eleventy-plugin-components v1.0.3

eleventy-plugin-components

One of many approaches to using js components in eleventy

Install

npm install eleventy-plugin-components

Usage

in .eleventy.js

const components = require('eleventy-plugin-components')

module.exports = eleventyConfig => {
  eleventyConfig.addPlugin(components)
}

Create components as named iife in _site/js. In the example setup, we have a counter component like this

As the name implies it is a counter. It also takes a name property and shows a string with Hello ${name}.

To use the component in a markdown page use a code block with comp as language and the following content:

name: counter
className: counter
props:
  name: world
fallback: If you enable js, you will see a counter here

• name is the name of the component
• className is a class we add to the <div> that contains the component (for styling)
• props is what we pass the component, in this case a name
• fallback is what you see if you disable javascript

only name is required, the rest is optional.

What does this plugin do?

• It replaces your code block with a <div> with a unique id
• and a class if you defined it with className
• adds a script tag loading your component
• adds another script tag that removes the content (the fallback text) and calls your component giving it the unique id and the props

See the example markdown and the generated HTML file

Things to be aware of

• Your component must be a function taking an id as first arguments and properties as a second (see the example component)
• How the component is built is up to you (see the example build script for inspiration)
• The build component has to be an iife with the same name as name but in CamelCase (a component folder my-beautiful-component needs to have a global name MyBeautifulComponent)
