TOOLID=pwa-manifest-auditor. Validate a local web manifest against a separately exported built-site inventory. Check start URL, scope, icon references and metadata, and separately report what the export says about an offline shell. No browser is driven, no host is resolved, no service worker is run, and no site is changed. Node.js 22+; zero dependencies.

This walkthrough uses the tool's public README and checked-in example files. Run the command from a repository checkout with Node.js 22+.

Run the checked-in example

node bin/pwa-manifest-auditor.mjs --root examples/passing --manifest manifest.webmanifest --site site.json
node bin/pwa-manifest-auditor.mjs --root examples/failing --manifest manifest.webmanifest --site site.json
npm run check

Read the result

The first example exits 0/pass; the second exits 1/fail for a start URL outside scope and an absent icon. --help lists options. JSON is written only to stdout. Input paths are relative to --root; a symlink resolving outside its real directory is refused. There is no output-file option, so input documents cannot be overwritten.
