|
6 | * Decorator that marks a class as a [provider](https://docs.nestjs.com/providers).
|
7 | * Providers can be injected into other classes via constructor parameter injection
|
8 | * using Nest's built-in [Dependency Injection (DI)](https://docs.nestjs.com/providers#dependency-injection)
|
9 | * system.
|
10 | *
|
11 | * When injecting a provider, it must be visible within the module scope (loosely
|
12 | * speaking, the containing module) of the class it is being injected into. This
|
13 | * can be done by:
|
14 | *
|
15 | * - defining the provider in the same module scope
|
16 | * - exporting the provider from one module scope and importing that module into the
|
17 | * module scope of the class being injected into
|
18 | * - exporting the provider from a module that is marked as global using the
|
19 | * `@Global()` decorator
|
20 | *
|
21 | * Providers can also be defined in a more explicit and imperative form using
|
22 | * various [custom provider](https://docs.nestjs.com/fundamentals/custom-providers) techniques that expose
|
23 | * more capabilities of the DI system.
