Authentication and authorization in NestJS
Authentication and authorization are critical components of any secure application, determining who can access your system and what they are permitted to do once inside. In previous chapters, we delved into implementing these mechanisms within various contexts, such as securing GraphQL APIs and protecting user data in an e-commerce application.
