Enum tsconfig::Jsx

pub enum Jsx {
    React,
    ReactJsx,
    ReactJsxdev,
    ReactNative,
    Preserve,
}

Controls how JSX constructs are emitted in JavaScript files. This only affects output of JS files that started in .tsx files.

For example, this sample code:

export const helloWorld = () => <h1>Hello world</h1>;

Default: “react”

export const helloWorld = () => React.createElement("h1", null, "Hello world");

Preserve: “preserve”

export const helloWorld = () => <h1>Hello world</h1>;

React Native: “react-native”

export const helloWorld = () => <h1>Hello world</h1>;

React 17 transform: “react-jsx”

import { jsx as _jsx } from "react/jsx-runtime";
export const helloWorld = () => _jsx("h1", { children: "Hello world" }, void 0);

React 17 dev transform: “react-jsxdev”

import { jsxDEV as _jsxDEV } from "react/jsx-dev-runtime";
const _jsxFileName = "/home/runner/work/TypeScript-Website/TypeScript-Website/packages/typescriptlang-org/index.tsx";
export const helloWorld = () => _jsxDEV("h1", { children: "Hello world" }, void 0, false, { fileName: _jsxFileName, lineNumber: 7, columnNumber: 32 }, this);

Variants

React

Emit .js files with JSX changed to the equivalent React.createElement calls

ReactJsx

Emit .js files with the JSX changed to _jsx calls

ReactJsxdev

Emit .js files with the JSX to _jsx calls

ReactNative

Emit .js files with the JSX unchanged

Preserve

Emit .jsx files with the JSX unchanged

Trait Implementations

impl Clone for Jsx

fn clone(&self) -> Jsx

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Jsx

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Jsx

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Jsx

fn eq(&self, other: &Jsx) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
