# Agent
Agent is a library used to create commands, inputs and robot services
## Getting Started
- [Commands](#commands) - Commands are functions executed by the bot based on text based pattern matching.
- [Inputs](#inputs) - Inputs are plugins for communication e.g Slack, Telegram, IRC, etc.
- [Services](#services) - Write bots as micro services
## Commands
Commands are functions executed by the bot based on text based pattern matching.
### Write a Command
```go
import "github.com/micro/go-micro/agent/command"
func Ping() command.Command {
usage := "ping"
description := "Returns pong"
return command.NewCommand("ping", usage, desc, func(args ...string) ([]byte, error) {
return []byte("pong"), nil
})
}
```
### Register the command
Add the command to the Commands map with a pattern key that can be matched by golang/regexp.Match
```go
import "github.com/micro/go-micro/agent/command"
func init() {
command.Commands["^ping$"] = Ping()
}
```
### Rebuild Micro
Build binary
```shell
cd github.com/micro/micro
// For local use
go build -i -o micro ./main.go
// For docker image
CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -ldflags '-w' -i -o micro ./main.go
```
## Inputs
Inputs are plugins for communication e.g Slack, HipChat, XMPP, IRC, SMTP, etc, etc.
New inputs can be added in the following way.
### Write an Input
Write an input that satisfies the Input interface.
```go
type Input interface {
// Provide cli flags
Flags() []cli.Flag
// Initialise input using cli context
Init(*cli.Context) error
// Stream events from the input
Stream() (Conn, error)
// Start the input
Start() error
// Stop the input
Stop() error
// name of the input
String() string
}
```
### Register the input
Add the input to the Inputs map.
```go
import "github.com/micro/micro/bot/input"
func init() {
input.Inputs["name"] = MyInput
}
```
### Rebuild Micro
Build binary
```shell
cd github.com/micro/micro
// For local use
go build -i -o micro ./main.go
// For docker image
CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -ldflags '-w' -i -o micro ./main.go
```
## Services
The micro bot supports the ability to create commands as micro services.
### How does it work?
The bot watches the service registry for services with it's namespace. The default namespace is `go.micro.bot`.
Any service within this namespace will automatically be added to the list of available commands. When a command
is executed, the bot will call the service with method `Command.Exec`. It also expects the method `Command.Help`
to exist for usage info.
The service interface is as follows and can be found at [go-micro/agent/proto](https://github.com/micro/go-micro/agent/blob/master/proto/bot.proto)
```
syntax = "proto3";
package go.micro.bot;
service Command {
rpc Help(HelpRequest) returns (HelpResponse) {};
rpc Exec(ExecRequest) returns (ExecResponse) {};
}
message HelpRequest {
}
message HelpResponse {
string usage = 1;
string description = 2;
}
message ExecRequest {
repeated string args = 1;
}
message ExecResponse {
bytes result = 1;
string error = 2;
}
```
### Example
Here's an example echo command as a microservice
```go
package main
import (
"fmt"
"strings"
"github.com/micro/go-micro"
"golang.org/x/net/context"
proto "github.com/micro/go-micro/agent/proto"
)
type Command struct{}
// Help returns the command usage
func (c *Command) Help(ctx context.Context, req *proto.HelpRequest, rsp *proto.HelpResponse) error {
// Usage should include the name of the command
rsp.Usage = "echo"
rsp.Description = "This is an example bot command as a micro service which echos the message"
return nil
}
// Exec executes the command
func (c *Command) Exec(ctx context.Context, req *proto.ExecRequest, rsp *proto.ExecResponse) error {
rsp.Result = []byte(strings.Join(req.Args, " "))
// rsp.Error could be set to return an error instead
// the function error would only be used for service level issues
return nil
}
func main() {
service := micro.NewService(
micro.Name("go.micro.bot.echo"),
)
service.Init()
proto.RegisterCommandHandler(service.Server(), new(Command))
if err := service.Run(); err != nil {
fmt.Println(err)
}
}
```

Go API is a pluggable API framework driven by service discovery to help build powerful public API gateways.
## Overview
The Go API library provides api gateway routing capabilities. A microservice architecture decouples application logic into
separate service. An api gateway provides a single entry point to consolidate these services into a unified api. The
Go API uses routes defined in service discovery metadata to generate routing rules and serve http requests.
<img src="https://micro.mu/docs/images/go-api.png?v=1" alt="Go API" />
Go API is the basis for the [micro api](https://micro.mu/docs/api.html).

# Go Proxy [![License](https://img.shields.io/:license-apache-blue.svg)](https://opensource.org/licenses/Apache-2.0) [![GoDoc](https://godoc.org/github.com/micro/go-proxy?status.svg)](https://godoc.org/github.com/micro/go-proxy)
Go Proxy is a proxy library for Go Micro.
## Overview
Go Micro is a distributed systems framework for client/server communication. It handles the details
around discovery, fault tolerance, rpc communication, etc. We may want to leverage this in broader ecosystems
which make use of standard http or we may also want to offload a number of requirements to a single proxy.
## Features
- **Transparent Proxy** - Proxy requests to any micro services through a single location. Go Proxy enables
you to write Go Micro proxies which handle and forward requests. This is good for incorporating wrappers.
- **Single Backend Router** - Enable the single backend router to proxy directly to your local app. The proxy
allows you to set a router which serves your backend service whether its http, grpc, etc.
- **Protocol Aware Handler** - Set a request handler which speaks your app protocol to make outbound requests.
Your app may not speak the MUCP protocol so it may be easier to translate internally.
- **Control Planes** - Additionally we support use of control planes to offload many distributed systems concerns.
* [x] [Consul](https://www.consul.io/docs/connect/native.html) - Using Connect-Native to provide secure mTLS.
* [x] [NATS](https://nats.io/) - Fully leveraging NATS as the control plane and data plane.
