[EN] WORKING WITH TWIG IN SYMFONY // “Tips and tWricks”

Twig is really linked with Symfony, but rarely gets love during online conferences.

⚡️ Yet, it's incredibly powerful and useful in many ways, to save source code writing, to achieve common algorithmic operations, etc.

This talk goes through a few interesting things regarding Twig:
🌾 the Twig / Symfony bridge
🌾 good practices with usage (SEO, performance, directory architecture, forms, etc.)
🌾 general information like coding standards, escaping, philosophy, etc.
🌾 how to extend Twig and why you would need to do such a thing
🌾 smart tricks you probably never thought about
🌾 usages and REX on advanced functionalities (caching, translations, etc.)
🌾 real life examples, through OROCommerce, Sylius, Drupal, Symfony UX, etc.

Let's show some love to our favorite templating engine! 💚
