+### Module
+
+> Use Module to resolve modules exports, import modules using hrefs' ensuring compatibility between OS's, creating
+> aliases for your modules exports and creating __filename and __dirname properties.

+```ts
+import { Module } from '@secjs/utils'
+
+const module = await Module.get(import('#src/Helpers/Options'))
+
+console.log(module.name) // Options

+
+const modules = await Module.getAll([import('#src/Helpers/Number'), import('#src/Helpers/Options')])
+
+console.log(modules[0].name) // Number
+console.log(modules[1].name) // Options
+```
+
