PSGI

PSGI (Perl Web Server Gateway Interface) is a specification that defines a standard interface between Perl web applications and web servers. It enables Perl applications to run on various web servers without modification, similar to WSGI for Python or Rack for Ruby. This abstraction allows developers to write web applications that are server-agnostic, improving portability and interoperability.

Also known as: Perl Web Server Gateway Interface, PSGI specification, PSGI/Plack, Plack, Perl WSGI

Why learn PSGI?

Developers should learn PSGI when building web applications in Perl, as it provides a consistent way to deploy apps across different servers like Starman, Twiggy, or Apache with mod_perl. It's essential for modern Perl web development, enabling use of frameworks like Dancer, Mojolicious, or Catalyst, and simplifies testing and deployment in diverse environments.
