Usage

Example application using the defaults

Example application with PostgreSQL

With Express 3 or Connect

Options

• tablename='sessions' Tablename to use. Defaults to 'sessions'.
• sidfieldname='sid' Field name in table to use for storing session ids. Defaults to 'sid'.
• knex knex instance to use. Defaults to a new knex instance, using sqlite3 with a file named 'connect-session-knex.sqlite'
• createtable if the table for sessions should be created automatically or not.
• clearInterval milliseconds between clearing expired sessions. Defaults to 60000.
• disableDbCleanup disables the automatic clearing of expired sessions. Defaults to false.

If the table does not exist in the schema, this module will attempt to create it unless the 'createtable' option is false.

If a knex instance is not provided, this module will attempt to create a sqlite3 database, with a file named 'connect-session-knex.sqlite', in the working directory of the process.
