README

A simple PHP library to convert a protoset file to proto files.

If you're here, you likely attempted to use a gRPC API and need to generate a PHP client. However, you may be stuck because you have a protoset file instead of a proto file.

This library will assist you in converting the protoset file to proto files.

It works well with gRPC servers that have the reflection service enabled. To learn more, check out the use case example below.

🚀 Installation

composer require srwiez/grpc-protoset

📚 Usage

Either use the ProtosetConverter class directly.

use SRWieZ\GrpcProtoset\ProtosetConverter;

$protoset = new ProtosetConverter();
$protoset->setOutputDir('./proto');
$protoset->convert('starlink.protoset');

or use the script provided by the package.

php cli/converter.php "starlink.protoset" ./proto

or if you have installed the package globally, you can use the following command:

protoset-converter "starlink.protoset" ./proto

🎁 Use case example (Starlink)

How to generate a PHP client for the Starlink API.

You will need to install the following dependencies:

brew install protobuf
brew install grpc
brew install grpcurl

First, get the protoset file from your Starlink device.

grpcurl -plaintext -protoset-out "starlink.protoset" "192.168.100.1:9200" describe SpaceX.API.Device.Device

Then, convert the protoset file to proto files.

protoset-converter "starlink.protoset" ./proto

Finally, generate the PHP client.

protoc --php_out=./generated/ proto/spacex/api/device/device.proto

Bonus, edit your composer.json file to autoload the generated PHP client.

{
    "autoload": {
        "psr-4": {
          "SpaceX\\API\\": "generated/SpaceX/API",
          "GPBMetadata\\Spacex\\Api\\": "generated/GPBMetadata/Spacex/Api"
        }
    }
}

📋 TODO

Contributions are welcome!

• Write tests by using the starlink protoset file
