Manage your cookies on client and server side (Angular Universal)
Example in @ngx-utils/universal-starter shows the way in which CookiesService is used to get access token from cookies on client and server side, and then set Authorization headers for all HTTP requests.
This package depends on @angular v9.0.0.
Install @ngx-utils/cookies from npm:
npm install @ngx-utils/cookies --save
Add BrowserCookiesModule to your browser module:
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { BrowserCookiesModule } from '@ngx-utils/cookies/browser';
...
import { AppModule } from './app/app.module';
import { AppComponent } from './app/app.component';
...
@NgModule({
imports: [
BrowserModule.withServerTransition({appId: 'your-app-id'}),
BrowserCookiesModule.forRoot(),
AppModule
...
],
bootstrap: [AppComponent]
})
export class BrowserAppModule { }Add ServerCookiesModule to your server module:
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ServerModule } from '@angular/platform-server';
import { ServerCookiesModule } from '@ngx-utils/cookies/server';
...
import { AppModule } from './app/app.module';
import { AppComponent } from './app/app.component';
...
@NgModule({
imports: [
BrowserModule.withServerTransition({ appId: 'your-app-id' }),
ServerModule,
ServerCookiesModule.forRoot(),
AppModule
...
],
bootstrap: [AppComponent]
})
export class ServerAppModule { }You can preset cookies options:
BrowserCookiesModule.forRoot({
path: "https://github.com/",
domain: 'your.domain',
expires: '01.01.2020',
secure: true,
httpOnly: true
})
...
ServerCookiesModule.forRoot({
path: "https://github.com/",
domain: 'your.domain',
expires: '01.01.2020',
secure: true,
httpOnly: true
})CookieService has following methods:
put(key: string, value: string, options?: CookiesOptions): void put some value to cookies;putObject(key: string, value: Object, options?: CookiesOptions): void put object value to cookies;get(key: string): string get some value from cookies by key;getObject(key: string): { [key: string]: string } | string get object value from cookies by key;getAll(): { [key: string]: string } get all cookies ;remove(key: string, options?: CookiesOptions): void remove cookie by key;removeAll(): void remove all cookies;
If you’re using express as server then add following code to your server.ts:
import { renderModuleFactory } from "@angular/platform-server";
import { provideModuleMap } from "@nguniversal/module-map-ngfactory-loader";
import * as cookieParser from "cookie-parser";
app.use(cookieParser("Your private token"));
app.engine("html", (_, options, callback) => {
renderModuleFactory(AppServerModuleNgFactory, {
document: template,
url: options.req.url,
extraProviders: [
provideModuleMap(LAZY_MODULE_MAP),
{
provide: "REQUEST",
useValue: options.req
},
{
provide: "RESPONSE",
useValue: options.req.res
}
]
}).then(html => {
callback(null, html);
});
});Then just import CookiesService from @ngx-utils/cookies and use it:
import { Component, OnInit } from "@angular/core";
import { CookiesService } from "@ngx-utils/cookies";
@Component({
selector: "app-root",
templateUrl: "./app.component.html",
styleUrls: ["./app.component.scss"]
})
export class AppComponent implements OnInit {
constructor(private cookies: CookiesService) {}
ngOnInit() {
this.cookies.put("some_cookie", "some_cookie");
this.cookies.put("http_only_cookie", "http_only_cookie", {
httpOnly: true
});
console.log(this.cookies.get("some_cookie"), " => some_cookie");
console.log(this.cookies.get("http_only_cookie"), " => undefined");
console.log(this.cookies.getAll());
}
}If you’re using another framework you need to overrride ServerCookiesService.
For example for koa you need add following code to your server:
app.use(async (ctx: Context) => {
ctx.body = await renderModuleFactory(AppServerModuleNgFactory, {
document: template,
url: ctx.req.url,
extraProviders: [
provideModuleMap(LAZY_MODULE_MAP),
{
provide: "KOA_CONTEXT",
useValue: ctx
}
]
});
});Then create server-cookies.service.ts:
import { Context } from "koa";
import { Inject, Injectable } from "@angular/core";
import {
CookiesService,
CookiesOptionsService,
CookiesOptions
} from "@ngx-utils/cookies";
@Injectable()
export class ServerCookiesService extends CookiesService {
private newCookies: { [name: string]: string | undefined } = {};
constructor(
cookiesOptions: CookiesOptionsService,
@Inject("KOA_CONTEXT") private ctx: Context
) {
super(cookiesOptions);
}
get(key: string): string {
return this.newCookies[key] || this.ctx.cookies.get(key);
}
protected cookiesReader() {
return {};
}
protected cookiesWriter(): (
name: string,
value: string | undefined,
options?: CookiesOptions
) => void {
return (name: string, value: string | undefined, options?: any) => {
this.newCookies[name] = value;
this.ctx.cookies.set(name, value, { httpOnly: false, ...options });
};
}
}And add server-cookies.service.ts to app.server.module.ts:
{
provide: CookiesService,
useClass: ServerCookiesService,
