How Should I Name My Go Library Package to Avoid Conflicts and Improve Organization?

Go Library Package Name Best Practices

Intro
Package naming is crucial for the organization and accessibility of external Go libraries. Here are some common questions and best practices to consider when choosing package names.

Use Generic Names Sparingly
While using generic names like "text" may seem intuitive, it's generally advisable to avoid them. As you cannot create nested packages in Go, using a generic name for a library that processes text may lead to conflicts with other packages or functions using the same name. It's recommended to use more specific names that reflect the library's purpose, such as "textprocessing."

Package Collisions and Publishing
To avoid package collisions, ensure that your library has a unique name that distinguishes it from others. Use the "import path" feature to achieve this. This path should include the location of your source code, such as:

$GOPATH/src/github.com/[your_username]/[library_name]

Combining Libraries Under One Package
Combining different libraries under one package is possible in Go. However, it's essential to consider if it aligns with the purpose of your libraries. If the libraries have distinct functionalities, it may be more suitable to keep them separate to avoid potential package pollution issues.

Additional Tips

• Avoid Local Renaming: Select distinct names to prevent the need for local renaming in client code.
• Consider Domain Names: Dave Cheney suggests controlling namespace by prefixing packages with your company name or domain, reducing collision risk.
• Reference Package Names: When importing external libraries, use their full name to avoid naming conflicts. You can introduce aliases for shorter referencing.
