Security

Keep your Vue app secure by sanitizing user input, using HTTPS, and following best practices for authentication and authorization.

Security is essential for protecting your users and data. Here are some best practices to follow:

Tips

Never trust user input
Always validate and sanitize any data coming from users before processing or displaying it.
Use libraries for sanitization
Prevent XSS attacks by sanitizing HTML. Use libraries like DOMPurify:
```
import DOMPurify from "dompurify";
const clean = DOMPurify.sanitize(userInput);
```
Keep dependencies up to date
Regularly update your dependencies to patch known vulnerabilities. Use tools like npm audit:
Terminal window
```
npm audit fix
```
Use HTTPS
Always serve your app over HTTPS to protect data in transit.
Implement proper authentication and authorization
Use secure authentication methods (e.g., OAuth, JWT) and restrict access to sensitive routes and APIs.
Avoid exposing sensitive data
Never store secrets or API keys in your frontend code. Use environment variables and secure backend services.
Set secure HTTP headers
Use headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance security.
