Add coexistence checks to all enqueue methods to prevent loading both React and Grid.js assets simultaneously. Changes: - ReactAdmin.php: Only enqueue React assets when ?react=1 - Init.php: Skip Grid.js when React active on admin pages - Form.php, Coupon.php, Access.php: Restore classic assets when ?react=0 - Customer.php, Product.php, License.php: Add coexistence checks Now the toggle between Classic and React versions works correctly.

# `react-is`
|
|
|
|
This package allows you to test arbitrary values and see if they're a particular React element type.
|
|
|
|
## Installation
|
|
|
|
```sh
|
|
# Yarn
|
|
yarn add react-is
|
|
|
|
# NPM
|
|
npm install react-is
|
|
```
|
|
|
|
## Usage
|
|
|
|
### Determining if a Component is Valid
|
|
|
|
```js
|
|
import React from "react";
|
|
import * as ReactIs from "react-is";
|
|
|
|
class ClassComponent extends React.Component {
|
|
render() {
|
|
return React.createElement("div");
|
|
}
|
|
}
|
|
|
|
const FunctionComponent = () => React.createElement("div");
|
|
|
|
const ForwardRefComponent = React.forwardRef((props, ref) =>
|
|
React.createElement(Component, { forwardedRef: ref, ...props })
|
|
);
|
|
|
|
const Context = React.createContext(false);
|
|
|
|
ReactIs.isValidElementType("div"); // true
|
|
ReactIs.isValidElementType(ClassComponent); // true
|
|
ReactIs.isValidElementType(FunctionComponent); // true
|
|
ReactIs.isValidElementType(ForwardRefComponent); // true
|
|
ReactIs.isValidElementType(Context.Provider); // true
|
|
ReactIs.isValidElementType(Context.Consumer); // true
|
|
ReactIs.isValidElementType(React.createFactory("div")); // true
|
|
```
|
|
|
|
### Determining an Element's Type
|
|
|
|
#### Context
|
|
|
|
```js
|
|
import React from "react";
|
|
import * as ReactIs from 'react-is';
|
|
|
|
const ThemeContext = React.createContext("blue");
|
|
|
|
ReactIs.isContextConsumer(<ThemeContext.Consumer />); // true
|
|
ReactIs.isContextProvider(<ThemeContext.Provider />); // true
|
|
ReactIs.typeOf(<ThemeContext.Provider />) === ReactIs.ContextProvider; // true
|
|
ReactIs.typeOf(<ThemeContext.Consumer />) === ReactIs.ContextConsumer; // true
|
|
```
|
|
|
|
#### Element
|
|
|
|
```js
|
|
import React from "react";
|
|
import * as ReactIs from 'react-is';
|
|
|
|
ReactIs.isElement(<div />); // true
|
|
ReactIs.typeOf(<div />) === ReactIs.Element; // true
|
|
```
|
|
|
|
#### Fragment
|
|
|
|
```js
|
|
import React from "react";
|
|
import * as ReactIs from 'react-is';
|
|
|
|
ReactIs.isFragment(<></>); // true
|
|
ReactIs.typeOf(<></>) === ReactIs.Fragment; // true
|
|
```
|
|
|
|
#### Portal
|
|
|
|
```js
|
|
import React from "react";
|
|
import ReactDOM from "react-dom";
|
|
import * as ReactIs from 'react-is';
|
|
|
|
const div = document.createElement("div");
|
|
const portal = ReactDOM.createPortal(<div />, div);
|
|
|
|
ReactIs.isPortal(portal); // true
|
|
ReactIs.typeOf(portal) === ReactIs.Portal; // true
|
|
```
|
|
|
|
#### StrictMode
|
|
|
|
```js
|
|
import React from "react";
|
|
import * as ReactIs from 'react-is';
|
|
|
|
ReactIs.isStrictMode(<React.StrictMode />); // true
|
|
ReactIs.typeOf(<React.StrictMode />) === ReactIs.StrictMode; // true
|
|
```
