icepick - Utilities for treating frozen JavaScript objects as persistent immutable collections

  •    Javascript

Utilities for treating frozen JavaScript objects as persistent immutable collections. Object.freeze() is a quick and easy way to get immutable collections in plain JavaScript. If you recursively freeze an object hierarchy, you have a nice structure you can pass around without fear of mutation. The problem is that if you want to modify properties inside this hierarchical collection, you have to return a new copy with the properties changed.

react-absolute-grid - An absolutely positioned, animated, filterable, sortable, drag and droppable, ES6 grid for React

  •    Javascript

An absolute layout grid with animations, filtering, zooming, and drag and drop support. Use your own component as the grid item. See the Demo. The idea behind AbsoluteGrid is high performance. This is achieved by using Translate3d to position each item in the layout. Items are never removed from the DOM, instead they are hidden. For best performance you should avoid re-arranging or removing items which you pass into AbsoluteGrid, instead you can use the filtered and sort properties to hide or sort an item. Those properties are customizable using the keyProp and filterProp properties. In addition, all data passed must be immutable so that we don't waste any renders.

A tree data structure that emits events on updates, even if the modification is emited by one of the leaves, making it easier to think in a reactive way. Are you looking for an immutable.js alternative? Freezer is made with React.js in mind and it uses real immutable structures. It is the perfect store for you application.

Capsule - The Capsule Hash Trie Collections Library

  •    Java

Capsule aims to become a full-fledged (immutable) collections library for Java 8+ that is solely built around persistent tries. The library is designed for standalone use and for being embedded in domain-specific languages. Capsule still has to undergo some incubation before it can ship as a well-rounded collection library. Nevertheless, the code is stable and performance is solid.


pyrsistent - Persistent/Immutable/Functional data structures for Python

  •    Python

Pyrsistent is a number of persistent collections (by some referred to as functional data structures). Persistent in the sense that they are immutable. All methods on a data structure that would normally mutate it instead return a new copy of the structure containing the requested updates. The original structure is left untouched.

moreartyjs - Morearty.js - centralized state management for React in pure JavaScript

  •    Javascript

Morearty.js is a thin layer on top of React (implemented as a mixin) providing better state management facilities in the manner of Om but written in pure JavaScript. Underneath, Morearty leverages immutable data structures, provided by Facebook's Immutable library, which hold the state of an application. That state is described by a single Binding object and all state transitions are performed through it. When an application component needs to delegate a part of its state to a sub-component, it can create a sub-binding which points to a nested location within the global state and is fully synchronized with the original binding. This way every component knows only what it should know and the entire state is effectively encapsulated. Morearty detects any changes automatically and triggers re-rendering. Moreover, each component gets a correctly defined shouldComponentUpdate method that compares the component's state using straightforward JavaScript strict equals operator ===. So, only the components whose state was altered are re-rendered.

omniscient - A library providing an abstraction for React components that allows for fast top-down rendering embracing immutable data for js

  •    Javascript

We can happily announce that as of React 16.6, Omniscient.js can enjoy retirement after a job well done. The new React.memo API can for most cases replace the Omniscient decorator with your own areEqual function. It's not exactly the same, but we feel that it is close enough for most cases. Thanks for supporting Omniscient all these years. Do fast top-down rendering embracing immutable data and functional programming.

eslint-plugin-immutable - ESLint plugin to disable all mutation in JavaScript.

  •    Javascript

This is an ESLint plugin to disable all mutation in JavaScript. Think this is a bit too restrictive? Well if you're using Redux and React, there isn't much reason for your code to be mutating anything. Redux maintains a mutable pointer to your immutable application state, and React manages your DOM state. Your components should be stateless functions, translating data into Virtual DOM objects whenever Redux emits a new state. These ESLint rules explicitly prohibit mutation, effectively forcing you to write code very similar to Elm in React. There's no reason to use let in a Redux/React application, because all your state is managed by either Redux or React. Use const instead, and avoid state bugs altogether.

