Component with Data
class App extends React.Component {
constructor(props) {
super(props);
this.state = {
items: [],
isLoaded: false,
};
}
componentDidMount() {
fetch('https://jsonplaceholder.typicode.com/posts')
.then(res => res.json())
.then(result => {
this.setState({
isLoaded: true,
items: result
});
});
}
render() {
const { items } = this.state;
if (!isLoaded) {
return <div>Loading ... </div>;
} else {
return (
<ul>
{items.map(item => (
<li key={item.id}>
<h3>{item.title}</h3>
<p>{item.body}</p>
</li>
))}
</ul>
);

Fetching Data - HaReact get method
/* React get method. */
componentWillMount(){
fetch('/getcurrencylist',
{
/*
headers: {
'Content-Type': 'application/json',

},
*/
method: "get",
dataType: 'json',
})
.then((res) => res.json())
.then((data) => {
var currencyList = [];
for(var i=0; i< data.length; i++){
var currency = data[i];
currencyList.push(currency);
}
console.log(currencyList);
this.setState({currencyList})
console.log(this.state.currencyList);
})
.catch(err => console.log(err))
}using componentdidmount with fetch
import React, { Component } from 'react';
class App extends Component {
