The most basic operation you can perform with the framework is to show a variable in the page.
import {rjsf} from '../rjsf.js'
(function()
{
const appElement = document.getElementById('app');
const app = new rjsf(appElement);
const viewmodel =
{
data:
{
message: 'hello world',
}
};
app.init(viewmodel);
})();
