Compared with the Expressjs Framework

It’s like comparing an standard car with a Luxury car. Express is a micro-framework with minimalistic features and standard HTTP server functionalities. In contrast, Nestjs is a Framework that makes use of robust HTTP Server frameworks like Express (the default) and optionally can be configured to use Fastify as well. Makes the abstraction layers, Modular Built-in Core Modules, Validations, Authentication, Authorization, and more, and more than a server framework.
