While working on a user model, I found myself navigating through best practices and diverse strategies for managing a token service, transitioning from straightforward functions to a fully-fledged, independent service equipped with handy methods. I delved into the nuances of securely storing and accessing secret tokens, discerning between what should remain private and what could be public. Additionally, I explored optimal scenarios for deploying the service or function and pondered the necessity of its existence. This article chronicles my journey, illustrating the evolution from basic implementations to a comprehensive, scalable solution through a variety of examples.
Services
In a Node.js application, services are modular, reusable components responsible for handling specific business logic or functionality, such as user authentication, data access, or third-party API integration. These services abstract away complex operations behind simple interfaces, allowing different parts of the application to interact with these functionalities without knowing the underlying details. By organizing code into services, developers achieve separation of concerns, making the application more scalable, maintainable, and easier to test. Services play a crucial role in structuring the application’s architecture, facilitating a clean separation between the application’s core logic and its interactions with databases, external services, and other application layers. I decided to show an example with JWT Service. Let’s jump to the code.
