Sharp is a Node-API module that wraps libvips, making it the practical choice when you need to process images in a Node.js environment without the overhead of a full ImageMagick installation. The README claims 4x-5x faster resizing compared to ImageMagick and GraphicsMagick, and it handles the tricky parts correctly: ICC colour profiles, alpha transparency, and auto-orientation all work without surprises. Beyond simple resizing, it covers rotation, extraction, compositing, and gamma correction — useful for building image pipelines that would otherwise require multiple tools stitched together. One concrete upside for local development: most macOS, Windows, and Linux machines need no extra system libraries to run it.

three.js (mrdoob/three.js) is an open-source JavaScript library for real-time 3D graphics in the browser, released under the MIT license. It renders through built-in WebGL and WebGPU renderers, with SVG and CSS3D renderers shipped as separate addons. It's the library behind the scene-graph API shown in its own README example: a camera, a geometry, a material, and a mesh composed into a scene and redrawn each frame through an animation loop.

Immich is a self-hosted photo and video management app written mostly in TypeScript: a NestJS backend, a SvelteKit web client, and Flutter mobile apps. It backs up photos automatically from your phone, clusters faces, indexes content with CLIP embeddings for text search, and plots shots on a map — the feature set Google Photos users expect, running on a server you own instead of a vendor's cloud. It's licensed AGPL-3.0 and sits at 109,695 GitHub stars.

Chart.js is an open-source JavaScript library at chartjs/Chart.js for drawing charts onto an HTML5 canvas element, the output format its own GitHub description names directly. The project has stars and forks on GitHub, ships under the MIT license, and organizes its documentation into getting-started, data-structure, configuration, chart-type, and axes sections rather than one long page.
