@ryantate/react-html

react-html

Write react apps without JSX. Library exposes a function for each intrinsic HTML element and is more terse than JSX with corresponding closing tags.

Written in TypeScript with the appropriate type definitions for each element's attributes. Extensively tested with all valid element/attribute combinations per WHATWG. Applications and components built on these functions do not require the .tsx file extension or that a jsx setting be defined in tsconfig.json. Other JSX restrictions do not apply as well, for instance component names are free to start with a lower case letter.

Installation

npm i @ryantate/react-html

Usage

Syntax

element({attributes} | null, ...children)

import ReactDOM from 'react-dom';
import {div} from '@ryantate/react-html';

ReactDOM.render(
    document.getElementById('#root'),
    div({id: 'app'}) // OK
);

ReactDOM.render(
    document.getElementById('#root'),
    div({foo: 'bar'}) // Compile time error
);

// error TS2345: Argument of type '{ foo: string; }' is not assignable to parameter of type 'DetailedHTMLProps<HTMLAttributes<HTMLDivElement>, HTMLDivElement>'. 

Fragments

Fragments have a different signature in that they do not accept attributes. The function exposed from the library to render fragments is _. Keyed fragments are currently unsupported.

import ReactDOM from 'react-dom';
import {_, div, a, h1} from '@ryantate/react-html';

ReactDOM.render(
    document.getElementById('#root'),
    _(
        div({className: 'example'}, 'hello world'),
        a({href: 'https://github.com/ryantate13/react-html'}, 'react-html'),
        h1(null, 'hello world'),
    )
);

SVG Support

SVG support is currently a work in progress. There is adequate information in the sources this project is generated from to expose all SVG elements as functions, but there are cases where names conflict. An <a> tag is valid inside an <svg> element but takes props of a different type than those of an html anchor. Eventually the goal is to make all svg elements available for import from @ryantate/react-html/svg.

import {a} from '@ryantate/react-html';
import {a as svga} from '@ryantate/react-html/svg';
