This package doesn't work with NestJS

[8naf]

Bug description

I am using this package to compile my NestJS project. The compilation process is successful, but when running the application, it throws an error.
I'm not sure if this issue is caused by NestJS or tsx, so I tried compiling my project with ts-node and tsc, and everything worked fine. That's why I decided to create the issue here.

Reproduction

This is the reproduction.

Run the start:tsx script and access localhost:3000, the terminal will log an error: Cannot read properties of undefined (reading 'get').
You can run the start:ts-node or start:tsc script and access localhost:3000 to see that the application does not have any errors.

Environment

System:
    OS: Windows 10 10.0.19045
    CPU: (4) x64 Intel(R) Core(TM) i7-7600U CPU @ 2.80GHz

Can you work on a fix?

I haven't looked into it extensively, but it looks like your code is using decorators.

esbuild doesn't support decorators:

• https://github.com/esbuild-kit/tsx#does-it-have-any-limitations
• https://esbuild.github.io/content-types/#no-type-system

Sorry for not reading the readme file carefully.

This package is really great as it supports TS + ESM + tsconfigs paths altogether. It's a pity that it's facing this limitation. Maybe I'll look for another solution.

I will close this issue for now and reopen it when esbuild supports decorators.
