Excessibility.HTML (Excessibility v0.15.0)

Copy Markdown View Source

HTML parsing, wrapping, and static asset path handling.

This module transforms partial HTML (like LiveView renders or controller responses) into complete, standalone HTML documents suitable for axe-core analysis.

Responsibilities

  • Wrapping partial HTML in complete document structure
  • Extracting <head> content from the Phoenix endpoint
  • Prefixing static asset paths with file:// for local analysis
  • Removing scripts (which can't execute in static snapshots)

This module is used internally by Excessibility.Snapshot and typically doesn't need to be called directly.
