Can anyone show me how to create a side menu in Vaadin 13?
I’ve tried it with the normal App layout, but I can’t put it to the side like I want it.
You could try this awesome Addon from the vaadin directory:
https://vaadin.com/directory/component/app-layout-add-on
It's a responsive Sidebar.
You just need to add following dependency in your pom.xml:
<dependency>
<groupId>com.github.appreciated</groupId>
<artifactId>app-layout-addon</artifactId>
<version>1.0.2</version>
</dependency>
Under https://github.com/appreciated/vaadin-app-layout you can find some example code.

I have a working vaadin-8 application. I want to migrate this application to vaadin-23.I have added dependencies related to vaadin-23
<dependency>
<groupId>com.vaadin</groupId>
<artifactId>vaadin-bom</artifactId>
<version>${vaadin23.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
i am able to create views based on vaadin-23. But the problem is my vaadin-23 views with #Route annotation are not being used. I am not able to hit those urls from the browser. Do I need to create some servlet for vaadin-23 as I did for vaadin-8?
If the application is not using Spring check this example project for step by step migration from Vaadin 8 to Vaadin 14 running both apps at the same time in the same workspace. Scenario with Vaadin 23 should not be different regarding project setup. github.com/TatuLund/migrate-v8-to-v14/tree/master
But if you use Spring Boot, that is most likely the case. Both Vaadin versions require different version of the Spring add-ons, and those in turn define new scopes and there will be a clash.
In such case one can always deploy two different wars either on different context paths or different ports. Naturally you should keep the projects separated and use different IDE instance for each one. But if your requirement is to keep two apps running on the same server, so that it is easy to switch between them, it will work for that purpose.
Tried embedding this JS code into the UI: https://www.w3schools.com/html/html5_geolocation.asp but nothing happens.
Is there any way to achieve this in a Vaadin 8 app?
There couple of approaches to do this in Vaadin 8. In both cases you need to create custom component with client side part. The component can be based on GWT or be JavaScript component. In case of GWT based component, you need to use native JavaScript blocks. There is good example of that here in this GitHub repository:
https://github.com/heruan/vaadin-geolocation/blob/master/geolocation-addon/src/main/java/com/vaadin/addon/geolocation/client/GeolocationConnector.java
The above implementation has been released as an GeoLocation add-on in Vaadin Directory. So you do not need to re-invent the wheel, if you do not want to.
I've just created a vaadin application, the simplest one you can create, and I was wondering, how do I find out if I have a theme in it and which one it is? The reason for that is that I'm deploying my application to Jenkins and it doesn't like something in my pom.xml file, which I commented out:
compile-theme</goal> -->
With this commented out it works but I need to now whether it is safe to do so. I know that if I don't have a theme it's OK to do it, but I'm trying to find out whether I do have a theme. My understanding is that a theme should be inluded to the pom.xml file under but I can't find any there:
<properties>
<vaadin.version>7.6.5</vaadin.version>
<vaadin.plugin.version>${vaadin.version}</vaadin.plugin.version>
<jetty.plugin.version>9.2.3.v20140905</jetty.plugin.version>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.source>1.7</maven.compiler.source>
<maven.compiler.target>1.7</maven.compiler.target>
</properties>
Does it mean that I'm not using any theme?
thanks
Specifying the theme for a Vaadin application can be done with the #Theme annotation on your UI class:
#Theme("demo")
public class DemoUI extends UI {
...
The theme is not configured in your build configuration (pom.xml).
If you do not specify a theme to be used anywhere, Vaadin will transparently use a default theme (reindeer or valo). So every Vaadin app will use a theme even if it is not specifically configured.
If you want to check the theme which is currently used by your Vaadin application, you can do so using the debug mode. Open the debug window and activate the general info tab. There you can see the currently active theme, the used widget set, the current Vaadin version and more.
Regarding the compile-theme goal in your build configuration: It is safe to comment this goal out as long as you don't use a custom theme which needs compiling. If you use one of Vaadin's built-in themes, you don't need this goal to be active. Check the documentation about Vaadin themes for details.
Hope you are fine and doing good.

Inshort my question is how can i create webpage from PSD to HTML using vaadin
The Vaadin framework has changed a lot over the last few years, just be careful in searching for answers that you get the latest information. The Book of Vaadin is a great place to start. The Demo Sampler also gives you code examples (the icons in Menu provide various code details).
I am trying to follow this tutorial to create DropWizard views. However, when I try to addBundle(new ViewBundle()), it fails to find (or import) ViewBundle. What am I missing here?
The dependency dropwizard-views was missing in my maven pom file. Adding the dependency solved the issue.
<dependency>
<groupId>io.dropwizard</groupId>
<artifactId>dropwizard-views</artifactId>
<version>${dropwizard.version}</version>
</dependency>
You will need to choose one of the view template. As of writing, Dropwizard supports FreeMarker and Mustache. Instead of including dropwizard-view dependency, you should choose either dropwizard-views-mustache or dropwizard-views-freemarker, and dropwizard-view will be included as dependency.
