Using bootstrap with Webpack Encore in Symfony 4
Solution 1
There is an error in the template/base.html.twig file in the head. The result of the global asset/js/app.scss in the public/build directory is a app.css file and not a .scss extension file. It is the result of the build of all the javascript files we can find in the assets/js/ directory.
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<title>{% block title %}Welcome!{% endblock %}</title>
{% block stylesheets %}
<link rel="stylesheet" href="{{ asset('build/app.css') }}">
{% endblock %}
</head>
Solution 2
Two Twig helpers from WebpackEncoreBundle can do most of the work for you:
https://symfony.com/doc/current/frontend/encore/simple-example.html#the-import-and-export-statements
{# templates/base.html.twig #}
<!DOCTYPE html>
<html>
<head>
<!-- ... -->
{% block stylesheets %}
{# 'app' must match the first argument to addEntry() in webpack.config.js #}
{{ encore_entry_link_tags('app') }}
<!-- Renders a link tag (if your module requires any CSS)
<link rel="stylesheet" href="/build/app.css"> -->
{% endblock %}
</head>
<body>
<!-- ... -->
{% block javascripts %}
{{ encore_entry_script_tags('app') }}
<!-- Renders app.js & a webpack runtime.js file
<script src="/build/runtime.js"></script>
<script src="/build/app.js"></script> -->
{% endblock %}
</body>
</html>

I would like to use bootstrap with Webpack Encore in Symfony 4.1 but bootstrap does not function. In the template/base.html.twig file in this post, I used some bootstrap classes but it is not taken into account and I don't understand why.
I installed the dependencies I need for bootstrap with yarn:
yarn add bootstrap --dev yarn add jquery --dev yarn add popper.js --dev
template/base.html.twig
In this file, I used the asset function in order to take into account the files: build/app.scss and build/app.js
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <title>{% block title %}Welcome!{% endblock %}</title> {% block stylesheets %} <link rel="stylesheet" href="{{ asset('build/app.scss') }}"> {% endblock %} </head> <body> {% block body %} <nav class="navbar navbar-expand-lg navbar-light bg-light"> <a class="navbar-brand" href="#">Navbar</a> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" ar$ <span class="navbar-toggler-icon"></span> </button> </nav> {% endblock %} {% block javascripts %} <script src="{{ asset('build/app.js') }}"></script> {% endblock %} </body> </html>
In the two following files, I required and imported what I need for bootstrap.
assets/js/app.js
require('../css/app.scss'); var $ = require('jquery'); require('bootstrap');
assets/css/app.scss
@import "~bootstrap/scss/bootstrap";
webpack.config.js
In this file, I used enableSassLoader() in order to activate Sass and autoProvidejQuery() in order to have access to jQuery as a global variable.
var Encore = require('@symfony/webpack-encore'); Encore // directory where compiled assets will be stored .setOutputPath('public/build/') // public path used by the web server to access the output path .setPublicPath('/build') // only needed for CDN's or sub-directory deploy //.setManifestKeyPrefix('build/') /* * ENTRY CONFIG * * Add 1 entry for each "page" of your app * (including one that's included on every page - e.g. "app") * * Each entry will result in one JavaScript file (e.g. app.js) * and one CSS file (e.g. app.css) if you JavaScript imports CSS. */ .addEntry('app', './assets/js/app.js') /* * FEATURE CONFIG * * Enable & configure other features below. For a full * list of features, see: * https://symfony.com/doc/current/frontend.html#adding-more-features */ .cleanupOutputBeforeBuild() .enableBuildNotifications() .enableSourceMaps(!Encore.isProduction()) // enables hashed filenames (e.g. app.abc123.css) .enableVersioning(Encore.isProduction()) // enables Sass/SCSS support .enableSassLoader() // uncomment if you use TypeScript //.enableTypeScriptLoader() // uncomment if you're having problems with a jQuery plugin .autoProvidejQuery() ; module.exports = Encore.getWebpackConfig();
The command yarn encore dev builds everything correctly. But, I don't see the bootstrap theme in the screen.
Thanks in advance,
