nivo
A rich set of dataviz components
nivo provides a rich set of dataviz components, built on top of the awesome d3 and Reactjs libraries. Several libraries already exist for React d3 integration, but just a few provide server side rendering ability and fully declarative charts. In order to use nivo, you have to install the @nivo/core package and then choose some of the scoped @nivo packages according to the charts you wish to use. Given an array of data series having an id and a nested array of points (with x, y properties), it will compute the line for each data series. All datum having null x or y will be treated as holes, thus portions of the corresponding line will be skipped. You can fully customize it using the circleComponent property to define your own, if you wish to do so you should have a look at the default SVG component to get started. Bar chart which can display multiple data series, stacked or side by side. Also supports both vertical and horizontal layout, with negative values descending below the x axis. -

Dexie.js
A Minimalistic Wrapper for IndexedDB
Dexie was written to be straightforward and easy to learn. If you've ever had to work with native IndexedDB then you'll certainly appreciate Dexie's concise API. What good is any development tool without great documentation? Dexie is thoroughly explained, and examples are available to help you on your way. Dexie has near-native performance. Its bulk operations utilize an often-overlooked feature in IndexedDB, ignoring success callbacks when possible. Offline databases are groovy! But without keeping the database in sync with a server, you're missing a great deal. Dexie.js solves these limitations and provides a neat database API. Dexie.js aims to be the first-hand choice of a IDB Wrapper Library due to its well thought-through API design, robust error handling, extendability, change tracking awareness and its extended KeyRange support (case insensitive search, set matches and or operations). -

Flow Typed
A central repository for Flow library definitions
High-quality library definitions for Flow. flow-typed is a repository of third-party library interface definitions for use with Flow. When you start a project with Flow, you likely want to use some third-party libraries that were not written with Flow. By default, Flow will just ignore these libraries leaving them untyped. As a result, Flow can't give errors if you accidentally misuse the library (nor will it be able to auto-complete the library). To address this, Flow supports library definitions which allow you to describe the interface of a module or library separate from the implementation of that module/library. The flow-typed repo is a collection of high-quality library definitions, tests to ensure that definitions remain high quality, and tools to make it as easy as possible to import them into your project. All you have to do when you add one or more new dependencies to your project is run flow-typed install. -

HyperUI
Free Tailwind CSS v4 components for your next project
HyperUI is a large, copy-and-paste library of Tailwind CSS components aimed at speeding up interface building without adding heavy JavaScript. It groups components by common product needs—navigation, hero sections, pricing, forms, cards, tables, and full e-commerce flows—so teams can assemble pages quickly from consistent building blocks. Each snippet is written as semantic HTML with Tailwind utility classes, making it easy to customize spacing, color, and typography through a project’s Tailwind config. The components are responsive by default, using grid and flex patterns that adapt cleanly from mobile to widescreen layouts. Accessibility is treated pragmatically: markup favors proper roles and focus states, and most interactive behaviors can be wired with lightweight libraries or framework code if desired. Because everything is plain markup, adoption is frictionless in any stack (React, Vue, Svelte, Rails, Laravel), and designers can tweak styling without refactoring component logic. -

Immutable.js
Immutable collections for JavaScript
Immutable.js offers a collection of Persistent Immutable data structures for JavaScript. Immutable data is unchangeable once created, which makes application development so much simpler.

The data structures that Immutable.js provides include List, Stack, Map, OrderedMap, Set and more. These structures are highly efficient on modern JavaScript VMs, and minimize the need to cache or copy data. -
