My Time-Tested, Production-Ready Node.js Setup That Serves 6 Billion Requests Daily
1 min read
Summary
The author presents their efficient Node.js system serving six billion requests daily and optimised for scalability, maintainability and security
Three core practices include static typing with TypeScript, comprehensive testing using Jest or Mocha and Chai with 85% code coverage, and stringent security measures including rate limiting and the use of Helmet to add security headers to Express apps
Static typing helps catch errors early in the development cycle, while comprehensive testing compensates for situations that cannot be caught through static typing, emulating various scenarios a system may face in the real world
Security is a non-negotiable aspect of the author’s development process, with SSL/TLS certificates like Let’s Encrypt and AWS ACM used to enforce HTTPS, and techniques to protect against DDoS attacks and cybersecurity threats.
The setup reflects the author’s personal preferences and will be adapted to the project’s needs, with the usage of AWS WAF shown as an example of a comprehensive rate limiting and security solution.
