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 It is explicitly deprecated and no longer actively maintained, with the author recommending tonic instead.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
