7 Useful Go Libraries You Should Use in Your Next Project
There is a proverb “You don’t have to reinvent the wheel”. Libraries are the best example of that. It helps you to write complex and time-consuming functionality in an easy way. According to me, a good project uses some of the best libraries available.
I do not think Go (Golang) needs any introduction. It is developed by Google and designed to be a simple, efficient, and reliable language for systems programming and network programming. Here I have compiled 7 useful GO libraries that will help you in your development journey.
1. Cobra
If you want to create a powerful modern CLI application then this is one of the best resources you can have. It is also one of the most starred libraries with more than 30k stars on GitHub. It includes lots of features like nested subcommands, automatic help generation for commands and flags, easy subcommand-based CLIs: app server, app fetch, etc, and many more.
2. Bigcache
Caching is one of the best ways to improve app performance. This library provides a fast, concurrent, evicting in-memory cache written to keep a big number of entries without impact on performance. It keeps entries on the heap but omits GC for them. To achieve that, operations on byte slices take place, therefore entries (de)serialization in front of the cache will be needed in most use cases. It has more than 6k stars on GitHub.
3. Asciigraph
This library will help you to generate beautiful, ASCII-based graphs. It can be used to create a variety of different types of graphs, including line graphs, bar graphs, and scatter plots, and it is highly customizable, allowing developers to control things like color, axis labels, and grid lines. It has more than 2k stars on GitHub.
4. Env
Every project has a .env file. This library will help you to handle environment variables. It includes support for type casting and struct tagging, making it easy to automatically bind environment variables to struct fields. It also provides a simple and easy-to-use API for reading and parsing environment variables, as well as for setting default values. This library has more than 3k stars on GitHub.
5. Authboss
Authentication is one of the common features every app has. This library provides a modular authentication system for the web. It has several modules that represent authentication and authorization features that are common to websites in general so that you can enable as many as you need, and leave the others out. It makes it easy to plug in authentication to an application and get a lot of functionality for (hopefully) a smaller amount of integration effort. It has more than 3k stars on GitHub.
6. Oto
If you have to work with audio then this is a good resource for you. It is a simple and lightweight library that provides a clean and easy-to-use interface for playing audio files. It supports various audio formats including WAV, MP3, and OGG, and is designed to be fast and efficient, making it ideal for use in games, music players, and other applications that require real-time audio playback. It has more than 1k stars on GitHub.
7. Roaring
Roaring bitmaps are compressed bitmaps and they can be hundreds of times faster. This library provides Roaring bitmaps in Go. It includes a wide range of functionality for working with Roaring Bitmaps, including support for set operations like union, intersection, and difference, as well as for iterating over the elements of a bitmap. This library has more than 1.5k stars on GitHub.
