pa11y-lambda

Run pa11y scans on AWS Lambda.

Quickstart

Upload to Lambda

Download pa11y-lambda.zip from the releases page, upload to AWS Lambda, and you're good to go.

When you test/run the function, the event payload should resemble what's found in app/run.js:

var event = {
  url: '18f.gsa.gov',
  pa11yOptions: {
    standard: 'WCAG2AA'
  }
}

The handler should be configured to be index.handler.
