What are the steps to identify and fix CD (Circular Dependencies) in NX and React?

In my current project, I'm working on a Monorepo consisting of an apps folder containing three distinct projects namely admin, commerce and vendor. Along with that, there is a separate libs folder consisting of various folders such as components and so on.

Recently, I learned about the concept of Circular Dependencies and I want to check if my project has any. But as I am using NX and React, I am not sure how to do that. While researching a bit, I came across madge, an NPM package that detects circular dependencies, but I couldn't get it to work with my current setup.

Can anyone suggest a proper way to detect circular dependencies in NX and React? Any input is highly appreciated.

You can use the madge package to detect circular dependencies in your project. You can install it using the following command:
After installing it, you can run the following command to detect circular dependencies:
This will output a list of all circular dependencies in your project. You can also use the --format flag to output the list in different formats such as amd, cjs, es6, json, ts, etc.In addition to that, you can also enable automatically detecting dependencies from source code by adding the following configuration to your nx.json file: 
{
  "pluginsConfig": {
    "@nx/js": {
      "analyzeSourceFiles": true
    }
  }
}
Nx 15 and lower use @nrwl/ instead of @nx/. Other presets default this property to true.I hope this helps! Let me know if you have any other questions.

Yes, in NX you can check for circular dependencies between apps and libs by running the following command in your terminal:
This will generate a dependency graph for all the affected projects in your Monorepo. If you want to specifically check for circular dependencies between your apps and libs, you can use the --include=apps,libs flag:
This will generate a dependency graph only for the apps and libs folders. If you prefer to use madge to check for circular dependencies, you can install it as a dev dependency in your Monorepo by running the following command:
Then, you can run the following command to generate a graphical representation of your project's dependencies:
This will generate an image file (output.png) in the root directory of your project that represents the dependencies between your apps and libs. Keep in mind that while madge can be helpful for visualizing dependencies, it's not always accurate and may not catch all circular dependencies. It's still a good idea to manually review your code for potential circular dependencies and refactor your code as necessary.
