    glfx.js

    glfx.js

    An image effects library for JavaScript using WebGL

    glfx.js is a JavaScript image-effects library that uses WebGL to apply real-time filters and transformations directly in the browser. It exposes a simple API where images are uploaded into GPU textures, processed with shader-based filters, and rendered to a WebGL canvas. Because the work is done on the GPU, many effects that would be too slow in pure JavaScript (like complex blurs, lens effects, or tilt-shift) can run interactively, even on large images.

    Svelte forms lib

    Svelte forms lib

    A lightweight library for managing forms in Svelte

This library helps you build forms by exposing an easy API for form creation, validation and submission.
