javascript - 在 5.7 中将 npm 包安装到 Laravel

Question

我正在尝试将 npm 包安装到我的 Laravel 项目中。因此，我使用 npm install 安装了 npm，然后执行了 npm install masonry-layout 然后我运行了 npm run watch ，它出现在我的 node_modules 中文件夹。

我尝试将 require('masonry-layout'); 添加到我的 app.js 并添加 window.anything = require('masonry-layout'); 或 window._ = require('masonry-layout'); 到我的 bootstrap.js - 我在我的 View 上调用它，如下所示:

var $grid = $('.grid').imagesLoaded( function() {
    $grid.masonry({
        itemSelector: '.grid-item',
        columnWidth: '.grid-sizer',
        percentPosition: true,
        isResizable: true,
        transitionDuration: '0.8s',
        isAnimated: true
    });
});

我的app.js:

require('./bootstrap');
require('masonry-layout');
require('imagesloaded');

bootstrap.js:

window._ = require('lodash');
window.anything = require('masonry-layout');
window.anything = require('imagesloaded');


/**
 * We'll load jQuery and the Bootstrap jQuery plugin which provides support
 * for JavaScript based Bootstrap features such as modals and tabs. This
 * code may be modified to fit the specific needs of your application.
 */

try {
    window.Popper = require('popper.js').default;
    window.$ = window.jQuery = require('jquery');

    require('bootstrap');
} catch (e) {}

/**
 * We'll load the axios HTTP library which allows us to easily issue requests
 * to our Laravel back-end. This library automatically handles sending the
 * CSRF token as a header based on the value of the "XSRF" token cookie.
 */

window.axios = require('axios');

window.axios.defaults.headers.common['X-Requested-With'] = 'XMLHttpRequest';

/**
 * Next we will register the CSRF Token as a common header with Axios so that
 * all outgoing HTTP requests automatically have it attached. This is just
 * a simple convenience so we don't have to attach every token manually.
 */

let token = document.head.querySelector('meta[name="csrf-token"]');

if (token) {
    window.axios.defaults.headers.common['X-CSRF-TOKEN'] = token.content;
} else {
    console.error('CSRF token not found: https://laravel.com/docs/csrf#csrf-x-csrf-token');
}

/**
 * Echo exposes an expressive API for subscribing to channels and listening
 * for events that are broadcast by Laravel. Echo and event broadcasting
 * allows your team to easily build robust real-time web applications.
 */

// import Echo from 'laravel-echo'

// window.Pusher = require('pusher-js');

// window.Echo = new Echo({
//     broadcaster: 'pusher',
//     key: process.env.MIX_PUSHER_APP_KEY,
//     cluster: process.env.MIX_PUSHER_APP_CLUSTER,
//     encrypted: true
// });

是的，我也安装了 imagesLoaded，但这也不起作用。如果我将 cdn 包含到我的 View 中，它就会像它应该做的那样工作。

我做错了什么？

在加载jQuery之前，您正在加载masonry-layout和imagesLoaded。你应该像这样在 jQuery 之后加载它:

try {
    window.Popper = require('popper.js').default;
    window.$ = window.jQuery = require('jquery');

    window.Masonry = require('masonry-layout');
    window.ImagesLoaded = require('imagesloaded');

    require('bootstrap');
} catch (e) {}

然后你可以像这样使用它:

new Masonry('.grid', {
    // options
});

此外，您还可以从 app.js 中删除它们。

注意

如果您确实希望能够像 $('.grid').masonry(...) 一样使用它，那么您需要安装 jquery-bridget:

npm install jquery-bridget

然后在引导文件中执行此操作:

var $ = require('jquery');
var jQueryBridget = require('jquery-bridget');
var Masonry = require('masonry-layout');

// make Masonry a jQuery plugin
jQueryBridget( 'masonry', Masonry, $ );

// now you can use $().masonry()
$('.grid').masonry({
  columnWidth: 80
});
