How to keep Vaadin Flow apps fast when the backend is slow: async server calls and web sockets

[@MakhizaMaluleke]

Been looking for this for months, saved my career

[@sebastiaanb9471]

Thanks for this video! Keep up the good work and again thanks for creating Vaadin ❤

[@andromadusnaruto1544]

I definitely needed this... Thanks @Marcus...

[@xcvgfhbbcv]

Brilliant tutorial!! Thank you very much!

[@yermiecheverria4819]

Excellent! Marcus. Thanks. Just one question, what happen when user change the view before the answer of ListenableFuture?. Greetings from Venezuela.

[@AndreaCravana]

I have the exact same question. Marcus can you give us a hint on this?

[@FilipCodes]

Very helpful. Thanks a lot :)

[@Satscape]

I do like that you can use Web sockets, without doing anything other than @Push and .access the UI, great video! Suggestion for future video, What if the server is gonna take a lot longer, but it knows it has 100 things to do, how would you feed that back to a progress bar percentage?

[@mikelinsi]

Awesome thanks! :D

[@raymondfng]

Just what I want ... Thx

Hi Marcus. Can you tell me how it is possible that your live reload works so fast when you changing the java code ? :-)

[@SangeethSKumar1]

Hey. Could you help me with my use case. i am not getting help from stackoverflow. I am using Vaadin Flow 14. I am having a tab concept page. I am trying to open different instances of same page with dynamic routing so that i can follow template approach for rendering multiple data. But the first instance is getting rendered even when invoking another route. Any way to override this behavior.

how to push notification without opening the browser

[@vaadinofficial]

Web Push notifications are a different thing than the `@Push` annotation which is used to enable 2-way communication between the server and client. It sounds like a good idea for a future video! If you want to send web push notifications, you'll have to use a library like github.com/web-push-libs/webpush-java on the server and handle the registration flow on the client.

I just released a new video on sending web push notifications, you can find it here kzbin.info/www/bejne/g2bWk3qsjJiGaqs
