gRPC – An RPC library and framework

gRPC is a modern, open source, high-performance remote procedure call (RPC)
framework that can run anywhere. gRPC enables client and server applications to
communicate transparently, and simplifies the building of connected systems.

 To start using gRPC

To maximize usability, gRPC supports the standard method for adding dependencies
to a user's chosen language (if there is one). In most languages, the gRPC
runtime comes as a package available in a user's language package manager.

For instructions on how to use the language-specific gRPC runtime for a project,
please refer to these documents

-   C++: follow the instructions under the src/cpp directory
-   C/.NET: NuGet packages
    Grpc.Net.Client, Grpc.AspNetCore.Server
-   Dart: pub package grpc
-   Go: go get google.golang.org/grpc
-   Java: Use JARs from Maven Central
    Repository
-   Kotlin: Use JARs from Maven Central
    Repository
-   Node: npm install @grpc/grpc-js
-   Objective-C: Add gRPC-ProtoRPC dependency to podspec
-   PHP: pecl install grpc
-   Python: pip install grpcio
-   Ruby: gem install grpc
-   WebJS: follow the grpc-web instructions

Per-language quickstart guides and tutorials can be found in the
documentation section on the grpc.io website. Code
examples are available in the examples directory.

Precompiled bleeding-edge package builds of gRPC master branch's HEAD are
uploaded daily to packages.grpc.io.

 To start developing gRPC

Contributions are welcome!

Please read How to contribute which will guide you through
the entire workflow of how to build the source code, how to run the tests, and
how to contribute changes to the gRPC codebase. For detailed C++ build instructions,
see Building from source. The "How to contribute" document
also contains info on how the contribution process works and contains best
practices for creating contributions.

 Troubleshooting

Sometimes things go wrong. Please check out the
Troubleshooting guide if you are experiencing issues with
gRPC.

 About This Repository

This repository contains source code for gRPC libraries implemented in multiple
languages written on top of a shared C++ core library src/core.

Libraries in different languages may be in various states of development. We are
seeking contributions for all of these libraries:
