Universal JavaScript applications are tough to setup. Either you buy into a framework like Next.js or react-server, fork a boilerplate, or set things up yourself. Aiming to fill this void, Razzle is a tool that abstracts all complex configuration needed for SSR into a single dependency--giving you the awesome developer experience of create-react-app, but then leaving the rest of your app's architectural decisions about frameworks, routing, and data fetching up to you. With this approach, Razzle not only works with React, but also Reason, Elm, Vue, Angular and what ever comes next.

Async is a utility module which provides straight-forward, powerful functions for working with asynchronous JavaScript. Although originally designed for use with Node.js and installable via npm i async, it can also be used directly in the browser.
 
Async provides around 70 functions that include the usual 'functional' suspects (map, reduce, filter, each…) as well as some common patterns for asynchronous control flow (parallel, series, waterfall…). All these functions assume you follow the Node.js convention of providing a single callback as the last argument of your asynchronous function -- a callback which expects an Error as its first argument -- and calling the callback once.

 A practical functional library for JavaScript programmers. There are already several excellent libraries with a functional flavor. Typically, they are meant to be general-purpose toolkits, suitable for working in multiple paradigms. Ramda has a more focused goal. We wanted a library designed specifically for a functional programming style, one that makes it easy to create functional pipelines, one that never mutates user data.

OrbitDB is a serverless, distributed, peer-to-peer database. OrbitDB uses IPFS as its data storage and IPFS Pubsub to automatically sync databases with peers. It's an eventually consistent database that uses CRDTs for conflict-free database merges making OrbitDB an excellent choice for decentralized apps (dApps), blockchain applications and offline-first web applications.
 
OrbitDB provides various types of databases for different data models and use cases:
<ul>
<li><a href="https://github.com/orbitdb/orbit-db/blob/master/API.md#orbitdblognameaddress" target="_blank">log</a>: an immutable (append-only) log with traversable history. Useful for "latest N" use cases or as a message queue.</li>
<li><a href="https://github.com/orbitdb/orbit-db/blob/master/API.md#orbitdbfeednameaddress" target="_blank">feed</a>: a mutable log with traversable history. Entries can be added and removed. Useful for "shopping cart" type of use cases, or for example as a feed of blog posts or "tweets".</li>
<li><a href="https://github.com/orbitdb/orbit-db/blob/master/API.md#orbitdbkeyvaluenameaddress" target="_blank">keyvalue</a>: a key-value database just like your favourite key-value database.</li>
<li><a href="https://github.com/orbitdb/orbit-db/blob/master/API.md#orbitdbdocsnameaddress-options" target="_blank">docs</a>: a document database to which JSON documents can be stored and indexed by a specified key. Useful for building search indices or version controlling documents and data.</li>
<li><a href="https://github.com/orbitdb/orbit-db/blob/master/API.md#orbitdbcounternameaddress" target="_blank">counter</a>: Useful for counting events separate from log/feed data.</li>
