Create a Single Page Application with React.js in cherrypy

React contribution to the making of a Single Page Application

SPAs request an indexed HTML file from the server using the forward.com/index URL. To write JavaScript code, React Native uses Node.js, a JavaScript runtime. React is activated when a browser receives this answer. By preventing such a request from getting to the server, it prevents it. Single-page applications become speedier and 100% more dependable in the meantime as it requests and loads the contact component. Upon user request, the React app displays the "components."

React Router

To create single-page applications in React, use the declarative routing features provided by React router. Your comprehension of single-page applications is expanded, and the cross-platform capabilities of React are added.

Navigational components are included in React's robust declarative programming style and are used to declaratively assemble the application. It generates bookmarkable URLs for use in React Native or the web app. Wherever React rendering is available, React Router operates. Web or native options are available.

Building React.js Single-page App

To use React to build a simple single-page application:

Step 1:-  Examine the background settings

• Create your development environment and install the necessary packages and libraries.
• Make an HTML page to start with React.
• Install all the React components you require.
• Fuse the installed "components" using webpack or another bundler to create the web application.

Step 2: To create the Actual App

To create a React App at the chosen location, use "npx create-react-app app-name."

It generates a directory called "app-name" with some default files in it.

Step 3:- Use the commands below to install react-router-dom to route the requests: Install React-Router-DOM with npm

Step 4: To cover the App component, we need a router.

• BrowserRouter – to make URLs like example.com/about
• HashRouter to make URLs like example.com/#/about

Step 5: You should have the following code in your src/index.js file.

import React from "react"
import { render } from "react-dom"
import { BrowserRouter } from "react-router-dom"
import App from "./App"
render(
  <BrowserRouter>
  <App />
  </BrowserRouter>,
  document.querySelector("#root")
)
Step 6: Make a file called src/pages/HomePage.js and add the following code to it:
 import React from "react";
export default function HomePage() {
return (
    <>
      <h1>Hey from HomePage</h1>
      <p>This is my awesome HomePage subtitle</p>
    </>
);
}

Step 7: Make a file called src/pages/UserPage.js containing the code below.

import React from "react";
import { useParams } from "react-router-dom";
export default function UserPage() {
  let { id } = useParams();
  return (
    <>
      <h1>Hello there user {id}</h1>
      <p>This is your beautifulUser Profile page</p>
    </>
  );

Step 8: Switch and Route routers should be used in accordance with your choices. While Route identifies all "routes," Switch aggregates all routes and guarantees that they are prioritized from top to bottom; The chosen "routes" should be included in the App-name.js file; 

import React from "react"
import { Route, Switch } from "react-router-dom"
// to create these two pages in a moment
import HomePage from "./pages/HomePage"
import UserPage from "./pages/UserPage"

export default function App() {
  return (
    <Switch>
      <Route exact path="/" component={HomePage} />
      <Route path="/:id" component={UserPage} />
    </Switch>
  )
}

Step 9: Using Link to link the page within the SPA

Add the following code to HomePage.js in src/pages:

import React from "react"
import { Link } from "react-router-dom"
export default function HomePage() {
  return (
    <div className="container">
      <h1>Home </h1>
      <p>
        <Link to="/your desired link">This is your desired link.</Link>
      </p>
    </div>
  )
}

Step 10: View the localhost development server by running the code.

To create any straightforward software, we have a "primary parent component." The "React Router" assists in choosing which "components" to show and which ones to hide. Each app page becomes a separate component that feeds into the "primary component." The process proceeds: showing the initial frame, creating the content pages; utilizing React Router; fixing the routing, adding some CSS, and highlighting the active link.
