Formentry android5/11/2023 Let’s copy the stylesheet: cp dist/angular-web-component/styles.*.css example/info-box.cssĪngular builds multiple JavaScript files and a style file. In this directory, we’re going to have an index.html file and it’s going to contain the info-box.js JavaScript file that we produced, along with the info-box.css stylesheet. We begin our new standalone project by creating a new example directory at the project’s top-level. Now that we have a production build of our Angular component, we can use it as a web component in another project. So let’s build the project: ng build -prod The major difference is that the app component no longer exists and it is the index.html that renders our embeddable web component. We run ng serve for local development and ng build -prod. Building the projectīuilding a web component project is similar to what we do for a typical Angular project. Also notice that we specify the CUSTOM_ELEMENTS_SCHEMA, which is provided by The ngDoBootstrap method is also required to kickstart the Angular rendering process. The constructor code is the replacement for the bootstrap configuration. ![]() We’re going to change the selector from the generated “app-info-box” to “info-box”, and add two input attributes to the info box component’s code: // src/app/info-box/ This will generate the component’s TypeScript code, HTML template, and CSS stylesheet. Run the following command in the root project directory: ng generate component info-box We will add a new component which we will turn into an embeddable widget. Creating the newsletter signup form component For styling the component, we’re going to keep things simple and use CSS (alternatives that Angular allows are SCSS, Sass, Less, and Stylus). We’re also going to skip out on generating tests. We don’t need any routing for our demonstration. Then, we create a new Angular workspace which will contain our app: ng new angular-web-component -routing=false -skip-tests=true -style=css We start by installing the Angular CLI globally: npm install -g the Angular project After that, we’ll make sure the widget works with the usual Angular build process. You can view the finished code on Github.Ĭreating a simple Angular widget componentįirst, we’re going to create a new Angular app and a simple widget. In this article, I’ll show you how to use Angular to build an embeddable newsletter signup form that uses Web Components. ![]() With Angular, you can already do that through templates where component selectors are used to place the Angular component into the DOM. The idea is that you can put something like next to standard elements, like and, and it will just work. The goal for web browsers, such as Google and Mozilla, is to provide a standardized way for developers to create custom elements with any framework. Web components are a way of creating custom elements that work alongside the standard HTML elements.
