`parseURL(html)`

Parse HTML string and return redirect URL string or undefined.

Examples

      <meta http-equiv="refresh" content="0; url=https://example.com/foo.html" />
    </head>
  </html>

`;

const url = parseURL(html);

    <head>
      <title>Test</test>
    </head>
  </html>
`;

const url = parseURL(html);

// url === undefined

CLI

The CLI will parse HTML input from stdin and output the redirect URL if found (it will output nothing if no URL was found).

# HTML from local file
cat index.html | parse-refresh-redirect

# HTML from URL
curl -s "https://adamjarret.github.io" | parse-refresh-redirect

If parse-refresh-redirect is not installed globally, run it with npx (ex. cat index.html | npx parse-refresh-redirect).

The exit code will be 0 if the URL was found, otherwise 1.

The CLI takes no options.
