import {make_form_view} from 'simple-server-side-rosmaro-forms'
let view
view = make_form_view()

view = make_form_view({
  csrf_field_name: "token"
})
 
const make_enter_name_leaf = view(() => ({
 
  render() {

import {render_model} from 'simple-server-side-rosmaro-forms'

app.post('/', async (req, res) => {
  await rosmaro_form_model.handle(req)
  res.redirect('/')
})
 
app.get('/', async (req, res) => {
  //you probably want to add the whole html skeleton as well
  res.send(await render_model(rosmaro_form_model, req.csrfToken()))
})
