A simple newsletter subscription form without API rate limiting triggered a cascading production outage on a logistics platform. Unthrottled requests caused database connection exhaustion, depleted third-party email quotas on Resend, and generated costly infrastructure bills. Learn how to implement Redis-backed sliding window rate limiting, decouple email dispatch with message queues & bot. #RateLimiting #SystemDesign #DevOps #SRE #Nodejs #Redis #Cybersecurity #WebSecurity #BackendDevelopment
Cloudflare rebuilt the Workers module registry in workerd to achieve true Node.js and web standards compatibility. By moving from filesystem paths to a URL-based registry, Workers introduces native import.meta, validated import attributes, synchronous require(esm), lazy compilation, and 64MB bundle support. Learn how to configure the new module engine. #CloudflareWorkers #Nodejs #Serverless #JavaScript #WebDev #EdgeComputing #Workerd #V8Engine #DevOps #SoftwareArchitecture
Distributed systems frequently suffer from data inconsistencies when updating a database and publishing message events simultaneously. The dual-write problem leads to lost events or ghost records during system crashes. This technical guide demonstrates how to implement the Transactional Outbox Pattern in Node.js with PostgreSQL and RabbitMQ. #Nodejs #Microservices #Database #SystemDesign #OutboxPattern #PostgreSQL #Kafka #RabbitMQ #Backend #Architecture
Integrating payment gateways into distributed microservices requires decoupled communication models and strict protocol separation. This technical guide explains how to implement PayPal in a microservices architecture using NestJS, gRPC, and Docker. Learn Proto contracts, run dual HTTP and gRPC transport layers in a single process, handle PayPal v2 checkout orders, and orchestrate containerized services. #NestJS #gRPC #Microservices #Docker #PayPal #Backend #Nodejs #APIs #SoftwareArchitecture
Traditional logging is broken for modern microservices. Scattering disconnected string logs across distributed systems leads to context fragmentation and expensive telemetry bills. This technical guide explains how to transition from legacy log statements to Wide Events and Tail Sampling. Learn how high-cardinality, high-dimensionality event records restore visibility and cut storage overhead. #Observability #DevOps #SRE #Logging #DistributedSystems #OpenTelemetry #WideEvents #FinOps #Backend
