Hands-On Dependency Injection in Go

Code bloat

Code bloat smells are cases where unwieldy slabs of code have been added to structs or functions so that they have become hard to understand, maintain, and test. Frequently found in older code, they are often the result of a gradual degradation and lack of maintenance rather than intentional choices.

They can be found with a visual scan of the source code or by employing a cyclomatic complexity checker (a software metric that indicates the complexity of a piece of code) such as gocyclo (https://github.com/fzipp/gocyclo).

These smells include the following:

• Long methods: While the code is run on computers, it is written for humans. Any method of more than about 30 lines should be split into smaller chunks. While it makes no difference ...
