Decorator-powered JWT handling library for Grappa and Angular 9+, plus RxJs 6+.
Last version | Angular Versions | Node | Typescript |
---|---|---|---|
1.0.0 | 9+ up to 15 (included) | 14 | 4.6 |
npm i --save @elemental-concept/grappa-jwt
Add GrappaJwtModule
to your main AppModule
to imports section.
@NgModule({
declarations: [ ... ],
imports: [
...,
GrappaJwtModule
],
providers: [ ],
bootstrap: [ ... ]
})
export class AppModule {
}
Grappa JWT provide a easy and automatic way of using JWT in your HttpClient.
To be able to use is you need to pass the token to the SessionManagerService
:
@Injectable()
export class JWTService {
constructor(sessionManagerService: SessionManagerService) {
}
login = () =>
this.someService
.login(request)
.subscribe(
response => !!response.token
? this.authSuccess(response)
: this.authError(),
() => this.authError());
private authSuccess(response: Response) {
this.sessionManagerService.token = `Bearer ${ response.token }`;
// do somehting
}
private authError() {
// error handling
}
}
You can use GrappaJwt with Grappa to have the full potential:
@Injectable()
@RestClient('http://example.com/api/')
@Authenticate()
export class UserService {
@GET('/users')
list: () => Observable<User[]>;
@GET('/users/{0}')
find: (id: number) => Observable<User>;
@POST('/users')
create: (user: User) => Observable<User>;
@PUT('/users/{0}')
update: (id: number, user: User) => Observable<User>;
}
if you want somehthing
@Injectable()
@RestClient('http://example.com/api/')
@Authenticate()
export class UserService {
constructor(sessionManagerService: SessionManagerService, router: Router) { }
@GET('/users')
list: () => Observable<User[]>;
@GET('/users/{0}')
find: (id: number) => Observable<User>;
@POST('/users')
create: (user: User) => Observable<User>;
@PUT('/users/{0}')
update: (id: number, user: User) => Observable<User>;
@AfterRequest()
expirationFilter(observable: Observable<any>) {
return observable.pipe(catchError(e => this.deauthorise(e)));
}
private deauthorise(e) {
if (e.status === 401 || e.status === 403) {
this.sessionManagerService.clear();
this.router.navigate([ '' ]).then();
}
return throwError(e);
}
}
by default GrappaJwt will use window.sessionStorage
, but you can use it with other storage. The Ionic Storage is a good example:
You first need to add a new PersistenceManager
using the Ionic Storage.
Remeber to user GRAPPA-JWT
as key.
export class PersistenceManager {
constructor(private readonly storage: Storage) { }
put(value: string) {
return this.storage.set('GRAPPA-JWT', value);
}
get() {
return this.storage.get('GRAPPA-JWT');
}
remove() {
this.storage.remove('GRAPPA-JWT');
}
}
Then you have to create a factory to create a GrappaAuthConfigToken
export function grappaConfigFactory(storage: Storage) {
return {
persistence: new PersistenceManager(storage)
};
}
Finally, provide the GrappaAuthConfigToken
using the grappaConfigFactory
you created, passing Storage
into the dependencies:
@NgModule({
declarations: [ AppComponent ],
imports: [
...,
IonicStorageModule.forRoot(),
GrappaAuthModule,
GrappaModule,
],
providers: [
{
provide: GrappaAuthConfigToken,
useFactory: grappaConfigFactory,
deps:[ Storage ]
}
],
bootstrap: [ AppComponent ]
})
export class AppModule { }
