Can not build web3.js using esbuild

[nonken]

I have a simple client.js

import { Connection, SystemProgram, clusterApiUrl } from '@solana/web3.js';

And create a bundle using

esbuild ./client.js --bundle --outfile=./build/js/client.js

When including the bundled file on a simple page I am getting a bunch of bundling issues and can not use the output bundle.

Uncaught TypeError: require_elliptic2(...) is not a function

The issue is likely coming from https://github.com/cryptocoinjs/secp256k1-node/blob/master/elliptic.js

Fix:

When using elliptic directly instead of secp256k1, the bundle works:

solana-web3.js/src/secp256k1-program.ts

Line 3 in 171c73e

import secp256k1 from 'secp256k1';

I don't know if this is a possible fix though or if secp256k1 is needed for node envs?

Maybe is better to get full support esbuild bundlers like Vite/Snowpack #1036 out of the box ?
