nodejs-directvps

Access the DirectVPS API from your Node.js code

Table of contents

Installation

From npm

To install the module from the npm repository run this:

npm install directvps

And then link inside your code with:

var directvps = require('directvps')

From source

Install directly from Github source:

git clone https://github.com/fvdm/nodejs-directvps.git

And load in your code:

var directvps = require('/path/to/nodejs-directvps')

Setup

In order to use the API you need to have an API access private-key and certificate. Refer to the documentation for details. After loading the module with require() set the key and certificate with setup().

Settings

Name              Type      Description                          Example
---------------   -------   ----------------------------------   ---------
privateKey        string    The private-key in plain text.
certificate       string    The certificate in plain text.
privateKeyFile    string    Path to the private-key file.        ~/api.key
certificateFile   string    Path to certificate file.            ~/api.crt
verifyCert        boolean   Validate server certificate          true
                            agains trusted CA's.
debugResponse     function  Receive communication details.

Load from files

This is the simple way, if you have access to a filesystem.

directvps.setup({
    privateKeyFile:     '/path/to/private.key',
    certificateFile:    '/path/to/shared-certificate.crt'
})

Load directly

Or you can load the private-key and certificate directly, ie. from a database.

directvps.setup({
    privateKey:         '-----BEGIN RSA PRIVATE KEY-----',
    certificate:        '-----BEGIN CERTIFICATE-----'
})

Usage

This module is event based, meaning all functions require a callback function parameter to process the result. All methods from the API are implemented directly, but for VPS specific methods a shorthand is also available. The two samples below highlight both methods.

The examples below are based on the NPM install. If you rather directly use the source file use the require() replacement above.

Direct method

In this example the API method get_vpslist is called, the callback function loops through the resulting servers object and for each server it writes a log to the console.

var directvps = require('directvps')

directvps.get_vpslist( function( servers ) {
    for( var s in servers ) {
        var vps = servers[s]
        console.log( 'VPS '+ vps.vpsid +' allows '+ vps.traffic 'GB traffic' )
    }
})

Shorthand method

In this example the vps shorthand method is called to get the functions for server 123. Then its sub-function .details is called to get the server's information. In the background the script requests all servers with get_vpslist, loops through them until vpsid 123 is found and then send the result to the callback function. In this case, to write a line to the console.

var directvps = require('directvps')

// one line
directvps.vps(123).details( function( details ) {
    console.log( 'VPS '+ vps.vpsid +' allows '+ vps.traffic 'GB traffic' )
})

// or via a variable
var vps = directvps.vps(123)
vps.details( function( details ) {
    console.log( 'VPS '+ vps.vpsid +' allows '+ vps.traffic 'GB traffic' )
})

Extended example

Shutdown all servers from one client, these may be identified with 'client: 123' in their tag.

// First get the list of all servers
directvps.get_vpslist( function( servers ) {

    // walk through each of them
    for( var vpsid in servers ) {

        // request server specific functions
        var vps = directvps.vps( vpsid )

        // and its information
        vps.details = servers[ vpsid ]

        // do the matching
        if( vps.details.tag.match( /^client: 123\, / ) ) {

            // found one, shutdown gracefully
            vps.shutdown( function( plan ) {

                // report status to console
                var status = 'Server '+ vpsid +' shutdown '

                if( plan.error == '0' ) {
                    status += 'planned: ID '+ plan.planningid
                } else {
                    status += 'failed: '+ plan.errormessage
                }

                console.log( status )

            })

        }

    }

})
