+# Leptos Axum JS SSR Example
+
+This example shows the various ways that JavaScript may be included into
+a Leptos application.  The intent is to demonstrate how this may be done
+and how it may cause the application to fail in an unexpected manner if
+done incorrectly.
+
+## Quick Start
+
+Run `cargo leptos watch` to run this example.

+
+**Note: this contains only a subset of files from the full package from NPM.**
+
+[![install size](https://packagephobia.now.sh/badge?p=highlight.js)](https://packagephobia.now.sh/result?p=highlight.js)
+
+**This package contains only the CDN build assets of highlight.js.**
+
+This may be what you want if you'd like to install the pre-built distributable highlight.js client-side assets via NPM. If you're wanting to use highlight.js mainly on the server-side you likely want the [highlight.js][1] package instead.
+
+To access these files via CDN:<br>
+https://cdn.jsdelivr.net/gh/highlightjs/cdn-release@latest/build/
+
+**If you just want a single .js file with the common languages built-in:
+<https://cdn.jsdelivr.net/gh/highlightjs/cdn-release@latest/build/highlight.min.js>**
+

+
+## Highlight.js
+
+Highlight.js is a syntax highlighter written in JavaScript. It works in
+the browser as well as on the server. It works with pretty much any
+markup, doesn’t depend on any framework, and has automatic language
+detection.
