Research direction

Review the Angular, React, and Vue tutorial pages linked in the issue, then locate the existing event-binding examples in each sample app. Done means all three apps demonstrate editable text fields and a checkbox, plus a button that swaps the text values and toggles the checkbox through model-to-view updates.

Written by the indexing model from the issue text.

Description

Thank you for all three sample apps (angular, react, vue), really helpful in evaluations and discussions,

Would it be possible to extend all three apps, with the two-way binding, even the simplest way?

Like for example: two text fields and one checkbox, which can be edited in UI, for view to model changes.
And one button, with the click logic to swap the text fields’ bound data values and toggle the checkbox bound data value, for model to view changes?

The reason I am asking is that two-way binding looks like a kind of challenge.

Angular tutorial

You can use two-way data binding with the following components: CheckBox, RadioButton, Input, DatePicker, Switch, TextArea. In order to use it, you have to use a library called Origami ...

React tutorial

Data binding not mentioned at all, only event binding. There are more possibilities in React, one could be shown as example.

Vue tutorial

v-model binding doesn’t work as expected for custom elements. In order to use two way data binding, you should bind and update the value yourself like this

<ui5-input
    :value="inputValue"
    @input="inputValue = $event.target.value">
</ui5-input>
