protoc-gen-js: program not found or is not executable

Trying to compile my protos - I need to compile them to use in my react app. But I get this error. I run the command as follows:

cd src/main/proto && protoc -I=. *.proto --js_out=import_style=commonjs:. --grpc-web_out=import_style=commonjs,mode=grpcwebtext:.

Where can I find protoc-gen-js? I didn't come across any repo for it.

There has been a lot of discussion on this error in the following issue:

Generate js file from proto file with protoc v21.1 #127

If any of you are open to using a different package for generating static code then you can use the following.

protobufjs-cli

Command line interface (CLI) for protobuf.js.

This can be used to translate between file formats and to generate static code as well as TypeScript definitions.

Installation:

npm i protobufjs-cli

Usage:

$> pbjs -t static-module -w commonjs -o compiled.js file1.proto file2.proto

I started using this package after I got the protoc-gen-js related error when using the protoc compiler for windows. I didn't find any solution mentioned in the issue linked above (as of June 2024) appealing, and I didn't want to install protoc-gen-js globally.

You should install this package globally or in the project devDependencies.

NPM

npm install -g protoc-gen-js
// or
npm install protoc-gen-js --save-dev

YARN

yarn global add protoc-gen-js
// or
yarn add protoc-gen-js --dev

For Mac users using brew and the provided link by Christopher Peisert what worked for me was the suggested workaround:

$brew install protobuf@3

$brew link --overwrite protobuf@3

As of July 2022, there is a known bug in protoc versions 21.1 and 21.2 (and libprotoc 3.21.1 and libprotoc 3.21.2).

See protobuf issue #10114.

For now, recommend downgrading to version 20.1 (libprotoc 3.20.1).
