api-security-best-practices

JWT authentication for API endpoints is implemented using the jsonwebtoken dependency alongside bcrypt for password hashing to secure user credentials. This Skill provides patterns to integrate these libraries into JavaScript and Express.js applications.

Preventing SQL injection and XSS in an API requires strict input validation and data sanitization. This Skill implements validation patterns that filter malicious payloads before they reach your backend logic or database queries.

Rate limiting protects against brute force and DDoS attacks by restricting the number of requests a client can make within a specific timeframe. This Skill uses the express-rate-limit dependency to throttle traffic and block abusive IPs.

Role-based access control in Express.js is supported through the Skill's authorization features. It allows you to define user permissions and restrict access to specific API routes based on assigned roles.

Prior knowledge of API security best practices and familiarity with JavaScript and Express.js is required. The Skill provides advanced implementation patterns for authentication and data protection rather than introductory concepts.

Securing sensitive data with encryption in transit and at rest is handled through the Skill's data protection mechanisms. It applies cryptographic standards to safeguard API payloads and stored information from unauthorized access.
