Schema

The primary resource needed is a defined schema in JSON or a JavaScript object literal. It's recommended that schema attributes mainly define React component props. *** This will check device OS and render native components for Mobile devices (Android, iOS and Windows 10) and Browser based components for browser

*** Simply import

import Form from "react-json-schema-form/Form";
import Form from "react-json-schema-form/index.css";

Example JS schema (ES6)

{
  component: "h2",
  props: {
    className: "w3-form"
  },
  text: "Schema Driven Registration Form!",
  children: [
    {
      component: "BaseInput",
      props: {
        labelText: "User Name",
        placeholder: "Phone number or Email address",
        labelClass: "w3-label",
        type: "text",
        required: "true",
        id: "userName",
        validateOn: "onChange",
        validateRules: [
          {
            rule: "required",
            message: "Phone number or Email address is required"
          }
        ]
      }
    },
    {
      component: "BaseInput",
      props: {
