  onRequest: {
    "/foo/:name": function({ url, pattern, patternGroups }) {
      // Can return false (to skip), a string (for body content), or object for more advanced processing, e.g.:
      return {
        status: 200,
        headers: {
          "Content-Type": "text/html",
        },
        body: `Hello.`
      };

• Super fast startup times: ~2ms (Macbook Air M1 2020)
• Live reload using WebSockets
  • No page refresh CSS updates
  • dom-diffing updates for HTML (via morphdom)
• https support locally
• Automatic port reassignment when port is already in use.

Standalone CLI

Eleventy Dev Server includes a CLI. The CLI is for standalone (non-Eleventy) use only: separate installation is unnecessary if you’re using this server with @11ty/eleventy.

npm install -g @11ty/eleventy-dev-server

# Alternatively, install locally into your project
npm install @11ty/eleventy-dev-server

This package requires Node 14 or newer.
