languages VS redis-tester

We don't currently have Swift yet (not a highly requested language yet) but I just wanted to highlight that our language support mechanism is actually OSS.

https://github.com/codecrafters-io/languages

Also, I wouldn't actually say we're the best resource to learn to use Redis (the Redis docs are probably more ideal) — we focus on helping you create your own version of Redis from scratch, so that you understand the fundamental pieces behind building a project like Redis. Same for Docker, Git, etc.

We do have a lot of users that actually discover Redis on our site, and do the learning Redis + building it out in parallel, often times while also simultaneously learning a new language!

Love your spirit.

Most key pieces of https://codecrafters.io are OSS.

We've found that users who want to learn a new programming language, and don't see it listed contribute language support before they attempt the course.

That was pretty mind blowing to me.

e.g Our Build your own Docker course got Rust support from a community contribution, https://github.com/codecrafters-io/languages/pull/93 — and it's among our most popular combination till-date!

I'd also recommend https://codecrafters.io/ - I did the Redis challenge recently while trying to (re)learn Java and it was a good experience.

I'm a former Engineering Manager, now working on Codecrafters, a site for programming challenges based on the Build your own X format.

For those of you who're interested, I've been working on converting these into hands-on coding challenges: codecrafters.io.

PS. If you're really interested, the repository that powers language support is open source, so you can contribute support for any language you'd like. Most of the recently added languages were contributed by early access users. Here's an example PR.

Thanks for the great question. We support ~14 languages at the moment and are working on adding more. You can visit our tracks page (https://app.codecrafters.io/tracks) to see the courses available against each language.

As a 2-person team, we're prioritising making a complete experience for Go, Python & JS for starters (our most popular languages).

So far, our tests are language agnostic. Our testers are written in Go (they’re open source, example: https://github.com/codecrafters-io/redis-tester). The testers interact with user code by testing for observable behaviour - exit codes, stdout/stderr, files written etc.

Although the testers are language-agnostic, a lot of the educational “content” is language-specific. We emit language-specific hints in stages where appropriate, and have expert solutions that are language-specific. A lot of this is new, so we might not have coverage across all challenges - this will improve over time.

Does that help explain our setup a little better?
