Can you recommend open source projects with small codebase, but with high benefits for learning?

• tunl

  3 20 0.0 Go

  Instantly expose local services to the internet

Take a look at Tunl https://github.com/pjvds/tunl. It exposes local services and docker containers similar to Ngrok and might teach you a bit about reverse proxies, networking and creating a CLI tool.

• todocheck

• goja

  25 4,931 6.3 Go

  ECMAScript/JavaScript engine in pure Go

If you have some experience and find parsers and interpreters to be pleasant, take a look at https://github.com/dop251/goja because it's a pure Go (instead of calling out to v8 or quickjs via cgo) implementation of es5.1+ which is working it way towards es6+. I think it's a nice place to look if you have experience because the features needed are well defined with standardized tests, and you can work on one small thing at a time as a unit.

• booster

  27 452 6.3 Go

  Fast and secure initramfs generator

https://github.com/anatol/booster is an initramfs generator. Reading its sourcecode and contributing to the project will let you learn *a lot* about early boot process at Linux.

• luks.go

  3 75 1.6 Go

  Pure Golang library to manage LUKS partitions

https://github.com/anatol/luks.go a golang library to unlock LUKS partitions. Look at it if you are interested in cryptography.

• set

  5 46 3.2 Go

  Package set is a small wrapper around the official reflect package that facilitates loose type conversion and assignment into native Go types.

It's generally not well received to use reflect to step around Go's type system but there are also instances where the type system starts to violate DRY. I've put together a small package that uses reflect to work some magic on types @ https://github.com/nofeaturesonlybugs/set
