useFetcher

An abortable React Hook for using fetch which supports Error handling, timeouts, deserialisations, time logging and re-fetching based on props.

Warning: Hooks are currently a React RFC and not ready for production. Use at minimum [email protected] to use this package.

Installation

npm install use-fetcher

Example usages

import {useFetcher} from 'use-fetcher';
function GitHubUsers(props) {
  const initialState = {};
  const options = {
    method: "GET", //Defaults to GET
    body: {"say":"hello"}, // Defaults to {}, won't work with GET(will be ignored)
    timeout: 1000, // Defaults to 3000ms
    headers: {}, // Defaults to {}
    returnRawFetchResponse:true, //Defaults to false
    runWhenSpecificPropsChanges: [props.reFetchWhenThisPropChanges],// Defaults to []
  }
  const { data, success, abort, error, timeTaken } = useFetcher(
    "https://api.github.com/users",
    initialState,
    options
  );
  //The data would contain the response returned from the URL in case the fetch Call succeeds.
  return <div className="section" />;
}

You can also:

• Specify a timeout field in options as an integer after which the fetch will be aborted
• Cancel the fetch call anytime by calling the abort() returned from useFetch. If abort is supported by browser, abort() will return true.
• Specify calculateTimeTaken field in options to have a returned timeTaken field returned from useFetch
• Re-fetch based on whether a specific prop has changed or not by specifying prop in runWhenSpecificPropsChanges in options.
• Get the raw object returned from fetch by passing returnRawFetchResponse in options
• Get a blob object if the Response header is neither a application/json or application/text

The body and the headers can be passed to fetch using body and headers in options respectively.

Note

The options doesn't need to be passed necessarily, a merge is performed with what is passed and the default values.
