Usage

Basic Setup

First, import Formeo into your project:

import { FormeoEditor, FormeoRenderer } from 'formeo'
import 'formeo/dist/formeo.min.css'

Creating a Form Editor

// Create a container element in your HTML
// <div id="formeo-editor"></div>

const editorOptions = {
  editorContainer: '#formeo-editor',
  // Add any additional options here
}

// Initialize the editor
const editor = new FormeoEditor(editorOptions)

Saving Form Data

// Get the form data (typically in an onSave event)
const formData = editor.formData

// Save to your backend
fetch('/api/forms', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify(formData)
})

Rendering a Form

// Create a container element for the rendered form
// <div id="formeo-renderer"></div>

const rendererOptions = {
  editorContainer: '#formeo-renderer',
  // Add any additional options here
}

// Initialize the renderer and render the form
const renderer = new FormeoRenderer(rendererOptions)
renderer.render(formData)

Complete Example

import { FormeoEditor, FormeoRenderer } from 'formeo'
import 'formeo/dist/formeo.min.css'

// Set up the editor
const editor = new FormeoEditor({
  editorContainer: '#formeo-editor',
  events: {
    onSave: (formData) => {
      console.log('Form saved:', formData)
      // Render the form
      renderer.render(formData)
    }
  }
})

// Set up the renderer
const renderer = new FormeoRenderer({
  editorContainer: '#formeo-renderer'
})

}

const editor = new FormeoEditor(options)
