A complete react form builder that interfaces with a json endpoint to load and save generated forms.

  • Save form data with dummy api server
  • Show posted data on readonly form

DEMO Slow Loading.... back-end is running at FREE Heroku.

Editing Items

Basic Usage

var React = require('react');
var FormBuilder = require('react-form-builder2');

  <FormBuilder.ReactFormBuilder />,


var items = [{
  key: 'Header',
  name: 'Header Text',
  icon: 'fa fa-header',
  static: true,
  content: 'Placeholder Text...'
  key: 'Paragraph',
  name: 'Paragraph',
  static: true,
  icon: 'fa fa-paragraph',
  content: 'Placeholder Text...'

  saveUrl='path/to/POST/built/form.json' />

React Form Generator

Now that a form is built and saved, let's generate it from the saved json.

var React = require('react');
var FormBuilder = require('react-form-builder2');

    task_id={12} // Used to submit a hidden variable with the id to the form from the database.
    answer_data={JSON_ANSWERS} // Answer data, only used if loading a pre-existing form with values.
    authenticity_token={AUTH_TOKEN} // If using Rails and need an auth token to submit form.
    data={JSON_QUESTION_DATA} // Question data

display_short boolean Optional Display an optional "shorter page/form" which is common for legal documents or situations where the user will just have to sign or fill out a shorter form with only the critical elements.
read_only boolean Optional Shows a read only version which has fields disabled and removes "required" labels.
variables object Optional Key/value object that can be used for Signature variable replacement.

Read only Signatures

Read only signatures allow you to use a saved/canned signature to be placed into the form. The signature will be passed in through the variables property to ReactFormGenerator and ReactFormBuilder.

To use a read only signature, choose the "Read only" option and enter the key value of the variable that will be used to pass in the signature.

The signature data should be in base 64 format.

There is a variables.js file that contains a sample base 64 signature. This variable is passed into the demo builder and generator for testing. Use the variable key "JOHN" to test the variable replacement.

Vendor Dependencies

In order to make the form builder look pretty, there are a few dependencies other than React. See the example code in index.html for more details.

  • Bootstrap
  • FontAwesome


All relevant styles are located in css/application.css.scss.


$ npm install
$ npm run build:dist
$ npm run serve:api
$ npm start

Then navigate to http://localhost:8080/ in your browser and you should be able to see the form builder in action.
