解决Angular SSR的高TTFB(Time to First Byte)问题可以通过以下几个步骤实现:
// 在app.module.ts文件中注册Service Worker
import { NgModule } from '@angular/core';
import { ServiceWorkerModule } from '@angular/service-worker';
import { environment } from '../environments/environment';
@NgModule({
imports: [
ServiceWorkerModule.register('ngsw-worker.js', { enabled: environment.production })
],
// ...
})
export class AppModule { }
// 在服务器端渲染的组件中,使用异步方法获取数据
import { Component, OnInit } from '@angular/core';
import { DataService } from 'path/to/data.service';
@Component({
selector: 'app-example',
template: `
{{ data }}
`
})
export class ExampleComponent implements OnInit {
data: any;
constructor(private dataService: DataService) { }
ngOnInit() {
this.dataService.getData().subscribe((data) => {
this.data = data;
});
}
}
{
"projects": {
"your-project-name": {
// ...
"architect": {
"build": {
"options": {
// ...
"deployUrl": "https://your-cdn-url.com/assets/"
}
}
}
}
}
}
通过以上方法,可以有效减少Angular SSR的高TTFB问题,提升应用的性能和用户体验。
