## How to install Vertigo
You can install Vertigo using Node Package Manager (npm):
```
npm install vertigo
```
## Features
* Supports Request/Reply communication.
* Supports Send without Reply communication.
* Supports multiple server using round robin.
* Fault tolerant: clients will reconnect to servers even if server goes down and comes back later.
* Extremely fast (disables TCP Nagle's algorithm).
* Zero dependencies on other libraries.
* Block non-desired IPs.
## Examples
### Request/Reply: Server with one client
#### Server
```js
// Modules
var vertigo = require('vertigo');
// Create server
var server = vertigo.createServer( 8000 );
// Listen petitions
server.on( 'hello', function( name, callback ){
callback( null, 'Hi ' + name + ', I am the server' );
});
```
#### Client
```js
// Modules
var vertigo = require('vertigo');
// Create client
var client = vertigo.createClient( 8000 );
// Make a petition
client.request( 'hello', 'John', function( error, response ){
console.log( 'Server says', response );
});
```
### Request/Reply: 2 server with one client (Round robin)
#### Server 1
```js
// Modules
var vertigo = require('vertigo');
// Create server
var server = vertigo.createServer( 8000 );
// Listen petitions
server.on( 'hello', function( name, callback ){
callback( null, 'Hi ' + name + ', I am the server 1' );
});
```
#### Server 2
```js
// Modules
var vertigo = require('vertigo');
// Create server
var server = vertigo.createServer( 8001 );
// Listen petitions
server.on( 'hello', function( name, callback ){
callback( null, 'Hi ' + name + ', I am the server 2' );
});
```
#### Client
```js
// Modules
var vertigo = require('vertigo');
// Create client
var client = vertigo.createClient( 8000, 8001 );
// Make a petition
client.request( 'hello', 'John', function( error, response ){
console.log( 'Server says', response );
});
```
### Send: Server with one client
#### Server
```js
// Modules
var vertigo = require('vertigo');
// Create server
var server = vertigo.createServer( 8000 );
// Listen petitions
server.on( 'hello', function( name ){
console.log( 'I received a message from ' + name );
});
```
#### Client
```js
// Modules
var vertigo = require('vertigo');
// Create client
var client = vertigo.createClient( 8000 );
// Make a petition
client.send( 'hello', 'John' );
```
### Block non-desired connections from unknown IPs
#### Server
```js
// Modules
var vertigo = require('vertigo');
// Create server
var server = vertigo.createServer(
8000,
null, // Host definition, use falsy values for autoconfiguration
[ '127.0.0.1', '192.168.1.42' ] // Accepted IPs. If it isn't defined all IPs are accepted.
);
// Listen petitions
server.on( 'hello', function( name ){
console.log( 'I received a message from ' + name );
});
```
## Migrating from hermod
You can use Vertigo safely, currently the API is the same in both libraries.
