NAME

Plack::App::DBI::Gofer - server side http transport for DBI-Gofer using PSGI

SYNOPSIS

        use Plack::App::DBI::Gofer;
        my $app = Plack::App::DBI::Gofer->new( config => {
                %DBI_Gofer_Execute_config_params
        })->to_app;
        
        # or map a path to a forced dsn
        use Plack::Builder;
        builder {
                mount '/mydb' => Plack::App::DBI::Gofer->new( config => {
                        forced_connect_dsn => 'dbi:SQLite:dbname=mydb.db',
                })->to_app;
        };

For a corresponding client-side transport see DBD::Gofer::Transport::http.

DESCRIPTION

This module implements a DBD::Gofer server-side http transport through PSGI.

This enables DBI to connect to databases through your PSGI-enabled HTTP server.

CONFIGURATION

Gofer Configuration

Rather than provide a DBI proxy that will connect to any database as any user, you may well want to restrict access to just one or a few databases.

Or perhaps you want the database passwords to be stored only in your app.psgi so you don't have to maintain them in all your clients.

A typical usage might be to define configurations for each specific database being used and then define a coresponding location for each of those. That would also allow standard http location access controls to be used

That approach can also provide a level of indirection by avoiding the need for the clients to know and use the actual DSN. The clients can just connect to the specific gofer url with an empty DSN. This means you can change the DSN being used without having to update the clients.

This enables the use of forking PSGI web servers and handlers, including Starman, Monoceros and Gazelle as caching, stateless database proxies.

At this time, this application doesn't support asynchronous, event driven servers such as Twiggy.

config

Set to a hash of DBI::Gofer::Execute options, optional.

DIFFERENCES FROM DBI::Gofer::Transport::mod_perl

TO DO

  • Add a lighter client side http transport that doesn't require installing mod_perl

    Possibly using HTTP::Tiny or HTTP::Lite

  • More tests

  • Support http authorization (Basic and Digest)

  • Support PSGI streaming and async.
