Mercury is a modular JavaScript frontend framework built on virtual-dom, offering immutable virtual DOM structures and unidirectional state management similar to React. It is explicitly deprecated and no longer actively maintained, with the author recommending tonic instead.

Use cases

  • build a modular frontend app with virtual-dom
  • unidirectional data flow state management in JavaScript
  • server-side rendering of frontend components
  • learn how a React-like framework works internally
  • mix a frontend framework with Backbone or Immutable.js

When to choose

  • studying framework design or virtual-dom concepts
  • maintaining a legacy codebase already using mercury

When to avoid

  • starting any new frontend project
  • needing long-term maintenance or community support
  • wanting a modern component model or ecosystem
