Question

env。 Ubuntu 16.04 节点：v10.15.1 npm：6.4.1

我新创建的Web应用程序中有两个页面，而html则更少。没有ajax调用。

这是我的package.json

{
  "name": "frontend",
  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e"
  },
  "private": true,
  "dependencies": {
    "@angular/animations": "~7.2.0",
    "@angular/common": "~7.2.0",
    "@angular/compiler": "~7.2.0",
    "@angular/core": "~7.2.0",
    "@angular/forms": "~7.2.0",
    "@angular/platform-browser": "~7.2.0",
    "@angular/platform-browser-dynamic": "~7.2.0",
    "@angular/router": "~7.2.0",
    "bootstrap": "^3.3.7",
    "core-js": "^2.5.4",
    "ngx-bootstrap": "^3.2.0",
    "rxjs": "~6.3.3",
    "tslib": "^1.9.0",
    "zone.js": "~0.8.26"
  },
  "devDependencies": {
    "@angular-devkit/build-angular": "~0.13.0",
    "@angular/cli": "~7.3.1",
    "@angular/compiler-cli": "~7.2.0",
    "@angular/language-service": "~7.2.0",
    "@types/node": "~8.9.4",
    "@types/jasmine": "~2.8.8",
    "@types/jasminewd2": "~2.0.3",
    "codelyzer": "~4.5.0",
    "jasmine-core": "~2.99.1",
    "jasmine-spec-reporter": "~4.2.1",
    "karma": "~3.1.1",
    "karma-chrome-launcher": "~2.2.0",
    "karma-coverage-istanbul-reporter": "~2.0.1",
    "karma-jasmine": "~1.1.2",
    "karma-jasmine-html-reporter": "^0.2.2",
    "protractor": "~5.4.0",
    "ts-node": "~7.0.0",
    "tslint": "~5.11.0",
    "typescript": "~3.2.2"
  }
}

在chrome调试中，我看不到任何延迟，所有负载都在2-3毫秒内。但实际上，刷新需要2-3至4秒。

这就是我定义路线的方式。

import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import {AppComponent} from './app.component';
import {RegisterForm1Component} from './components/register/register-form1.component';
import {MembershipComponent} from './domain/membership.component';

const routes: Routes = [
  { path: '', redirectTo: '/login', pathMatch: 'full' },
  { path: '', redirectTo: '/register', pathMatch: 'full' },
  { path: 'login', component: MembershipComponent },
  { path: 'register', component: RegisterForm1Component }
];

@NgModule({
  declarations: [],
  imports: [ RouterModule.forRoot(routes) ],
  exports: [ RouterModule ]
})
export class AppRoutingModule {


}

有什么主意吗？

我在您的配置中看不到任何错误。但是您可以提高应用程序的性能：

检查您始终使用Angular路由，而不是在每个新路由上完全重新加载您的应用程序。
```
Use `<a [routerLink]="[url]">` and `this.router.navigate([url]);`
```
您可以使用AOT编译来增加应用的脚本编写时间
您可以通过将应用拆分为多个块（延迟加载）并对其进行丑化来减小包的大小

刷新时角度7慢或更改路由
