The Go stdlib library is powerful, but for real-world products, a lot of additional requirements in terms of middleware, routing, persistence, and so on crop up. It is advisable to use a suitable web framework as guiding rails for your API project. One popular framework is Gin. Some of its features are the following:

• Radix tree-based Go (Golang) routing
• Small memory footprint and predictable performance due to controlled engineering (in terms of memory allocations)
• Middleware framework where various middleware can be chained before the final handler
• Panic recovery during request handling
• Route grouping, with various middleware on different URL route hierarchies
• JSON validation
• Error management
