Implementing authentication with hooks
We’ve already utilized Fastify plugins to organize routes and enhance the maintainability of our project, but these are just some of the advantages that the Fastify plugin system provides. The key features of the plugin system are as follows:
- Encapsulation: All the hooks, plugins, and decorators added to a plugin are bound to the plugin context, ensuring they remain encapsulated within the plugin’s scope.
