Module Dependency Diagrams

With IntelliJ IDEA, you can get visualization of imports and exports within a context in JavaScript and TypeScript projects.

Building a module dependency diagram

  • Choose Diagrams | Show Diagram on the context menu of a JavaScript, TypeScript, or HTML file or on a context menu of a folder.

    The action is not available for node_modules and for Excluded folders.

  • If the action is invoked on a folder where multiple types of diagrams can be built, additionally choose JavaScript Module Dependency Diagram from the Select Diagram Type pop-up list.

Analyzing a module dependency diagram

IntelliJ IDEA analyzes the import and require statements and script tags in the selected file or in all the files in the selected folder recursively and in a separate tab displays a diagram that shows how these files depend on each other:

  • A diagram consists of a number of rectangles. Each of them shows the name of the analyzed selected file and a list of detected imports. If an import is resolved, an icon that indicates the type of the imported symbol (e.g. variable or icons nodes field svg) is shown next to it.
  • An arrow from an analyzed file points at the target file from which the detected imports are made. If the target file is a library, its name is displayed on the grey background. If an import from a library is not resolved, the target file is displayed as a grey rectangle with red border.
  • Resolved imports and exports are marked with the import icon or icons toolbarDecorator export svg icons respectively.

Navigating from the diagram to the source code

  • To jump from a diagram to a file, right-click the file and choose Jump to source on the context menu.
  • To navigate to a specific import statement in the source code, right-click the required file in the diagram, choose Jump to on the context menu, and then choose the symbol to jump to from the Select Navigation Target pop-up list:
