React-use-data-hook

Reusable hook for data retrieval. Can Fetch on mount (optionally) and refetch.

Just inject a function that returns a Promise with your data.

Installation

npm i react-use-data-hook

yarn add react-use-data-hook

Features

• Stale requests are canceled.
• Initial fetch or only on demand, using refetch method.
• Loading, error and data variables
• Error field
• Strongly typed in TS
• Unit tested

Quick start

const getDataById = (id) => Promise.resolve('Some data')

import useDataHook from 'react-use-data-hook'

function MyComponent({id}){

    const { data, loading, error, refetch } = useDataHook(getDataById, id);

    return (
        <>
            {loading && <span>Loading</span>}
            {!loading && <>
                <span>{data}</span>
                <button onClick={()=>refetch(id)}>Click</button>
            </>
            }
            {error && <span>{error}</span>}

        </>
    )
}

Parameters

    const options = { 
        fn: () => Promise.resolve({})), 
        initialFetch: false, 
        debug: false,
        default: []
    }
    const { data, loading, error, refetch } = useDataHook(options, asyncParameters);

The useDataHook has to be called with one or more parameters.

Options can either be an options object or an async function to be called. The asyncParameters can be one or more arguments that will be used to call the async function.

    // example 1: using a function and multiple arguments
    const { data, loading, error, refetch } = useDataHook(getUsersById, userOneId, userTwoId);

    // example 2: using an options object and no arguments
    
    const options = { fn: getAllUsers, initialFetch: false, debug: true }
    const { data, loading, error, refetch } = useDataHook(options);

Options object

Property name	Default	Required	Description
fn	undefined	true	Async function that returns a Promise
initialFetch	false	false	Should a request be made on mount
debug	false	false	Console log debug information
default	null	false	optional default value

Look at the example in the ./example folder for a type-ahead input field using this hook.
