Unification layer between React, Preact and Vue3. Write React-like unified components and use everywhere without recompilation.
React as well as Vue3 comes with Virtual DOM and JSX approaches.
There are a few differences at the low level.
This nano-library negates the differences between them on JSX level.
Making it possible to implement universal components that work without recompiling in both React and Vue3.
Also the following React-like core hooks are available for Vue3:
useStateuseEffectuseLayoutEffectuseCallbackuseMemouseRef
Install
$ npm i --save @redneckz/uni-jsxor:
$ yarn add @redneckz/uni-jsxHow to declare universal components
React 17 introduced new JSX transform with separate runtime react/jsx-runtime which can be replaced with the custom one.
For details please check this out https://reactjs.org/blog/2020/09/22/introducing-the-new-jsx-transform.html
To transpile universal components configure TypeScript as follows:
{
"compilerOptions": {
"jsx": "react-jsx",
"jsxImportSource": "@redneckz/uni-jsx"
// ...
}
// ...
}Universal component:
import { JSX } from '@redneckz/uni-jsx';
import { useState, useCallback, useRef, useEffect } from '@redneckz/uni-jsx/lib/hooks';
export interface TextBlockProps {
html?: string;
onClick?: (event: Event) => void;
}
export const TextBlock = JSX<TextBlockProps>(props => {
const { html, onClick, children } = props;
const [isDark, setDark] = useState(false);
const handleClick = useCallback(
(event: Event) => {
setDark(_ => !_);
onClick && onClick(event);
},
[onClick]
);
const ref = useRef<HTMLParagraphElement | null>(null);
useEffect(() => {
console.log('ref', ref.current);
}, []);
const style = isDark ? { color: '#CCC', backgroundColor: '#777' } : {};
return (
<section className="text-block" style={style} onClick={handleClick}>
{html && <p ref={ref} dangerouslySetInnerHTML={{ __html: html }}></p>}
{children && <p>{children}</p>}
</section>
);

Structural Hooks
-
useBool- boolean state with operations
const [isEnabled, { setTrue: enable, setFalse: disable, toggle }] = useBool();-
useList- list with operations
const [items, { push: addItem, pop: removeLastItem, remove: removeItem, clear: removeAllItems }] = useList<BuzItem>();-
useDict- dictionary with operations
const [
form,
{
setDict: updateForm,
setItem: updateField,
removeItem: removeField,
assign: updateFields,
unassign: removeFields,
clear: resetForm
}
] = useDict<BuzForm>({});API-centric Hooks:
-
useAsyncData-useSWR-like hook
const fetcher = useCallback(
async (url: string) => {
await delay(timeout);
return fetchJSON<ChuckJoke>(url);
},
[timeout]
);
const { data: chuckJoke } = useAsyncData<ChuckJoke>(
`https://api.chucknorris.io/jokes/random?category=${CATEGORIES[rnd % CATEGORIES.length]}`,
fetcher
);-
useEventListener- apply event handler to native DOM node
useEventListener(globalThis.document, 'click', handleDocumentClick);-
useOutsideClick- registers callback to handle click outside of some node (menu, dropdown, dialog and so on)
const menuRef = useOutsideClick<HTMLDivElement>(closeDropdownMenu);
...
<div role="menu" ref={menuRef}>...</div>-
useDebouncedEffect- debounced effect with default timeout - 300ms
useDebouncedEffect(
() => {
doSomethingWith(some, dependencies);
},
[some, dependencies],
300
);-
useScript- TODO
// TODOLimitations
Common limitations:
- Events are streamed up as-is (avoid usage of normalized Event fields specific to
ReactorVue)
React specific limitations:
- NO refs forwarding
