In what cases is it recommended to use the REST architectural style for API development?

The REST architectural style is recommended for API development in the following cases:

• When you need to create a distributed system with a client-server architecture, where clients and servers evolve independently.
• If scalability and caching are required, as REST uses standard HTTP methods and status codes.
• To ensure simplicity and universality of interaction through standard protocols (HTTP).
• When support for various data formats (JSON, XML, etc.) and broad compatibility are important.

REST is suitable for public APIs, mobile applications, web services, where ease of integration and standardization are important. In Go, REST APIs can be easily implemented using the standard net/http package and routers.

Example of a simple REST handler in Go:

http.HandleFunc("/users", func(w http.ResponseWriter, r *http.Request) {
    if r.Method == http.MethodGet {
        // return list of users
    } else if r.Method == http.MethodPost {
        // create a new user
    }
})
