Symfony4 - A new way of developing web applications
This document discusses Symfony 4, highlighting its advantages as a micro framework for developing web applications. It emphasizes the use of Symfony Flex for simplified bundle management, autowiring for service management, and improvements in the overall development experience. Additionally, it touches on the roadmap and community support, noting that while Symfony 4 is easier to start with, mastering it may still present challenges.

- 22. Symfony flex recipies ●Two repositories ● symfony/recipies ○ maintained by Symfony Core Team and holds only recipies for Symfony components and bundles ‘opinionated’ by them ○ Can use alias ● symfony/recipies-contrib ○ Anyone can contribute ○ Cannot use alias @antonioperic

- 26. Directory structure @antonioperic we saygoodby to app.php and app_dev.php — this is now one standard index.php file and environment is set with environmental variable APP_ENV

- 30. Directory structure @antonioperic Flex keepstracks of the recipes it installed in a symfony.lock file, which must be committed to your code repository.
- 31. Bundle-less applications ● Bundlevs no-bundle apps ● All in src folder ○ App/ namespace ○ You should separate, but no need for bundles ● Moving forward to standardisation ● It reduces the perceived complexity, also makes your code feels more decoupled from symfony ● Bundle inheritance mechanisms are deprecated in 3.4 and were removed in 4.0 @antonioperic
- 32. Let’s call thisa small demo - Our task will be to create simple Symfony console application, a web crawler - Steps: - Create new symfony application - composer create-project symfony/skeleton my_project - Add Console component - Add Doctrine - Add Symfony Crawler component - Do some code (we will not do code, idea is just to see the flow of working with Symfony4) @antonioperic
- 33. Create new Symfony4application @antonioperic
- 34. Create new Symfony4application @antonioperic
- 35. Add components ● Composerreq cli ● Composer req doctrine ● Composer req symfony/dom-crawler @antonioperic
- 36. Autowiring ● Introduced inSymfony 3 version ● Autowiring allows you to manage services in the container with minimal configuration ● It reads the type-hints on your constructor (or other methods) and automatically passes the correct services to each method. ● Symfony's autowiring is designed to be predictable: if it is not absolutely clear which dependency should be passed, you'll see an actionable exception. @antonioperic

- 39. Symfony Webpack Encore ●Webpack encore is a simpler way to integrate Webpack into your application ● Step forward after AsseticBundle ● composer require webpack-encore ● It can work outside of Symfony @antonioperic

- 41. DotEnv component ● TheDotenv Component parses .env files to make environment variables stored in them accessible via getenv(), $_ENV or $_SERVER. ● composer require symfony/dotenv @antonioperic

- 46. Updating to Symfony ●It is possible, not even to complex ● Need a little bit of time ● If you are using Symfony2.x, upgrade first to 3.4 @antonioperic
- 47. Symfony 4.1 improvements ●Made csrf_token() useable without forms ● Csv processor for env variables ● Display DotEnv variables in profiler ● Session improvements ● Console improvements ● Workflow improvements ● Messenger component https://symfony.com/blog/symfony-4-1-curated-new- features @antonioperic

- 49. 7 months later ●It is great feeling to works with Symfony4 ● Seems that Fabien and core team are making great progress moving Symfony forward ● I love Flex ● It is seems much more natural to navigate through new code structure and DX is much better ● Symfony community is awesome @antonioperic
- 50. 7 months later ●Symfony is great as microframework ● With higher level of abstraction is more better for prototyping and building things fast ● It will be much easier to start, but maybe even harder to master for newbies (symfony2 wasn’t easy to master) @antonioperic
