Error: Cannot find module 'buffer/'

The characters / is redundant ?

This is an issue with node polyfills on some environments. We currently have a ticket to bundle both @sei-js/core and @sei-js/react with webpack + babel instead of just babel to resolve these dependencies and will add an FAQ section to our docs. Is this a frontend or backend project you are working on? I'm happy to help resolve this issue for you. Typically you need to polyfill your app in this case.

I use it in typescript scripts with ESM.

run as:

npm run test

logs:

> ts-node-esm ./index.ts
