This project is a customizable browser text editor and a schema-driven document framework designed for building React-based WYSIWYG content editors. It replaces standard text areas with a system that represents content as a structured data tree rather than flat HTML, allowing for precise manipulation and validation of documents. The framework serves as an extensible content management interface and a TypeScript UI component library. It enables the development of specialized authoring tools through a plugin system and the use of strongly typed building blocks to ensure consistency across docum

wasm-bindgen is a bindings generator and interop layer designed to map data types and functions across the boundary between WebAssembly and JavaScript. It functions as a foreign function interface that synthesizes the necessary boilerplate to enable bidirectional communication between Rust and the browser runtime. The project generates glue code and wrappers that automate the conversion of complex types, allowing Rust functions to be exported as JavaScript modules and browser APIs to be imported into Rust. It uses procedural macros to define these interfaces and synthesizes bindings based on

ts-reset is a TypeScript type enhancement library that overrides and augments the built-in type definitions for standard JavaScript APIs. Its core purpose is to replace unsafe any return types with stricter alternatives like unknown, forcing developers to explicitly validate data before using it. The library achieves this through global type augmentation and declaration merging, applying changes across the entire project without requiring per-file imports. The library differentiates itself by targeting specific pain points in everyday TypeScript usage. It relaxes type constraints on array

openapi-typescript is an OpenAPI TypeScript type generator and schema transformer. It converts JSON or YAML OpenAPI specification files into static TypeScript type definitions to provide end-to-end API type safety. The tool functions as a static type generator that transforms external API definitions into interfaces and types. It focuses on zero-runtime type enforcement, ensuring that data consistency is maintained via the TypeScript type system without adding overhead to production bundles. The project covers API type safety and schema conversion, facilitating the validation of request bodi

Arktype is a TypeScript runtime validation library and schema orchestrator. It synchronizes TypeScript types with runtime data validation, allowing users to define type-safe schemas that ensure unknown data adheres to specific structures during application execution. The project distinguishes itself by using set-theory type analysis to determine intersections and subtype compatibility, alongside JIT-compiled validation functions for optimized performance. It supports advanced type modeling through branded type constraints, recursive alias resolution, and the ability to generate runtime valida

This project is a Next.js SaaS starter kit and billing boilerplate designed for building subscription-based software services. It provides a pre-configured foundation that integrates a PostgreSQL database schema with Stripe to manage recurring billing, tiered pricing models, and customer payment portals. The implementation features a synchronization system that uses webhooks to mirror external product data and subscription states into a local relational database. It includes an authentication layer that links external identity providers to user accounts and manages secure session tracking. T

wasm-pack is a build tool and workflow orchestrator for compiling Rust code to WebAssembly. It coordinates the compilation process and generates the JavaScript glue code required to execute Rust logic within web browsers and server-side runtimes. The tool manages binary optimization to reduce file sizes and improve execution speed. It also functions as a package manager, bundling compiled WebAssembly modules into archives compatible with JavaScript registries and bundlers. The project covers language interoperability through the automatic generation of TypeScript type definitions. It further

MobX State Tree is a structured, tree-based state management library for JavaScript applications that combines typed model definitions with reactive snapshots and patch-based change tracking. It provides a reactive state container with runtime and compile-time type safety, where application state is defined as a tree of typed models with collocated actions, computed views, and lifecycle hooks for predictable state mutations. The library is built around an action-centric mutation model that encapsulates all state changes within named functions that directly modify the tree, supported by genera

Rushstack ist ein umfassendes Toolset für die Verwaltung groß angelegter TypeScript-Monorepos und bietet ein Framework für Build-Pipeline-Automatisierung, Abhängigkeitskoordination und statische Analyse. Es fungiert als inkrementeller Build-Orchestrator und Managementsystem, das darauf ausgelegt ist, Konsistenz und Performance über mehrere Pakete in einem geteilten Workspace hinweg zu wahren. Das System zeichnet sich durch ein Ausführungsmodell aus, das auf gerichteten azyklischen Graphen (DAGs) und inhalts-hash-basierter Inkrementalität basiert, was sicherstellt, dass nur betroffene Projekte neu gebaut werden. Es optimiert Entwicklungs-Workflows weiter durch Remote-Build-Artifact-Caching mit Integrationen für S3, Azure und HTTP und nutzt symlink-basiertes Workspace-Management für sofortige Sichtbarkeit lokaler Änderungen. Das Toolset deckt ein breites Spektrum an Funktionen ab, einschließlich automatisierter Release-Workflows, API-Vertragsanalyse und der Durchsetzung von Code-Qualität im Unternehmen durch standardisierte Linting-Profile. Es bietet zudem umfassende Unterstützung für Asset-Bundling, TypeScript-Transpilierung und die Generierung von Typdefinitionen aus JSON-Schemas und statischen Assets. Zusätzliche Aufgabenbereiche umfassen Lokalisierungsmanagement, die Generierung von Lizenzhinweisen und die Orchestrierung von Command-Line-Interfaces mit synchronisierter Prozessausgabe.

stc is a TypeScript type checker implemented entirely in Rust, designed to validate type correctness in TypeScript source code with native performance and memory safety. It operates as a no-emitting type validator, meaning it checks types only and does not produce JavaScript output, reducing overhead compared to a full compiler. The checker is built around a zero-false-positive design, reporting only errors that are provably certain from the type system, prioritizing correctness over speculative warnings. The tool distinguishes itself through parallel file processing, analyzing source files c

react-native-config ist ein plattformübergreifender Manager für mobile Umgebungen und ein Tool für native Build-Konfigurationen. Es implementiert die Prinzipien der Twelve-Factor App, indem es umgebungsspezifische Einstellungen vom Anwendungscode trennt. Das Projekt bietet einen Mechanismus, um Umgebungsvariablen während des Kompilierungsprozesses direkt in native Projektdateien und Build-Einstellungen einzufügen. Es fungiert zudem als typsicherer Konfigurations-Loader, der TypeScript-Definitionen für Umgebungsvariablen generiert, um Autovervollständigung und Sicherheit zu gewährleisten. Das Tool verwaltet Multi-Umgebungs-Konfigurationen, indem es spezifische Variablen basierend auf aktiven Build-Targets oder Deployment-Stufen aus Dateien lädt. Es überbrückt diese Werte vom nativen Plattformspeicher zur JavaScript-Runtime.
