# NestJS Provider Helper

This helper creates a provider structure for NestJS modules in a opinionated way, where every provider must be a implementation of a interface

The ProviderHelper class exposes static methods to create ClassProviders, FactoryProviders, ExistingProviders and ValueProviders

### Installing

```sh

npm install nestjs-provider-helper

# or

yarn add nestjs-provider-helper

```

### ClassProvider example

```ts

@Module({

  controllers: [CatsController],

  providers: [

    ProviderHelper.createClassProvider('ICatService', CatService),

    ProviderHelper.createClassProvider('ICatRepository', CatRepository),

  ],

})

export class CatsModule {}

```

### FactoryProvider example

```ts

@Module({

  controllers: [CatsController],

  providers: [

    ProviderHelper.createClassProvider('ICatRepository', CatRepository),

    ProviderHelper.createFactoryProvider(

      'ICatService',

      (ICatRepository: catRepository) => new CatService(catRepository),

      ['ICatRepository']

    ),

  ],

})

export class CatsModule {}

```
