Optimising Your Front End Workflow With Symfony, Twig, Bower and Gulp
•
46 gostaram•52,637 visualizações
We take great care in our back end coding workflow, optimising, automating and abstracting as much as is possible. So why don't we do that with our front end code? We'll take a look at some tools to help us take our front end workflow to the next level, and hopefully optimise our load times in the process! We'll be looking at using Twig templates and optimising them for the different areas of your application, integrating Bower and Gulp for managing assets and processing our front-end code to avoid repetitive tasks - looking at how that impacts the typical Symfony workflow.

- 23. Twig
- 25. Insanely powerful Compiled and cached
- 26. Insanely powerful Compiled and cached Often overlooked
- 27. Translate all the things
- 29. But it’s easy to keep them organised
- 31. Article.php /** * The title of the Article * * @var string * * @ORMColumn(type="string", length=255) * * @AssertNotBlank(message="article.title.not_blank") * @AssertLength( * max=255, * maxMessage="article.title.length.max" * ) */ protected $title;
- 32. validators.en.yml article: title: not_blank: You must enter a title length: max: The title cannot be longer than {{ limit }} characters content: not_blank: You must enter some content
- 34. ArticleType.php $builder ->add( 'title', 'text', [ 'label' => 'article.label.title' ] ) For all properties in the form
- 36. forms.en.yml?!
- 37. ArticleType.php /** * {@inheritdoc} */ public function setDefaultOptions(OptionsResolverInterface $resolver) { $resolver->setDefaults([ 'data_class' => 'MDEntityArticle', 'translation_domain' => 'forms' ]); }
- 39. When your translations don’t work…
- 40. CLEAR THE CACHE!
- 41. CLEAR THE CACHE! Even in the dev environment
- 43. Translate everything All titles, actions, single words
- 44. Translate everything All titles, actions, single words Translations per ‘section’
- 45. admin.en.yml article: title: list: All Articles create: Add a New Article action: create: Add New cancel: Cancel
- 46. list.html.twig {% block body %} <h1>{{ 'article.title.list'|trans({}, 'admin') }}</h1> {% if articles %} <ul class="articles"> {% for article in articles %} <li>{{ article.title }}</li> {% endfor %} </ul> {% endif %} <a href="{{ path('admin.article.create') }}”> {{ 'article.action.create'|trans({}, 'admin') }} </a> {% endblock body %}
- 47. Messy
- 50. base.html.twig <!DOCTYPE html> <html> <head> <meta charset="UTF-8" /> <title>{% block title %}Welcome!{% endblock %}</title> {% block stylesheets %}{% endblock %} <link rel="icon" type="image/x-icon" href="{{ asset('favicon.ico') }}" /> </head> <body> {% block body %}{% endblock %} {% block javascripts %}{% endblock %} </body> </html>
- 51. Doesn’t promote great code
- 52. base.html.twig <!doctype html> <!--[if lt IE 7 ]> <html lang="en" class="no-js ie6 lt-ie9 lt-ie8 lt-ie7"> <![endif]--> <!--[if IE 7 ]> <html lang="en" class="no-js ie7 lt-ie9 lt-ie8"> <![endif]--> <!--[if IE 8 ]> <html lang="en" class="no-js ie8 lt-ie9"> <![endif]--> <!--[if IE 9 ]> <html lang="en" class="no-js ie9"> <![endif]--> <!--[if (gt IE 9)|!(IE)]><!--> <html lang="en" class="no-js"><!--<![endif]--> <head> <meta charset="utf-8" /> <title>{% block title %}{% endblock title %}</title> <!-- Set up mobile viewport for responsive design --> <meta name="viewport" content="width=device-width" /> {% block stylesheets %}{% endblock stylesheets %} </head> <body> {% block content %}{% endblock content %} {% block javascripts %}{% endblock javascripts %} </body> </html>
- 53. Gives us a better foundation
- 55. The same HTML structure and assets per ‘section’?
- 58. admin.html.twig {% extends "::base.html.twig" %} {% block title %} {{ 'defaults.title'|trans({}, 'admin') }} {% endblock title %} {% block content %} {% block body %}{% endblock body %} {% endblock content %}
- 59. frontend.html.twig {% extends "::base.html.twig" %} {% block title %}{{ 'defaults.title'|trans }}{% endblock title %} {% block content %} {% block header %}{% endblock header %} {% block body %}{% endblock body %} {% block footer %}{% endblock footer %} {% endblock content %}
- 60. What?!
- 62. list.html.twig {% extends "MDMainBundle:Layouts:admin.html.twig" %} {% block body %} <h1>{{ 'article.title.list'|trans({}, 'admin') }}</h1> {% if articles %} <ul class="articles"> {% for article in articles %} <li>{{ article.title }}</li> {% endfor %} </ul> {% endif %} <a href="{{ path('admin.article.create') }}”> {{ 'article.action.create'|trans({}, 'admin') }} </a> {% endblock body %}
- 63. Given ourselves flexible base
- 64. Given ourselves flexible base All boilerplate code is DRY
- 65. Given ourselves flexible base All boilerplate code is DRY Defaults per ‘section’
- 67. list.html.twig {% extends "MDMainBundle:Layouts:admin.html.twig" %} {% trans_default_domain "admin" %} {% block body %} <h1>{{ 'article.title.list'|trans }}</h1> {% if articles %} <ul class="articles"> {% for article in articles %} <li>{{ article.title }}</li> {% endfor %} </ul> {% endif %} <a href="{{ path('admin.article.create') }}”> {{ 'article.action.create'|trans }} </a> {% endblock body %}
