+Nest is built around the strong design pattern commonly known as **Dependency injection**. We recommend reading a great article about this concept in the official [Angular](https://angular.dev/guide/di) documentation.
 
 In Nest, thanks to TypeScript capabilities, it's extremely easy to manage dependencies because they are resolved just by type. In the example below, Nest will resolve the `catsService` by creating and returning an instance of `CatsService` (or, in the normal case of a singleton, returning the existing instance if it has already been requested elsewhere). This dependency is resolved and passed to your controller's constructor (or assigned to the indicated property):

 The ability to go back in time lets you investigate and troubleshoot the issue by comparing the current graph with the previous one. Depending on how you set things up, every pull request (or even every commit) will have a corresponding snapshot in the registry, so you can easily go back in time and see what changed. Think of Devtools as a Git but with an understanding of how Nest constructs your application graph, and with the ability to **visualize** it.
