Deno in 2023; Turborepo 1.12; Promise.withResolvers; import attributes; Christopher “vjeux” Chedeau

“In 2023, Deno shifted into high gear with respect to Node/npm compatibility and performance work, while continuing to move towards our goal of radically simplifying web development.”

The blog post starts with an overview that gives a good impression of the status quo of Deno.

• Colors in task logs: Colors from original shell logs used by default
• Errors overhaul: Improved error messages for misconfigurations
• Improved inputs ergonomics: Use Turborepo’s defaults with your input customizations
• Telemetry: Help us focus on what matters most to Turborepo users
• “We’re also done cleaning up our migration to Rust in this release by removing the --go-fallback flag and shrinking the turbo binary by 58% compared to 1.11.”

const { promise, resolve, reject } = Promise.withResolvers();

“Import attributes” (keyword with ) replace the previous ECMAScript proposal “import assertions” (keyword assert):

import json from './foo.json' with { type: 'json' };

“The most important difference is that import assertions had assert-only semantics, while import attributes has more relaxed semantics. Assert-only semantics means that the additional information has no effect on how a module is loaded, only on whether it is loaded.”

Problem: On the web, how you request a resource affects what you receive.
