Typescript Type generation not working using proto-loader-gen-types

[anurag-dhamala]

Problem description

I can not generate typescript types.

Dependencies

"@grpc/grpc-js": "^1.14.4",
"@grpc/proto-loader": "^0.8.1",

Proto files are located in the project root directory inside proto in the following structure:

proto/common/v1/common.proto
proto/user/v1/user.proto
proto/tag/v1/tag.proto

When I run the command by providing individual proto file through make command:

❯ @npx proto-loader-gen-types --longs=String --enums=String--defaults --oneofs --grpcLib=@grpc/grpc-js -I=./proto/ -O=src/lib/server/grpc/types/ user/v1/user.proto

It works and generates the necessary types in the desired directory.

However when I run this:

❯ @npx proto-loader-gen-types --longs=String --enums=String--defaults --oneofs --grpcLib=@grpc/grpc-js -I=./proto/ -O=src/lib/server/grpc/types/ **/**/*.proto

It does not work.

It does not work with */*/*.proto , *.proto , */*.proto .

I get the error when I try with various approaches of using *:

(node:9591) Warning: */*.proto not found in any of the include paths proto/
(Use `node --trace-warnings ...` to show where the warning was created)
[Error: ENOENT: no such file or directory, open '*/*.proto'] {
  errno: -2,
  code: 'ENOENT',
  syscall: 'open',
  path: '*/*.proto'
}
make: *** [testss] Error 1

I also ran :

	@npx proto-loader-gen-types --longs=String --enums=String--defaults --oneofs --grpcLib=@grpc/grpc-js -I=./proto/ -O=src/lib/server/grpc/types/ user/v1/*.proto

It doesn't work either. When I remove * and give the actual filename, it works however.

My assumption is that * is not being expanded at all.

Environment

OS name, version and architecture: MacOS Tahoe 26.6.2
Node version: v24.12.0
Npx Version: v11.6.2

Glob expansion is in fact not currently supported in the generator. I can treat this as a feature request to add that support.
