First steps with Koa.js

In the realm of web development with Node.js, frameworks play a crucial role in simplifying backend API creation, with Express being the most popular due to its maturity and community support since its inception in 2009. However, Koa.js, developed by the same team behind Express, offers a more lightweight and expressive alternative, focusing on asynchronous functions for easier error handling and code manipulation. This article explores setting up a basic Koa.js project utilizing middleware like koa-router, koa-ejs for template rendering, and axios for API calls, demonstrating the creation of endpoints and the integration of a user-friendly HTML template using Bootstrap. Additionally, it highlights Koa's error handling and logging capabilities with koa-logger and suggests further exploration of Koa's advanced features like CSRF protection and JSON Web Tokens. The guide concludes with a nod to LogRocket, a tool for frontend application monitoring, emphasizing the importance of visibility and performance in increasingly complex frontend environments.
