Yes, Vue supports JSX, but requires additional configuration. 1. For Vite projects, install @vitejs/plugin-vue-jsx and add vueJsx() plugin in vite.config.js; 2. For Vue CLI projects, install @vue/babel-preset-jsx and add presets in babel.config.js; 3. Use defineComponent and setup functions to return JSX content, pay attention to using Vue conventions such as class and onClick; 4. In the .vue file, you can call the JSX rendering function through h function or component is binding; 5. When using TypeScript, the file is named .tsx, and configure the jsx of tsconfig.json to preserve And jsxImportSource is vue; it should be noted that template syntax such as v-if and v-for are not suitable for JSX, and JavaScript expressions should be used instead. JSX is not mainstream in Vue and is suitable for complex rendering logic scenarios. Complete support needs to be configured in combination with construction tools.
Vue doesn't support JSX out of the box, but you can use JSX in Vue — especially if you're working with Vue 3 and using the Vite or Vue CLI build setup. Here's how to enable and use JSX in your Vue project.
? Why Use JSX in Vue?
While Vue traditionally uses templates, JSX gives you more programming control over rendering — useful for complex component logic, dynamic children, or if you're coming from a React background.
1. Enable JSX Support
For Vite Projects
Install the JSX plugin for Vue:
npm install @vitejs/plugin-vue-jsx -D
Then, update your vite.config.js :
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import vueJsx from '@vitejs/plugin-vue-jsx'
export default defineConfig({
plugins: [
vue(),
vueJsx()
]
}) Now you can use .jsx or .tsx files, or even write JSX inside .vue files in the setup function.
For Vue CLI Projects
If you're using Vue CLI, install the Babel plugin:
npm install @vue/babel-preset-jsx -D
Then in your babel.config.js :
module.exports = {
presets: ['@vue/babel-preset-jsx']
}2. Write JSX in Components
You can now write components using JSX. Here's an example of a .jsx file:
// MyButton.jsx
import { defineComponent } from 'vue'
export default defineComponent({
props: {
label: String,
onClick: Function
},
setup(props) {
return () => (
<button onClick={props.onClick} class="my-button">
{props.label}
</button>
)
}
})Note: Use
classinstead ofclassName, andonClickinstead ofonclick— it follows Vue's DOM conventions.
3. Using JSX in .vue Files (Optional)
You can mix JSX in the <script setup> section:
<script setup>
import { h } from 'vue'
const renderDynamic = () => {
return h('div', { class: 'dynamic' }, [
h('span', 'Hello JSX inside Vue!')
])
}
</script>
<template>
<div>
<!-- You can't use JSX in <template> -->
<!-- But you can call render functions -->
<component :is="renderDynamic" />
</div>
</template> Alternatively, use JSX only in setup() return if you're not using <template> .
4. JSX with TypeScript (.tsx)
If you're using TypeScript, name your file .tsx and define props with interfaces:
import { defineComponent } from 'vue'
interface Props {
name: string
count?: number
}
export default defineComponent({
props: {
name: { type: String, required: true },
count: { type: Number, default: 0 }
},
setup(props: Props) {
return () => (
<div>
<h1>Hello, {props.name}!</h1>
<p>Count: {props.count}</p>
</div>
)
}
}) Make sure your tsconfig.json allows JSX:
{
"compilerOptions": {
"jsx": "preserve",
"jsxImportSource": "vue"
}
}?? Things to Keep in Mind
Templates are still the standard in Vue — JSX is optional and less common.
No template features in JSX : directives like
v-if,v-fordon't work. Use JavaScript expressions instead:// Instead of v-if {show && <p>Shown</p>} // Instead of v-for {items.map(item => <div key={item.id}>{item.label}</div>)}Event handlers: Use
onClick,onInput, etc. (camelCase), and pass functions directly.Use
onUpdate:xxxforv-model-like behavior.- ? Install
@vitejs/plugin-vue-jsx(for Vite) or Babel preset (for Vue CLI) - ? Use
defineComponentandsetupto return a render function - ? Write JSX with Vue's event and binding conventions
- ? Works with TypeScript via
.tsx
Summary
You can use JSX in Vue with the right setup:
It's not as common as in React, but it's powerful for dynamic or reusable render logic.
Basically, Vue supports JSX — just not in templates. Use it where it adds value.

What is headless UI in Vue?
Jul 08, 2025 am 01:38 AM
HeadlessUIinVue refers to a library of UI components that provide no preset styles and only contains core logic and behavior. Its features include: 1. No style restrictions, developers can customize the design; 2. Focus on barrier-free and interactive logic, such as keyboard navigation, state management, etc.; 3. Support Vue framework integration, exposing the control interface through combinable functions or components. Reasons for use include: maintaining design consistency, built-in accessibility, strong component reusability, and lightweight library size. In practical applications, developers need to write HTML and CSS themselves. For example, when building a drop-down menu, the library handles state and interaction, while developers decide on visual presentation. Mainstream libraries include HeadlessUI and RadixVue for TailwindLabs, suitable for
How to watch nested properties in Vue 3?
Jul 07, 2025 am 12:51 AM
In Vue3, there are three ways to monitor nested properties using the watch function: 1. Use the getter function to accurately monitor specific nested paths, such as watch(()=>someObject.nested.property,callback); 2. Add the {deep:true} option to deeply monitor changes within the entire object, which is suitable for situations where the structure is complex and does not care about which property changes; 3. Return an array in the getter to listen to multiple nested values ??at the same time, which can be used in combination with deep:true; in addition, if ref is used, the nested properties in its .value need to be tracked through getter.
Key differences between Vue 2 and Vue 3?
Jul 09, 2025 am 01:29 AM
Vue3 has improved in many key aspects compared to Vue2. 1.Composition API provides a more flexible logical organization method, allowing centralized management of related logic, while still supporting Vue2's Options API; 2. Better performance and smaller package size, the core library is reduced by about 30%, the rendering speed is faster and supports better tree shake optimization; 3. The responsive system uses ES6Proxy to solve the problem of unable to automatically track attribute addition and deletion in Vue2, making the responsive mechanism more natural and consistent; 4. Built-in better support for TypeScript, support multiple node fragments and custom renderer API, improving flexibility and future adaptability. Overall, Vue3 is a smooth upgrade to Vue2,

Jul 05, 2025 am 12:58 AM
Defining routes in Vue projects requires understanding the structure and configuration. The steps are as follows: 1. Install and introduce vue-router, create a routing instance, and pass in a routes array containing path and component; 2. Use dynamic routing matching such as /user/:id to obtain parameters; 3. Use children attribute to implement nested routes; 4. Name the routes with the name attribute for jumping; 5. Use redirect for path redirect. After mastering these core points, you can configure routing efficiently.

Benefits of using ?
Jul 08, 2025 am 12:20 AM
? in regular expressions are used to convert greedy matches to non-greedy, achieving more accurate matches. 1. It makes the content as little as possible to match as little as possible to avoid mismatch across tags or fields; 2. It is often used in scenarios such as HTML parsing, log analysis, URL extraction, etc. that require precise control of the scope; 3. When using it, it is necessary to note that not all quantifiers are applicable. Some tools need to manually enable non-greedy mode, and complex structures need to be combined with grouping and assertions to ensure accuracy. Mastering this technique can significantly improve text processing efficiency.
