The Day.js Dilemma: How Should We Handle OSS Maintainers Going MIA?
As web developers, we heavily rely OSS packages. One popular example is Day.js, a JS lib for parsing, validating, manipulating, and formatting dates. It's a widely-used alternative to Moment, with over 17mil weekly downloads on npm.
A critical bug was discovered in Day.js (see: https://github.com/iamkun/dayjs/pull/2118) causing incorrect date manipulation (add, subtract) when in UTC TZ. This could have severe implications for any project relying on Day.js for date-related functionality. However, the maintainer of the project appears to be unresponsive, leaving the bug unresolved and the future of the library uncertain.
This raises some important questions for our community:
- At what point should we consider a widely-used OSS project "abandoned" if the maintainer is unresponsive?
- Is forking the project the best solution, or should we first try to reach out to the maintainer through other channels?
- Are there established community guidelines around responsiveness expectations for widely-used OSS projects?
- What are successful examples of community-driven forks or maintenance after a maintainer stepped away?
I am very aware that many of these developers give their spare time for free for these projects, with little or no payment, and I am very thankful for all their work. This developer does get some money (a small amount?) through OpenCollective, and possibly also works for a company (in China?) that makes a UI library, which I think uses Day.js internally.

well, I haven't reviewed the code, I just checked package.json and I'll suggest you to ditch moment.js Even the creator recommends ditching it. dayjs is a fantastic alternative.

This Week In React-Native #137: Expo Code Elimination, Monorepo, Hermes, Chain React, EAS, Skia, Expo Router, VisionCamera, React-Native-Graph
📜 I made JSON.parse() 2x faster: Radek proposes to improve the performance of Hermes by using very fast C++ libs based on SIMD instructions. Interesting to read even if you don't use React-Native. Ongoing discussions on the Hermes PR.

I made JSON.parse() 2x faster
Thanks! There's a preliminary PR with a discussion here: https://github.com/facebook/hermes/pull/933 (and broader context here: https://github.com/facebook/hermes/issues/811 ). But we'll see if there's any interest on Hermes' side to merging it. They definitely want to improve the parser, but it's unclear to me if they want to take on the simdjson/simdutf dependencies.

Don't pay for painfully slow React Native iOS builds anymore.
💉 Building and injecting a JS bundle a basic concept: If the native code wasn’t changed, simply create JS bundle and inject it into the precompiled application. (You must take an extra step to convert a js file to bytecode if you use the Hermes js engine.)
