@babel/plugin-transform-react-jsx-development

信息

This plugin is included in @babel/preset-react

This plugin is a developer version of @babel/plugin-transform-react-jsx. It is designed to provide enhanced validation error messages and precise code location information for debugging React apps. Note that this plugin is intended to be used in a development environment, as it generates significantly more outputs than the production build.

If you are using @babel/preset-react, it will be automatically enabled by the development option so you don't have to install it.

Example​

In

input.jsx
const profile = (
  <div>
    <img src="avatar.png" className="profile" />
    <h3>{[user.firstName, user.lastName].join(" ")}</h3>
  </div>
);

Out

output.js
import { jsxDEV as _jsxDEV } from "react/jsx-dev-runtime";

const _jsxFileName = "input.jsx";
const profile = _jsxDEV("div", {
  children: [
    _jsxDEV("img", {
      src: "avatar.png",
      className: "profile",
    }, undefined, false, { fileName: _jsxFileName, lineNumber: 3, columnNumber: 5 }, this),
    _jsxDEV("h3", {
      children: [user.firstName, user.lastName].join(" "),
    }, undefined, false, { fileName: _jsxFileName, lineNumber: 4, columnNumber: 5 }, this),
  ]},
  undefined, false, { fileName: _jsxFileName, lineNumber: 2, columnNumber: 3 }, this
);
