Visual studio code changes format (React-JSX)

I've the following snippet in my index.js

class App extends Component {
render() {
    return ( <div style = { styles.app } >
        Welcome to React!
        </div>
    )
}

}
The code works, but every time I save (ctrl+s) visual studio format the jsx like that:

class App extends Component {
render() {
    return ( < div style = { styles.app } >
        Welcome to React!
        <
        /div>
    )
}

}

How can I solve this? thanks

In the end what did the trick was changing the file format from JavaScript to JavaScript React on the bottom toolbar. I'm publishing it here for future reference since I didn't find any documentation on this topic.

In addition to the above. If you click 'Configure File Association for .js' you can set all .js files to Javascript React

change vscode preferences settings > user settings below:

"files.associations": {
        "*.js":"javascriptreact"
    }

Alternatively, saving the file with a .jsx extension resolves this in vscode.

I had the same challenge and I am hoping to discover a better way of handling this issue in vscode.

I noticed your suggested work-around has to be done each time you open the react file with an extension of .js

Make sure you dont have multiple javascript formatters enabled in your current workspace. (You have to disable the rest of them for your current workspace).

react-beautify mostly does the magic but fails if you have some other JS formatter/beautifier already installed.

In my case, I had react-beautify and JS-CSS-HTML Formatter extension installed. I had to disable the JS-CSS-HTML Formatter for my current workspace.

Install Prettier (if not installed by default) and try to add this to your user or workplace settings:

"prettier.jsxBracketSameLine": true

Do not put linebreak between return and the returned JSX expression.

Trigger autoformat (Alt+Shift+F) and check if works.

I struggled with this but finally found a solution. This is my settings.json

{
    "terminal.integrated.shell.windows": "C:\\Program Files\\Git\\bin\\bash.exe",
    "workbench.startupEditor": "welcomePage",
    "window.zoomLevel": 1,
    "emmet.includeLanguages": {
        "javascript": "javascriptreact",
        "vue-html": "html"
    },
    "editor.formatOnSave": true,
    "javascript.updateImportsOnFileMove.enabled": "always",
    "editor.wordWrap": "on",
    "editor.tabSize": 2,
    "editor.minimap.enabled": false,
    "workbench.iconTheme": "vscode-icons",
    "eslint.autoFixOnSave": true,
    "eslint.alwaysShowStatus": true,
    "beautify.ignore": [
        "**/*.js",
        "**/*.jsx"
    ],
    "prettier.jsxSingleQuote": true,
    "prettier.singleQuote": true
}

I added

"beautify.ignore": ["**/*.js","**/*.jsx"]

You can install an extension like react-beautify that helps you format your jsx code.

It is found here

This extension wraps prettydiff/esformatter to format your javascript, JSX, typescript, TSX file.

I had similar problem, then I found out it was caused by 'beautify' extension. After I uninstalled the extension, everything is working fine.

You can prevent VSC from incorrectly formatting your JSX by adding an association in your settings.json

Code > Preferences > Settings

In the settings window search for associations, click edit in settings.json and then add:

"files.associations": {
    "*.js": "javascriptreact"
}
