The most common Golang Development mistakes

Golang is a powerful programming language that is perfect for web development. It is fast, reliable, and easy to use. Golang is also an open source language, which means that it is constantly being improved by the community. It is a statically typed, compiled programming language created at Google. It is not uncommon for developers to make mistakes when working with a new language.

Here is a list of the most common mistakes made when developing with Golang:

1. Forgetting to handle errors

One of the most common mistakes made when developing with Golang is forgetting to handle errors. golang-faq points out that “Go programs compile and run without noise by default”. This can be misleading for developers who are used to languages that throw exceptions by default.

It is important to remember that in Golang, it is up to the programmer to handle errors. Failure to do so can result in unexpected behaviour and/or program crash.

2. Trying to use nil as a zero value

Another common mistake is trying to use nil as a zero value. In Golang, nil has a special meaning and cannot be used as a zero value for types. Attempting to do so will result in a compiler error.

3. Incorrectly using the blank identifier

The blank identifier is a special identifier in Golang that can be used in place of a named identifier. It is often used when a programmer does not need to use the name of an identifier, such as when assigning values to a struct field.

However, the blank identifier should not be used indiscriminately. Using the blank identifier in place of a named identifier can lead to code that is difficult to read and understand.

4. Not using go fmt

One of the benefits of developing with Golang is that the go fmt tool can be used to automatically format code. go fmt is a go tool that takes care of formatting code according to the Go standard.

However, many developers make the mistake of not using go fmt, which can lead to code that is difficult to read and understand.

5. Declaring unnecessary variables

Golang is a statically typed language, which means that variables must be declared before they can be used. This can lead to developers declaring unnecessary variables, which can clutter code and make it more difficult to read.

6. Not using named return values

In Golang, named return values can be used to improve the readability of code. By explicitly naming the return values of a function, it can make the code easier to understand.

However, many developers make the mistake of not using named return values, which can lead to code that is more difficult to read.

7. Misusing defer

Defer is a keyword in Golang that can be used to postpone the execution of a function until the surrounding function returns. Defer is often used to close files or release resources.

However, defer can be misused, which can lead to code that is difficult to read and understand.

8. Not using the right data type

Golang has a number of built-in data types, such as string, int, and bool. It is important to use the right data type for the job, as using the wrong data type can lead to unexpected behaviour.

9. Not using the built-in libraries

Golang has a number of built-in libraries that can be used to develop applications. These libraries can save developers a lot of time and effort.

However, many developers make the mistake of not using these libraries, which can lead to code that is more difficult to write and maintain.

10. Not using golangci-lint

golangci-lint is a tool that can be used to lint Go code. Linting is the process of checking code for errors, such as style errors, potential bugs, and unused code.

golangci-lint can save developers a lot of time and effort by identifying errors in code that would otherwise be difficult to find.

However, many developers make the mistake of not using golangci-lint, which can lead to code that is more difficult to read and understand.

Final Words

Each of these mistakes can be easily avoided with a little bit of knowledge and care. By using interfaces, you can ensure that your code is more maintainable and easy to understand. Inconsistent variable names can be confusing and make your code harder to read, so be sure to choose names that are clear and easy to follow. Pointers are a powerful tool, but they can be dangerous if used incorrectly. Be sure to understand how they work before using them in your code. Finally, don’t ignore errors! Always handle them in a way that is graceful and maintainable.
