Explain the difference between the `providers` and `exports` properties in the definition of a Nest.js module.

Question

What's the difference between the `providers` and `exports` properties in the definition of a Nest.js module?

Accepted Answer

`providers` registers services or other classes for dependency injection inside the module, while `exports` determines which services or classes can be used by other modules that import this module.

Answer

`providers` is used to define routes, while `exports` is used to define controllers.

Answer

Both properties serve the same purpose and are therefore interchangeable.

Answer

`providers` is only for services external to the module, while `exports` is for services intended to be shared.
