallbacks<any>('/', {
baseUrl: 'https://api.example.com',
});
const loadDashboard = () => {
fetchMultipleData({
endpoints: ['/users', '/posts', '/comments'],
onSuccess: results => {
console.log('All data loaded:', results);
},
onError: error => console.error('Failed to load dashboard:', error),
});
};
return <button onClick={loadDashboard}>Load Dashboard</button>;
};
🎛️ Advanced Configuration
const api = useFetchWithCallbacks<ApiResponse>('/data', {
baseUrl: 'https://api.example.com',
headers: {
Authorization: 'Bearer token',
'Content-Type': 'application/json',
'X-Custom-Header': 'value',
},
timeout: 10000, // 10 second timeout
});
📝 API Reference
useFetchWithCallbacks<T>(endpoint, options?)
Parameters:
endpoint
(string): The API endpoint pathoptions
(UseFetchOptions): Optional configuration
Returns: FetchResult<T>
FetchResult<T>
interface FetchResult<T> {
response: T | null;
loading: boolean;
error: Error | null;
requestCompleted: boolean;
fetchData: (...) => Promise<void>;
postData: (...) => Promise<void>;
putData: (...) => Promise<void>;
deleteData: (...) => Promise<void>;
patchData: (...) => Promise<void>;
fetchMultipleData: (...) => Promise<void>;
chain: () => ChainableRequest<T>;
}
UseFetchOptions
interface UseFetchOptions {
baseUrl?: string; // Base URL for all requests
headers?: HeadersInit; // Default headers
timeout?: number; // Request timeout (default: 10000ms)
}
RequestParams<T>
The RequestParams<T>
type is used for all request methods (GET, POST, PUT, DELETE, PATCH) and for chainable operations. It allows you to specify the endpoint, request body, and callbacks for handling success, error, and loading states.
type RequestParams<T> = {
endpoint?: string; // Optional
data?: unknown; // Optional
onSuccess?: (data: T) => void; // Optional
onError?: (error: Error) => void; // Optional
onLoading?: (loading: boolean) => void; // Optional
};
Properties:
endpoint
(string, optional): Override the default endpoint for this request.data
(unknown, optional): Data to send in the request body (for POST, PUT, PATCH).onSuccess
((data: T) => void, optional): Callback executed when the request succeeds.onError
((error: Error) => void, optional): Callback executed when the request fails.onLoading
((loading: boolean) => void, optional): Callback executed when loading state changes.
Example:
fetchData({
endpoint: '/users/1',
onSuccess: user => console.log('Loaded user:', user),
onError: error => console.error('Failed:', error),
onLoading: loading => console.log('Loading:', loading),
});
postData({
endpoint: '/users',
data: { name: 'Jane' },
onSuccess: user => console.log('Created:', user),
});
ChainableRequest<T>
The chain
API allows you to compose and execute multiple requests in sequence, with full callback support for each step and for the overall chain. Each chainable method can override the endpoint and provide per-request callbacks.
Available methods:
fetch(params?: RequestParams<T>)
post(params: RequestParams<T>)
put(params: RequestParams<T>)
delete(params?: RequestParams<T>)
patch(params: RequestParams<T>)
then(callback: (data: T) => void)
catch(callback: (error: Error) => void)
finally(callback: () => void)
execute()
Example:
const { chain } = useFetchWithCallbacks<User>('/users/1', { baseUrl: 'https://api.example.com' });
chain()
.fetch({
endpoint: '/users/1',
onSuccess: user => console.log('Loaded user:', user),
})
.put({
endpoint: '/users/1',
data: { name: 'Updated Name' },
onSuccess: user => console.log('Updated user:', user),
})
.then(user => {
// Called after the last successful request in the chain
console.log('Chain completed. Final user:', user);
})
.catch(error => {
// Called if any request in the chain fails
console.error('Chain failed:', error);
})
.finally(() => {
// Always called at the end
console.log('Chain finished');
})
.execute();
Tip: Each chainable method (
fetch
,post
,put
,patch
,delete
) accepts an optionalendpoint
and per-request callbacks, allowing you to build flexible, readable workflows.
🛡️ Error Handling
The hook provides comprehensive error handling:
const { fetchData } = useFetchWithCallbacks<User>('/users/1');
fetchData(
data => {
// Success callback
console.log('Success:', data);
},
error => {
// Error callback - handles network errors, timeouts, HTTP errors
if (error.message === 'Request timeout') {
console.log('Request timed out');
} else if (error.message.includes('404')) {
console.log('User not found');
} else {
console.log('Other error:', error.message);
}
}
);
🔄 Request Cancellation
Requests are automatically cancelled when:
- Component unmounts
- New request is initiated
- Timeout is reached
const { fetchData } = useFetchWithCallbacks<User>('/users/1');
// This request will be cancelled if component unmounts
fetchData(
data => console.log('Success:', data),
error => console.log('Error:', error)
);
🎯 TypeScript Support
Full TypeScript support with proper type inference:
interface User {
id: number;
name: string;
email: string;
}
// T is automatically inferred as User
const { response, fetchData } = useFetchWithCallbacks<User>('/users/1');
// response is typed as User | null
// fetchData callbacks receive properly typed data