immutable-devtools - Chrome Dev Tools custom formatter for Immutable-js values

  •    Javascript

The Immutable library is fantastic, but inspecting immutable collections in Chrome's Dev Tools is awkward. You only see the internal data structure, not the logical contents. For example, when inspecting the contents of an Immutable List, you'd really like to see the items in the list.Chrome (v47+) has support for custom "formatters". A formatter tells Chrome's Dev Tools how to display values in the Console, Scope list, etc. This means we can display Lists, Maps and other collections, in a much better way.

redux-immutable - redux-immutable is used to create an equivalent function of Redux combineReducers that works with Immutable

redux-immutable is used to create an equivalent function of Redux combineReducers that works with Immutable.js state. When Redux createStore reducer is created using redux-immutable then initialState must be an instance of Immutable.Collection.

Immutable-js - Immutable persistent data collections for Javascript which increase efficiency and simplicity

  •    Javascript

Immutable data cannot be changed once created, leading to much simpler application development, no defensive copying, and enabling advanced memoization and change detection techniques with simple logic. Persistent data presents a mutative API which does not update the data in-place, but instead always yields new updated data.

Paguro - Immutable Collections and Functional Transformations for the JVM

  •    Java

Immutable Clojure collections and a Transformation abstraction for Java 8+, immutably, type-safely, and with good performance. It provide support for RRB Tree, which is an immutable List (like Clojure's PersistentVector) that also supports random inserts, deletes, and can be split and joined back together in logarithmic time.

GreenSock-JS - GreenSock's GSAP JavaScript animation library (including Draggable).

  •    Javascript

GSAP is a JavaScript library for creating high-performance animations that work in every major browser. No other library delivers such advanced sequencing, reliability, API efficiency, and tight control while solving real-world problems on over 4 million sites. GSAP works around countless browser inconsistencies; your animations 'just work'. CSS properties, SVG, canvas libraries, custom properties of generic objects, colors, strings...animate anything! At its core, GSAP is a high-speed property manipulator, updating values over time with extreme accuracy. It's up to 20x faster than jQuery! See the "Why GSAP?" article for what makes GSAP so special. Unlike monolithic frameworks that dictate how you structure your apps, GSAP is completely flexible; sprinkle it wherever you want. React, Vue, Angular or vanilla JS - doesn't matter. Simply put, GSAP is the most robust high-performance animation library on the planet, which is probably why every major ad network excludes it from file size calculations.

react-cursor - Immutable state for React.js

  •    Javascript

Cursors are a tool for working with recursive or deeply nested data, immutably. react-cursor is a javascript port of an abstraction that I first saw in ClojureScript. This implementation is decoupled from any rendering library and is very small. Cursors are useful in UI programming, because UIs are tree shaped and naturally have tree-shaped state. Cursors let your app hold all its state in one place at the root of the UI tree; thus the root is stateful, and all downtree views are stateless.

immu - A TINY, fail-fast, lazy, immutable Javascript objects library.

  •    Javascript

A TINY, fail-fast, lazy, "naked", simple immutable Javascript objects library. Immu does not attempt to add functionality to Arrays, introduce complex data structures like Map and Set, or provide a complete solution with cursors and stores. Immu is meant to be the simplest possible solution to providing immutable objects while maintaining the native API for those objects (including Array methods).

list - 🐆 An immutable list with unmatched performance and a comprehensive functional API.

  •    TypeScript

A fast immutable list with a functional API. List is a purely functional alternative to arrays. It is an implementation of a fast persistent sequence data structure. Compared to JavaScript's Array List has three major benefits.

PCollections - A Persistent Java Collections Library

immer - Postmodern immutable and persistent data structures for C++

  •    C++

immer is a library of persistent and immutable data structures written in C++. These enable whole new kinds of architectures for interactive and concurrent programs of striking simplicity, correctness, and performance. In the last few years, there has been a growing interest in immutable data structures, motivated by the horizontal scaling of our processing power and the ubiquity of highly interactive systems. Languages like Clojure and Scala provide them by default, and implementations for JavaScript like Mori and Immutable.js are widely used, specially in combination with modern UI frameworks like React.
