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 🙏

Librairie de gestion de configuration. Permet de centraliser et d'accéder facilement à la configuration d'une application.

🔧 Installation

yarn add @nappr/nappr-config

🚀 Utilisation

1. Configuration du Provider

Enveloppez votre application avec le ConfigProvider :

import { ConfigProvider } from '@nappr/nappr-config';

const appConfig = {
  api: {
    baseUrl: 'https://api.example.com',
    timeout: 5000,
  },
  features: {
    enableAnalytics: true,
    enableNotifications: false,
  },
};

function App() {
  return (
    <ConfigProvider appConfig={appConfig}>
      <YourApp />
    </ConfigProvider>
  );
}

2. Utilisation dans un composant React

Utilisez le hook useConfig dans vos composants :

import { useConfig } from '@nappr/nappr-config';

function MyComponent() {
  const apiUrl = useConfig<string>('api.baseUrl');
  const timeout = useConfig<number>('api.timeout');
  const enableAnalytics = useConfig<boolean>('features.enableAnalytics');

  return <div>API URL: {apiUrl}</div>;
}

3. Utilisation hors composant React

Utilisez le service statique ConfigService dans vos fichiers utilitaires, services, etc. :

import { ConfigService } from '@nappr/nappr-config';

// Dans un fichier utilitaire ou service
export function createApiClient() {
  const baseUrl = ConfigService.getConfigByName<string>('api.baseUrl');
  const timeout = ConfigService.getConfigByName<number>('api.timeout');

  return new ApiClient({ baseUrl, timeout });
}

📚 API Publique

useConfigByName

Hook React pour récupérer une valeur de configuration.

const layout = useConfigByName<LayoutConfigInterface>('layout');
// const baseUrl = useConfigByName<string>('api.baseUrl');

ConfigService.getConfigByName

Récupère une valeur de configuration par son nom.

const baseUrl = ConfigService.getConfigByName<string>('api.baseUrl');

ConfigService.isInitialized

Vérifie si le service a été initialisé.

const isInitialized = ConfigService.isInitialized();

💡 Exemples

Configuration complexe

const appConfig = {
  api: {
    baseUrl: 'https://api.example.com',
    timeout: 5000,
    retries: 3,
  },
  features: {
    enableAnalytics: true,
    enableNotifications: false,
    enableDarkMode: true,
  },
  ui: {
    theme: 'dark',
    language: 'fr',
    itemsPerPage: 20,
  },
};

Utilisation dans différents contextes

// Dans un composant React
function ApiComponent() {
  const baseUrl = useConfigByName<string>('api.baseUrl');
  const timeout = useConfigByName<number>('api.timeout');

  useEffect(() => {
    fetch(`${baseUrl}/data`, { timeout });
  }, [baseUrl, timeout]);

  return <div>Loading...</div>;
}

// Dans un service
import { ConfigService } from '@nappr/nappr-config';

export class ApiService {
  private baseUrl: string;
  private timeout: number;

  constructor() {
    this.baseUrl = ConfigService.getConfigByName<string>('api.baseUrl');
    this.timeout = ConfigService.getConfigByName<number>('api.timeout');
  }

  async fetchData() {
    // Utilisation de la configuration
  }
}

// Dans un utilitaire
import { ConfigService } from '@nappr/nappr-config';

export function getApiEndpoint(path: string): string {
  const baseUrl = ConfigService.getConfigByName<string>('api.baseUrl');
  return `${baseUrl}${path}`;
}

Tests

import { ConfigService } from '@nappr/nappr-config';

describe('MyComponent', () => {
  beforeEach(() => {
    ConfigService.initialize({
      api: { baseUrl: 'http://test-api.com' },
    });
  });

  afterEach(() => {
    ConfigService.reset();
  });
});

📝 Notes importantes

  1. Provider requis : Tous les composants utilisant useConfig doivent être enfants de ConfigProvider
  2. Initialisation : Le ConfigProvider initialise automatiquement le ConfigService
  3. Immutabilité : La configuration fournie via appConfig n'est pas modifiée par le module &. Chemin pointé : Utilisez la notation pointée pour accéder aux valeurs imbriquées (ex: "api.baseUrl")
