Introducing the JSR open governance board

deno.com github.com/ry @lcasdev@mastodon.social github.com/crowlKats @deno_land@fosstodon.org

“Although the Deno team built JSR, the open source registry is intended not to be a Deno project, but rather an openly governed community service that benefits the greater JavaScript and TypeScript ecosystem. Today marks a big shift towards that vision, as we’re thrilled to announce that JSR now has an independent governing board of directors with a governance charter.”

“In this blog post, we’ll introduce the new board members, share the governance charter, and provide ways to get involved and stay in the loop.”

Moving on to ESM-only npm packages

antfu.me @antfu@webtoo.ls

“Three years ago, I wrote a post about shipping ESM & CJS in a single package, advocating for dual CJS/ESM formats to ease user migration and trying to make the best of both worlds. Back then, I didn’t fully agree with aggressively shipping ESM-only, as I considered the ecosystem wasn’t ready, especially since the push was mostly from low-level libraries. Over time, as tools and the ecosystem have evolved, my perspective has gradually shifted towards more and more on adopting ESM-only.”

There are a lot of ways to break up long tasks in JavaScript

macarthur.me github.com/alexmacarthur

“It’s very common to intentionally break up long, expensive tasks over multiple ticks of the event loop. But there are sure are a lot of approaches to choose from. Let’s explore them.”
