Payload is a headless content management system and application framework that uses a code-first approach to define data schemas and administrative interfaces. By utilizing a centralized, type-safe configuration object, it automatically generates database schemas, API endpoints, and a fully customizable admin panel. The system is built on a database-agnostic architecture, allowing it to interface with various storage engines while providing a unified, type-safe API for server-side operations, REST, and GraphQL. What distinguishes Payload is its deep extensibility and developer-centric design.
Computes and derives data dynamically during API responses without database persistence.
gqlgen is a schema-first Go library designed to build type-safe GraphQL servers. It functions as a code generation engine that transforms declarative GraphQL schema definitions into strongly-typed Go source code, ensuring strict alignment between the API contract and the underlying implementation. The framework distinguishes itself through its deep integration with the Go type system and its highly extensible build pipeline. By using schema-first development, it automates the creation of server boilerplate and resolver stubs, allowing developers to map schema fields directly to Go structs and
Allows specifying required data sets that are injected into resolver arguments to enable computed field dependencies.
Miller is a command-line data processor used for filtering, transforming, and aggregating name-indexed tabular data. It functions as a tool for querying and reshaping records across multiple file formats, serving as a converter between CSV, JSON, and YAML. The tool distinguishes itself by using a name-indexed data model, allowing users to manipulate fields by name rather than numeric position. It utilizes single-pass streaming algorithms to compute statistics and summaries on large datasets that exceed available system memory. Its capabilities cover data transformation and analysis, includin
Creates new data fields by applying mathematical or string operations to existing values.
Baserow is a self-hosted, no-code relational database platform built on PostgreSQL. It provides a spreadsheet-like interface for structuring and managing data without writing code, while exposing all database resources via a REST API to support headless architectures. The platform distinguishes itself by integrating large language models and embedding servers to power AI assistants and automated data generation. It further extends its utility as a no-code application builder, allowing users to create custom internal portals, dashboards, and business tools using visual logic and managed data.
Supports view filters and sorting logic for dynamically derived computed fields based on their result type.
Mapshaper este un instrument pentru procesarea, simplificarea și convertirea datelor vectoriale geografice, disponibil ca interfață de linie de comandă, instrument de browser web și bibliotecă Node.js. Funcționează ca un proiector de coordonate, convertor de date vectoriale și optimizator de active pentru hărți web, conceput pentru a transforma seturile de date spațiale între diferite sisteme de referință de coordonate și formate de fișiere. Proiectul se distinge prin simplificarea geometriei care păstrează topologia, ceea ce reduce numărul de noduri (vertex) menținând în același timp limitele partajate pentru a preveni golurile și suprapunerile. Optimizează în continuare activele pentru web prin cuantificarea coordonatelor și filtrarea atributelor pentru a reduce dimensiunile fișierelor. Sistemul acoperă o gamă largă de capabilități, inclusiv reproiectarea coordonatelor folosind șiruri PROJ și coduri EPSG, și conversia datelor între formate precum Shapefile, GeoJSON, TopoJSON, GeoPackage și KML. Oferă instrumente extinse de procesare a geometriei pentru buffering, clipping, dizolvare și repararea topologiilor, precum și utilitare de gestionare a datelor pentru unirea atributelor, filtrare și transformare. În plus, include funcții de vizualizare pentru generarea de exporturi SVG stilizate, graticule și hărți cu simboluri proporționale. Capabilitățile de procesare spațială pot fi integrate direct în aplicațiile JavaScript și în pipeline-urile de build prin biblioteca sa Node.js.
Runs expressions on each feature to create or update attribute fields based on existing data.
apollo-ios is a GraphQL client library for iOS and Apple platforms that enables type-safe network communication. It transforms GraphQL operations into generated Swift models, ensuring that network responses are validated at compile time to eliminate manual mapping. The library features a normalized cache manager that stores entities in a flat structure to maintain data consistency across different application views. It also optimizes network performance using hash-based persisted queries to reduce payload sizes and supports real-time data streaming via WebSockets or HTTP subscriptions. The p
Calculates field values by fetching required data from a different subgraph before final resolution.
Practicalnode is a comprehensive educational resource and backend development framework for mastering server-side programming with Node.js. It provides a structured approach to building scalable network services, REST APIs, and real-time applications using asynchronous JavaScript. The project serves as a detailed implementation guide for several core backend patterns, including MongoDB data modeling and the construction of REST API development kits. It emphasizes a specific workflow for Docker containerization and offers a variety of strategies for managing user identity through stateless tok
Implements mock fields that compute values dynamically at runtime via getters without persistent database storage.
