javascript - 延迟加载的 vue-router 组件不适用于 SSR

Question

我有两个不同的 server.js 和 client.js 入口点。(我使用的是 vue-server-renderer 和 laravel-mix)-(我的 server.js 和 client.js 看起来与此处描述的完全一样 - spatie/laravel-server-side-rendering如果我进行静态导出 import Test from '../views/Test' 它会工作..

如果我尝试在不延迟加载的情况下导入路由，SSR 会起作用:

import Test from "../views/Test";

export const routes = [{
    path: '/my-route',
    name: "Test",  
    component: Test,
}]

但是如果我尝试延迟加载，它在 SSR 上会失败:

export const routes = [{
    path: '/my-route',
    name: "Test"
    component: () => import('../views/Test.vue'),
}]

Cannot find module './js/chunks/server/0.js?id=c3384f174123f0848451'

对于 () => import('../views/Home.vue)，client.js 有效，只有 server.js 无效。

我的server.js:

import renderVueComponentToString from 'vue-server-renderer/basic';
import app from './app';
import {router} from './router/index';

new Promise((resolve, reject) => {
    router.push(context.url);
    router.onReady(() => {
        resolve(app);
    }, reject);
})
    .then(app => {
        renderVueComponentToString(app, (err, res) => {
            if (err) throw new Error(err);

            dispatch(res);
        });
    });

完整的错误是:

The command "/usr/bin/node /home/vagrant/Code/project/storage/app/ssr/1228cfee3f79dc5949bd898950384e53.js" failed Exit Code: 1(General error)

Working directory: /home/vagrant/Code/project/public Output:

Error: Cannot find module './js/chunks/server/0.js?id=c3384f174123f0848451'

更新

我想我可能知道为什么会这样(我可能错了):

export const routes = [{
     path: '/', 
     name: "Home", 
     component: () => import('../views/Home')
}]

使用这段代码，我得到一个错误:

Error: Cannot find module './js/chunks/server/0.js?id=c3384f174123f0848451'

The command "/usr/bin/node /home/vagrant/Code/project/storage/app/ssr/717358e60bfd52035a1e58256cdfbba0.js" failed. Exit Code: 1(General error) Working directory: /home/vagrant/Code/project/public Output: ================ Error Output: ================ internal/modules/cjs/loader.js:628 throw err; ^ Error: Cannot find module './js/chunks/server/0.js?id=c3384f174123f0848451'

查看路径:在我的编译文件中(位于 public/js)我有这一行:

var chunk = require("./js/chunks/server/" + ({}[chunkId]||chunkId) + ".js?id=" + {"0":"c3384f174123f0848451"}[chunkId] + "");

这似乎是一个相对路径。但是该文件实际上是按照我在 config/ssr.php 中指定的方式运行的 - 'temp_path' => storage_path('app/ssr') - 所以它找不到路径。

但是，即使我将 temp_path 更改为 public_path() 以便它可以从 ./js/chunks/server/ 中找到 block >(即 public/js/chunks/server/0.js)，它仍然会抛出相同的错误。即使 SSR 的 temp_path 不同。

The command "/usr/bin/node /home/vagrant/Code/project/public/3560d8d101faa4bdef316054b14873cc.js" failed. Exit Code: 1(General error) Working directory: /home/vagrant/Code/project/public Output: ================ Error Output: ================ internal/modules/cjs/loader.js:628 throw err; ^ Error: Cannot find module './js/chunks/server/0.js?id=c3384f174123f0848451'

此外，如果我在 renderVueComponentToString() 中 console.log(_dirname) 它返回我 '/'

我解决了它，现在它只能在客户端使用 SSR 和代码拆分 - 如果您有任何更好的想法，我仍然洗耳恭听。

我用了spatie/laravel-server-side-rendering而且设置起来非常简单。

这是我的解决方案(以及我对 spatie/laravel-server-side-rendering 的更改):

我了解了如何将 bundle 与 charlesBochet's comment 分开，但是我使用了一个文件而不是 2x webpack.mix.js 文件。

• package.json

"scripts": {
    // concurrently is just for building them asynchronously 
    "dev-all": "concurrently \"npm --section=server run dev\" \"npm --section=client run dev\"  --kill-others-on-fail",

    // can also build them separately if you wish
    "dev-client": "npm --section=client run dev",
    "dev-server": "npm --section=server run dev"
     ...
}

• webpack.mix.js

if (process.env.npm_config_section === 'server') {
    mix.js('resources/js/app-server.js', 'public/js')
        .webpackConfig({
            target: 'node',

            // Prevent code-splitting for server-build
            plugins: [
                new webpack.optimize.LimitChunkCountPlugin({
                    maxChunks: 1,
                })
            ],
        })
        // merge manifest is a package for merging manifests,
        // otherwise they'll get overwritten by each other
        // https://github.com/kabbouchi/laravel-mix-merge-manifest
        .mergeManifest()
        .version();

} else if (process.env.npm_config_section === 'client') {
    mix.js('resources/js/app-client.js', 'public/js')
        .webpackConfig({
            target: 'web',
            output: {
                chunkFilename: 'js/chunks/[name].js?id=[chunkhash]',
                publicPath: '/',
            },
        })
        .mergeManifest()
        .version();

    // Only build css with the client build, server build only needs
    // the html and not the css
    mix.sass('resources/sass/app.scss', 'public/css')
} else {
    console.log(
        '\x1b[41m%s\x1b[0m',
        'Provide correct --section argument to build command: server, client'
    );
    throw new Error('Provide correct --section argument to build command!')
}

• app-server.js - 应该等待路由器准备就绪

new Promise((resolve, reject) => {
    router.push(context.url);
    router.onReady(() => {
        resolve(app);
    }, reject);
})
    .then(app => {
        renderVueComponentToString(app, (err, res) => {
            if (err) throw new Error(err);
            dispatch(res);
        });
    });

• 应用程序客户端.js

router.onReady(function() {
    app.$mount('#app');
})

• 最后，路由器文件代码拆分适用于 app-client.js

export const routes = [
{
    path: '/',
    name: "Home",
    component: () => import('../views/Home.vue')
},
