Revised react-loadable

A drop-in replacement for upstream react-loadable that features:

- No React.StrictMode warnings (i.e. removed usage of legacy context and UNSAFE_componentWillMount)
- Webpack plugin tweaked to work with Webpack 4.41.1+ (also works with v5)
- Types included by default (NB: you should remove @types/react-loadable, if you have installed)

I published this because the legacy context API will be removed in React 19 (see [here][react-legacy-context-warn-1] and [here][react-legacy-context-warn-2]), which is not a good news for projects like [Docusaurus][docusaurus].

This package was published in the hope of resolving this issue like this.

Note

Note that the version starts with 5.6.0 to match [semantic versioning][semver-link].

This package is intended as a _drop-in replacement_ for existing projects using react-loadable.
That is, I do NOT plan to add new features, or address tree-shaking issues.

For new projects I recommend using React.lazy or loadable-components instead.

Requirements

This package uses the new React Context API (and the contextType API), so your version of react needs to be 16.6.0 or later.

The Webpack plugin also requires 4.41.1+ or later (it also works on v5).

To install (if you're on yarn):

``yarn
yarn add react-loadable@npm:@seyoon20087/react-loadable
`

Note: The Babel plugin will not work if you install it via other means like yarn install @seyoon20087/react-loadable itself.

To test it on a current framework (like [Docusaurus][docusaurus]), use the [resolutions][yarn-resolutions] or [overrides][npm-overrides] feature in your package.json.

Example:
`json
{
"resolutions": {
"react-loadable": "npm:@seyoon20087/react-loadable"
}
}
`

API Reference

The API reference is identical, so you should be able to use it without updating your code.

For more information, please refer to the upstream README.

The Manifest type from react-loadable/webpack` is the only exception however I don't expect existing projects to break from working.
