Typia is a compile-time code generator that transforms TypeScript type annotations into runtime validation, serialization, and schema functions without requiring decorators or separate schema files. It generates optimized validation and serialization code during TypeScript compilation, producing dedicated functions for each type that eliminate runtime schema objects for faster execution. The project extends this core capability into several integrated areas. It generates fully typed client SDKs from NestJS controller source code, keeping server and client types synchronized automatically. It

js-xss ist ein HTML-XSS-Sanitizer und ein auf Whitelists basierender HTML-Filter, der darauf ausgelegt ist, bösartigen Code aus nicht vertrauenswürdigem HTML zu entfernen. Es dient als Tool zur Prävention von Cross-Site-Scripting und zur Verwaltung von benutzergenerierten Inhalten durch das Bereinigen von HTML-Strings, um ein sicheres Rendering im Browser zu gewährleisten. Die Bibliothek enthält einen CSS-Style-Validator, um Inline-Styles gegen eine Whitelist zu prüfen, sowie einen HTML-Content-Purifier, der in der Lage ist, alle Tags zu entfernen, um rohen Text zu extrahieren. Sie ermöglicht benutzerdefinierte HTML-Filterung durch die Definition spezifischer Regeln und Handler-Funktionen, um erlaubte Elemente und Attribute zu kontrollieren. Das Tool deckt ein breites Spektrum an Sanitization-Funktionen ab, einschließlich Attribut- und Tag-Präfix-Filterung, Entfernung nicht erlaubter Inhalte und Verfolgung entfernter Elemente. Es bietet zudem Mechanismen für zeichenbasierte Escape-Kodierung und benutzerdefinierte Elementbehandlung über Callback-Funktionen. CLI-Dienstprogramme sind für die Verarbeitung von HTML-Dateien und das interaktive Testen von Filterregeln verfügbar.

This is an HTML sanitization library designed to remove dangerous tags and attributes from user-submitted HTML to prevent cross-site scripting attacks. It functions as a content filter that whitelists specific elements and attributes while escaping or discarding unauthorized markup. The project includes an HTML transformation engine that allows for the modification or replacement of tags and attributes using custom logic. It also features a CSS style validator to clean inline properties against permitted patterns and a system for resource URL validation to restrict hostnames and schemes. The
