Arguments:
--version

Input template files (default: \`.\`)

Write HTML output to this folder (default: \`_site\`)
--serve
Run web server on --port (default 8080) and watch them too
--port
Run the --serve web server on this port (default 8080)
--watch
Wait for files to change and automatically rewrite (no web server)
--incremental
Only build the files that have changed. Best with watch/serve.
--incremental=filename.md
Does not require watch/serve. Run an incremental build targeting a single file.
--ignore-initial
Start without a build; build when files change. Works best with watch/serve/incremental.
--formats=liquid,md
Allow only certain template types (default: \`*\`)
--quiet
Don’t print all written files (off by default)
--config=filename.js
Override the eleventy config file path (default: \`.eleventy.js\`)
--pathprefix='/'
Change all url template filters to use this subdirectory.
--dryrun
Don’t write any files. Useful in DEBUG mode, for example: \`DEBUG=Eleventy* npx @11ty/eleventy --dryrun\`
--loader
Set to "esm" to force ESM mode, "cjs" to force CommonJS mode, or "auto" (default) to infer it from package.json.
--to=json
--to=ndjson
Change the output to JSON or NDJSON (default: \`fs\`)
