abyss-tracker VS uPlot

The Abyss Tracker - great place to find fits and see average loot for different types of abyssals, amongst other things

Abyss Tracker - Great for finding fits and estimating loot rewards, amongst other things E-Uni page - Covers the basic mechanics and rules YouTube - Many great guides from AceFace and others, just avoid anything more than a year and a half (or so) old, since Abyssals have changed since then so old fits won't work. "Abyssal Lurkers" ingame chat channel (and associated discord) - Great for asking questions and chatting with other abyssal runners.

My personal impementation for https://abyss.eve-nt.uk/ (this is not well written code but it is working)

Abyss Tracker - you can find all kinds of fits here.

try to find fittings by asking in the Abyssal Lurkers chat channel and https://abyss.eve-nt.uk

And this site is super useful both to see fits and to track your own runs and performance https://abyss.eve-nt.uk/

Can you fly a Vagabond? It can do abyssals. I can't advise you on max tier but start low anyways. For fits you can check zkill or https://abyss.eve-nt.uk/

So whats up with https://abyss.eve-nt.uk/ ?

Here is a very efficient 2D canvas lib that is extremely efficient https://github.com/leeoniya/uPlot i recommend looking through their readme and seeing if it solves your current problems.

BACKEND:

It's about 3000 lines of Crystal code https://crystal-lang.org/ -- it's been an absolute dream to program in. Ruby-like syntax, statically compiled performance. Nice standard library. Would recommend :)

Performance == caching

Local ephemeral filesystem for shortest-term caching.

Redis for shared medium-term caching and locking.

S3-compatible object storage for longest-term caching (for raw data feeds pulled every evening by a cronjob).

FRONTEND:

Bootstrap

uPlot https://github.com/leeoniya/uPlot

Just a sprinkle of inline JS+CSS on the page.

you can use matchMedia to detect devicePixelRatio changes and re-sync:

everything stays crisp even as you browser-zoom. e.g. https://leeoniya.github.io/uPlot/demos/area-fill.html

Safari's slow release cadence (typically tied to OS version upgrades) does leave it more broken and for longer than Firefox, Chrome, Opera and other browsers that are updated more frequently and not tied to the OS.

just recently i ran into incompatibilities with Safari < 14 needing the old-spec matchmedia api:

uPlot will handle this. https://github.com/leeoniya/uPlot

If you are showing 100s of thousands of points, I'd still go with canvas eg uPlot. It's a really, really excellent library.

The existing node red chart tools is not great. I'd like to be able to use uplot instead. The uplot-charts node should work very much like that charts node built into node-red-dashboard.

super cool!

i've done my share of optimizations and benchmarking charting libs [1] but this goes deeper still.

SVG is not a good choice for large raw datasets when you need performance.
