Angular2-Token

About

Token based authentication service for Angular2 with multiple user support. Angular2-Token works best with the devise token auth gem for Rails.

Angular2-Token is currently in Alpha. Any contribution is much appreciated.

Live Demo

You can try out Angular2-Token here.

Installation

1. Install Angular2-Token via NPM with

   npm install angular2-token --save

2. Import and add Angular2TokenService to your main module. Angular2TokenService depends on HttpModule and RouterModule, so make sure you imported them too.

   import { HttpModule } from '@angular/http';
   import { RouterModule } from '@angular/router';
   
   import { Angular2TokenService } from 'angular2-token';
   
   @NgModule({
       imports: [
           BrowserModule,
           HttpModule,
           RouterModule
       ],
       declarations: [ AppComponent ],
       providers:    [ Angular2TokenService ],
       bootstrap:    [ AppComponent ]
   })

3. Inject Angular2TokenService into your main component and call .init().

   constructor(private _tokenService: Angular2TokenService) {
       this._tokenService.init();
   }

4. If you are using CORS in your Rails API make sure that Access-Control-Expose-Headers includes access-token, expiry, token-type, uid, and client. For the rack-cors gem this can be done by adding the following to its config. More information can be found here

   :expose  => ['access-token', 'expiry', 'token-type', 'uid', 'client']

Configuration

Configuration options can be passed as Angular2TokenOptions via .init().

Default Configuration

constructor(private _tokenService: Angular2TokenService) {
    this._tokenService.init({
        apiPath:                    null,
        signInPath:                 'auth/sign_in',
        signOutPath:                'auth/sign_out',
        validateTokenPath:          'auth/validate_token',

        registerAccountPath:        'auth',
        deleteAccountPath:          'auth',
        registerAccountCallback:    window.location.href,

        updatePasswordPath:         'auth',
        resetPasswordPath:          'auth/password',
        resetPasswordCallback:      window.location.href,

        userTypes:                  null
    });
}

Configuration Options

• apiPath?: string - Sets base path all operations are based on
• signInPath?: string - Sets path for sign in
• signOutPath?: string - Sets path for sign out
• validateTokenPath?: string - Sets path for token validation
• registerAccountPath?: string - Sets path for account registration
• deleteAccountPath?: string - Sets path for account deletion
• registerAccountCallback?: string - Sets the path user are redirected to after email confirmation for registration
• updatePasswordPath?: string - Sets path for password update
• resetPasswordPath?: string - Sets path for password reset
• resetPasswordCallback?: string - Sets the path user are redirected to after email confirmation for password reset
• userTypes?: UserTypes[] - Allows the configuration of multiple user types (see Multiple User Types)

Further information on paths/routes can be found at devise token auth

Service Methods

Once initialized Angular2TokenService offers methods for session management.

.signIn()

The signIn method is used to sign in the user with email address and password. The optional parameter type specifies the name of UserType used for this session.

signIn(email: string, password: string, userType?: string): Observable<Response>

Example:

this._tokenService.signIn(
    'example@example.org',
    'secretPassword'
).subscribe(
    res =>      console.log(res),
    error =>    console.log(error)
);

.signOut()

The signOut method destroys session and session storage.

signOut(): Observable<Response>

Example:

this._tokenService.signOut().subscribe(
    res =>      console.log(res),
    error =>    console.log(error)
);

.registerAccount()

Sends a new user registration request to the Server.

registerAccount(email: string, password: string, passwordConfirmation: string, userType?: string): Observable<Response>

Example:

this._tokenService.registerAccount(
    'example@example.org',
    'secretPassword',
    'secretPassword'
).subscribe(
    res =>      console.log(res),
    error =>    console.log(error)
);

.deleteAccount()

Deletes the account for the signed in user.

deleteAccount(): Observable<Response>

Example:

this._tokenService.deleteAccount().subscribe(
    res =>      console.log(res),
    error =>    console.log(error)
);

.validateToken()

Validates the current token with the server.

validateToken(): Observable<Response>

Example:

this._tokenService.validateToken().subscribe(
    res =>      console.log(res),
    error =>    console.log(error)
);

.updatePassword()

Updates the password for the logged in user.

updatePassword(password: string, passwordConfirmation: string, currentPassword?: string, userType?: string): Observable<Response>

Example:

this._tokenService.updatePassword(
    'newPassword',
    'newPassword',
    'oldPassword'
).subscribe(
    res =>      console.log(res),
    error =>    console.log(error)
);

.resetPassword()

Request a password reset from the server.

resetPassword(email: string, userType?: string): Observable<Response>

Example:

this._tokenService.updatePassword(
    'example@example.org',
).subscribe(
    res =>      console.log(res),
    error =>    console.log(error)
);

HTTP Service Wrapper

Angular2TokenService wraps all standard Angular2 Http Service calls for authentication and token processing.

• get(path: string, requestOptions?: RequestOptions): Observable<Response>
• post(path: string, data: any, requestOptions?: RequestOptions): Observable<Response>
• put(path: string, data: any, requestOptions?: RequestOptions): Observable<Response>
• delete(path: string, requestOptions?: RequestOptions): Observable<Response>
• patch(path: string, data: any, requestOptions?: RequestOptions): Observable<Response>

Example:

this._tokenService.get('my-resource/1').map(res => res.json()).subscribe(
    res =>      console.log(res),
    error =>    console.log(error)
);

Multiple User Types

An array of UserType can be passed in Angular2TokenOptions during init(). The user type is selected during sign in and persists until sign out. .currentUser returns the currently logged in user.

Example:

this._tokenService.init({
    userTypes: [
        { name: 'ADMIN', path: 'admin' },
        { name: 'USER', path: 'user' }
    ]
});

this._tokenService.signIn(
    'example@example.com',
    'secretPassword',
    'ADMIN'
)

this._tokenService.currentUser; // ADMIN

Route Guards

Angular2-Token implements the CanActivate interface, so it can directly be used as a route guard. It currently does not distinguish between user types.

Example:

const routerConfig: Routes = [
    { 
        path: '', 
        component: PublicComponent 
    }, {
        path: 'restricted', 
        component: RestrictedComponent, 
        canActivate: [Angular2TokenService] 
    }
];
