Implement Passport Authentication with Local Strategy

Passport authentication

Previously, we learned to create a login endpoint and generate a JWT for authentication in NestJS. As applications grow in complexity, more sophisticated security requirements might be necessary. With various strategies, Passport offers rich features and flexibility for handling authentication challenges in more complex scenarios.

Passport is a powerful middleware that simplifies user authentication and enables various strategies for secure access control. The local strategy refers to a method of authentication where users log in using their username and password within the application.

In this lesson, we’ll learn the fundamental concepts of Passport authentication and implement a local strategy.

Passport and strategy

Passport is a popular NodeJS-based library with an active community and a wide range of authentication strategies. NestJS streamlines the integration of Passport via the @nestjs/passport module, simplifying the inclusion of Passport into the NestJS application. This module offers a decorator-based syntax for Passport, ensuring an intuitive and straightforward implementation of authentication strategies with minimal boilerplate code.

Without the @nestjs/passport module, we would ...
