A deep dive into decoupling Next.js 16, NestJS, LangGraph, and Redis Streams into an elastic, pay-for-what-you-compute mental health engine. Most modern AI applications follow an intuitive, straightforward pattern: the browser sends an HTTP POST, the API server invokes an LLM SDK, waits 15 seconds while streaming chunks back over the wire, and saves the result […]
Read ArticleCompetitive programming is one of the best ways to improve your problem-solving skills, learn algorithms and data structures, and become more confident at writing code under constraints. Whether you are a beginner learning programming, a computer science student preparing for coding interviews, or an experienced developer looking to sharpen your algorithmic thinking, regularly solving coding […]
Read ArticleWhen developing web applications, you might notice that before a POST request is sent, your browser first sends an OPTIONS request. This behavior is often confusing, especially when working with CORS (Cross-Origin Resource Sharing) and different types of requests. So, why does your client always send an OPTIONS request before a POST, and when does […]
Read ArticleWhen working with web development and server-side interactions, it’s common to encounter different HTTP methods like GET, POST, and OPTIONS. Each of these methods serves a specific purpose, and understanding how they work is essential for creating efficient web applications. In this post, we’ll explore what an OPTIONS request is, how it differs from GET […]
Read ArticleIn the world of distributed systems, designing applications that are robust, responsive, and reliable is a complex challenge. One of the fundamental principles guiding these designs is the CAP theorem, which states that a distributed data store can only provide two out of the following three guarantees: Consistency, Availability, and Partition Tolerance But why ? […]
