@ngx-utils/cookies
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.
Table of contents:
Prerequisites
This package depends on @angular v5.0.0
.
And if you want to manage cookies on server side and you're using express as server you need install:
npm i -S cookie-parser @nguniversal/module-map-ngfactory-loader
Getting started
Installation
Install @ngx-utils/cookies from npm:
npm install @ngx-utils/cookies --save
browser.module.ts
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 { }
server.module.ts
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 { }
Cookies options
You can preset cookies options:
BrowserCookiesModule.forRoot({
path: '/',
domain: 'your.domain',
expires: '01.01.2020',
secure: true,
httpOnly: true
})
...
ServerCookiesModule.forRoot({
path: '/',
domain: 'your.domain',
expires: '01.01.2020',
secure: true,
httpOnly: true
})
API
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 bykey
;getObject(key: string): { [key: string]: string } | string
get object value from cookies bykey
;getAll(): { [key: string]: string }
get all cookies ;remove(key: string, options?: CookiesOptions): void
remove cookie bykey
;removeAll(): void
remove all cookies;
Example of usage
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,
},
