Solving JSX Issues in Vue’s Script Tag

If you’ve encountered issues when using JSX in Vue’s script tag, you’re not alone. JSX, a syntax extension for JavaScript, is commonly associated with React, but it can also be used in Vue.js projects. However, using JSX in Vue’s script tag requires some additional configuration. In this blog post, we’ll explore the solutions to this problem and provide code snippets to help you implement them.

Solution 1: Using Babel

The most common solution to enable JSX in Vue’s script tag is by using Babel, a popular JavaScript compiler. Babel allows you to transform JSX syntax into regular JavaScript that Vue can understand. To set up Babel, follow these steps:

1. Install the necessary dependencies:

npm install --save-dev @babel/preset-react

2. Create a .babelrc file in the root directory of your project:

{
  "presets": ["@babel/preset-react"]
}

3. Update your vue.config.js file to include the Babel configuration:

module.exports = {
  // ...
  transpileDependencies: [
    //node_modules/(?!@babel/runtime)/
  ],
  // ...
}

With these changes, Babel will be able to transform JSX syntax in Vue’s script tag.

Solution 2: Using Vue JSX Plugin

If you prefer not to use Babel or want a more lightweight solution, you can use the Vue JSX plugin. This plugin allows you to write JSX directly in Vue components without the need for additional configuration. To use the Vue JSX plugin, follow these steps:

1. Install the necessary dependencies:

npm install --save-dev @vue/babel-plugin-jsx

2. Create a .babelrc file in the root directory of your project:

{
  "plugins": ["@vue/babel-plugin-jsx"]
}

With these changes, the Vue JSX plugin will enable JSX syntax in Vue’s script tag.

Conclusion

Using JSX in Vue’s script tag requires additional configuration, but it can be easily achieved with either Babel or the Vue JSX plugin. Choose the solution that best fits your project’s needs and start writing JSX in your Vue components.
