Nestjs Bff

Overview:

NestJS-BFF is a full-stack TypeScript solution and starter project that aims to fast-track the development of enterprise-grade, modern NodeJs applications. It follows the Backend for Frontend (BFF) pattern, using NestJS as the primary framework for the backend. The frontend example is built with Angular, but it can be easily adapted to work with other client-side JavaScript frameworks like React or Vue.js. The project is designed as a mono-repo, containing a Backend, companion CLI, Frontend, and companion NPM packages. The core infrastructure is contained in NPM packages for easy updates through a simple NPM update command.

Features:

• Strongly Typed backend: Leveraging the power of TypeScript, NestJS, and Express, the backend is strongly typed, ensuring a more robust and maintainable codebase.
• DDD style layered architecture: The project follows a Domain-Driven Design (DDD) style layered architecture with Application Services and composable Domain objects, promoting clean separation of concerns.
• Comprehensive authentication and authorization system: The library provides an in-the-box authentication and authorization system. It includes JWT authentication for robust and flexible security, as well as social login with Facebook (complete), Google, and Twitter (under development) using the Authorization Code Grant flow.
• Secured-by-default with 'allow list' approach: The project follows a 'allow list' approach for security, ensuring that only explicitly permitted actions are allowed. This helps to prevent potential security vulnerabilities.
• Flexible Caching: Leveraging the powerful cache-manager library, NestJS-BFF provides flexible caching options to improve performance and reduce database load.
• Repository Pattern: The library includes the Repository Pattern out-of-the-box for simple data access.
• MongoDB Migrations: NestJS-BFF provides easy database seeding and management through MongoDB Migrations.
• Winston and Console Logger Service: The library includes a Winston and Console Logger Service, making it easy to log and manage application logs.
• Configuration pattern: The project follows a simple and strongly typed configuration pattern, making it easier to manage and update configurations.
• e2e Testing pattern leveraging Jest: The project includes an e2e testing pattern that leverages Jest, making it easier to write and run end-to-end tests.

Summary:

NestJS-BFF is a powerful full-stack TypeScript solution and starter project that aims to accelerate the development of enterprise-grade NodeJS applications. It follows a layered architecture, provides comprehensive authentication and authorization features, and includes various other features like caching, logging, and database management. With its strong typing and support for popular frameworks like Angular, NestJS-BFF offers a compelling web development stack. Although the library is currently not actively maintained, it can still serve as a valuable reference for building production-ready apps using NestJS.
