Description

In this project-based course, we will build a complete REST API in Go from scratch and deploy it to the cloud, ready to handle real traffic and scale affordably.Our journey begins by creating a simple TCP server, which will help us explore the net/http package in Go and understand the basics of handling network communication.Next, we’ll dive into the theory behind building reliable and composable Go web applications. From there, we’ll develop our project step-by-step, covering carefully curated topics such as request handling, middleware creation, database integration, request and database optimisations and rate limiting to equip you with the skills needed to ship real backend services to the cloud and manage real-world traffic efficiently.This course aims to provide you with the foundational knowledge required to build and understand backend systems, implement industry best practices, and create production-ready APIs that are secure, scalable, and maintainable. It is not just a step-by-step tutorial, but a comprehensive learning experience that prepares you for real-world scenarios.Legal Notice:All product and company names, logos, and trademarks featured on this thumbnail are the property of their respective owners.
