I am trying to compile a very simple typescript code with esbuild.

However esbuild is compiling only the entry file.

This is my setup:

//index.ts
import * as mod1 from './mod1';
mod1.my_method();

//mod1.ts
export function my_method(){
  console.log('debug');
}

I run:

esbuild index.ts --outdir=./dist --platform=node

the compilation is done with no error and if I now check the dist I get only

dist
- index.js

// dist/indes.js
import * as mod1 from './mod1';
mod1.my_method();

but there is no trace of dist/mod1.js. So of course the code cannot run and give an error.

Why esbuild is not compiling all the other files like mod1.ts?

I can't use --bundle in my project.
