Ask HN: Best open-source projects to learn from?

[shubh2336]

What are the best open-source projects / snippets of code that caught your attention? I understand that there are different criteria when someone classify something as best / beautiful. I mean below properties when I mention the word 'best' -

a) Solves a real problem b) Relatively easier to understand c) Relatively easier to modify / extend d) Relatively easier to test e) Has seen an evolutionary curve over time

I make my living by writing code for past few years & feel like reaching out to the best folks in the industry for their insights.

I'm a team member of an open-source React framework for building CRUD apps.We are trying to use industry-standard best practices. So I suggest you inspect the project and understand what's going on.

It's written in TypeScript and rely heavily on hooks architecture GitHub Repo: https://github.com/refinedev/refine

It very much depends on the type of project, the programming language(s), scope and scale.

I tend to focus on things that I'm passionate about and look for reputable and popular open source projects in that area, ie VLC, Audacity, GIMP etc.

This website has several great projects so worth taking a look to see if something catches your eye: https://www.codetriage.com/

For mapping, I really enjoyed working with Openlayers.
