sanitize function

lettersanitizer exposes a sanitize function that uses DOMParser to sanitize the HTML content of messages and returns HTML text.

text is used for fallback text in case of no HTML source being available. Plain text in that case is processed into safe HTML output.

interface SanitizerOptions {
  id?: string;
  dropAllHtmlTags?: boolean;
  rewriteExternalResources?: (url: string) => string;
  rewriteExternalLinks?: (url: string) => string;
  allowedSchemas?: string[];
  preserveCssPriority?: boolean;
  noWrapper?: boolean;
}

function sanitize(html: string, text?: string, options?: SanitizerOptions);
