 Many of the utilities provided by Powertools for AWS Lambda (TypeScript) can be used with different programming paradigms:
 
-- **Middy** middleware. It is the best choice if your existing code base relies on the [Middy 4.x](https://middy.js.org/docs/) middleware engine. Powertools for AWS Lambda (TypeScript) offers compatible Middy middleware to make this integration seamless.

 - **Method decorator**. Use [TypeScript method decorators](https://www.typescriptlang.org/docs/handbook/decorators.html#method-decorators) if you prefer writing your business logic using [TypeScript Classes](https://www.typescriptlang.org/docs/handbook/classes.html). If you aren’t using Classes, this requires the most significant refactoring.
 - **Manually**. It provides the most granular control. It’s the most verbose approach, with the added benefit of no additional dependency and no refactoring to TypeScript Classes.
