Eleventy plugin to bundle your scripts and styles
This plugin is contributed by Internet 2000 web studio, it is used to create green websites with Silex website builder
- The plugin on npm (
@silexlabs/eleventy-plugin-concat) - Github repo
- Add the plugin to your
.eleventy.jsconfig - Add
data-concatattribute to<script>,<script src=,<style>and<link rel="stylesheet" href=which are in the page<head> - After the site has been built by eleventy, the plugin will write new
script.jsandstyle.cssfiles with the content of all the scripts and styles withdata-concat - The plugin will also change you HTML to load the new script and style in place of the old ones
Tip: this plugin works great with eleventy-plugin-helmet which makes it easy to group scripts of templates in HEAD
This is the roadmap and feature list:
- Transform all generated pages after the build
- Concat inline scripts
- Concat loaded scripts from base url and get their content from file system
- Concat loaded third-party scripts and fetch their content
- Concat inline styles
- Concat loaded stylesheets from base url and get their content from file system
- Concat loaded third-party stylesheets and fetch their content
page.njk (also works with liquid or other template language):
<!doctype html>
<html>
<head>
<script src="/site.js" data-concat></script>
<script src="/page.js" data-concat></script>
<script data-concat>
console.log('concat')
</script>
<link rel="stylesheet" href="/site.css" data-concat />
<link rel="stylesheet" href="/page.css" data-concat />
<style data-concat>
body { background: blue; }
</style>
</head>
</html>Generated _site/page.html:
