huggingface.js
huggingface.js is a collection of JavaScript libraries that provides programmatic access to the Hugging Face API, machine learning models, and repository management.
Huggingface.js is a set of JavaScript libraries designed to interact with the Hugging Face platform, including the Hub and Inference APIs. Developers use these tools to manage repositories, commit files, and access over 100,000 machine learning models for inference tasks. The collection includes specialized packages for parsing formats like GGUF, DDUF, and LeRobot datasets, as well as utilities for model templates and Ollama compatibility. It supports modern environments, including Node.js versions 18 and higher, Bun, Deno, and modern web browsers without requiring polyfills. These libraries provide TypeScript types to assist with development and integration within JavaScript or TypeScript codebases.
