Learn using Shoulder.dev

Shoulder.dev transforms codebases into tailored learning experiences. Below are organized categories of the codebase to help you start with your initial focus.

Docker Basics

Learn the fundamental concepts of Docker, including containers, images, and Dockerfile syntax. This is crucial for understanding the entire project.

Docker Compose

This topic focuses on using Docker Compose to define and manage multi-container applications. It helps simplify the process of running and scaling the application.

Container Networking

Explore how to connect containers together and establish communication between them. This is important for multi-container applications.

Docker Volumes and Bind Mounts

Understand the difference between volumes and bind mounts and how they are used for data persistence and development purposes.

Image Layer Caching

Learn how Docker leverages image layer caching to optimize build times and reduce image size.

Multi-stage Builds

Dive into multi-stage builds, a powerful technique for separating build-time dependencies from runtime dependencies. This is essential for creating efficient images.

Node.js Web Application

This topic focuses on the application itself, which is built using Node.js and Express. Explore its code structure and how it handles routing and data persistence.

React Frontend

Learn about the React front-end used in the application. This includes its components, state management, and interaction with the Node.js backend.

Testing and Debugging

This topic is vital for ensuring application quality. Explore the unit tests written in the project, how they are run, and how to debug issues.

CI/CD

Understand the continuous integration and continuous delivery (CI/CD) workflow implemented using GitHub Actions. This helps automate builds, tests, and deployments.

Security

Explore the security aspects of the codebase. This could include topics like container security best practices, dependency vulnerabilities, and secure coding practices.

MkDocs Documentation

Learn how to use MkDocs to generate documentation for the project. This allows you to understand the project structure and features.

Bash Scripting

Analyze the build.sh script, understanding its role in the build process and how it uses Bash commands.

Version Control

Learn how to effectively use Git to manage the codebase, including committing changes, branching, and collaborating with others.
