• Installation
• Setting Up
• Additional Features

Installation

NPM:

npm install fetch-hoc-redux --save

Yarn:

yarn add fetch-hoc-redux

Setting Up

Setup Reducer

Import fetchHOCReducer to your Redux setup:

import {createStore} from "redux";
import {fetchRootReducer, fetchHOCReducer} from "fetch-hoc-redux";

// specify as root reducer
let rootReducer = createStore(fetchRootReducer);

// or specify in combineReducers
let rootReducer = combineReducers({
  __FETCHER__: fetchHOCReducer,
  });

Setup Component

Wrap your component:

import fetchHOC from "fetch-hoc-redux";
import YourReactComponent from "./myComponent";

let URL = 'https://newsapi.org/v1/articles';

let WrapperComponent = fetchHOC(URL)(YourReactComponent);

Additional Features

Variable To Endpoint Mapping

You can also specify one to one variable mapping to set variable on the URL. It will receives state from your redux state or from parent props.

import fetchHOC from "fetch-hoc-redux";
import YourReactComponent from "./myComponent";
import {API_KEY} from "./APIKey";

let URL =
  "https://newsapi.org/v1/articles?source=bar&apiKey=foo";

let mapFromState = (state) => {
  return {
    foo: API_KEY,
  };
};

let mapFromProps = (props) => {
  return {
    bar: props.source,
  }
}

let WrapperComponent = fetchHOC(URL, mapFromState, mapFromProps)(YourReactComponent);

Multiple Endpoints

For multiple endpoints, currently you can combine multiple fetch HOC Component:

import YourReactComponent from "./myComponent";
import {URL_1, URL_2} from "./URLs";

let WrapperComponent = fetchHOC(URL_1)(YourReactComponent);

export default fetchHOC(URL_2)(WrapperComponent)

Resulting data will be an array of data.

Passed Props

Prop	Type	Description
data	Array or Object or undefined	Fetched data results, will be in array form if multiple endpoints are used
isLoading	boolean
isSuccess	boolean
refetch	Function	trigger refetch

Wrapping multiple Fetch HOC will make isLoading, isSuccess, and refetch prop of latter component overwrites former Fetch HOC.
