Package Exports
- babel-plugin-transform-react-inline-elements
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (babel-plugin-transform-react-inline-elements) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
babel-plugin-transform-react-inline-elements
Replaces the
React.createElementfunction with one that is more optimized for production:babelHelpers.jsx.
Note
When used alongside transform-runtime, polyfills (by default including Symbol) are specifically scoped to not pollute the global scope. This breaks usage with React, as it won't have access to that polyfill and will cause your application to fail in legacy browsers.
Even if ['transform-runtime', { helpers: true, polyfill: false }] is specified, it might still break, since helpers come precompiled.
In this case, we recommend importing/requiring babel-polyfill in the entry point of your application and using babel-preset-env with the useBuiltIns option to only include the polyfills your targets need. Alternatively, you can also import/require core-js/modules/es6.symbol by itself.
This transform should be enabled only in production (e.g., just before minifying your code) because, although it improves runtime performance, it makes warning messages more cryptic and skips important checks that happen in development mode, including propTypes.
Example
In
<Baz foo="bar" key="1"></Baz>;Out
babelHelpers.jsx(Baz, {
foo: "bar"
}, "1");
/**
* Instead of
*
* React.createElement(Baz, {
* foo: "bar",
* key: "1",
* });
*/Deopt
// The plugin will still use React.createElement when `ref` or `object rest spread` is used
<Foo ref="bar" />
<Foo {...bar} />Installation
