Рендеринг на стороне сервера Angular 6.1

0 голосов
/ 29 декабря 2018

Я работаю с Angular 6.1.0 и следую официальному документу по SSR здесь .

Проблема, с которой я сталкиваюсь, заключается в том, что при запуске команды:

npm run build:ssr && npm run serve:ssr

serve:ssr выдает мне кучу ошибок из файлов .spec.ts моего node_modules.

Я загрузил свой проект на GitHub here Поскольку я понятия не имею, что его нарушает.

PS: исходный код, предоставленный официальными документами, также ломается с теми же ошибками.Следовательно, если должно быть что-то с моим env

Консольный вывод: 

PS C:\Users\adity\Desktop\SSR_POC> npm run build:ssr

Итак, на основе одного из моих проектов я смог выяснить несколько проблем:

В массиве правил webpack.server.config.js у меня есть дополнительное правило: 

    {
            // Mark files inside `@angular/core` as using SystemJS style dynamic imports.
            // Removing this will cause deprecation warnings to appear.
            test: /(\\|\/)@angular(\\|\/)core(\\|\/).+\.js$/,
            parser: {system: true},
    },

Я полагаю, что это приводит к тому, что некоторые предупреждения, отправленные вами вокруг System.import, устарели.

В server.ts у меня есть 

const {AppServerModuleNgFactory, LAZY_MODULE_MAP} = require("./dist/server/main")

, которые не могут быть решены ./Ошибка main.bundle.

Кроме того, я думаю, что ваш файл tsconfig.server.json должен выглядеть следующим образом: 

{
  "extends": "./tsconfig.app.json",
  "compilerOptions": {
    "outDir": "../out-tsc/app-server",
    "baseUrl": "."
  },
  "angularCompilerOptions": {
    "entryModule": "app/app.server.module#AppServerModule"
  }
}

И, наконец, для устранения ошибок при наборе текста с помощью жасмина вам необходимо обновить машинопись до версии 2.9.х (npm update typescript) должен добиться цели.
