12 Factor App Microservices

Overview:

This analysis focuses on a NestJS application that serves as a starter repository for implementing the 12 Factor App methodology in a Node.js environment, specifically on cloud.gov. It aims to showcase the implementation of best practices such as tracking codebase in revision control, managing dependencies, storing configuration in environment variables, treating backing services as attached resources, and more.

Features:

• Baseline: Provides a starting point for implementing the 12 Factor App methodology in a NestJS application.
• Lint & Test Configurations: Includes configurations for linting and testing the application.
• Migration Setup: Setup for migrating data and codebase.
• Unit & Integration Test Setup: Configurations for setting up unit and integration testing.
• Pin Down NPM Package Versions with Yarn.lock: Ensures specific versions of NPM packages are locked down.
• Manage Configuration Values with Environment Variables: Demonstrates storing configuration values in environment variables.
• Build, Release and Run Containers with Docker Compose: Guidelines for building and running containers using Docker Compose.

Summary:

The NestJS application discussed serves as a resource for developers looking to follow the 12 Factor App methodology in their Node.js projects. By providing guidance on aspects such as tracking codebase, managing dependencies, storing configurations, and utilizing Docker for containerization, the application exemplifies best practices for developing scalable and maintainable cloud-native applications.
