Convert text formatting to HTML string // (Replace 'marked.parse' with your custom BH parsing function if utilizing a proprietary package) const rawHtml = marked.parse(rawText) as string; // 2. Sanitize and bypass security trust for Angular template injection const securedHtml: SafeHtml = this.sanitizer.bypassSecurityTrustHtml(rawHtml); return securedHtml; catch (error) console.error('Error during text-to-html conversion:', error); return this.sanitizer.bypassSecurityTrustHtml(' Conversion Error '); Use code with caution.
