api fetch with react hooks code example

Example 1: await fetch in react

async function fetchFunction() {
  try{
	const response = await fetch(`http://url.com`);
	const json = await response.json();
  }
  catch(err) {
    throw err;
    console.log(err);
  }
}

Example 2: fetch api react

// This is what I've been using, pretty straight forward
// It passes the JSON to the children as props
// Of course, you fetch what you will

import React, { Component, Fragment } from 'react';

export class FetchJsonController extends Component
{
	constructor(props) {
		super(props);
		this.state = {
			data: null,
		};
	}

	componentDidMount() {
		fetch(this.props.src)
			.then(response => response.json())
			.then(data => {
				console.log(data);
				this.setState({ data })
			});
	}

	render() {
		const _data = this.state.data;
		const children = React.Children.map(this.props.children, child => {
			return React.cloneElement(child, {
				jsonData: _data
			});
		});
		return (
			<div>{ children }</div>
		)
	}
}

// This is how it's used
// SomeCompnent will receive the JSON data
<FetchJsonController src="somefile.json">
  <SomeComponent />
</FetchJsonController>
