A dependency graph is a simple way of seeing which components are dependent on one another. The purpose is to show relationships and how components are structured to form the overall architecture of your application.

It can be generated in your console using npm commands. This allows you to see parent child relationships at a glance. It also lets you see how a component is reliant on another.

The following are the benefits of using a dependency graph:

  1. Make sure app is following Parent/Child Component architecture.
  2. Allows us to see what components are dependent on the one we are working on, so that we may run linting, or unit testing only, based on these components.
  3. Visualize all components in use across app.

You can create a dependency graph using npm. You can generate a dependency graph using compodoc, but this is usually regulated to demo mode. When in development, if you're using nx, nrwl comes packaged with a dependency graph.

npm run affected:dep-graph;npm run dep-graph;

This will show you something like:
