React-vdom upgraded to React v0.12.0

Hello, I wrote this handy little library for testing purposes: you can extract the vdom from a React component and test it against a JSON with simple tools like assert.deepEqual() and without a real DOM. The extracted vdom has the following type definition:

    type Node = {
      tag: string,
      attrs: object<name, value>,
      children: undefined | null | Node | Array<Node>
    }

If your component handle a private state, you can inject a state to test different configurations.

This is an example of massive use in a form generation library:

Hope it can help you too.
