Why Joyfill’s embeddable form builder?

Forms require a lot more engineering time, resources, and ongoing maintenance than you would first expect. Building a flexible, reliable, and scalable form solution is hard, time-consuming, and comes with a lot of unknown features. Conditional logic, revision management, multi-device compatibility, user collaboration, field validation, export engine, template library, just to name a few.

This is where we come in. With Joyfill you can deploy a form builder in under 15 minutes, and we take care of all of the above and more.

The Prerequisites

Just follow the steps below and you’ll be up and running shortly.

Step 1: Create Joyfill Account

To begin working with Joyfill, go to Joyfill’s Platform and create an account (jump to step 2 if you already have an account). By creating an account you will add yourself as the first user to your newly created Joyfill Organization and be placed inside the Joyfill Manager.

Step 2: Generate Your userAccessToken

Once you’re inside the Joyfill Manager you will want to select from the top navigation bar “Settings & Users” > “Manager Users” > and click the “Access Tokens” button next to your user. Once the modal appears select “Add Access Token”. Copy and securely store your access token for later use.

Step 3: Create Your First Template

Create your first template within the Joyfill Manager by going to the Template Library tab in the top navigation and click the “Add Template”.

We recommend following this guide Create Your First Template when creating your first template. This makes it easy to experiment with the different parts of the Joyfill Platform easily.

Step 4: Get your template identifier

Inside the Joyfill Manager you will want to select from the top navigation bar Template Library and under your Templates table list within the column ID copy that for pasting into our example React/JS guides.

Embed the form builder

By now you should have the following items:

  • Completed the Setup Guide
  • A User Access Token (see setup guide)
  • A Template Identifier (see setup guide)

Lastly, we suggest you Review SDK README.

Step 5: Install the form builder

Using a package manager:

npm install --save @joyfill/components

yarn add @joyfill/components

Using a CDN:


Step 6: Usage

  • Add the Template identifier and User Access Token from the previous setup step to the index.js file.
  • Add the User Access Token from the preview setup step to the api.js file.
  • Important Note: ensure you use the full import path if you’re using JS modules and not the CDN. Full path import Joyfill from '@joyfill/components/dist/joyfill.min.js'


import Joyfill from "@joyfill/components/dist/joyfill.min.js";
import { retrieveTemplate } from './api.js';

const initJoyfill = async () => {

  const identifier = '<REPLACE_YOUR_TEMPLATE_IDENTIFIER>';

  const template = await retrieveTemplate(identifier);

      doc: template,
      mode: 'edit',
      onChange: (changelogs, doc) => {

         * Changelogs represent the individual change that was made
         * Data represents the entire data structure with all new changes applied.
        console.log('onChange: ', changelogs, doc);

const userAccessToken = "<REPLACE_USER_ACCESS_TOKEN>";
const apiBaseUrl = "<>";

export const retrieveTemplate = async (identifier) => {

  //See API Doc Here: <>
  const response = await fetch(`${apiBaseUrl}/v1/templates/${identifier}`, {
    method: 'GET',
    mode: 'cors',
    headers: {
      Authorization: `Bearer ${userAccessToken}`,
      'Content-Type': 'application/json'

  const data = await response.json();
  return data;

And, that’s it! We hope you’ve enjoyed this embed form builder for Javascript guide.
