security

To prevent XSS in TypeScript, sanitize user-generated HTML content using DOMPurify to neutralize harmful scripts before rendering. This strips malicious code, maintaining DOM integrity and protecting web applications from cross-site scripting attacks.

The best way to validate input data in TypeScript is by defining strict schemas with Zod. Zod parses incoming data against your schema, rejecting unexpected inputs and ensuring type safety throughout your application's runtime.

To audit dependencies for vulnerabilities using pnpm, run the package manager's audit command to identify security flaws in your project dependencies. This flags known vulnerabilities, allowing you to update packages and mitigate risks.

To handle sensitive API keys securely in TypeScript, store them in environment variables rather than hardcoding them into your source files. This prevents accidental exposure in version control and isolates sensitive data from application logic.

TypeScript input validation with Zod prevents injection attacks by enforcing strict schema constraints on incoming data. By rejecting malformed payloads at the application boundary, Zod ensures only structurally valid data reaches your logic.
