Add plugin option to add .js at end of imports

[Levyks]

Currently, protobuf-ts create files with imports like this:

// @generated by protobuf-ts 2.9.4
// @generated from protobuf file "connection_handler.proto" (package "myapp.connection_handler", syntax proto3)
// tslint:disable
import { Empty } from "./common";

However, when using type: "module" and depending on your tsconfig, you're forced to put the .js extension for it to work, would it be possible to add an option to the plugin to generate it like this?

// @generated by protobuf-ts 2.9.4
// @generated from protobuf file "connection_handler.proto" (package "myapp.connection_handler", syntax proto3)
// tslint:disable
import { Empty } from "./common.js";

In the meanwhile, if anyone is facing the same issue, I was able to get around it by installing replace-in-files-cli and doing this in my compile script:

{
  "scripts": {
    "compile:protos": "protoc --ts_out ./your_out_dir --proto_path ../proto ../proto/*.proto && replace-in-files --regex='import (.*?) from \"\\.\\/(.*?)\";' --replacement='import $1 from \"./$2.js\";' './your_out_dir/*.ts'"
  }
}
