The .tsx file extension is used for TypeScript files that contain JSX syntax. JSX is an extension to JavaScript that allows you to write HTML-like code within JavaScript. On the other hand, .jsx is used for pure JavaScript files that also contain JSX syntax.
When converting a .tsx file to a .jsx file, the main change involves replacing TypeScript-specific syntax with regular JavaScript equivalents. This includes removing type annotations, using regular JavaScript function and object syntax, and ensuring that all JSX components are properly transpiled to JavaScript.
Here’s an example of a basic component written in TypeScript with JSX (filename: MyComponent.tsx):
import React from 'react';
type MyComponentProps = {
name: string;
};
const MyComponent: React.FC = ({ name }) => {
return Hello, {name}!;
};
export default MyComponent;
To convert this .tsx file to a .jsx file, follow these steps:
- Remove the type annotation for the props:
type MyComponentProps = { name: string };
becomesconst MyComponent = ({ name }) => { ... };
- Replace the
React.FC
type withfunction
:const MyComponent: React.FC<MyComponentProps>
becomesconst MyComponent = function ({ name }) { ... };
- Ensure that you have the necessary imports at the top of the file:
import React from 'react';
- Make sure that the JSX syntax in the return statement is properly transpiled to JavaScript. For example,
<div>Hello, {name}!</div>
needs to be transpiled toReact.createElement('div', null, 'Hello, ', name, '!')
.
Here’s the converted .jsx file (filename: MyComponent.jsx) for the given example:
import React from 'react';
const MyComponent = function ({ name }) {
return React.createElement('div', null, 'Hello, ', name, '!');
};
export default MyComponent;
