Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

About the library

Ronas IT Angular Common working with cookies. One of the main advantages of this approach is that cookies can be HTTP-only. It makes them read-protected on the client side, that improves safety against any Cross-site scripting (XSS) attacks. Cookie-based authentication allows using this services in Server-Side Rendering (SSR) applications.

Getting Started

Installation

Install Ronas IT Angular Common:

npm i @ronas-it/angular-common --save

Usage

ApiModule

  1. Add ApiModule to AppModule imports:
import { ApiModule } from '@ronas-it/angular-common';
import { configuration } from '@configuration';

@NgModule({
  imports: [
    ApiModule.forRoot({
      apiUrl: configuration.api.url
    }),
    ...
  ],
  ...
})
export class AppModule { }
  1. Inject ApiService and use it:
import { ApiService } from '@ronas-it/angular-common';
import { Injectable } from '@angular/core';

@Injectable()
export class ProductService {
  constructor(
    private apiService: ApiService
  ) { }

  public delete(id: number): Observable<void> {
    return this.apiService.delete(`/products/${id}`);
  }

  ...
}

CookieModule

  1. Add CookieModule to AppModule imports:
import { CookieModule } from '@ronas-it/angular-common';

@NgModule({
  imports: [
    CookieModule.forRoot({
      defaultOptions: { path: '/', /* other cookie options ... */ }
    }),
    ...
  ],
  ...
})
export class AppModule { }
  1. Inject CookieService and use it:
import { BehaviorSubject, Subject } from 'rxjs';
import { CookieService } from '@ronas-it/angular-common';
import { Injectable } from '@angular/core';

@Injectable()
export class CookiePopupFacade {
  private isCookiesAccepted$: Subject<boolean>;

  constructor(
    private cookieService: CookieService
  ) { 
    this.isCookiesAccepted$ = new BehaviorSubject(this.cookieService.get('isCookiesAccepted') === 'true');
  }

  public acceptCookies(): void {
    this.isCookiesAccepted$.next(true);

    this.cookieService.put('isCookiesAccepted', 'true', { maxAge: 4e10 });
  }

  ...
}
  1. (SSR Only) Add providers for REQUEST and RESPONSE injection tokens from @nguniversal/express-engine/tokens in server.ts:
server.get('*', (req, res) => {
  res.render(indexHtml, {
    req,
    res,
    providers: [
      {
        provide: APP_BASE_HREF,
        useValue: req.baseUrl
      },
      {
        provide: REQUEST,
        useValue: req
      },
      {
        provide: RESPONSE,
        useValue: res
      }
    ]
  });
});
  1. (SSR Only) Set requestToken and responseToken parameters in the CookieModule config:
import { CookieModule } from '@ronas-it/angular-common';
import { REQUEST, RESPONSE } from '@nguniversal/express-engine/tokens';

@NgModule({
  imports: [
    CookieModule.forRoot({
      defaultOptions: { /* ... */ },
      requestToken: REQUEST,
      responseToken: RESPONSE
    }),
    ...
  ],
  ...
})
export class AppModule { }

UserModule

Note: This module depends on ApiModule and AuthModule. Please make sure to install them prior to installing this module.

  1. Create a User model and extend it from AbstractUser:
import { AbstractUser } from '@ronas-it/angular-common';
import { Expose } from 'class-transformer';

export class User extends AbstractUser {
  @Expose({ groups: ['main'] })
  public id: number;

  @Expose({ groups: ['main'] })
  public name: string;

  @Expose({ groups: ['main'] })
  public email: string;
}
  1. Create a UserService and extend it from CommonUserService:
import { UserService as CommonUserService } from '@ronas-it/angular-common';

@Injectable()
export class UserService extends CommonUserService<User> {
  /* Define custom methods or override existing methods here. */
}
  1. Create a UserModule and add CommonUserModule to imports:
import { NgModule } from '@angular/core';
import { User } from './models';
import { UserModule as CommonUserModule } from '@ronas-it/angular-common';
import { UserService } from './user.service';

@NgModule({
  imports: [
    CommonUserModule.forRoot({
      userModel: User,
      userService: UserService
    }),
    ...
  ],
  ...
})
export class UserModule { }
  1. Inject UserService and use it:
import { Action } from '@ngrx/store';
import { Actions, createEffect, ofType } from '@ngrx/effects';
import { AuthService } from '@shared/auth';
import { catchError, filter, mergeMap, switchMap, withLatestFrom } from 'rxjs/operators';
import { HttpErrorResponse } from '@angular/common/http';
import { Injectable } from '@angular/core';
import { Observable, of } from 'rxjs';
import { User } from '../models';
import { userActions } from './actions';
import { UserService } from '../user.service';

@Injectable()
export class UserEffects {
  public refreshProfile$: Observable<Action> = createEffect(
    () => this.actions$.pipe(
      ofType(userActions.refreshProfile),
      withLatestFrom(this.authService.isAuthenticated$),
      filter(([_, isAuthenticated]) => isAuthenticated),
      switchMap(() => {
        return this.userService.refreshProfile()
          .pipe(
            mergeMap((user: User) => [
              userActions.updateProfile({ profile: user }),
              userActions.refreshProfileSuccess()
            ]),
            catchError((response: HttpErrorResponse) => of(userActions.refreshProfileFailure({ response })))
          );
      })
    )
  );

  constructor(
    private actions$: Actions,
    private authService: AuthService,
    private userService: UserService
  ) { }
}

AuthModule

Note: This module depends on ApiModule, CookieModule and UserModule. Please make sure to install them prior to installing this module.

  1. Create an AuthService and extend it from CommonAuthService:
import { AuthService as CommonAuthService } from '@ronas-it/angular-common';
import { Injectable } from '@angular/core';
import { User } from '@shared/user';

@Injectable()
export class AuthService extends CommonAuthService<User> {
  /* Define custom methods or override existing methods here. */
}
  1. Create an AuthModule and add CommonAuthModule to imports:
import { AuthModule as CommonAuthModule } from '@ronas-it/angular-common';
import { AuthService } from './auth.service';
import { configuration } from '@configuration';
import { NgModule } from '@angular/core';

@NgModule({
  imports: [
    CommonAuthModule.forRoot({
      unauthorizedRoutes: configuration.api.unauthorized_routes,
      authService: AuthService,

      // Optionally, you can pass `unauthenticatedRoute` parameter that
      // specifies the route to redirect to after logout or when a user is
      // not authenticated to view some page. By default it is set to `/login`.
      unauthenticatedRoute: '/'
    }),
    ...
  ],
  ...
})
export class AuthModule { }
  1. Inject AuthService and use it:
import { Action } from '@ngrx/store';

import { Injectable } from '@angular/core';
import { Observable, of } from 'rxjs';

@Injectable()
export class AuthEffects {
  public authorize$: Observable<Action> = createEffect(
    () => this.actions$.pipe(
      ofType(authActions.authorize),
      exhaustMap((action) => {
        return this.authService
          .authorize(action.credentials)
          .pipe(
            map((response) => authActions.authSuccess({ response })),
            catchError((response) => of(authActions.authFailure({ response })))
          );
      })
    )
  );
