Chantilly

A visual drag-and-drop landing page builder for React. Drop it into your app, wire up save/load, and get a full page editor with HTML export.

Install

npm install @byte3-it/chantilly

React 18+ is required as a peer dependency.

Quick start

import { LandingPageBuilder } from '@byte3-it/chantilly'
import type { Project } from '@byte3-it/chantilly'

export default function App() {
  return (
    <LandingPageBuilder
      onSave={(project) => {
        // persist however you like
        localStorage.setItem('project', JSON.stringify(project))
      }}
    />
  )
}

To restore a saved project on load, pass it via initialProject:

const saved = localStorage.getItem('project')

<LandingPageBuilder
  initialProject={saved ? JSON.parse(saved) : undefined}
  onSave={...}
/>

Props

Prop	Type	Description
initialProject	Project	Project to load on mount
onSave	(project: Project) => void | Promise<void>	Called when the user clicks Save
fileManager	FileManagerConfig	Enables the image library modal
customBlocks	CustomBlockDefinition[]	Extra blocks shown at the top of the sidebar
templates	TemplateDefinition[]	Starting-point projects shown in the Templates modal

Exporting HTML

The builder does not include an export button — call exportToHtml yourself, for example inside onSave:

import { exportToHtml } from '@byte3-it/chantilly'

onSave={(project) => {
  const html = exportToHtml(project)
  // upload, download, or store the HTML string
}}

The output is a self-contained HTML file that loads Tailwind CSS from CDN.

File manager

Provide a FileManagerConfig to enable the image picker inside the Image block editor:

import type { FileManagerConfig } from '@byte3-it/chantilly'

const fileManager: FileManagerConfig = {
  listImages:  async ()       => [...],          // return ImageFile[]
  uploadImage: async (file)   => ({ id, url, name }),
  deleteImage: async (id)     => {},
}

<LandingPageBuilder fileManager={fileManager} />

Custom blocks

Register your own block presets — they appear in a dedicated section at the top of the sidebar:

import type { CustomBlockDefinition } from '@byte3-it/chantilly'
import { Zap } from 'lucide-react'

const customBlocks: CustomBlockDefinition[] = [
  {
    id: 'cta',
    label: 'CTA Button',
    icon: <Zap size={16} />,
    elementType: 'button',        // 'button' | 'link'
    defaults: {
      label: 'Get Started',
      href: '/signup',
      variant: 'primary',
      size: 'lg',
      textAlign: 'text-center',
      // any extra metadata you want stored on the block
      trackingId: 'hero-cta',
    },
  },
]

<LandingPageBuilder customBlocks={customBlocks} />

Templates

Supply starting-point projects that users can pick from the Templates modal:

import type { TemplateDefinition } from '@byte3-it/chantilly'

const templates: TemplateDefinition[] = [
  {
    id: 'saas',
    name: 'SaaS Landing',
    description: 'Hero, features, and CTA.',
    thumbnail: 'https://...', // optional preview image
    project: { ... },         // full Project object
  },
]

<LandingPageBuilder templates={templates} />

Reading store state

useBuilderStore is exported for cases where you need to read or react to builder state outside the component tree:

import { useBuilderStore } from '@byte3-it/chantilly'

function ProjectName() {
  const name = useBuilderStore((s) => s.project.name)
  return <span>{name}</span>
}

Storage helpers

Ready-made helpers that implement the fileManager integration for common backends:
