[英]Bootstrap JS not loading in Symfony 5 with Encore
我在使用 Symfony 5、安可、刺激等加載 Bootstrap 的 js 時遇到困難......
jquery、popper、corejs 等都已安裝,並且至少 jquery 正在工作...
app.scss 和 app.js 似乎使用 sass、postcss 和 babel 編譯得很好,包括 Bootstrap 的 CSS。 只是 Bootstrap 的 JS 不存在,所以沒有下拉菜單等。
資產/app.js
// any CSS you import will output into a single css file (app.css in this case)
import './styles/app.scss';
// start the Stimulus application
import './bootstrap';
資產/引導程序,js
import { startStimulusApp } from '@symfony/stimulus-bridge';
// Registers Stimulus controllers from controllers.json and in the controllers/ directory
export const app = startStimulusApp(require.context(
'@symfony/stimulus-bridge/lazy-controller-loader!./controllers',
true,
/\.(j|t)sx?$/
));
// register any custom, 3rd party controllers here
// app.register('some_controller_name', SomeImportedController);
注意: assets/controllers 下沒有具體的 controller
webpack.config.js
const Encore = require('@symfony/webpack-encore');
// Manually configure the runtime environment if not already configured yet by the "encore" command.
// It's useful when you use tools that rely on webpack.config.js file.
if (!Encore.isRuntimeEnvironmentConfigured()) {
Encore.configureRuntimeEnvironment(process.env.NODE_ENV || 'dev');
}
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
*
* Each entry will result in one JavaScript file (e.g. app.js)
* and one CSS file (e.g. app.css) if your JavaScript imports CSS.
*/
.addEntry("app", "./assets/app.js")
// enables the Symfony UX Stimulus bridge (used in assets/bootstrap.js)
.enableStimulusBridge('./assets/controllers.json')
// When enabled, Webpack "splits" your files into smaller pieces for greater optimization.
.splitEntryChunks()
// will require an extra script tag for runtime.js
// but, you probably want this, unless you're building a single-page app
.enableSingleRuntimeChunk()
/*
* 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())
.configureBabel((config) => {
config.plugins.push("@babel/plugin-proposal-class-properties");
})
// enables @babel/preset-env polyfills
.configureBabelPresetEnv((config) => {
config.useBuiltIns = "usage";
config.corejs = 3;
})
// enables Sass/SCSS support
.enableSassLoader()
// enable PostCSS
.enablePostCssLoader();
// uncomment if you use TypeScript
//.enableTypeScriptLoader()
// uncomment if you use React
//.enableReactPreset()
// uncomment to get integrity="..." attributes on your script & link tags
// requires WebpackEncoreBundle 1.4 or higher
//.enableIntegrityHashes(Encore.isProduction())
// uncomment if you're having problems with a jQuery plugin
// .autoProvidejQuery()
module.exports = Encore.getWebpackConfig();
package.json(僅依賴項)

如何進一步排除故障?
您不會在任何地方import
bootstrap
。 您有自己的名為bootstrap.js
的文件,但它會做一些不相關的刺激事情。
您需要添加import 'bootstrap';
到app.js
。
