  3. fantasy-land

    Specification for interoperability of common algebraic structures in JavaScript

    Project mention: JavaScript's Missed Opportunity: Async/Await, Optional Chaining, and flatMap are the same thing | dev.to | 2025-02-19

    (This was one of the purposes of the Fantasy Land specification, to define common interfaces for generalized operations that could benefit from language-syntax-support.)

  4. spec

  5. fluent

    Fluent — planning, spec and documentation

    Project mention: Show HN: Open-source React library to translate apps without rewriting code | news.ycombinator.com | 2025-06-03

    I think modern Japanese is LTR, but besides that - I believe the project you worked in the past solves an important problem.

    Besides pluralization (and e.g. Arabic having 6 forms zero/one/two/few/many/other), turned out number internationalization and currency conversion are big next challenges the community wants to address next.

    > create ICU compliant JSON.

    I think this is an excellent idea. I have a feeling in the future we will need ICU v2.0, sort of, but unfortunately it's an extremely hard problem and the probability to fail is pretty high (looks like project fluent is not actively maintained anymore: https://github.com/projectfluent/fluent)

  6. graphql-schema

    GitHub’s GraphQL Schema with validation. Automatically updated.

  7. box-openapi

    OpenAPI 3.0 Specification for the Box APIs

  8. openapi-types.ts

    Generated TypeScript definitions based on GitHub's OpenAPI spec
