Ken Sodemann discusses the integration of web components built with Stencil into applications using Webpack, highlighting a specific Stencil Webpack Plugin that simplifies this process. The plugin is particularly beneficial for applications heavily reliant on Webpack, though it's not mandatory for using Stencil components in general. The implementation involves installing the plugin via npm or yarn, importing component collections into the project, and updating the webpack.config.js file to include these components in the build output. Sodemann provides guidance specifically for Angular applications, noting the need to use the CUSTOM_ELEMENTS_SCHEMA and detailing how to modify the webpack configuration. While the plugin is currently tested only with Angular, there are plans to extend its use to other frameworks like Vue or React.
