Deploying an Angular app to AWS when merging to the master branch on GitHub involves several steps, including setting up AWS services, configuring GitHub Actions, and creating deployment scripts. Here's a general overview of the process:

1. Set Up AWS Services:

   a. S3 Bucket: Create an Amazon S3 bucket to store your Angular app's static files (HTML, CSS, JS).

   b. CloudFront Distribution (Optional): Set up an Amazon CloudFront distribution to serve your app's content globally for better performance.

2. Configure AWS Credentials:

   a. Create an IAM user with appropriate permissions (S3, CloudFront if used).

   b. Generate AWS Access Key and Secret Access Key for the IAM user.

   c. Configure these credentials on your local machine or your CI/CD environment where the deployment will take place. This can be done using environment variables or AWS CLI configuration.

3. Set Up GitHub Actions:

   a. In your Angular project repository on GitHub, create a .github/workflows directory.

   b. Create a YAML file (e.g., deploy.yml) in this directory to define the GitHub Actions workflow.

   c. Configure the workflow to trigger on merges to the master branch.

4. Define Deployment Steps:

   a. Within the workflow file, define steps to build and deploy the Angular app:

I came up with a brainstorming app and I built it with MERN. Like MEAN but with React instead of Angular. 

MERN is an acronym that stands for MongoDB, Express.js, React, and Node.js. It refers to a popular stack of technologies used for building modern web applications. Each component of the MERN stack represents a different layer of the application's architecture and contributes to the overall development process.

Here's an overview of each technology in the MERN stack:

MongoDB: MongoDB is a NoSQL database that stores data in a flexible, JSON-like format called BSON. It is known for its scalability, flexibility, and ability to handle large volumes of data. MongoDB is often used to store the application's data and provides a convenient way to interact with structured and unstructured data.

Express.js: Express.js is a web application framework for Node.js. It simplifies the process of building robust and scalable server-side applications. Express.js provides a set of tools and middleware to handle routing, request handling, and other common tasks, making it easier to create APIs and handle server-side logic.

React: React is a JavaScript library for building user interfaces. It focuses on creating dynamic and interactive user interfaces by using a component-based approach. React allows developers to build reusable UI components that efficiently update and render based on changes in application state. It is commonly used for creating the client-side of web applications.

Node.js: Node.js is a server-side runtime environment that allows developers to build scalable and event-driven applications using JavaScript. Node.js provides a non-blocking, asynchronous architecture, making it well-suited for handling I/O-heavy tasks and building APIs.

I have been learning the Vue framework and I discovered that Element UI is the go to CSS framework for working with Vue. 

Element UI is a popular open-source UI framework for building responsive and customizable web applications. It is designed to work with Vue.js, a progressive JavaScript framework, and provides a set of high-quality components and features to streamline the development of modern user interfaces.

The 12-Factor App methodology is a set of best practices and principles designed to guide the development and deployment of modern cloud-native applications, including microservices. These principles were formulated by developers at Heroku (a cloud platform) and have been widely adopted by the software industry as a foundation for building scalable, maintainable, and portable applications. The 12 factors provide a clear set of guidelines for building applications that can take full advantage of modern cloud environments and enable efficient development, deployment, and scaling.

Here are the 12 factors of the 12-Factor App methodology:

Codebase: Maintain a single codebase for your application, versioned in a source code control system.

Dependencies: Explicitly declare and isolate dependencies. Use a package manager to manage dependencies.

Configuration: Store configuration settings in the environment, separate from the codebase. Configuration should not be hard-coded.

Backing Services: Treat external services (databases, caches, queues, etc.) as attached resources. Connect to them via URLs or credentials stored in configuration.

Build, Release, Run: Separate the build, release, and run stages of your application. Keep builds and releases repeatable and independent.

Processes: Run your application as one or more stateless and share-nothing processes. This facilitates scalability and fault tolerance.

Port Binding: Export services via a well-defined port and listen for connections on that port.

Concurrency: Scale out your application by adding more processes rather than making individual processes larger.

Disposability: Design your application to be disposable, meaning it can start and stop quickly without affecting the overall system.

Dev/Prod Parity: Keep development, staging, and production environments as similar as possible to reduce the likelihood of bugs and issues.

I was studying the Vue framework today and I put together this little sample app to demonstrate the basics of Vue components and Pinia state management.  Pinia is kinda like Redux for Vue. 

Pinia is a state management system for Vue.js applications. It provides a modern and ergonomic way to manage application state in Vue applications, and it is designed to work seamlessly with the Vue ecosystem. Pinia takes inspiration from concepts in modern state management libraries while focusing on simplicity, performance, and ease of use.

Key features and concepts of Pinia include:

Stores: Pinia introduces the concept of "stores," which are modules that encapsulate a specific piece of application state and its related actions (mutations and actions). Each store represents a distinct area of your application's data and logic.

Reactivity: Pinia leverages Vue's reactivity system, ensuring that changes to store state are automatically reflected in the UI components that depend on that state. This allows you to build reactive and responsive user interfaces.

Composition API: Pinia encourages the use of Vue's Composition API, which provides a more flexible and expressive way to structure component logic. This allows you to create stores using the Composition API's setup function.

Typescript Support: Pinia is designed with TypeScript support in mind. It provides strong typing for stores and their methods, helping you catch type-related errors during development.

Separation of Concerns: Pinia encourages a clear separation of concerns by grouping related state and logic within individual stores. This promotes a modular and maintainable codebase.

Devtools Integration: Pinia integrates with Vue Devtools, making it easier to inspect and debug your store's state and actions.

Plugin System: Pinia supports plugins that can extend its functionality, allowing you to add features or integrations to your stores.

Express is a popular and widely used web application framework for Node.js. It simplifies the process of building robust, scalable, and efficient web applications and APIs by providing a set of features, utilities, and tools that streamline common tasks involved in web development.

Key features and characteristics of Express include:

I created this example table of NgRx built with Angular and Material.

Let's walk through a simple example of how NgRx can be used to manage the state of a counter in an Angular application.

1. Setup: First, make sure you have Angular CLI installed. You can create a new Angular application using the following command:

2. Install NgRx: Navigate to the project directory and install the necessary NgRx packages:

NgRx is a state management library for Angular applications. It is built on top of the Redux pattern, which is a predictable state container for managing application state in a consistent and scalable way. NgRx extends the Redux pattern to work seamlessly with Angular's components, services, and other features.

The core concepts of NgRx include:

1. Store: The central repository for managing the state of an Angular application. It holds the entire application state, and components can subscribe to changes in the store to receive updates.

2. Actions: These are plain JavaScript objects that describe an event that has occurred in the application. Actions are dispatched to the store to trigger state changes.

3. Reducers: Reducers are pure functions responsible for transforming the current state and an action into a new state. They specify how the application's state changes in response to different actions.

4. Effects: Effects provide a way to manage side effects, such as making API calls, updating the database, or navigating to a different route. Effects listen for specific actions and then perform asynchronous tasks.

5. Selectors: Selectors are functions that retrieve specific pieces of data from the store. They allow components to efficiently access and subscribe to only the relevant parts of the state.

By using NgRx, developers can maintain a clear separation of concerns between components, state management, and side effects. This can lead to more maintainable, testable, and scalable Angular applications.

It's worth noting that while NgRx is a powerful tool for managing state in Angular applications, it also introduces some additional complexity. Developers should carefully consider whether the use of NgRx is appropriate for their project's size and requirements.
