Protogen

Protogen is a Node.js application that generates .proto files based on the descriptors provided by a gRPC reflection service. The generated .proto files can be exported as a .tar.gz archive for easy transport.

Features

• Interactively query a gRPC reflection service to generate .proto files.
• Handles methods that are not implemented and reports missing methods.
• Exports generated .proto files into a .tar.gz archive.

Prerequisites

• Node.js (v14.x or later)
• Yarn package manager

Installation

1. Clone the repository:

git clone https://github.com/yourusername/protogen.git
cd protogen

2. Install the dependencies:

yarn install

Usage

1. Run the script:

node generateProtos.js

2. Follow the prompts:
   • Enter the gRPC endpoint.
   • Select the connection type (plaintext or TLS).
   • Choose whether to generate a .tar.gz file for the .proto files.

Example

? Enter the gRPC endpoint: sei.grpc.kjnodes.com:443
? Select connection type: TLS
? Do you want to generate a .tar.gz file for the .proto files? (Y/n) Y

Output

• The generated .proto files will be saved in the generated_protos directory.
• If opted, a .tar.gz archive of the generated_protos directory will be created as generated_protos.tar.gz.

Error Handling

The script will handle methods that are not implemented by the reflection service and will report them at the end of the execution.
