Polymer is a Python library typically used in Server, Runtime Evironment, Nodejs applications. Polymer has no bugs, it has no vulnerabilities, it has build file available and it has low support. You can download it from GitHub.

It's something a bit like an email client. More accurately, it's something a bit like an email client would have been, if it had been written using state-of-the-art technology, circa 1997, and then kept up with everything. Except Python didn't exist, then. It's intended to be as fast as buggery, and handle vast mailboxes precisely as fast as small ones.

            Vaadin Designer Tabs not correctly adding children "tab" to tabs object
            Asked 2021-Jun-05 at 10:38

            I'm using Vaadin Deisgner 14.6.1 to create some super simple tabs. However, when I try to do some simple operations in the java class (eg selecting a tab), it throws an error which indicates that the "Tabs" object does not have the proper children "tab" components. Here's a simple test case below. (I discovered the issue when I was trying to add a addSelectedChangeListener() to the tabs class and discovered that it would never fire, presumably since the "tabs" class never properly had any children.) I tried a bunch of hacks, but nothing worked. (I have in the past gotten tabs to work if I stuck purely to a programmatic approach, but I really really really like using Designer, since it saves me tonnes of times and keeps the code quite modular and clean....when it works....)



            Answered 2021-Jun-05 at 10:38

            This is an unfortunate limitation of the component mapping to elements defined in a template. When mapping to Java, the parent-child relationships are not preserved and thus the tabs component does not realize that the tab is one of its child components.

            See https://github.com/vaadin/flow/issues/7622

            The way to make it work would be to create the Tabs and Tab instances in Java and the rest in Designer.

            child property from parent Promise
            Asked 2021-Jun-02 at 12:30

            I want to create a navigation component for my project. The shell fetches a json with chapter info, these are passed to nav-element, which recursively calls itself to render the navigation tree.




            Answered 2021-Apr-17 at 07:22

            There is a time frame between the construction of NavElement and the assignment of the chapters property where chapters is undefined. It might be safe to initialize chapters in the component itself rather than in Shell's until directive, or at least provide a fallback value in the template:

            Web components community polymer web components
            Asked 2021-May-17 at 17:18

            If I look at the polymer shop I am instantly sold on wanting to use this as a starter for my web shop. Not just because it's already a web shop (full pwa technology) but because it has excellent (offline) experience on browser/mobile, has proper documentation and is still maintained.

            But then look at the polymer home page and see the project is based on an outdated polymer version and even the fact that it's using polymer in the first place is curious:

            The Polymer library is in maintenance mode. For new development, we recommend Lit.

            So my question is if lit will have the rich choice of web components that the shop seems to be depending on?

            This may be a dumb question but I skipped polymer other than looking at some exciting news in google IO



            Answered 2021-May-17 at 17:18

            The goal of Lit, and of Polymer before it, is to help build web components and applications using browser features as much as possible.

            For instance jQuery wrapped all the different browser features in it's own syntax, to the point where developers were learning jQuery, rather than Javascript. jQuery components assume that you have jQuery and rely on those jQuery methods to function.

            Both Lit and Polymer championed web components - this makes each component much more self-contained. Using a mix of jQuery and any of its competitors was really painful, but that isn't the case here.

            All the components used to build that shop are stable and still on npm. You can use them if you want and I have live applications that still use them.

            However, championing the latest browser features has its risks. Polymer relied heavily on HTML Imports (that only Chrome ever implemented and were ultimately dropped) and its own template library. It was ultimately ported to ES6 modules, but the core design is far less suited to it. Those components are pretty stable, but you don't really want to start anything new with it.

            Lit is quite a lot less opinionated than Polymer, and much lower level. For instance Polymer supported two way binding with {{property}} syntax, but had to make assumptions (that often broke) about what you were doing to support it. Lit drops that for extremely stable property setters but if you want to users to write values you have to subscribe to events and roll that yourself (Lit does make events very easy to manage though).

            So if you're going to build your own web components or application Lit is by far the better choice, and LitElement is lightweight and extremely compatible with everything else. You can use those Polymer shop components in Lit (I have) but for most of them there are newer alternatives, in particular MWC.

            Azure Web App not updating after mvn azure-webapp:deploy
            Asked 2021-May-05 at 20:40

            I'm using Azure to host my Java Spring Boot application. I have created a trial to test this solution and I managed to deploy my application following this tutorial Deploy with Azure which is using the azure-webapp-maven-plugin and the command mvn azure-webapp:deploy.

            My problem is that when I'm making changes inside my application and I want to apply them in my Azure Web App but nothing actually update when I reach the page, here is the message after using the deploy command :



            Answered 2021-May-05 at 20:40

            Are you only running mvn azure-webapp:deploy?

            Make sure you run mvn package first, or mvn package azure-webapp:deploy. Otherwise it will just re-deploy the same WAR file. Include the -Pproduction flag if you want to run it in production mode.


            I set up a project myself and could reproduce your issue. After running mvn azure-webapp:config again twice and updating both Application and Runtime, it seems to work.

