+/**
+ * ### constructor
+ * 
+ * The constructor allows you to access resources from the module's container using the first parameter,
+ * and the module's options using the second parameter.
+ * 
+ * If you're creating a client or establishing a connection with a third-party service, do it in the constructor.
+ * 
+ * #### Example
+ * 
+ * ```ts
+ * import { Logger } from "@medusajs/types"
+ * import { AbstractFileProviderService } from "@medusajs/utils"
+ * 
+ * type InjectedDependencies = {
+ *   logger: Logger
+ * }
+ * 
+ * type Options = {
+ *   apiKey: string
+ * }
+ * 
+ * class MyFileProviderService extends AbstractFileProviderService {
+ *   protected logger_: Logger
+ *   protected options_: Options
+ *   // assuming you're initializing a client
+ *   protected client
+ * 
+ *   constructor (
+ *     { logger }: InjectedDependencies,
+ *     options: Options

+ *     // assuming you're initializing a client
