# Proxy Sidecar
The [micro proxy](https://github.com/micro/micro/tree/master/proxy) provides [go-micro](https://github.com/asim/go-micro) features as http endpoints.
This directory contains examples for using the proxy with various languages.
## Usage
See details below
### Run Proxy
```
micro proxy
```
Or with http proxy handler
```
micro proxy --handler=http
```
### Service
Run server
```
{python, ruby} {http, rpc}_server.{py, rb}
```
Run client
```
{python, ruby} {http, rpc}_client.{py, rb}
```
## Examples
Each language directory {python, ruby, ...} contains examples for the following:
- Registering Service
- JSON RPC Server and Client
- HTTP Server and Client

# Go
This Go example uses vanilla net/http and the proxy
- proxy.go: methods to call proxy
- rpc_{client,server}.go: RPC client/server
- http_{client,server}.go: HTTP client/server
## RPC Example
Run proxy
```shell
micro proxy
```
Run server
```shell
# serves Say.Hello
go run rpc_server.go proxy.go
```
Run client
```shell
# calls go.micro.srv.greeter Say.Hello
go run rpc_client.go proxy.go
```
## HTTP Example
Run proxy with proxy handler
```shell
micro proxy --handler=http
```
Run server
```shell
# serves /greeter
go run http_server.go proxy.go
```
Run client
```shell
# calls /greeter
go run http_client.go proxy.go
```
