This is bundled with @11ty/eleventy (and you do not need to install it separately) in Eleventy v2.0.

Eleventy Dev Server now also 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.

# Serve the current directory
npx @11ty/eleventy-dev-server

# Serve a different subdirectory (also aliased as --input)
npx @11ty/eleventy-dev-server --dir=_site

# Disable the `domdiff` feature
npx @11ty/eleventy-dev-server --domdiff=false

# Full command list in the Help
npx @11ty/eleventy-dev-server --help

npm run test

• We use the ava JavaScript test runner (Assertions documentation)
