    Substrate

    Substrate

    An Open-source Framework for Human Understanding, Meaning, Progress

    Substrate is an open-source framework focused on human understanding, meaning, and progress. It aims to surface and structure conceptual objects—ideas, problems, beliefs, models, frames, goals, arguments, sources—to make them more transparent, discussable and actionable. The goal is to enable communities to collectively build and maintain a repository of these objects so that complex systems of meaning and progress can be mapped, analyzed and improved. It is relatively ambitious in scope—seeking to help humanity organise knowledge and action around matters that matter rather than purely technical concerns. ...

    Valtio

    Valtio

    Valtio makes proxy-state simple for React and Vanilla

    Valtio is a lightweight, proxy-based state management library for JavaScript and TypeScript, designed to simplify reactive state handling in both React and vanilla environments. It allows you to manage mutable state through normal JavaScript objects, while providing React hooks (useSnapshot) and subscription utilities to create optimized component re-renders and state observation. It uses ECMAScript Proxies and supports deep state tracking, making state mutation intuitive and powerful without sacrificing performance or compatibility with React's concurrency model.

    match-sorter

    match-sorter

    Simple, expected, and deterministic best-match sorting

    ...It is designed to produce “simple, expected, and deterministic” results so users see intuitive matches instead of opaque fuzzy scores. The core API accepts arrays of strings or objects and returns a filtered, ranked list, making it a natural fit for search boxes, autocomplete components, and table filtering. It supports a variety of advanced options, such as specifying which object keys to search, controlling the matching threshold, and customizing the base sorting logic. The library includes recipes and examples that show how to handle different naming conventions like PascalCase, camelCase, snake_case, and kebab-case by normalizing separators. ...

    OSRS .json Hiscores

    OSRS .json Hiscores

    The Oldschool Runescape API wrapper that does more

    OSRS .json Hiscores is a server-side API wrapper designed to transform Old School RuneScape hiscores data into structured and developer-friendly JSON objects, addressing limitations in the official API’s output formats. The official API typically returns CSV or basic arrays, which can be difficult to work with, so this project restructures the data into meaningful objects that include player stats, rankings, and inferred metadata. It also adds additional logic to determine player game modes, including historical transitions such as de-ironing or hardcore status changes. ...

    Functions Framework for Node.js

    Functions Framework for Node.js

    FaaS (Function as a service) framework for writing portable Node.js

    ...The framework supports multiple function signature types, including HTTP-based functions and event-driven functions, and automatically parses incoming request payloads into structured objects that can be easily consumed by application logic. It also includes support for CloudEvents, allowing seamless integration with event-driven architectures and modern cloud-native systems. By abstracting the underlying infrastructure, the framework enables developers to focus on business logic while maintaining compatibility with platforms like Cloud Run and Cloud Functions.

    ...You can return a promise in the controller, and it will wait until promise resolved and return promise result in a response body. You can use framework's request and response objects directly. If you want to handle the response by yourself, just make sure you return the response object itself from the action. If you have, or if you want to create and configure express app separately, you can use useExpressServer instead of createExpressServer function. Express uses express-session / Koa uses koa-session or koa-generic-session to handle session.

Parameters that require date types accept YYYY-MM-DD formatted date-strings, JavaScript date objects, calendar objects and UTC timestamps. Calendars can be localized by adding custom locales to LocaleConfig object. Keep in mind that different marking types are not compatible. You can use just one marking style for a calendar. If you need custom functionality not supported by current day component implementations you can pass your own custom day component to the calendar.

    The best way to create REST APIs

    ...Sofa takes your GraphQL Schema, looks for available queries, mutations and subscriptions, and turns all of that into REST API. The idea behind Models is to not expose full objects in every response, especially if it's nested, not first-level data. For example, when fetching a list of chats you don't want to include all messages in the response, you want them to be just IDs (or links). Those messages would have to have their own endpoint. We call this type of data, a Model. In REST you probably call them Resources.
