<title>HTML-over-WebSockets — David Larlet</title>
<meta name="description" content="But this wasn’t terribly easy for many developers to grok at first. I sure didn’t. And the benefits weren’t exactly clear either. After years (decades, even) of wrapping our heads around the HTTP request cycle, to which all server-handled features must conform, adopting this WebSocket tech layer required a lot of head scratching. As with many clever new technologies or protocols, we needed a higher-level abstraction that provided something really effective for getting a new feature in front of a user, fast.">

<p>En ce moment, ça me gratte justement bien la tête. Je me retrouve <a href="https://benhoyt.com/writings/the-small-web-is-beautiful/">davantage dans cette approche</a> (<a href="/david/cache/2021/862d065d924906f327f8a95e23659295/">cache</a>) et j’ai presque du plaisir à utiliser <a href="https://stimulus.hotwire.dev/">Stimulus</a>, ça semble être le niveau de structuration et de non-abstraction dont j’ai besoin. J’ai aussi essayé <a href="https://turbo.hotwire.dev/">Turbo</a> (Frames) mais je n’ai pas été assez loin pour voir les avantages décrits dans l’article (et c’est trop jeune pour mon niveau de confiance)&nbsp;: j’ai fini par recoder juste ce qu’il me fallait avec Stimulus.</p>
<p>J’apprécie le fait que ces ré-explorations donnent lieux à de nouvelles initiatives comme <a href="https://www.django-unicorn.com/">Django-Unicorn</a> ou <a href="https://sockpuppet.argpar.se/">Sockpuppet</a> pour ne citer que les déclinaisons dans l’écosystème Django. J’ai l’impression que c’est le compromis acceptable pour le vieux développeur que je suis&nbsp;: de la réactivité au niveau de l’interface pour les utilisateur·ices, de la logique et de la stabilité côté développement pour ma sénilité d’esprit.</p>
<p>Attention si vous partez sur des WebSockets, j’ai <a href="https://httptoolkit.tech/blog/http-wtf/">récemment appris</a> (<a href="/david/cache/2021/cbd2101777421fa7549472859210a69c/">cache</a>) que les restrictions de type <abbr title="Cross-Origin Resource Sharing">CORS</abbr> ne sont pas du tout respectées.</p>
<p>Note&nbsp;: je suis surpris qu’il n’y ait pas encore un projet intitulé <strong>RESTream</strong> dans le domaine 🙃🚎.</p>
