The project covers GraphQL client automation, type generation, and workflow optimization. I

Old repo of Nuxt 3 framework, now on nuxt/nuxt

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 est un générateur de liaisons et une couche d'interopérabilité conçue pour mapper les types de données et les fonctions à travers la frontière entre WebAssembly et JavaScript. Il fonctionne comme une interface de fonction étrangère qui synthétise le code répétitif nécessaire pour permettre une communication bidirectionnelle entre Rust et le runtime du navigateur. Le projet génère du code de liaison et des wrappers qui automatisent la conversion de types complexes, permettant aux fonctions Rust d'être exportées en tant que modules JavaScript et aux API de navigateur d'être importées dans Rust. Il utilise des macros procédurales pour définir ces interfaces et synthétise les liaisons basées sur les définitions de type Rust. Le système gère la mémoire via le passage de pointeurs de mémoire linéaire et gère l'échange de ressources en utilisant des handles de mémoire gérés par JavaScript. Il repose sur une convention d'appel compatible avec l'ABI C pour passer des entiers et des flottants primitifs entre le module et l'hôte.

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 est un ensemble d'outils complet pour gérer les monorepos TypeScript à grande échelle, fournissant un framework pour l'automatisation des pipelines de build, la coordination des dépendances et l'analyse statique. Il fonctionne comme un orchestrateur de build incrémental et un système de gestion conçu pour maintenir la cohérence et la performance à travers de multiples packages dans un espace de travail partagé. Le système se distingue par un modèle d'exécution basé sur des graphes acycliques dirigés et un incrémentalisme basé sur le hash de contenu, qui assure que seuls les projets affectés sont reconstruits. Il optimise davantage les workflows de développement via la mise en cache distante des artefacts de build avec des intégrations pour S3, Azure et HTTP, et utilise la gestion d'espace de travail basée sur des liens symboliques pour une visibilité immédiate des changements locaux. L'ensemble d'outils couvre un large éventail de capacités incluant des workflows de release automatisés, l'analyse de contrat API et l'application de la qualité de code en entreprise via des profils de linting standardisés. Il fournit également un support étendu pour le bundling d'actifs, la transpilation TypeScript et la génération de définitions de type à partir de schémas JSON et d'actifs statiques. Des domaines utilitaires supplémentaires incluent la gestion de la localisation, la génération d'avis de licence et l'orchestration d'interfaces de ligne de commande avec une sortie de processus synchronisée.

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 est un gestionnaire d'environnement mobile multiplateforme et un outil de configuration de build natif. Il implémente les principes de configuration d'application "twelve-factor" en séparant les paramètres spécifiques à l'environnement du code de l'application. Le projet fournit un mécanisme pour injecter des variables d'environnement directement dans les fichiers de projet natifs et les paramètres de build pendant le processus de compilation. Il fonctionne également comme un chargeur de configuration typé qui génère des définitions TypeScript pour les variables d'environnement afin d'assurer l'autocomplétion et la sécurité. L'outil gère les configurations multi-environnements en chargeant des variables spécifiques à partir de fichiers basés sur des cibles de build actives ou des étapes de déploiement. Il fait le pont entre ces valeurs du stockage de la plateforme native vers le runtime JavaScript.
