Syntaxerror: Support For The Experimental Syntax ‘jsx’ Isn’t Currently Enabled: What You Should Do

If you are using a React project and you get an error like “SyntaxError: Support for the experimental syntax ‘jsx’ isn’t currently enabled” don’t worry! You just need to enable support for it. This article explains how to do that. Read on to learn more!

How Did The SyntaxError: Support for the experimental syntax ‘jsx’ isn’t currently enabled Error Occur?

If you are a developer, you sometimes have to encounter the error message “SyntaxError: Support for the experimental syntax ‘jsx’ isn’t currently enabled”. This is because the JavaScript language has been updated with a new syntax called JSX. 

JSX is an extension to JavaScript that helps you write HTML tags within your JavaScript code. 

However, since JSX isn’t supported in all browsers, you may be using an older browser that doesn’t support this new syntax. Or the browser might have a bug where it can’t handle the syntax correctly. 

Although it’s an experimental feature, for now, you can enable support for JSX in your web browser by following the instructions in the following sections. 

3 Effective Solutions For This Error

Here are three methods that you can apply to solve the issue above. Let’s scroll down to learn more!

Solution 1

For years, the Babel compiler has been a mainstay in the React community, helping developers compile their JSX code into regular JavaScript. 

However, due to a recent adjustment in the Babel compiler, React developers are now receiving an error mentioned above when they try to compile their code.

Fortunately, there is a solution! By creating a .babelrc file in your project directory, you can instruct Babel to ignore the error and allow you to use JSX syntax in your code. Then you can add the following line to your .babelrc file:


  “presets”: [“@babel/preset-env”, “@babel/preset-react”]


This tells Babel to ignore any JSX syntax errors and allows you to continue using JSX syntax in your code. 

Solution 2

In order to use React with Babel, you need to create a babel.config.js file. This file will tell Babel which features of React to support. You’ll also need to enable the “jsx” experimental syntax in this file. To do this, you need to add these lines to your file: 

module.exports = {






Solution 3

The first step is to open node_modules/react–scripts/config/webpack.config.js and set it up as below:  

babelrc: true

Now, your problem is fixed successfully. 


In conclusion, to solve the SyntaxError: Support for the experimental syntax ‘jsx’ isn’t currently enabled error, you’ll need to enable support for the experimental syntax. 

You can do this in the settings of your development environment. Once support is enabled, you will use it correctly in your code.
