HTML Minifier Next 7 Is ESM-Only

HTML Minifier Next 7 is out—and the title gives it away, it drops support for CommonJS and is ESM-only now.

The update includes another breaking though very specific change:

removeStyleLinkTypeAttributes and removeScriptTypeAttributes have been so closely related (in spirit), they were merged into one option, removeDefaultTypeAttributes.

In CommonJS environments on Node.js older than 22, keep using HTML Minifier Next 6—I don’t maintain old versions, but HMN 6 has been regularly updated and is still in good shape (from all I know 🙂).

For the type-related changes, no action is needed if you don’t use either option; preset output is not affected, as both the conservative and the comprehensive preset had the two options enabled.

(The update includes a few more improvements, but these are the two most important ones.)

As always, if you run into any problem (or have an idea for a feature), report it in the HTML Minifier Next repo. Cheers!

About Me

I’m Jens (long: Jens Oliver Meiert), and I’m an engineering lead, guerrilla philosopher, and indie publisher. I’ve worked as a technical lead and engineering manager at various companies (e.g., Google); I’m an active web and tool developer (code optimization, digital defense), a contributor to web standards (like HTML, CSS, WCAG), and a book author (O’Reilly, Frontend Dogma).

I love trying things—in web development and engineering management, but also in politics and philosophy, where I hold to one idea in particular: that we can only be well if we take good care of everyone. Here on meiert.com I talk about some of my perspectives and experiences. (Please share feedback: Interpret charitably, keep it friendly, but do be critical.)
