    GraphQL Scalars

    GraphQL Scalars

    A library of custom GraphQL Scalars for creating precise schemas

    ...However, for all of GraphQL's greatness, it is missing a couple of things that we have (and you might) find very useful in defining your schemas. Namely GraphQL has a limited set of scalar types, and we have found there are some additional scalar types that are useful in being more precise in our schemas. Thankfully, those sharp GraphQL folks provided a simple way to add new custom scalar types if needed. That's what this package does. GraphQL Scalars is a library of custom GraphQL scalar types for creating precise type-safe GraphQL schemas. ...

    BSON parser

    BSON parser

    BSON Parser for node and browser

    BSON parser is the core JavaScript implementation of BSON (Binary JSON), the data format used by MongoDB to represent documents on the wire and in storage. It provides encoding and decoding capabilities so JavaScript environments like Node.js and browsers can serialize rich data structures (including types not native to JSON) into the compact, efficient BSON binary representation used by MongoDB drivers and servers. Value types such as ObjectId, Binary, UTC datetime, Decimal128, and Long are provided as first-class objects, enabling precise representation of data that would otherwise be lossy or awkward in plain JSON. js-bson is designed for performance, with optimized algorithms for reading and writing binary data, minimizing overhead in database operations. ...

    React & Redux in TypeScript

    React & Redux in TypeScript

    The complete guide to static typing in "React & Redux" apps

    React Redux TypeScript Guide is a comprehensive reference for building strongly typed React and Redux applications with TypeScript. It focuses on maintaining complete type safety while minimizing redundant annotations and manual type declarations. The guide explains React component types, hooks, events, context, higher-order components, and Redux-connected components. It demonstrates how type inference and control-flow analysis can keep application types concise and maintainable. Redux sections cover actions, reducers, selectors, asynchronous flows, middleware integrations, and store typing. A bundled playground project provides working examples that readers can clone and experiment with in a real TypeScript environment.

    FlowGram

    FlowGram

    Extensible workflow development framework

    ...Instead of shipping as a ready-made product, it provides the building blocks — a canvas for wiring together nodes, a form engine for configuring node parameters, a variable-scope and type-inference engine, and a set of “materials” (pre-built node types such as code execution, conditional logic, LLM calls, etc.) that can be composed into larger workflows. This makes FlowGram highly flexible: you can prototype data-processing pipelines, AI-agent flows, automation scripts, or even business process automation without writing all the plumbing yourself. The framework supports both free-layout canvases (for free-form graphs) and fixed-layout canvases (for more structured flowcharts, including loops, branches, compound nodes), giving you visual freedom depending on your use-case.
