use-axios-request :bulb:

Data fetching is easy with React Hooks for axios!

Features

Make XMLHttpRequests including all features from axios

Several more nice features:

• Familiar API, axios under the hood
• Request auto-cancellation (concurrent requests or when the component unmounts)
• Cache
• Polling
• Render prop-like API
• Fully typed (TS, Flow is coming)
• Callbacks (onSuccess, onError) to derive state

Installing

Using npm:

$ npm install use-axios-request

Using yarn:

$ yarn add use-axios-request

Example

Performing a GET request

import React from 'react';
import { useAxiosRequest } from 'use-axios-request';

const Avatar = ({ username }) => {
  const { isFetching, error, data } = useAxiosRequest(
    `https://api.github.com/users/${username}`
  );

  if (isFetching) {
    return 'Loading';
  }

  if (error) {
    return error.message || 'Error';
  }

  return <img src={data.avatar_url} alt="avatar" />;
};

Performing a POST request

import React from "react";
import { useAxiosRequest } from "use-axios-request";

const NewIssue = ({ title, body, owner, repo }) => {
  const { isFetching, update } = useAxiosRequest();

  return (
    <button
      disabled={isFetching}
      onClick={() => {
        update({
          url: `https://api.github.com/repos/${owner}/${repo}/issues`,
          method: 'post',
          data: {
            title,
            body
          }
        });
      }}
    >
      Submit New Issue
    </button>
  );
};

API

import { useAxiosRequest } from 'use-axios-request';

// TypeScript annotation for response data
type DataTypeResponse = {
  id: string;
  value: string;
};

const Component = () => {
  const config = 'https://api.github.com/users/octocat';
  // config is just an Axios config that is directly passed to axios() function
  // see https://github.com/axios/axios#request-config
  // if omitted or null is provided no request is sent

  const options = {
    // Milliseconds that determine how often should the data with the same config is polled.
    // No polling occures if 0 is passed. Defaults to 0.
    pollInterval: 0,
    // Inspired by "Apollo GraphQL" client https://www.apollographql.com/
    // 'no-cache' (default value) - it never returns cached data, it'll always make network request.
    // 'cache-first' - it returns cached data OR will make network request.
    // 'cache-and-network' - it returns cached data AND will make network request to refresh data.
    cache: 'no-cache | cache-first | cache-and-network',
    // A Callback that is called after a successful response
    onSuccess: () => setShowModal(false),
    // A Callback that is called after an error response
    onError: () => setShowModal(false),
  };

  const {
    // response.data from latest request
    data,

    // is currently fetching
    isFetching,

    // error from latest request
    error,

    // how many requests have been sent with current config
    // it increments if you call refresh or use polling
    requestId,

    // function that sets a new config and triggers a request
    update,

    // re-fetch with existing config
    refresh,
  } = useAxiosRequest<DataTypeResponse>(config, options);
};

Configuration

config could be the following types:

1. null or undefined
2. string (url)
3. object (axios config)

useAxiosRequest triggers a request for every new non-nullable config. So the code below is buggy.

const MyComponent = props => {
  const { data } = useAxiosRequest({
    url: '/api',
    params: { param1: 'param1' },
  });
  return <div>{data}</div>;
};

It causes an infinite loop because useAxiosRequest gets a new object on every render. You have two options to fix it:

1. move the config outside the component

const CONFIG = {
  url: '/api',
  params: { param1: 'param1' },
};
const MyComponent = props => {
  const { data } = useAxiosRequest(CONFIG);
  return <div>{data}</div>;
};

2. memoize the config if it depends on props

const MyComponent = props => {
  const config = React.useMemo(
    () => ({
      url: '/api',
      params: { param1: props.param1 },
    }),
    [props.param1]
  );
  const { data } = useAxiosRequest(config);
  return <div>{data}</div>;
};

Notes

• It's possible to use both update method and passing a config as a first argument to the hook in a single component. Keep in mind that using update method does not make a component re-render the second time while passing a new config as argument does trigger a second render.
• If you use both methods simultaneously (update and passing a config) you might bump into something like this:

const Component = () => {
  const [config, setConfig] = React.useState(
    'https://api.github.com/users/octocat'
  );
  const { update } = useAxiosRequest(config);

  // If you click on 'Use update button', a new request is sent.
  // Then if you lick on 'Use setConfig', nothing happens
  // because literally nothing has changed - you've updated local state
  // to the same value as it was before. useAxiosRequest hook remembers
  // last passed config as an argument and dispatches a new request only
  // if it actually changes.

  return (
    <div>
      <button
        onChange={() => update('https://api.github.com/users/Turanchoks')}
      >
        Use update
      </button>
      <button
        onChange={() => setConfig('https://api.github.com/users/octocat')}
      >
        Use setConfig
      </button>
    </div>
  );
};

• If you use polling, it's likely that you don't want to show spinner whenever a polling request occurs. You can use requestId property which equals 1 on the very first request. So isFetching && requestId === 1 is true when it's a initial request.
