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 🙏

Uso

Primeiro, vamos importar o nosso pacote.

import * as NFA from 'nextjs-firebase-auth';

Agora vamos definir os tipos de usuários e o modelo do usuário.

interface User {
   id: string;
   name: string;
   email: string;
   phone: number;
   photoURL: string | null;
   createdAt: string;
}

type UserRole = 'user' | 'admin';

Feito isso podemos criar um contexto que irá retornar o nosso AuthProvider, passando para ele as propriedades necessárias.

interface ContextProps {
   children: React.ReactNode | JSX.Element;
}

if (!firebase.getApps().length) firebase.initializeApp(firebaseConfig);
const app = firebase.getApp();

export function AuthProvider(props: ContextProps) {
   return (
      // Estamos passando aqui os parâmetros de tipo
      <NFA.AuthProvider<UserRole, User>
         // Id único para cada projeto
         appId="unique-project-id"
         // Componente que será renderizado quando a autenticação estiver carregando
         loader={LoadingFullScreen}
         // Objeto com os tipos de usuários com os seus nomes personalizados
         roles={{
            user: 'Usuário',
            admin: 'Administrador',
         }}
         // Rotas que o fluxo de validação da autenticação será pulada
         disabledAuthRoutes={['/login']}
         // Rotas privadas da aplicação (Importante incluir todas)
         privateRoutes={['/dashboard*', '/panel*']}
         // Rotas públicas da aplicação (Importante incluir todas)
         publicRoutes={['/', '/login', '/register', '/forgot-password']}
         // Permissões para cada tipo de usuário
         permissions={{
            admin: {
               role: 'admin',
               mainRoute: '/dashboard',
               allowedRoutes: ['*'],
               restrictedRoutes: [],
            },
            user: {
               role: 'user',
               mainRoute: '/panel',
               allowedRoutes: ['/panel*'],
               restrictedRoutes: [],
            },
         }}
         // Firebase app
         firebaseApp={app}
      >
         {props.children}
      </NFA.AuthProvider>
   );
}

Agora só precisamos configurar e exportar o nosso hook useAuth passando para ele os nossos parâmetros de tipo.

export const useAuth = () => NFA.useNFA<UserRole, User>();

Pronto, o seu contexto de autenticação deve ter ficado mais ou menos assim.

import * as NFA from 'nextjs-firebase-auth';
import * as firebase from 'firebase/app';

import LoadingFullScreen from 'components/LoadingFullScreen';
import { firebaseConfig } from '../../firebaseConfig';

interface ContextProps {
   children: React.ReactNode | JSX.Element;
}

interface User {
   id: string;
   name: string;
   email: string;
   phone: number;
   photoURL: string | null;
   enterpriseId: string;
   createdAt: string;
}

type UserRole = 'user' | 'admin';

if (!firebase.getApps().length) firebase.initializeApp(firebaseConfig);
const app = firebase.getApp();

export function AuthProvider(props: ContextProps) {
   return (
      <NFA.AuthProvider<UserRole, User>
         appId="unique-project-id"
         loader={LoadingFullScreen}
         roles={{
            user: 'Usuário',
            admin: 'Administrador',
         }}
         disabledAuthRoutes={['/login']}
         permissions={{
            admin: {
               role: 'admin',
               mainRoute: '/dashboard',
               allowedRoutes: ['*'],
               restrictedRoutes: [],
            },
            user: {
               role: 'user',
               mainRoute: '/panel',
               allowedRoutes: ['/panel*'],
               restrictedRoutes: [],
            },
         }}
         privateRoutes={['/dashboard*', '/panel*']}
         publicRoutes={['/', '/login', '/register', '/forgot-password']}
         firebaseApp={app}
      >
         {props.children}
      </NFA.AuthProvider>
   );
}

export const useAuth = () => NFA.useNFA<UserRole, User>();
