The other big option is to post blogs or notes. It's pretty simple to start a blog right here on Dev.to, or on Hashnode, two blogging platforms specifically for coding. There's also a great community platform on Codedex.io where you can write blog posts, although you do need to complete a few lessons to "unlock" the community features. In these cases, there's already an audience and community on the site, so it's easier for your posts to get seen. If you want a more personalized blog, or want to blog about learning other stuff besides coding, you can try Substack. If you wanna get fancy, you can even self-host the similar blogging platform Ghost, like I do for my art blog! (Self-hosting is a great learning experience in and of itself!) IMO, these options are best when you want to write more focused and thought-out pieces like tutorials and guides, or even just "here's everything I know about CSS selectors" or whatever. Basically, I turn to these blogging platforms when I'm writing directly for the sake of informing other people.

Project mention: A Step By Step Guide to Updating Your Legacy Node.js App in 2024 (v10 to v22) | dev.to | 2024-07-25
Crawly is an Express app built on the bones of hackathon-starter, a boilerplate package for Node apps. Surprisingly, this project is still alive and well maintained in 2024. But there's no guarantee that the project still uses the same dependencies (it doesn't), and there's a likelihood that even more dependencies would be added (there were). So I abandoned any plans to merge the latest in.
