1 # gRPC-Go 2 3 [](https://travis-ci.org/grpc/grpc-go) [](https://godoc.org/google.golang.org/grpc) [](https://goreportcard.com/report/github.com/grpc/grpc-go) 4 5 The Go implementation of [gRPC](https://grpc.io/): A high performance, open source, general RPC framework that puts mobile and HTTP/2 first. For more information see the [gRPC Quick Start: Go](https://grpc.io/docs/quickstart/go.html) guide. 6 7 Installation 8 ------------ 9 10 To install this package, you need to install Go and setup your Go workspace on your computer. The simplest way to install the library is to run: 11 12 ``` 13 $ go get -u google.golang.org/grpc 14 ``` 15 16 Prerequisites 17 ------------- 18 19 This requires Go 1.6 or later. Go 1.7 will be required soon. 20 21 Constraints 22 ----------- 23 The grpc package should only depend on standard Go packages and a small number of exceptions. If your contribution introduces new dependencies which are NOT in the [list](http://godoc.org/google.golang.org/grpc?imports), you need a discussion with gRPC-Go authors and consultants. 24 25 Documentation 26 ------------- 27 See [API documentation](https://godoc.org/google.golang.org/grpc) for package and API descriptions and find examples in the [examples directory](examples/). 28 29 Performance 30 ----------- 31 See the current benchmarks for some of the languages supported in [this dashboard](https://performance-dot-grpc-testing.appspot.com/explore?dashboard=5652536396611584&widget=490377658&container=1286539696). 32 33 Status 34 ------ 35 General Availability [Google Cloud Platform Launch Stages](https://cloud.google.com/terms/launch-stages). 36 37 FAQ 38 --- 39 40 #### Compiling error, undefined: grpc.SupportPackageIsVersion 41 42 Please update proto package, gRPC package and rebuild the proto files: 43 - `go get -u github.com/golang/protobuf/{proto,protoc-gen-go}` 44 - `go get -u google.golang.org/grpc` 45 - `protoc --go_out=plugins=grpc:. *.proto` 46
