Demo Component: Hello World

This very basic component will display a "Hello World" banner 1 second after load.

Using the Generator

Eleventy (11ty) is a static site generator that makes it possible to mix templating languages. More importantly to this generator is that we can customize the output file type and composite a file from includes.

The web components are generated within a Nunjucks (.njk) template that outputs the final .js file.

This generator works with the inherent features of Eleventy, including that it expects templates and template partials to be placed in _includes.

This leads to the following file structure to create a web component with styles and additional scripting.

First, create the component template file in src/components/[component-name].njk. It is important to kebab-case the file name

Then within _includes/components/ create:


Keep the names of script.js and style.css so that the _includes/component.njk template can successfully include their contents to generate the web component.

Using a Generated Web Component

The final web component will be output within public/components/[component-name].js and is ready to be included in another project such as:

<script type="module" src="path/to/component-name.js"></script>

Display a Component Within This Generator Project

Create additional pages in this project directly within src as Nunjuck (.njk) files and add the following frontmatter in addition to any HTML and Nunjuck template tags.

title: Page Title
component: component-name

Then the page.njk template will use the component value to include the relative path to the web component script.

Web Component Resources

First a little disclaimer - I am brand new to web components, so I know this doesn't cover all the things you may want to do, or the best way to generically composite them. Submit a PR if you want to help extend this generator!

Here are some resources that helped me put together my first web component:
