What is @types/trusted-types?
The @types/trusted-types npm package provides TypeScript type definitions for the Trusted Types API, which is a web security standard aimed at preventing Cross-Site Scripting (XSS) by restricting access to potentially dangerous DOM APIs. These type definitions allow developers to use Trusted Types in TypeScript projects with type checking and IntelliSense support.
What are @types/trusted-types's main functionalities?
Type Definitions for Trusted Types
This feature provides TypeScript type definitions for creating and manipulating Trusted Types, such as TrustedHTML, TrustedScript, and TrustedURL. The code sample demonstrates how to create a TrustedHTML type using a Trusted Types policy.
import { TrustedHTML, TrustedScriptURL } from 'trusted-types';
function createTrustedTypes(policyName: string): TrustedHTML {
const policy = trustedTypes.createPolicy(policyName, {
createHTML: (input) => input
});
return policy.createHTML('<div>Safe Content</div>');
}
Other packages similar to @types/trusted-types
@types/xss
Provides TypeScript definitions for the xss package, which is a library to sanitize input to prevent XSS attacks. Unlike @types/trusted-types, which is focused on type definitions for the Trusted Types API, @types/xss provides types for a library that sanitizes potentially dangerous user input.
dompurify
DOMPurify is a library that sanitizes HTML and prevents XSS attacks. It does not have a dedicated TypeScript types package like @types/trusted-types, but it can be used in conjunction with @types/dompurify to achieve similar goals in terms of preventing XSS, albeit through sanitization rather than enforcing type safety.
