Overview

The author of this article has created a custom template for new services based on the NestJS framework. The template includes various features to ensure that the service is ready for production deployment, such as full dockerization, coding conventions, and performance optimizations. The author clarifies that the template does not impose any specific architecture, but rather provides a starting point for customization. The article also mentions the integration of other tools like SWC for faster compilation, Fastify as the web framework for improved performance, and husky for enforcing good quality and conventions during development. The author provides code snippets and instructions for installing and using the template.

Features

• Fully dockerized service: The template provides a dockerized setup for both development and production environments, following best practices for performance and small image size.
• SWC for faster compilation: The template uses SWC, which is approximately 20 times faster than the default TypeScript compiler provided by NestJS, for compiling and running tests.
• Fastify as web framework: Instead of the default Express framework, the template integrates with Fastify, a high-performance web framework compatible with NestJS.
• Integration with husky: Husky is integrated into the template to ensure coding conventions and quality during development. It includes running a linter, using conventional commits, and automatically running tests.
• TypeScript type checking: The template checks for type errors using TypeScript to ensure code quality.
• Separation of tests from production code: The template separates unit tests from production code by having a dedicated folder for unit tests.
• Combined unit and e2e test coverage: The template allows for the combination of unit and end-to-end test coverage to provide a comprehensive view of testing.
