relementjs (Reactive Element)

Isomorphic ui rendering & state management on the browser & server. The smallest reactive UI library on the browser & server. relementjs scales large & small with tree-shakable modules for rendering, reactivity, contexts, & hydration.

relementjs started as a fork from VanJS. The bold use cases have rough equivalence to what VanJS provides. The browser export is smaller than VanJS. The server export is smaller than mini-van-plate/van-plate. relementjs exports rmemo for reactivity & ctx-core/be for contexts.

isomorphic rendering

import { relement__use } from 'relementjs'
import { browser__relement } from 'relementjs/browser'
import { a_, div_ } from 'relementjs/html'
relement__use(browser__relement)
div_(
  a_({ href: 'https://github.com/relementjs/relementjs' }, 'relementjs github page'))

browser rendering

import { tags } from 'relementjs/browser'
const { a, div } = tags
div(
  a({ href: 'https://github.com/relementjs/relementjs' }, 'relementjs github page'))

server rendering

import { tags } from 'relementjs/server'
const { a, div } = tags
div(
  a({ href: 'https://github.com/relementjs/relementjs' },
    'relementjs github page'))

rectivity

relementjs uses rmemo for reactivity on the browser & server.
