In this chapter, we will see how to use RxJs with ReactJS. We will not get into the installation process for Reactjs here, to know about ReactJS Installation refer this link: /reactjs/reactjs_environment_setup.htm
Example
We will directly work on an example below, where will use Ajax from RxJS to load data.
index.js
import React, { Component } from "react";
import ReactDOM from "react-dom";
import { ajax } from ''rxjs/ajax'';
import { map } from ''rxjs/operators'';
class App extends Component {
constructor() {
super();
this.state = { data: [] };
}
componentDidMount() {
const response = ajax(''https://jsonplaceholder.typicode.com/users'').pipe(map(e => e.response));
response.subscribe(res => {
this.setState({ data: res });
});
}
render() {
return (
<div>
<h3>Using RxJS with ReactJS</h3>
<ul>
{this.state.data.map(el => (
<li>
{el.id}: {el.name}
</li>
))}
</ul>
</div>
);
}
}
ReactDOM.render(<App />, document.getElementById("root"));
index.html
<!DOCTYPE html>
<html>
<head>
<meta charset = "UTF-8" />
<title>ReactJS Demo</title>
<head>
<body>
<div id = "root"></div>
</body>
</html>
We have used ajax from RxJS that will load data from this Url − https://jsonplaceholder.typicode.com/users.
When you compile, the display is as shown below −
