Performance

[samuelmf1]

Hi there,

I am wondering if anyone has input about the performance of locuszoom.js? What kind of lag might I anticipate if building it into a React app?

TIA

Generally we've found performance to be pretty snappy, as long as you are careful to avoid excessive re-renders. (a common pitfall in any web framework, where changes may happen automatically)

Here's a live version of LZ.js rendered using vue.js as a baseline:
https://my.locuszoom.org/gwas/236887/region/?chrom=16&start=53609247&end=54009247

Under the hood, LZ tries to handle really dense regions by combining adjacent points, which means that even bigger datasets shouldn't overwhelm the renderer in most cases.
