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 🙏

@ascencia/id-core

v0.1.0-rc.1

Published

Client OIDC d'Ascencia ID – agnostique de tout framework, zéro dépendance runtime.

Readme

@ascencia/id-core

Le client OAuth 2.1 / OIDC d'Ascencia ID. Navigateur et serveur, sans dépendance runtime.

Il porte le flux authorization_code avec PKCE S256, l'échange et le rafraîchissement des jetons, la découverte OIDC, et l'évaluation des permissions côté client.

bun add @ascencia/id-core
import { createClient } from '@ascencia/id-core';

const client = createClient({
  issuer: 'https://id.ascencia.re',
  clientId: 'asc_cid_…',
  redirectUri: 'https://mon-site.fr/callback',
});

// Aller à l'écran de connexion
const { url } = await client.buildAuthorizeUrl();
location.assign(url);

// Au retour
const tokens = await client.handleCallback(location.search);

Ce qu'il ne fait pas

Il ne vérifie pas les jetons : vérifier une signature demande de récupérer et de mettre en cache le JWKS, ce qui n'a de sens que côté serveur. C'est le rôle de @ascencia/id-server.

Il ne stocke rien de sensible par défaut : le code_verifier d'une transaction en cours vit dans sessionStorage, jamais le jeton de rafraîchissement. Pour un site avec un serveur, préférer le montage confidentiel — les jetons restent alors chez vous et le navigateur ne reçoit qu'un cookie.

TypeScript

Le paquet est publié en source TypeScript. Les bundlers modernes le transpilent sans rien faire ; avec Next.js, l'ajouter à transpilePackages :

// next.config.ts
transpilePackages: ['@ascencia/id-core'],
