NPS

Net Promoter Score widget for Vaadin

Net promoter score (NPS) is a market research metric that is based on a single survey question asking respondents to rate the likelihood that they would recommend a company, product, or a service to a friend or colleague. Read more at wikipedia.org/wiki/Net_promoter_score

This widget implements the functionality to ask and collect users the feedback using the typical 0 to 10 scale.

Usage:

final NPS nps = new NPS();
add(nps);

// Get the score and remove component
nps.addValueChangeListener(e -> {
    replace(nps, 
        new Paragraph("You gave "+e.getValue()+". Thank you for your feedback."));
});

There is also a runnable Spring Boot application you can use as starting point for your own NPS collection. Find out more in GitHub repository.

Sample code

final NPS nps = new NPS();
add(nps);
nps.addValueChangeListener(e -> {
    Notification.show("Value changed from " + e.getOldValue() + " to " + e.getValue());
});
