Building Secure APIs with Hapi.js

Introduction

Modern web applications face an increasing number of threats — from token theft to CSRF to brute-force login attempts. A poorly secured API can compromise the entire ecosystem.

Authentication

In Hapi.js, we can build a simple authentication plugin that validates username/password against a RethinkDB store. Passwords must be hashed with bcrypt or argon2 to prevent leaks from exposing plaintext credentials.

CSRF Protection

Hapi provides built-in mechanisms, but you can also integrate rotating CSRF tokens stored in HttpOnly cookies. Every request must include a valid token to be processed.

JWT Tokens

JWTs should be signed with strong algorithms (HS256/RS256). Expire them quickly, and refresh using secure refresh tokens. Always include iat and exp claims.

Conclusion

By combining hashed passwords, CSRF rotation, and JWT best practices, you create a solid baseline for secure APIs.
