What's the state of the art for doing processing in in the browser?

e.g. I have a ~60km GPX file, ~100 points, and I wanna know the nearest distance of each point to the line.
I know exactly how to do this in postgis, or even by hand. I know basic JS. How can I do this in JS on a webpage? (pref. non nodejs)

@amapanda well if you know how to do it by hand you just need to convert it to JavaScript. You can use the console to write the functions and run them directly in the browser.

If that is too difficult, you could try writing your own script.

Basically you will need to do `document.getElementById()` or class or tag name and bind everything to those items. No nodejs or backend needed.

@barefootstache I like to check if there's a library to do all this, before i spend time writing all the code myself. 😉
