@solana/web3.js is not tree-shakeable.

In src/index.ts I'm only importing a numeric const (LAMPORTS_PER_SOL)

import { LAMPORTS_PER_SOL } from "@solana/web3.js";
console.log(LAMPORTS_PER_SOL);

the expected compiled file would look something like this

const LAMPORTS_PER_SOL = 1000000000;
console.log(LAMPORTS_PER_SOL);

but currently the entire web3.js package is injected, which means the output filesize is about 1000x larger than this and includes many extra libraries (that can have issues with react native etc) that aren't necessary.

Builds

Outputs for ncc, rollup and webpack are in the dist/ directory.

tool	command	minified filesize
ncc	npm run build:ncc	512 kB
rollup	npm run build:rollup	483 kB
webpack	npm run build:webpack	381 kB

Notes

I tried building @solana/web3.js with typescript's tsc instead of rollup but https://github.com/Rich-Harris/agadoo still claims its not tree-shakeable.
