Your frontend is a target. Hackers use it to steal data. You lose user trust when security fails.

Protect your app with these steps.

Handle User Input

• Never trust user data.
• Validate formats.
• Sanitize inputs to stop XSS attacks.
• Do this on the server.

Secure Your Data

• Stop storing tokens in Local Storage.
• Use HttpOnly cookies.
• Use Secure cookies over HTTPS.
• Send only the data your user needs.

Stop CSRF Attacks

• Use unique CSRF tokens.
• Set your cookies to SameSite Lax.
• This stops fake requests.

Manage Libraries

• Third party code has bugs.
• Run npm audit often.
• Remove unused packages.
• Update libraries fast.

Use Browser Policies

• Set a Content Security Policy.
• This stops bad scripts.
• Use X-Frame-Options to stop clickjacking.
• Set X-Content-Type-Options to nosniff.

Secure Your API

• Use HTTPS for all calls.
• Set rate limits on your API.
• Verify permissions on the backend.

Test Your Code

• Use automated scanners.
• Do manual code reviews.
• Pay for penetration testing.

Security is a habit. Keep your app safe.
