For the developers here: it's built with Vue 3, with the visualizations drawn on canvas using Konva. Each algorithm produces a list of steps up front, and the player just renders whichever step you're on โ which is what makes stepping back and scrubbing work. The pages are statically prerendered so they load quickly and are reasonably friendly to search engines. - Source: dev.to / 29 days ago

I have been assigned a task to create a sort of a canva clone which will have almost same features as canva with authentication, access control and rating system(not in this phase). I need help in finding libraries similar to https://konvajs.org/ which has updated docs and great support for Nextjs. Source: almost 3 years ago

I like the Databases section of CodeSignal Arcade. Problems increase in difficulty, plus I've found it's the platform a lot of companies use for SQL assessment so you'll get a good sense of the type of questions to expect. Source: over 4 years ago
Codesignal has a good set of SQL questions. Not sure they "support" Postgres, but there's 84 free levels under the Arcade section. https://app.codesignal.com/arcade. Source: over 4 years ago
