protobuf.js version: <6.6.3>

Thanks for your library!
Unfortunately I found out that es6 modules are compiled into TypeScript typings incorrectly.
I have multiple export statements in the ts file while js file has single default export.

Let's say I have following .proto:

syntax = "proto3";

message ExceptionModelItem {
    string text = 1;
    double value = 2;

    enum ExceptionStatus {
        ERROR = 0;
        WARNING = 1;
        OK = 2;

    ExceptionStatus  status = 3;

message ExceptionModelItemList {
    repeated ExceptionModelItem items = 1;

message ExceptionModel {
    repeated ExceptionModelItemList items = 1;

And I have following generation code:

#!/usr/bin/env bash

for item in $( ls *.proto); do
    echo $FILENAME
    ARRAY+=("export * from './"$FILENAME"';")
    pbjs -t static-module -w es6 -o ../typescript/src/$FILENAME.js $item
    pbts ../typescript/src/$FILENAME.js > ../typescript/src/$FILENAME.d.ts

printf "%s\n" "${ARRAY[@]}" > ../typescript/src/index.ts

When I try to use the code above, es6 modules doesn't work. But if you try to use common js, the result works just perfect.

Hmm, does it work with the -n option (wraps everything in a module)?

pbts -n $FILENAME ../typescript/src/$FILENAME.js > ../typescript/src/$FILENAME.d.ts

The general issue could be that es6 modules export everything as default, where export * from might not work.

I think export is the issue. But I don't get how to use the TS compiler with the es6 modules.
-n option did not solve the problem.
