How To Install libdancer2-plugin-database-perl on Ubuntu 18.04
Introduction
In this tutorial we learn how to install libdancer2-plugin-database-perl on Ubuntu 18.04.
What is libdancer2-plugin-database-perl
libdancer2-plugin-database-perl is:
Dancer2::Plugin::Database Provides an easy way to obtain a connected DBI database handle by simply calling the database keyword within your Dancer2 application
The module returns a Dancer::Plugin::Database::Core::Handle object, which is a subclass of DBI’s `DBI::db’ connection handle object, so it does everything you’d expect to do with DBI, but also adds a few convenience methods.
It takes care of ensuring that the database handle is still connected and
valid. If the handle was last asked for more than
connection_check_threshold' seconds ago, it will check that the connection is still alive, using either the $dbh->ping’ method if the DBD driver
supports it, or performing a simple no-op query against the database if not.
If the connection has gone away, a new connection will be obtained and
returned. This avoids any problems for a long-running script where the
connection to the database might go away.
Care is taken that handles are not shared across processes/threads, so this should be thread-safe with no issues with transactions etc.
