1 gRPC - An RPC library and framework
2 ===================================
4 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.

21 To maximize usability, gRPC supports the standard method for adding dependencies to a user's chosen language (if there is one).
22 In most languages, the gRPC runtime comes as a package available in a user's language package manager.
24 For instructions on how to use the language-specific gRPC runtime for a project, please refer to these documents
26 * [C++](src/cpp): follow the instructions under the `src/cpp` directory
27 * [C#](src/csharp): NuGet package `Grpc`
28 * [Dart](https://github.com/grpc/grpc-dart): pub package `grpc`
29 * [Go](https://github.com/grpc/grpc-go): `go get google.golang.org/grpc`
30 * [Java](https://github.com/grpc/grpc-java): Use JARs from Maven Central Repository
31 * [Kotlin](https://github.com/grpc/grpc-kotlin): Use JARs from Maven Central Repository
32 * [Node](https://github.com/grpc/grpc-node): `npm install grpc`
33 * [Objective-C](src/objective-c): Add `gRPC-ProtoRPC` dependency to podspec
34 * [PHP](src/php): `pecl install grpc`
35 * [Python](src/python/grpcio): `pip install grpcio`
36 * [Ruby](src/ruby): `gem install grpc`
37 * [WebJS](https://github.com/grpc/grpc-web): follow the grpc-web instructions
39 Per-language quickstart guides and tutorials can be found in the [documentation section on the grpc.io website](https://grpc.io/docs/). Code examples are available in the [examples](examples) directory.
41 Precompiled bleeding-edge package builds of gRPC `master` branch's `HEAD` are uploaded daily to [packages.grpc.io](https://packages.grpc.io).
43 # To start developing gRPC
45 Contributions are welcome!
47 Please read [How to contribute](CONTRIBUTING.md) 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
49 The "How to contribute" document also contains info on how the contribution process works and contains best practices for creating contributions.
53 Sometimes things go wrong. Please check out the [Troubleshooting guide](TROUBLESHOOTING.md) if you are experiencing issues with gRPC.
57 See the [Performance dashboard](https://performance-dot-grpc-testing.appspot.com/explore?dashboard=5652536396611584) for performance numbers of master branch daily builds.
