umijs create my-umi-project

This command will initialize a new Umi project in the "my-umi-project" directory.

Running Your Umi Application
You can run your Umi application using the following command:

npm start

This command launches a development server on your local machine. Open your web browser and navigate to http://localhost:3000 to view your application.

Building Your Umi Application
To build your Umi application for production, execute:

npm run build

This will generate a production build of your application in the "build" directory.

Deploying Your Umi Application
After building your Umi application, deploy it to any production environment that supports Node.js.

Code Snippet
Here's a simple Umi application represented in a code snippet:

javascript

import React from 'react';

import { BrowserRouter as Router, Route, Link } from 'react-router-dom';
const Home = () => (
<div>
<h1>Welcome to Umi!</h1>
<Link to="/about">About</Link>
</div>
);
const About = () => (
<div>
<h1>About Umi</h1>
<p>Umi is a React application framework designed to assist developers in building enterprise-class applications.</p>
</div>
);
const App = () => (
<Router>
<div>
<Route path="/" exact component={Home} />
<Route path="/about" component={About} />
</div>
</Router>
);
export default App;

This code showcases a basic Umi application using React components and routing.

In summary
Umi stands out as a robust React application framework, engineered to assist developers in crafting enterprise-grade applications. Its rich feature set simplifies the development and upkeep of extensive applications, encompassing functionalities like routing, code splitting, internationalization, testing, and extensible plugins.
