Support Web-only use case

[kebugcheckex]

I'm building a tool similar to AST Explorer. It doesn't have a backend and everything runs in the browser. However, there are code in debugger.ts and index.ts referencing Node.js libraries. This causes errors in the browser environment as these libraries cannot be found. Those code are used to read Thrift code from files.

Is there a workaround? Right now I just comment out those code my usage doesn't need them. But is there a better way I can solve this issue?
