In a real-world development environment, you may want to use Virtual DOM lightly, with only the bare minimum of core functionality.

"Lithent" makes it easy to add, remove, and update virtual DOM to specific parts of a pre-drawn SSR page.

"Lithent" has implemented the bare minimum functionality needed to create and update virtual DOM in general (we only need to know 'render', 'mounter', 'updater', 'renewer', 'mountCallback', and 'updateCallback').

We provide code in the form of 'helpers' that extend the basic functionality, but using the helpers is only optional and users can extend and develop custom helpers for their own projects.

JavaScript users are used to using closures and love to develop with them.

"Lithent" provides a familiar approach to my JavaScript development, as it leverages the properties of higher-order functions and closures to define and recycle the state of a component.

It's easier to use lithent with JSX or HTM.

• Lithent is built on top of JSX.
  • Setting Guide

You don't need to use h functions or JSX, you can call functions to mark them up. When creating a component, use fMount instead of mount. When creating a fragment, use fFragment instead of Fragment.

import { render, h } from 'lithent';
import { fTags, fFragment, fMount } from 'lithent/ftags';

const { section, div, p, br, strong } = fTags;

const fTagComponent = fMount<{ firstProp: number }>((_r, props, children) => {
  return () =>
    fFragment(
      'first inner',
      div({ style: { border: '1px solid red' } }, 'second inner'),
      props.firstProp,
      ...children
    );
});

render(
  fTagComponent(
    { firstProp: 3 },
    div({ style: { border: '1px solid green' } }, `Fchildren1`),
    'Fchildren2',
    br()
  ),
  document.getElementById('root')
);

• Htm Github

import { lTag } from 'lithent/tag';
const destroy = render(lTag`<${Component} />`, document.getElementById('root'), document.getElementById('#insert-before-this-element'));

• More Examples

import { h, render, mount, Fragment } from 'lithent';
import { lTag } from 'lithent/tag';
import { state } from 'lithent/helper';

const Component = mount((renew, _props) => {
  const count = state(0, renew);

  const change = () => {
    count.value += 1;
  };

  // Updater
  return () => lTag`
    <${Fragment}>
      <li>count: ${count.value}</li>
      <button onClick=${change}>increase</button>
    <//>
  `;
});

// appendChild or insertBefore
// The third argument is an optional value for insertBefore.
const destroy = render(lTag`<${Component} />`, document.getElementById('root'), document.getElementById('#insert-before-this-element'));
