Context
The
@coveo/atomic-a11ypackage provides accessibility tooling for Atomic components — automated WCAG auditing, conformance reporting, and VPAT generation.This is the foundation layer that every other module depends on.
What this PR does
Establishes the shared type system, utility functions, and WCAG reference data that all downstream modules import from. Single source of truth.
Two directories:
src/shared/— TypeScript contracts (A11yReport,CriterionLevel, etc.), type guards, constants, and file I/O helperssrc/data/— WCAG 2.2 reference data (success criteria definitions, axe-core rule→WCAG mappings, criterion metadata), dynamically fetched at build time from the official W3C WCAG 2.2 JSONWCAG criteria generation
Instead of hard-coding the list of WCAG success criteria, a build-time script (
scripts/generate-wcag-criteria.mjs) fetches the authoritative W3C JSON and generatessrc/data/wcag-criteria.ts. This ensures the criteria stay in sync with the official spec without manual maintenance.Run
pnpm generate:wcagto regenerate. The generated file includes all Level A and AA criteria from WCAG 2.2 (55 total — 4.1.1 Parsing is excluded as it is obsolete in WCAG 2.2).PR Chain (2 of 7)
