Learn Gin (high-performance HTTP web framework for Go) from the basics to production-grade: pre-requisites & environment setup, background history & why you need Gin, core concepts & main architecture, setup & hello world, routing & path parameters, request binding & validation, middleware, response rendering & static files, project structure & clean architecture, database & ORM integration, configuration & environment, error handling & logging, context timeout & concurrency, authentication & session authentication, RBAC OAuth2 & security middleware, HTTPS trusted proxies & input hardening, WebSocket streaming & SSE, testing & benchmark, observability & monitoring, performance & troubleshooting, latest stable features v1.11 & v1.12, production-ready architecture, and alternative ecosystem & final reflection — 23 episodes in total.
Before touching Gin, you need to master the basics of the Go language, the concepts of HTTP and REST, and the Go toolchain. In this episode you also set up the environment, install Gin v1.12.0, and verify your first installation.

This episode explores Gin's journey from its birth in 2014 to v1.12.0, the 40x performance motivation over Martini thanks to httprouter, the problems Gin solves, and its position compared to Echo, Fiber, chi, and plain net/http.

This episode dissects Gin's internal architecture: gin.Engine as the core of the framework, the radix tree router for matching paths and methods, the middleware chain that runs sequentially, and gin.Context, which carries the request and response.

This episode guides you step by step in building your first Gin project: module initialization, installing dependencies, understanding gin.New() vs gin.Default(), debug and release modes, creating your first routes, and running the server.

This episode covers Gin's routing patterns: path parameters with :id, wildcards with *filepath, query parameters, HTTP method matching, and RouterGroups for v1/v2 prefixes plus 404/405 handling.

This episode dissects Gin's request binding: JSON, query, form, URI, XML, YAML, and TOML; understanding the struct tags json, form, uri, and binding; the go-playground/validator/v10 library; and the differences between ShouldBind, MustBind, and Bind.

This episode dissects Gin middleware: writing your own middleware with c.Next() and c.Abort(), installing it with engine.Use(), using built-in middleware such as Logger, Recovery, BasicAuth, CORS, and gzip, and controlling the order of execution.

This episode dissects how to return responses in various formats: JSON, XML, YAML, TOML, and ProtoBuf. You'll also learn to render HTML templates, redirects, serve static files, handle file uploads, and stream responses.

This episode structures a Gin project with clean architecture: separating handlers, services, and repositories; using the internal folder; one package per domain; simple dependency injection; and separating the router setup so it's easy to test and scale.

This episode connects Gin to a database: choosing a driver, PostgreSQL connections with pgxpool and connection pooling, schema migrations with golang-migrate, and implementing the repository pattern and full CRUD with GORM.
