Spiral GRPC Application Skeleton

Spiral Framework is a High-Performance PHP/Go Full-Stack framework and group of over sixty PSR-compatible components. The Framework execution model based on a hybrid runtime where some services (GRPC, Queue, WebSockets, etc.) handled by Application Server RoadRunner and the PHP code of your application stays in memory permanently (anti-memory leak tools included).

Server Requirements

Make sure that your server is configured with following PHP version and extensions:

• PHP 8.0+, 64bit
• mb-string extension
• PDO Extension with desired database drivers
• Install protobuf-ext to gain higher performance.

Application Bundle

Application bundle includes the following components:

• GRPC Server server based on RoadRunner
• Console commands via Symfony/Console
• Queue support for AMQP, Beanstalk, Amazon SQS, in-Memory
• DBAL and migrations support
• Monolog, Dotenv
• Prometheus metrics
• Cycle DataMapper ORM

Installation

composer create-project spiral/app-grpc

Application server will be downloaded automatically (php-curl and php-zip required).

Once the application is installed you can ensure that it was configured properly by executing:

$ php ./app.php configure

Running GRPC Server

In order to run GRPC server you must specify location of server key and certificate in .rr.yaml file:

grpc:
    listen: "tcp://0.0.0.0:50051"
    proto:
        - "proto/service.proto"
    tls:
        key: "app.key"
        cert: "app.crt"
    pool:
        num_workers: 2
        supervisor:
            max_worker_memory: 100

To issue local certificate:

$ openssl req -newkey rsa:2048 -nodes -keyout app.key -x509 -days 365 -out app.crt

To start application server execute:

$ ./rr serve

On Windows:

$ rr.exe serve

You can test your endpoints using any GRPC client. For example using grpcui:

$ grpcui -insecure -import-path ./proto/ -proto service.proto localhost:50051

Make sure to use -insecure option while using a self-signed certificate.

Generating Services

In order to compile protobuf declarations into service code make sure to install:

• protoc compiler
• protoc-gen-php-grpc plugin

To update or generate service code for your application run:

$ php ./app.php grpc:generate

Generated code will be available in app/src/Service. Implemented service will be automatically registered in your application.
