GraphQLクライアントにurqlをおすすめしたい
GraphQLのクライアントといえばApollo Clientが使われることが多いと思いますが、urqlというクライアントをおすすめする記事です。 TL;DR urqlのドキュメントキャッシュはApolloみたいなキャッシュ管理が要らなくて楽だからおすすめ ドキュメントキャッシュは、Mutationの __typename を見て汚れたキャッシュを捨てる仕組み Mutationのあと refetchQueries やってるならそれはurqlが自動でやってることと同じ なぜurqlをおすすめするのか この記事ではurqlのドキュメントキャッシュというキャッシュを仕組みだけを紹介します。雑に言うと、Apolloの正規化されたキャッシュより多少効率は落ちるものの煩雑な正規化されたキャッシュの管理から解き放たれるというものです。Apolloのキャッシュの管理に疲れた人にめちゃくちゃおすすめですし、

How to Eliminate Render-Blocking Resources: a Deep Dive
You might be here because Lighthouse told you to "eliminate render-blocking resources". Render-blocking resources are a common hurdle to rendering your page faster. They impact your Web Vitals which now impact your SEO. Slow render times also frustrate your users and can cause them to abandon your page. I worked with one client to reduce their render-blocking resources and improved their site load

URLPattern brings routing to the web platform | Web Platform | Chrome for Developers
Published: July 22, 2021 Routing is a key piece of every web application.

Routing might be implemented in a number of ways: Server code that maps paths to files on a disk Logic in a single-page app that waits for changes to the current locati
