Modern Perl web applications use frameworks like Mojolicious or Dancer2 for routing and request handling, Test::More for unit and integration tests, and Carton for reproducible dependency management. Enforce strict, warnings, and utf8 pragmas; use Perl::Critic for code quality; and maintain high test coverage as part of your development workflow.

Use DBI for direct database access or DBIx::Class for object-relational mapping. Both integrate with modern Perl frameworks and support parameterized queries to prevent SQL injection. Combine with Carton to lock database driver versions and ensure consistency across environments.

Apply Perl::Critic to enforce coding standards, write tests with Test::More to achieve high coverage, and use strict mode with warnings enabled. Modern Perl features like subroutine signatures (via feature 'signatures') improve readability. Carton locks dependency versions to prevent unexpected behavior from updates.

Mojolicious and Dancer2 are separate web frameworks with different design philosophies. Mojolicious is full-featured and batteries-included; Dancer2 is lightweight and minimal. Choose based on project scope—Mojolicious for complex applications, Dancer2 for simpler APIs or microservices.

Signatures require Perl 5.20+ and the 'feature' pragma. Taint mode activates with the -T flag on the shebang or perl invocation and is essential for web applications handling user input. Both are enforced by this Skill's standards for security and code clarity.

Use Carton to create a cpanfile listing all dependencies with pinned versions, then generate cpanfile.lock for reproducible installs. Distribute both files with your module so users run 'carton install' to replicate your exact dependency tree.
