A React library providing a higher-order component that maps nested prop changes across the component tree to a global side effect. It gathers props from all mounted instances, reduces them to state, and invokes a client-side handler, with server-side peek/rewind support.

Use cases

• set document body style based on current screen
• fire flux actions declaratively from component props
• manage global side effects from nested components
• collect props across the whole react tree
• handle side effects differently on server and client

When to choose

• you need a global side effect driven by props from multiple nested components
• you want innermost-nested props to win when merging state
• you need server-side access to reduced state via peek and rewind

When to avoid

• you only need side effects from a single component, where componentDidUpdate suffices
• you use a modern state management or document head manager instead
• the project is unmaintained and you need active support for latest React versions
