salojooon Konva.js - Declarative 2D Canvas for React, Vue, and Svelte

The amount of concurrent webgl canvases on a page is limited by browsers. I believe it's somewhere between 8-20 depending on the browser.

Hopefully webgpu would lift that limit?

I'm rendering charts. The native API conveniently provides the fundamentals with lines and rectangles. In addition masking and text have been very useful.

Interaction is also supported by the API with hit regions, though I've opted to do my calculations. But I agree that interaction is where Konva would probably have shined.

I evaluated this vs pixi and native canvas API. In the end I decided to use native API.

Konva didn't have enough performance for my use case and pixi webgl has a limit on the number of canvases on the screen at the same time

The native API is easy to use and well documented. It also performs well enough to animate charts at 60fps on modern hw for my use case. I also like that there are no libraries to update

salojooon The notifier pattern for applications that use Postgres

Right, I didn't know it was possible to bypass full channels like that with select/default. Thanks for spelling it out

salojooon The notifier pattern for applications that use Postgres

We probably both understand the underlying concepts correctly. But just in case: also buffered channels will block if full.

So I don't see how notifications get discarded (meaning lost). But somehow that's what your text says?

salojooon The notifier pattern for applications that use Postgres

"Instead, a received notification is immediately sent into buffered channel, which means it’s discarded if the channel is full"

Shouldn't the channel rather block than discard if full?

Anyway, nice and relevant article for me as I've recently added a few listeners to my app. I chose the naive approach since I only have two topics and a surplus of connections

salojooon Snapdragon X Elite Multi-Core Superiority Claims over Apple's M3 Were Right

Performance per dollar has traditionally been the selling point with PCs. Performance per watt is the selling point with Apple silicon.

Does this one fit somewhere in between?