            This did two changes to the pom.xml, try these out:

            1. Add war under in the azure-webapp-maven-plugin.
            2. Change jre8 to TOMCAT 9.0.

            Bridge pattern: how to define functions that call the implementation of the derived class
            Asked 2021-Mar-30 at 12:39

            I am working on a polymer simulation code that employs the Bridge pattern to separate abstractions (the objects involved in the simulation) and their implementations (how they are represented e.g. one particle per monomer, continuous grid, etc.). A problem that I am facing is that I am struggling to define a class hierarchy of abstractions where lower abstractions can execute functions defined on other classes higher up in the hierarchy.

            I would like to define a base abstraction Monomer that incorporates a number of methods that call the MonomerImpl implementation. Say, a method applyDisplacement to move the monomer in space. However, when I define a derived abstraction MonomerTypeA with several implementations MonomerTypeAImplGrid, MonomerTypeAImplParticles, etc., I would like to call applyDisplacement, defined at the top of the hierarchy class, but using the specific implementation of my monomer class.

            This is an example of what I have tried:

            Implementing outside clicks on Lit-Elements
            Asked 2021-Mar-10 at 16:46

            I'm making a custom dropdown web component using LitElements and while implementing the click-outside-dropwdown-to-close feature I'm noticing some unexpected behavior that is blocking me. Below in the async firstUpdated() function I'm creating the event listener as recommended in their documentation. Logging out dropdown works as expected, but logging out target returns the root ... element every time, which while accurate to an extent, is not specific enough. If there's a better way to handle outside click events I'm all ears.

            For reference, here's something that's already built (although the source is hidden) that I'm trying to replicate: https://www.carbondesignsystem.com/components/dropdown/code/



            Answered 2021-Mar-10 at 16:46

            The click event's target property is set to the topmost event target.

            The topmost event target MUST be the element highest in the rendering order which is capable of being an event target.

            Because a shadow DOM encapsulates its internal structure, the event is retargeted to the host element. In your example, the click event's target is retargeted to the custom-drop-down because that is the first and highest element capable of being a target.

            If you need to target an element inside your custom element, you can take one of the following approaches:

            1. Register an event listener inside your element.
            2. Use the element to fill your custom element with elements that are declared in the light DOM.
            3. Use the composedPath on events with composed: true to determine which internal element your event bubbled from.

            Here's an example of the functionality I believe you are looking for. If you click on the Custom Element it toggles its active state (similar to toggling a dropdown). If you click on any other element on the page, the custom element deactivates itself (similar to hiding a dropdown when it loses focus).

            List and filter from data model based on user selection - SwiftUI
            Asked 2021-Feb-26 at 20:40


            I have 3 lists in 3 VStacks based from a data model.

            1. Categories
            2. Applications
            3. Products

            The idea is that when the user selects a category, it filters through the application list and only displays applications that are found in the same data model. Then when the user selects an application from the second list, it would only list products found in the same data model into the third column.


            I am struggling to filter and list the applications based on the selected category. Once I know how to do that I am assuming I can use the same method to filter the final products column.




            Answered 2021-Feb-26 at 20:40

            The .contains method will work well for your usage. You can filter the products based on whether or not their categories or applications contain a selected item.

            I also used a couple of other techniques from your original code, like using Set to filter out duplicate elements and your sorted method to put All at the top (I moved it to its own extension to be able to reuse it).

            Using Bind to a property from LitElement in React
            Asked 2021-Feb-22 at 14:58

            I have a web component library built using litElement. We are using these components in a React project and are running into an issue using some of the property binding attribute features. React is throwing an error when using the below syntax.

            Property binding examples can be seen here using
            .attr="" and ?attr=""

            Is there a way to use these property bindings inside a React app with a prefixed "." or "?". I am currently aware that we can use JSON.stringify to pass objects as a string to the attribute but would rather pass the objects as a property vs an attribute.



            Answered 2021-Feb-18 at 09:31

            Is there a way to use these property bindings inside a React app with a prefixed "." or "?"

            Short answer: no.

            The first reason is that those syntaxes are lit-specific constructs that you can only use in its rendering context (inside the template of the WebComponent). The other bad news is that React's peculiar view of DOM and rendering make it one of the most WC-incompatible frameworks: you'll have to rely on attributes and refs to communicate with your web components, no property and event binding.

            How to properly stub an element when unit testing a LitElement component?
            Asked 2021-Feb-19 at 12:06

            I'm trying to unit test LitElement components. When trying to isolate components, I got perplexed how to actually stub elements. That is, I cannot find a solution how to replace a proper element with a hollowed one.
            The polymer project on the topic of unit testing mentions this I failed to find the definition of the replace() function to see the implementation details. Actually, what is described by the polymer project in the "Create Stub Elements" heading is what I'm looking for.

            Element definition file



            Answered 2021-Feb-19 at 12:06

            The first error is likely caused by being defined twice in the two versions. This is not avoidable since as of now custom elements are not un-definable (and thus re-definable with a different class). Removing the registration call as you tried doesn't solve the problem because the component would still be created using the original class.

            The simplest solution would be to use a different tag name (even the Polymer docs you cited do this). If you really need the tag names to be the same then what I can suggest is to only replace some properties/methods of the original class. OpenWC and Modern Web testing guides have some parts (1, 2) dedicated to this.
