Realize For React

As React applications scale, it becomes more difficult to track state and to have a holistic overview of the component hierarchy. Realize is a tool to help developers visualize the structure and state flow of their React applications, especially when they are growing in scale and complexity. It currently supports React v.16.8.


👩‍💻 How to use it

  1. Install the extension from the Firefox store & Chrome store
  2. Navigate to your React website
  3. Open the dev tools window and select the Realize Panel
  4. Trigger a state change to see the component tree populate


  • Realize requires React Dev Tools to be installed before use.
  • Realize is best used on non-deployed applications. This uglification of deployed websites makes the component structure pretty unreadable.

🔥 Key Features

Zoom & Pan - Hold down shift to enable dragging and zooming on the tree (to recenter just click the center button)
Component Focus - Click on a node to view state, props and children in the right and panel
State Flow - Click the 'state' toggle to show state flow on the tree. Stateful components have blue nodes and state flow is show by blue links
Search and Highlight - Enter a component name in the search bar to see all matching nodes pulsate

💻 Installing locally

  1. Clone the repo onto your computer git clone
  2. Run npm i from inside the root directory
  3. Run npm build
  4. Load the extension from the build/extension folder into your browser of choice:
