Services and database connection providers

Stackato-assist can easily provide database connections by only passing in the service name you gave when creating the service, or as defined in stackato.yml:

  // Database services
  // -----------------

  // true / false
  stackato.hasMongoDB
  stackato.hasRedis
  stackato.hasMySQL
  stackato.hasPostgreSQL

  // Get a service by name
  // ---------------------
  stackato.getService('myMongodb1', function(err, service){
      console.log(service.host);
      console.log(service.db);
      // ... //
  });

  // Persistent Filesystem service
  // -----------------------------
  stackato.hasFileSystem // true/false
  stackato.fileSystemPath // /path/to/fs

  // Harbor external port service
  // ----------------------------
  stackato.hasHarbor // true/false
  stackato.harborPort // port #

  // MongoDB connection helper
  // -------------------------
  stackato.connectMongoDB('serviceName', function(err, client){
      //client.collection(...)
  });

  // Redis connection helper
  // -------------------------
  stackato.connectRedis('serviceName', function(err, client){
      //client.set("string key", "string val", redis.print);
      // ...
  });

  // PostgreSQL connection helper
  // -------------------------
  if(stackato.hasPostgreSQL){
    stackato.connectPostgreSQL('x3p', function(err, client, pg){
      client.query("SELECT NOW() as when", function(err, result) {
        console.log("Row count: %d",result.rows.length);  // 1
        console.log("Current year: %d", result.rows[0].when.getFullYear());

        pg.connect(function(err, clientTwo){
          // clientTwo.query(...) a new client object using connection params already set
          // by stackato-assist
        });

        //pg.end(); //terminate the client pool, disconnecting all clients
      });
    });
  }

  // MySQL connection helper
  // -------------------------
  if(stackato.hasMySQL){
    stackato.connectMySQL('x4m', function(err, conn){
      connection.query('SELECT 1 + 1 AS solution', function(err, rows, fields) {
        if (err) throw err;
         console.log('The solution is: ', rows[0].solution);
      });
      // connection.end();
    });
  }
