Appsemble Preact SDK

Build your own blocks using Preact

Installation

npm install @appsemble/preact preact

Hello world example

import { bootstrap } from '@appsemble/preact';
import { h, VNode } from 'preact';

function MyBlock({ actions }): VNode {
  return (
    <button onClick={actions.onClick.dispatch} type="button">
      Hello world!
