Avoid blocking the event loop, improper error handling, and neglecting security practices. Using outdated dependencies can also pose risks.

Adopt consistent coding styles, document thoroughly, and use modular code architecture. Regularly refactor and update dependencies as part of your Node.js dependency management strategy.

Use ESLint for code consistency, Helmet for security, and Winston for logging. Tools like npm audit help with Node.js dependency management.

Node.js can be integrated using microservices design and development. It communicates well with other systems via RESTful APIs or GraphQL.

Validate and sanitise user input, use HTTPS, and implement proper authentication and authorisation. Follow secure coding practices in Node.js to protect your APIs.

Use tools like PM2 for process management, New Relic for performance monitoring, and Webpack for module bundling. These tools assist with Node.js performance optimisation.

Common vulnerabilities include SQL injection, cross-site scripting (XSS), and insecure dependencies. Adopting Node.js security best practices help mitigate these risks.

Node.js uses V8’s garbage collection for memory management. Efficient coding and monitoring are crucial for Node.js performance optimisation.
