The generated commonjs `*_pb.js` files don't work in Node.js environment

[yevhenii-nadtochii]

This bug is a rebirth of protocolbuffers/protobuf#9152, which has already been fixed in v3.19.1. It seems the fix hasn't been delivered to the latest version.

What version of protobuf and what language are you using?
Version: v3.20.1
Language: Javascript

What operating system (Linux, Windows, ...) and version?
macOs Monterey v12.3.1

What runtime / compiler are you using (e.g., python version or gcc version)
Node.js v16.13.0

What did you do?

1. Run protoc --js_out=import_style=commonjs,binary:path/to/out/dir --proto_path=. *.proto
2. Try to import and use the generated *_pb.js files.

What did you expect to see
Import and use without errors (just as in 3.19.1 - 3.19.4).

What did you see instead?

ReferenceError: window is not defined

   14 | var jspb = require('google-protobuf');
   15 | var goog = jspb;
 > 16 | var global = (function() { return this || window || global || self || Function('return this')(); }).call(null);

FYI, this was fixed in 3.19.x by PR #9156 in the old repo, but regressed to the old behavior. I've verified that this works with protoc version 3.19.4, but fails with 3.20.1.

Any progress on this issue, running into the same problems. I'am not be able to compile an old version of libprotoc on apple silicon m2 arm64. brew install --build-from-source protobuf-3.19.4 -> Error: protobuf-3.19.4 did not build

Error using *_pb.js
var global = (function() { return this || window || global || self || Function('return this')(); }).call(null);

Thanks

3.19.4 predates the split off of protobuf-javascript from the main protobuf repo. Do you still have a problem with protobuf v21+ (there was a numbering scheme change ~3.21) and the current published google-protobuf npm package/3.21 of protobuf-javascript? The main difference is you need to start specifying a --plugin flag to protoc to point it to protoc-gen-js.

libprotoc 3.21.5

cd lib/server && protoc \
		--plugin=protoc-gen-ts=./node_modules/.bin/protoc-gen-ts \
		--plugin=protoc-gen-grpc=./node_modules/.bin/grpc_tools_node_protoc_plugin \
		--js_out=import_style=commonjs,binary:./src/proto \
		--ts_out=service=grpc-node,mode=grpc-js:./src/proto \
		--grpc_out=grpc_js:./src/proto \
		-I ../../protos ../../protos/xxx.proto
protoc-gen-js: program not found or is not executable
Please specify a program using absolute path or make sure the program is available in your PATH system variable
--js_out: protoc-gen-js: Plugin failed with status code 1.
make: *** [gen-server] Error 1

Error mentioned in #127
--plugin flag already in use as you recommended

libprotoc 3.20.1
var global = (function() { return this || window || global || self || Function('return this')(); }).call(null);

Any other ideas i could get the last working version of libprotoc 3.19.4 running on arm64?

[dibenede]

The surface level issue appears to be that it can't find protoc-gen-js on your PATH. However, I'm not familiar with either protoc-gen-ts or protoc-gen-grpc, so you may have better luck asking one of those projects how they depend on protoc-gen-js.

We are forced to use 3.20.3 (where this bug is still present) because of #127,
but were able to workaround this via

// @ts-ignore
globalThis.window = null;
// @ts-ignore
globalThis.self = null;

at the start of our index.ts.

I'm seeing this same issue - can we re-open this issue?

[dibenede]

@tbarlow12 Can you please describe your setup and any reproduction instructions?
