Common Usage Example

The most common use is probably to run hugo with your current directory being the input directory:

$ hugo
0 draft content
0 future content
99 pages created
0 paginator pages created
16 tags created
0 groups created
in 120 ms

This generates your web site to the public/ directory, ready to be deployed to your web server.

Instant feedback as you develop your web site

If you are working on things and want to see the changes immediately, by default Hugo will watch the filesystem for changes, and rebuild your site as soon as a file is saved:

$ hugo -s ~/Code/hugo/docs
0 draft content
0 future content
99 pages created
0 paginator pages created
16 tags created
0 groups created
in 120 ms
Watching for changes in /Users/spf13/Code/hugo/docs/content
Press Ctrl+C to stop

Hugo can even run a server and create a site preview at the same time! Hugo implements LiveReload technology to automatically reload any open pages in all JavaScript-enabled browsers, including mobile. This is the easiest and most common way to develop a Hugo web site:

$ hugo server -ws ~/Code/hugo/docs
0 draft content
0 future content
99 pages created
0 paginator pages created
16 tags created
0 groups created
in 120 ms
Watching for changes in /Users/spf13/Code/hugo/docs/content
Serving pages from /Users/spf13/Code/hugo/docs/public
Web Server is available at http://localhost:1313/
Press Ctrl+C to stop

Deploying your web site

After running hugo server for local web development, you need to do a final hugo run without the server part of the command to rebuild your site. You may then deploy your site by copying the public/ directory (by FTP, SFTP, WebDAV, Rsync, git push, etc.) to your production web server.

Since Hugo generates a static website, your site can be hosted anywhere, including Heroku, GoDaddy, DreamHost, GitHub Pages, Amazon S3 with CloudFront, Firebase Hosting, or any other cheap (or even free) static web hosting service.

Apache, nginx, IIS… Any web server software would do!

A note about deployment

Running hugo does not remove generated files before building. This means that you should delete your public/ directory (or the directory you specified with -d/--destination) before running the hugo command, or you run the risk of the wrong files (e.g. drafts and/or future posts) being left in the generated site.

An easy way to work around this is to use different directories for development and production.

To start a server that builds draft content (helpful for editing), you can specify a different destination: the dev/ dir.

$ hugo server -wDs ~/Code/hugo/docs -d dev

When the content is ready for publishing, use the default public/ dir:

$ hugo -s ~/Code/hugo/docs

This prevents content you’re not yet ready to share from accidentally becoming available.

Alternatively, serve your web site with Hugo!

Yes, that’s right! Because Hugo is so blazingly fast both in web site creation and in web serving (thanks to its concurrent and multi-threaded design and its Go heritage), some users actually prefer using Hugo itself to serve their web site on their production server!

No other web server software (Apache, nginx, IIS…) is necessary.

Here is the command:

$ hugo server --baseURL=http://yoursite.org/ \
              --port=80 \
              --appendPort=false \
              --bind=87.245.198.50

Note the bind option, which is the interface to which the server will bind (defaults to 127.0.0.1: fine for most development use cases). Some hosts, such as Amazon Web Services, run NAT (network address translation); sometimes it can be hard to figure out the actual IP address. Using --bind=0.0.0.0 will bind to all interfaces.

This way, you may actually deploy just the source files, and Hugo on your server will generate the resulting web site on-the-fly and serve them at the same time.

You may optionally add --disableLiveReload=true if you do not want the JavaScript code for LiveReload to be added to your web pages.
