在 next.js 中使用 Owl Carousel 2 并做出反应

Question

I want to use jQuery owl carousel with my next js react app. I dont want to use npm package react-owl-carousel only owl-carousel and jquery plugin.

I use lazy load with next.js dynamic and put the following code in my Webpack config:

import dynamic from 'next/dynamic';
const Slider = dynamic(() => import('...'), {
  ssr: false,
});

Webpack config:

config.plugins.push(new webpack.ProvidePlugin({
  $: 'jquery',
  jQuery: 'jquery',
  'window.jQuery': 'jquery',
}));

Slider component:

import 'owl.carousel';
import 'owl.carousel/dist/assets/owl.carousel.css';

When I use $('element').owlCarousel(...) , I got the following error:

TypeError: this.owl.owlCarousel is not a function

Answer 1

after checking the bundle file i find that webpack pass another jQuery instance to owl.carousel file

here is webpack bundle code

__webpack_require__(/*! jquery */ "../../node_modules/owl.carousel/node_modules/jquery/dist/jquery.js")

as you can see jQuery pass to plugin from node_modules/owl.carousel/node_modules/jquery/dist/jquery.js instead of node_modules/jquery/dist/jquery.js

i fixed issue by deleting node_modules/owl.carousel/node_modules

after that webpack pass node_modules/jquery/dist/jquery.js as jquery instance

1. Inject global window via jQuery and webpack inside next.config.js file at the root of your next.js project

    module.exports = { webpack: (config, { buildId, dev, isServer, defaultLoaders, webpack }) => { // Note: we provide webpack above so you should not `require` it // Perform customizations to webpack config config.plugins.push( new webpack.ProvidePlugin({ $: "jquery", jQuery: "jquery", "window.jQuery": "jquery" }) ); // Important: return the modified config return config; }

2. Slider component which uses react-owl-carousel component

    import OwlCarousel from "react-owl-carousel"; export default function MySlider({ sliders }) { return ( <section> <OwlCarousel loop={true} items={1} responsiveRefreshRate={0} autoplay={true} autoplayTimeout={7000} autoplayHoverPause={true} nav={true} navText={[ "<i class='icon-arrow-prev'></i>", "<i class='icon-arrow-next'></i>" ]} dots={false} margin={20} > <div class="item"></div> <div class="item"></div> </OwlCarousel> </section> ); }

3. Import the component and for use onto your parent component. Kindly note you MUST use the ssr:false option. Next.js documentation recommends it

   const MySlider = dynamic( () => import("./Myslider"), // No need for SSR, when the module includes a library that only works in the // browser. { ssr: false } );

Happy codding.

In next.config.js:

const webpack = require('webpack');
module.exports = {
webpack: (config, { buildId, dev, isServer, defaultLoaders, webpack }) => {
config.plugins.push(new webpack.ProvidePlugin({
        $: 'jquery',
        jQuery: 'jquery',
        'window.jQuery': 'jquery'
    }))
return config;
}}

In your component:

import "owl.carousel/dist/assets/owl.carousel.css";
import "owl.carousel/dist/assets/owl.theme.default.css";
const OwlCarousel = dynamic(import("react-owl-carousel"), {ssr: false});
