JSer.info #683 - Parcel v2.12.0がリリースされました。 Parcel v2.12.0 Bunと同様の仕組みとして、Import Attributesを使ったmacroに対応しています。 JavaScript Macros in Bun | Bun Blog ブラウザ上で動作するREPLを公開、bundleにもLightning CSSを使うように変更されています。 その他にはメモリ使用量を52%改善、書き込みのパフォーマンスの改善なども行われています。 先週の記事で polyfill.io がFunnull CDN(方能CDN)を運営するFunnull(南京妙彩文化传播有限公司)に買収されたことをお伝えしました。 その後、FastlyやCloudflare(cdnjs)が polyfill.io の代用サービスとして、https://polyfill-fast
CDNのエッジで実行する系が面白い
先日の Next.js Conf で Vercel は Next.js の新しいバージョン「12」をリリースした。 興味深いのは、Vercel は同時にEdge Functionsというサービスを開始したことだ。 Edge Functions – Vercel 謳い文句のひとつに Push your functions to the edge とあるように、「エッジ」で実行される「関数」を提供するプラットフォームである。 ここで言うエッジとはなにかというと、Vercel は明言していないが CDN のエッジのことだ。 Vercel の例のように「CDN のエッジで実行する系」が増えている。例えば以下の 7 つだ。 Cloudflare Workers Fastly Compute@Edge AWS CloudFront Functions AWS Lambda@Edge Deno Depl
bundlejs - Online bundler + npm package size checker
When bundling packages that also export CSS and other external files, bundlejs.com now checks the gzip/brotli size of these external files, even though it won't output any code. Keep this in mind this isn't a bug, however, if it causes confusion I am willing to change this behaviour. Treeshaking is available, but not all CDNs support access to each packages package.json so there might be slight pa

Introducing Edge Handlers in Preview | Netlify
As adoption of the Jamstack model has become more widespread, so have the needs of a traditional CDN shifted. Today, content is expected to be fast, highly customizable, and up to date within a fraction of a second. Strictly static CDNs, which store static assets and serve them indistinguishably for every request, are insufficient to handle the more dynamic, personalized nature of modern content.
An Update on CDNJS
When you loaded this blog, a file was delivered to your browser called jquery-3.2.1.min.js. jQuery is a library which makes it easier to build websites, and was at one point included on as many as 74.1% of all websites. A full eighteen million sites include jQuery and other libraries using one of the most popular tools on Earth: CDNJS. Beginning about a month ago Cloudflare began to take a more ac
The British Airways Hack: JavaScript Weakness Pin-pointed Through Time-lining
A few years ago I predicted that JavaScript would soon be a dead language as it has fossilized itself and was just so clunky to use. How wrong could I have been, in that it now rules the roost in terms of making Web pages more dynamic. But it is now opening up holes on the Internet, and it is suspected that it was behind the British Airways hack. There was great speculation that the hack had been
