bigint: Failed to load bindings

[Juici]

Problem

Currently import of @solana/web3.js will result in a console.warn of:
bigint: Failed to load bindings, pure JS will be used (try npm run rebuild?)

This is due to rollup bundling the bigint-buffer package from the @solana/buffer-layout-utils dependency. bigint-buffer has a native module which it attempts to import:

if (!process.browser) {
  try {
    converter = require('bindings')('bigint_buffer');
  } catch (e) {
    console.warn(
        'bigint: Failed to load bindings, pure JS will be used (try npm run rebuild?)');
  }
}

The problem is that the above code relies on the native module existing in the correct location in the package it is run in. Since rollup bundles the require into @solana/web3.js the native module will never exist and will always result in the warning.

Proposed Solution

bigint-buffer can be added to the list of dependencies prevented from bundling in rollup.config.js.

Thanks for the report! So, I suppose that the error being caught in the catch block was ‘Could not load the bindings file…’ right?
