WebAssembly JSPI has a new API · V8
WebAssembly’s JavaScript Promise Integration (JSPI) API has a new API, available in Chrome release M126. We talk about what has changed, how to use it with Emscripten, and what is the roadmap for JSPI. JSPI is an API that allows WebAssembly applications that use sequential APIs to access Web APIs that are asynchronous. Many Web APIs are crafted in terms of JavaScript Promise objects: instead of im

Stage 1 (explanation) TC39 proposal champions: Daniel Ehrenberg, Yehuda Katz, Jatin Ramanathan, Shay Lewis, Kristen Hewell Garrett, Dominic Gannaway, Preston Sego, Milo M, Rob Eisenberg Original authors: Rob Eisenberg and Daniel Ehrenberg This document describes an early common direction for signals in JavaScript, similar to the Promises/A+ effort which preceded the Promises standardized by TC39 i
JavaScript Visualized - Promise Execution
Promises in JavaScript can seem a bit daunting at first, but understanding what's happening under the hood can make them much more approachable. In this blog post, we'll dive deep into some of the inner workings of promises and explore how they enable non-blocking asynchronous tasks in JavaScript. I'm still working on making this blog better on mobile devices, mobile browsers don't always render t
The Hidden Performance Cost of NodeJS and GraphQL
NodeJS and GraphQL are popular technologies for building web applications, but in my experience, they come with certain scaling and performance tradeoffs to be aware of. tl;dr: GraphQL's modular structure generally leads to code that instantiates excessive promises, which degrades request performance. Benchmarks show a 2-3x latency increase. Thanks for reading Software at Scale! Subscribe for free
