Examples

	var ConnectionStringBuilder = require('node-connection-string-builder');
	var sc = new ConnectionStringBuilder('Data Source=.;User ID=foo;Password=bar;Initial Catalog=master;');
	console.log(sc.dataSource);
	console.log(sc.userID);
	console.log(sc.password);
	console.log(sc.initialCatalog);

	sc.initialCatalog = 'mydatabase';
	console.log(sc.connectionString);

Output:

.

Add new property to connection string.

remove(key)

Remove property from connection string.

clear()

setValue(key, value)

Sets property in connection string to a particular value.

If propery doesn't exists, it would be created.

containsKey(key)

##Properties

###connectionString

Gets or sets a string representation of the connection string properties.

###keys (Array, readonly)

Returns collection of property names from connection string.

##Helper properties

Helper properties allows you to manipulate the content of connection string.

Declares the application workload type when connecting to a database in an SQL Server Availability Group.

###applicationName

Gets or sets the name of the application associated with the connection string.

###asynchronousProcessing

Gets or sets a Boolean value that indicates whether asynchronous processing is allowed by the connection created by using this connection string.

###attachDBFilename

Gets or sets a string that contains the name of the primary data file. This includes the full path name of an attachable database.

###connectTimeout

Gets or sets the length of time (in seconds) to wait for a connection to the server before terminating the attempt and generating an error.

###currentLanguage

Gets or sets the SQL Server Language record name.

###dataSource

Gets or sets the name or network address of the instance of SQL Server to connect to.

###encrypt

Gets or sets a Boolean value that indicates whether SQL Server uses SSL encryption for all data sent between the client and server if the server has a certificate installed.

###enlist

Gets or sets a Boolean value that indicates whether the SQL Server connection pooler automatically enlists the connection in the creation thread's current transaction context.

###failoverPartner

Gets or sets the name or address of the partner server to connect to if the primary server is down.

###multiSubnetFailover

If your application is connecting to an AlwaysOn availability group (AG) on different subnets, setting MultiSubnetFailover=true provides faster detection of and connection to the (currently) active server. For more information about SqlClient support for Always On Availability Groups, see SqlClient Support for High Availability, Disaster Recovery.

###networkLibrary
