hx-complete

This extension provides Visual Studio Code with auto-completion support for HTMX's v2 HTML attributes. It accomplishes this by contributing custom data to VS Code's HTML language service.

Because this extension contributes to only this language service, it does not provide support for programming language or templating language file types. For example, VS Code will not understand that your .js, .cshtml, and .jinja files may contain HTMX attributes just because you installed this extension.

Why this extension?

v2 attribute support

This extension supports HTMX v2 while some of the other available extensions support HTMX v1.

I don't think there's anything wrong with that, especially because according to the project homepage:

... It is not currently marked as latest in NPM so that people using the 1.x line are not accidentally upgraded.

data-* attribute support

Unlike other extensions, this one also includes data-* attribute support.

While not highlighted throughout the official documentation, HTMX allows you to use data-hx-* attributes as an alternative to hx-* attributes for the sake of using standard HTML attributes. The feature is mentioned under the "htmx in a Nutshell" section of those docs.

It's worth mentioning that, if you prefer, you can use the data- prefix when using htmx:

<a data-hx-post="/click">Click Me!</a>

Should you install this extension?

Probably if:

• You want HTMX v2 auto-completion support.
• You want that support to include data-* attributes.

Probably not if:

• You are using HTMX v1.
• You need incredibly detailed hover-over documentation.
• You need auto-completion in something other than .html files.

Usage

Just install the extension and start writing HTML with HTMX.
