## What it is
BigPipe is a Node.js web framework that decomposes pages into reusable chunks called Pagelets and pipelines them through execution stages in the server and browser, enabling progressive rendering for better front-end performance. It is inspired by Facebook's BigPipe concept and is composed of over 20 npm modules.

## Use cases
- build a node.js web app with progressive page rendering
- decompose web pages into reusable pagelet components
- improve perceived page load performance by streaming HTML early
- serve chunks of a page as data becomes available instead of blocking on full template render
- build a modular real-time web framework on node

## When to choose
- you want Facebook-style BigPipe progressive rendering in Node.js
- your pages have many independent slow data sources and you want to flush early
- you prefer a composable framework built from small modules

## When to avoid
- you need a maintained framework with modern Node.js support (last release 2016, targets Node 0.10)
- you want a large ecosystem and community support
- you need server-side rendering with modern tooling like React or Next.js
