  • The Day.js Dilemma: How Should We Handle OSS Maintainers Going MIA?
    2 projects | news.ycombinator.com | 12 Apr 2024
    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.

  • JSR Is Not Another Package Manager
    2 projects | news.ycombinator.com | 25 Apr 2024
    Regular expressions are part of the language, so it's not so unreasonable that TypeScript should parse them and take their semantics into account. Indeed, TypeScript 5.5 will include [new support for syntax checking of regular expressions](https://github.com/microsoft/TypeScript/pull/55600), and presumably they'll eventually be able to solve the problem the GP highlighted on top of those foundations.
  • TypeScript Essentials: Distinguishing Types with Branding
    2 projects | news.ycombinator.com | 24 Apr 2024
    Dedicated syntax for creating unique subsets of a type that denote a particular refinement is a longstanding ask[2] - and very useful, we've experimented with implementations.[3]

    I don't think it has any relation to runtime type checking at all. It's refinement types, [4] or newtypes[5] depending on the details and how you shape it.

  • Smart Contract Programming Languages: sCrypt vs. Solidity
    2 projects | dev.to | 5 Apr 2024
    Learning Curve and Developer Tooling sCrypt is an embedded Domain Specific Language (eDSL) based on TypeScript. It is strictly a subset of TypeScript, so all sCrypt code is valid TypeScript. TypeScript is chosen as the host language because it provides an easy, familiar language (JavaScript), but with type safety. There’s an abundance of learning materials available for TypeScript and thus sCrypt, including online tutorials, courses, documentation, and community support. This makes it relatively easy for beginners to start learning. It also has a vast ecosystem with numerous libraries and frameworks (e.g., React, Angular, Vue) that can simplify development and integration with Web2 applications.
