ReferenceError: Buffer is not defined

I have this issue on web, my build system is based on TypeScript 2.9.2, relevant lines from tsconfig:

{
  "compilerOptions": {
    "moduleResolution": "node",
    "target": "es5",
    "lib": ["es2017", "dom"],
    "allowSyntheticDefaultImports": true,
    "esModuleInterop": true
  }
}

For now I can work around it by setting Buffer on window.

import { Buffer } from 'buffer';
window.Buffer = Buffer;

I have the same problem "typescript": "~3.7.5"

Same problem, I ended up using your workaround and now everything works. It's because this library calls one of the functions from the original NodeJs library (which expects the Buffer type)

Same problem for me, but I think the solution cannot replace all new Buffer(...) in tool.ts of the library. Any update on this ?
