V.I.T.U: Vue Is That You?

This Babel plugin introduces the r-if directive for conditional rendering in React components, inspired by Vue's syntax. With r-if, you can achieve a more streamlined and expressive syntax for conditional rendering in JSX, making it feel a bit like Vue in React.

Installation

To install the plugin, use npm or yarn:

npm install @mg/babel-plugin-v.i.t.u
# or
yarn add @mg/babel-plugin-v.i.t.u

Setup

After installing, configure Babel to use this plugin. Add it to your Babel configuration file (e.g., .babelrc, babel.config.js):

{
  "plugins": ["babel-plugin-v.i.t.u"]
}

Example

Once configured, you can use the r-if attribute in JSX. The component with r-if will only render if the condition inside r-if evaluates to true.

Before compiler

import React, { useState } from 'react';

const App = () => {
	const [isLoggedIn, setIsLoggedIn] = useState(false);

	const toggleLogin = () => {
		setIsLoggedIn((prev) => !prev);
	};

	return (
		<div>
			<h1>Welcome!</h1>
			<div r-if={isLoggedIn}>You are logged in.</div>
			<div r-if={!isLoggedIn}>Please log in.</div>
			<button onClick={toggleLogin}>{isLoggedIn ? 'Log Out' : 'Log In'}</button>
		</div>
	);
};

export default App;

After compile

import React, { useState } from 'react';

const App = () => {
	const [isLoggedIn, setIsLoggedIn] = useState(false);
	const toggleLogin = () => {
		setIsLoggedIn((prev) => !prev);

	return (
		<div>
			<h1>Chào mừng!</h1>

			{!isLoggedIn && <div>False</div>}
			<button onClick={toggleLogin}>
