我需要一些帮助。
我想用Angular Universal渲染我的Angular应用程序。我使用ng generate universal my-app
(@ angular / cli @ 1.6.0)生成了我的服务器文件,它生成了所有必需的服务器文件(main.server.ts,tsconfig.server.ts,...)。我在我的根目录中创建了一个server.ts文件(代码与cli文档中的相同)和webpack.config.js文件(也是相同的)。构建过程完成没有错误,但是当我尝试在浏览器中打开页面时,我得到错误而没有别的(page)。当我查看网络选项卡时,我看到了network error。但是,如果我尝试打开localhost:4000 / index.html,索引文件将被提供/呈现。
注意server.ts中的console.log("does it get here");
,当我检查控制台时它会被注销。但索引不会呈现。
server.ts
// These are important and needed before anything else
import 'zone.js/dist/zone-node';
import 'reflect-metadata';
import { renderModuleFactory } from '@angular/platform-server';
import { enableProdMode } from '@angular/core';
import * as express from 'express';
import { join } from 'path';
import { readFileSync } from 'fs';
// Faster server renders w/ Prod mode (dev mode never needed)
enableProdMode();
// Express server
const app = express();
const PORT = process.env.PORT || 4000;
const DIST_FOLDER = join(process.cwd(), 'dist');
// Our index.html we'll use as our template
const template = readFileSync(join(DIST_FOLDER, 'browser', 'index.html')).toString();
// * NOTE :: leave this as require() since this file is built Dynamically from webpack
const { AppServerModuleNgFactory, LAZY_MODULE_MAP } = require('./dist/server/main.bundle');
const { provideModuleMap } = require('@nguniversal/module-map-ngfactory-loader');
app.engine('html', (_, options, callback) => {
renderModuleFactory(AppServerModuleNgFactory, {
// Our index.html
document: template,
url: options.req.url,
// DI so that we can get lazy-loading to work differently (since we need it to just instantly render it)
extraProviders: [
provideModuleMap(LAZY_MODULE_MAP)
]
}).then(html => {
callback(null, html);
});
});
app.set('view engine', 'html');
app.set('views', join(DIST_FOLDER, 'browser'));
// Server static files from /browser
app.get('*.*', express.static(join(DIST_FOLDER, 'browser')));
// All regular routes use the Universal engine
app.get('*', (req, res) => {
console.log("does it get here");
res.render(join(DIST_FOLDER, 'browser', 'index.html'), { req });
});
// Start up the Node server
app.listen(PORT, () => {
console.log(`Node server listening on http://localhost:${PORT}`);
});
我还下载了angular-universal-started,但它在那里工作,所以我做错了什么?有没有人遇到同样的错误?我真的很感激一些帮助:D
更新 我发现这是因为ngx-translate软件包。我认为这是因为服务器端呈现不支持http请求,翻译文件应该从文件系统中获取而不是http请求(我认为)。
