felix

Felix is a CLI to quickly create service based on templates. For now it uses a default template but soon it will be able to accept all.

installing

go get -u github.com/felix-cli/felix/...

templates

• https://github.com/felix-cli/grpc-service.felix

Quick Start

Environment set up

Ensure Go is installed and /usr/local/go/bin and $HOME/go/bin is in your PATH environment variable.

Ref = https://golang.ir/doc/install

Example: export PATH="$PATH:/usr/local/go/bin:$HOME/go/bin"

Ensure your GOPATH is set with something like:

export GOPATH="$GOPATH:$HOME/go"

Install Protobuf and GRPC Gateway

Install protobuf for MacOS using brew:

brew install protobuf

Install GRPC Gateway:

https://github.com/grpc-ecosystem/grpc-gateway#installation

go get -u github.com/grpc-ecosystem/grpc-gateway/protoc-gen-grpc-gateway
go get -u github.com/grpc-ecosystem/grpc-gateway/protoc-gen-swagger
go get -u github.com/golang/protobuf/protoc-gen-go

Install Felix

go get -u github.com/felix-cli/felix/...

Example usage

felix version

Output:

felix version felix0.1.2%

Make a test directory that will house your new Go GRPC project:

mkdir ~/test-felix
cd ~/test-felix`

Initialize a project

felix fixit

Output:

Proj [update]: test
Org [update_me]: tester
All done!

Run main.go

make run

Output:

. . .
{"level":"info","ts":1572414251.498708,"caller":"felix/main.go:64","msg":"Starting gRPC server on port 8080"}
{"level":"info","ts":1572414251.4988759,"caller":"felix/main.go:74","msg":"Starting http server on port 8000"}

In another terminal window:

curl localhost:8000/hello_world

Output:

{"response":{"msg":"Welcome to the future!"}}%

Press control-c or close the terminal windown you are running the make run to stop the server.

Now you can make some changes. For example, edit the Server and change the greeting from Welcome to the future! to Yo, Welcome to the future!

vi server/handler.go

Import and compile with the annotation.proto via the Makefile

make proto

Output:

protoc -I/usr/local/include -I. -I/Users/tester/go/src -I/Users/tester/go/src/github.com/grpc-ecosystem/grpc-gateway/third_party/googleapis --go_out=plugins=grpc:. --grpc-gateway_out=logtostderr=true:. --swagger_out=logtostderr=true:. services/*/*.proto;

Run main.go

make run

Output:

go run main.go
{"level":"info","ts":1572416470.9507,"caller":"felix/main.go:64","msg":"Starting gRPC server on port 8080"}
{"level":"info","ts":1572416470.9508128,"caller":"felix/main.go:74","msg":"Starting http server on port 8000"}

In another terminal window run:

curl localhost:8000/hello_world

Output:

{"response":{"msg":"Yo, Welcome to the future!"}}%

Press control-c or close the terminal windown you are running the make run to stop the server.
