Inline CSS, JavaScript, and images in a HTML file to distribute a stand-alone HTML document without external dependencies.

You can download binaries from the releases page, or compile from source with go install zgo.at/singlepage/cmd/singlepage@latest, which will put a binary in ~/go/bin/.

Run it with as singlepage file.html > bundled.html or cat file.html | singlepage > bundled.html. There are a bunch of options; use singlepage -help to see the full documentation.

Use the zgo.at/singlepage package if you want to integrate this in a Go program. Also see the API docs: https://godocs.io/zgo.at/singlepage

It uses tdewolff/minify for minification, so please report bugs or other questions there.

There are a few reasons:

• Sometimes distributing a single HTML document is easier; for example for rendered HTML documentation.

• It makes pages slightly faster to load if your CSS/JS assets are small(-ish); especially on slower connections.

• As a slightly less practical and more ideological point, I liked the web before it became this jumbled mess of obnoxious JavaScript and excessive CSS, and I like the concept of self-contained HTML documents.
