What should I do if golang is too big?

As cloud computing platforms become more mature and containerization technology becomes more popular, application volume requirements become more and more stringent. Some small programming languages ​​and frameworks have emerged, such as Go language (Golang), which is a It is a language dedicated to simplifying the programming process and improving program running efficiency. However, with the continuous expansion of application scenarios, Golang's size problem has attracted more and more attention.

1. The reason why Golang is large

Golang needs to rely on many library files during the compilation process, so when building an executable binary file, these library files will be embedded into the binary file, thus This causes the size of Golang binary files to increase. In addition, features such as Golang's garbage collection mechanism and coroutine mechanism will also make binary files larger.

2. Methods to solve the large size of Golang

1. Use Golang's compilation flag -fpic or -shared. These compilation flags embed the dynamic link library into the executable file, which can be effective Reduce executable file size.
2. Divide the Golang program into various modules, and each module can be compiled separately and generated into a dynamic link library. These modules are then connected using dynamic linking to ultimately generate an executable binary file. This method can effectively reduce the size of the executable file.
3. Use file compression tools such as UPX to compress the executable file to reduce the size of the executable file.
4. It is recommended to use Golang’s official build tool Go build, which will automatically remove unused library files. At the same time, you can also reduce the size of the program by reducing the number of lines of code in the program and deleting some unnecessary code.

3. The size problem of Golang in application

For some simple command line tools, the size problem of Golang will not have much impact, but for some specific scenarios , such as mobile applications, even a small application needs to consider the issue of application size. In this case, Golang may not be the most suitable choice. You should consider choosing some smaller programming languages ​​or frameworks, such as Rust, C language, etc., to develop corresponding applications.

Of course, Golang’s size problem in applications does not negate its application value in cloud computing, enterprise-level backend and other fields. In these fields, the size of the application will not be a consideration in most cases, but Golang can provide developers with efficient and safe development tools to help them solve complex business problems.

To sum up, Golang’s large size is not inevitable. Developers can reduce the size of the program by using appropriate compilation flags, dynamic link libraries and other technical means. However, for specific application scenarios, it is necessary to choose an appropriate programming language or framework based on the actual situation to achieve the best volume effect.
