Kiwi News bundle.js. It's sadly 2MB big and I'd like to reduce its size. But I don't see any obvious optimizations.

Can you migrate from Ethers to Viem?

I‘m open to it but what are the consequences and what do I gain?

Outside of the time to migrate, would check to see if there's any gaps in coverage for how you currently use Ethers (migration guide: https://viem.sh/docs/ethers-migration.html) but you'd likely see some benefits from a bundle size & performance standpoint: https://viem.sh/docs/introduction.html#bundle-size

I feel a bit sad for @ricmoo also: Why migrate from ethers, it's a good lib no?

Ya I mean ethers is great, but we made that change b/c of the performance/bundle improvements offered. I mean, to your original question about ways to lower your bundle size, this is seemingly an opportunity, but also totes agree that there's costs involved with making that change

I’m also curious how much the bundle size changed? Ethers aggressively supports tree-shaking (using file boundaries, which works even with older, less advanced bundlers too ;)). So it shouldn’t have included things you didn’t need…

Hrm so will take a bit of time to recreate the same conditions to compare and contrast will try to follow up here

That sounds like a lot of work for a data point. I was just curious if you knew it off-hand. :)

No worries! Just checked some logs and there was around a 67 kB reduction in the First Load JS directly following the change. This was done in conjunction with upgrading Wagmi and Rainbow though, so it may not be a 1-to-1 comparison.
