5. Что такое
Mojolicious?

6. Что такое Mojolicious?
• Pure Perl веб-фреймворк
• Без зависимостей (с версии Perl 5.8.1)
• Объектно-ориентированное API (без скрытой магии)
• Поддержка HTTP 1.1, WebSocket, IPv6, SSL, IDNA
• Поддержка CGI, FastCGI, PSGI, Daemon и Prefork
• Веб-фреймворки: Mojo, Mojolicious и Mojolicious::Lite

7. «Fresh code,
based upon years of
expirience developing
Catalyst»
