Golang does not use a framework

As an emerging programming language, Golang has become more and more popular among developers in recent years. Its birth has unique advantages in syntax design, performance and concurrent processing. At the same time, as Golang becomes more and more widely used in the industry, there are more and more Golang frameworks, such as Gin, Beego, Revel, etc., all of which have their own characteristics and advantages.

But, in the actual project development process, is it really necessary to use a framework? This article will discuss from Golang's language features and its application in actual development, in some cases, why we can or should not use the Golang framework to develop applications.

1. Efficient standard library

Golang’s standard library is very powerful and covers many fields, such as HTTP, database, encryption, etc. They are considered one of the best features of Golang. Many of the functions we need have been implemented in the standard library. We no longer need to reinvent the wheel, and the focus can be more on implementing business logic. In some cases, using the standard library can be simpler, more efficient, and more controllable than using a framework.

For example, if we want to write a simple HTTP server, we can completely use the net/http package in Golang's standard library.

The following is a simple example of using the standard library:

package main
 
import (
    "fmt"
    "net/http"
)
 
func indexHandler(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintf(w, "Hello World")
}
 
func main() {
    http.HandleFunc("/", indexHandler)
 
    if err := http.ListenAndServe(":8080", nil); err != nil {
        panic(err)
    }
}

In this example, we call the http.HandleFunc() method of the net/http package to define a URL route. The root directory "/" is mapped to the indexHandler() function. The http.ListenAndServe() function is used to start the HTTP server and listen to port 8080. This example is very simple, but enough to implement a basic HTTP server without using any framework.

2. More flexible control

When using a framework, we need to write applications in accordance with the provisions of the framework. This approach to development allows developers to start projects faster, as the framework provides many predefined features and templates that can be used to simplify and speed up the development process. However, this development method also has some disadvantages.

For example, if we need to build an application according to our own ideas or project needs, we may find that using a framework is more restrictive. If you want to use a different database, or some functionality is not predefined in the framework, you need to use the framework's extensions and middleware. When using the standard library, the code can be more flexible, and communication between applications, database and cache implementation, etc. can be easily realized.

If you have customized needs and you don’t need extremely high development speed, not using a framework can give you more flexible control over application development.

3. Deeper understanding

With a framework, you know what you need and what the framework provides. However, this approach makes it difficult to fully understand the inner workings of what we are using. In the process of using the framework, we may encounter many problems, such as performance problems, memory leaks, framework expansion problems, etc. In the process of solving these problems, understanding the internal mechanism of the framework can help us better understand and fix the problem.

If you don't use a framework, you can learn more deeply about Golang's language features, how the underlying APIs and functions are used, and the internal mechanisms. This way of learning not only improves your programming skills, but also gives you an in-depth understanding of how your application actually runs, making you more familiar with Golang's underlying mechanisms.

Conclusion

In most cases, the use of frameworks is to improve developer productivity and simplify the development process. But if you have unique needs or want to have a deeper understanding of Golang's underlying mechanisms, the framework-free approach may be a better choice.

In the actual project development process, we need to flexibly choose to use a framework or not use a framework based on the needs, complexity and developer experience of the project. Only in this way can applications be more efficient, controllable, stable, and meet different business needs.
