cassandra-installer v1.1.2

Cassandra Installer

This package is a utility that provides the ability to use Cassandra in an embedded way for your node.js applications. The process works as follows:

• Select the package version of cassandra
• Download Cassandra (It will fetch from the nearest mirror)
• Install cassandra
• Start Cassandra
• Stop Cassandra
• Configure your logger instance for the module

Example Usage

'use strict';    
    
const CassandraInstaller = require('cassandra-installer'),
      winston            = require('winston');
    
/* Create the logging levels, if none provided it will revert to the default console logger */

var transports = [
  new (winston.transports.Console)(),
  new (winston.transports.File)({ filename: '/tmp/cassandra-installer.log' })
];

var options = {
  destination : '/tmp',
  version : '3.5',
  dbName : 'test_db',
  transports : transports
};

/* Create a new installer that will download cassandra 3.4 in /tmp */ 
var installer = new CassandraInstaller(options);

    
/* Download cassandra */
installer.download((err, data) => {
  /* Install cassandra */
  installer.install((err, data) => {
  
    /* Start cassandra */
    installer.start();
    
    /* Create the keyspace that was defined in option */
    installer.createKeyspace(err =>{
      
      /* Drop the db */
      installer.dropKeyspace(err => {
      
        /* Stop cassandra */
        installer.stop();
        
        /*Cleanup */
              setTimeout(function() { //allow 10 seconds for cassandra to shutdown gracefully
                installer.uninstall(err => {
                  if(err) console.log(err);
                });
              }, 10000);
      });
    );
  });
});

Note : Make sure you have the Java runtime 1.8.x installed so that Cassandra runs.

This module works on MacOS X and all flavors of *nix
