Learn Angularjs, Lighthouse and Nativescript

Angular is a development platform for creating applications using modern web standards. Angular includes a wealth of essential features such as mobile gestures, animations, filtering, routing, data binding, security, internationalization, and beautiful UI components. It's extremely modular, lightweight, and easy to learn.

When migrating AngularJS (v1.x) applications to Angular you [have different options](https://github.com/angular/ngMigration-Forum/wiki/Migration-Paths-Overview). Using Angular Elements is one of them. In this lesson we learn how to integrate an Angular Element into an AngularJS (v1.x) application. We will leverage some features release in the latest AngularJS 1.7.3 that make it fully compatible with custom elements.

Many times while building an AngularJS application you'll need to manipulate data, and it doesn't make sense to do it with a Controller method. Luckily you have Filters, which are particularly well suited for manipulating text within your HTML views. This handy tool uses a simple syntax to create highly reusable functionality for your apps.

Manually creating action items every time we need to dispatch an action eventually accumulates to a very tedious process. In this lesson, we will learn how to abstract out the creation of action items so that we consolidate their creation into a single place. This not only creates efficiencies in how we express code but also reduces code volume while simultaneously increasing stability. 

Angular 1.x Redux: Create Reusable Actions with Action Creators

In this lesson, we are going to learn how to enable our store to work with more than one reducer in an application.

Currently, we have set up our store to work with the categories reducer exclusively, but this leaves us with a real problem, what if we want to keep track of the currently selected category within our store so that we can access that data somewhere else in the app? It is safe to say that most applications consist of many data models interacting together, and we need a way to accommodate this within the single state tree in our application.

When we initialize our app store, wouldn't it be convenient if we could take all of our reducers and combine them into one big reducer that our store knows how to work with? Well, this is exactly what the combine reducer method does in Redux. It allows us to combine reducers together and then access them as a named property on our application store.

We currently have a category reducer just hanging out here doing nothing because we have been focusing entirely on the categories reducer. We are going to combine the two reducers so that we can use the current category data within our bookmarks component.

Angular 1.x Redux: Handle Multiple Models by Combining Reducers

Invariably the question that comes up when talking about Redux is how does one handle asynchronous operations in redux. For instance, how do we hand off an operation to redux that requires a remote call to the server? Where exactly does the async part get handled? 

Redux has this concept of middleware that allows us to insert custom logic in the space between dispatching an action, and the moment it reaches the reducer. In this lesson, we are going to set up a few async operations and then use redux thunk middleware to make sure that everything makes it into the reducer properly.

The main key to thunk middleware is that it allows us to return a function instead of an action. This function can encapsulate the async operation and dispatches the appropriate action when the operation is completed.

Angular 1.x Redux: Handle Asynchronous Operations with Middleware

One of the primary advantages of using redux is that reducers are incredibly easy to test. By nature, they have a clearly defined contract of inputs and outputs, and because they are stateless, they require very little instrumentation to test in isolation. 

We will start with a few simple tests for the categories reducer and then move on to testing the CRUD functionality within the bookmarks reducer. 

Angular 1.x Redux: Test Reducers

Up to this point, we have created an effective, yet rudimentary, implementation of Redux by manually creating an application store, reducers and action creators. We have already made significant progress in simplifying state management within our application, but we have in fact only touched the surface of what Redux has to offer.

In this lesson, we are going to introduce ngRedux into our application and let it handle the rest of the heavy lifting as we work through this series. ngRedux is a project that provides angular bindings to redux to streamline integrating it into our application.

Angular 1.x Redux: Integrate ngRedux

In this lesson, we are going to learn how to integrate Redux Devtools into our Angular application.

Redux Devtools is a live-editing time travel environment for Redux. Devtools boasts a list of awesome features but my two favorite ones are that we can inspect every state and action as it happens and we can go back in time by “cancelling” actions.

This is going to be an interesting lesson because, in order for this to work, we are going to need to make something that was written for React work in Angular. For the most part, everything will play side by side with one small trick that we will pull off at the end to force an Angular digest cycle when React manipulates the application store. 

Angular 1.x Redux: Integrate Redux Devtools

One of the biggest mental shifts that developers have to take when embracing redux is shifting from mutable operations to immutable operations. The problem with mutable operations is that they create side effects that involve anything else that is referencing the thing that is being mutated.

With immutable operations within a reducer, a new object is returned for every operation – completely bypassing the possibility that an existing reference is going to be compromised. It is then up to the consumer to decide how they want to get the new data and what to do with it.

In this lesson, we are going to flesh out the CRUD functionality of our bookmarks reducer, doing it first using mutable operations and then refactoring it to use immutable operations.

Angular 1.x Redux: Avoid State Mutation with Immutable Operations

In this lesson, we are going are going to apply everything that we have learned by building out our bookmarks component to be powered by Redux. This will help reinforce all the techniques we have covered by seeing them built out  in a single, contiguous lesson.

We will walk through the steps necessary to phase out the bookmarks model with a Redux implementation that includes building and integrating the equivalent reducers and action creators to integrate into our application.

Angular 1.x Redux: Put It All Together

In this lesson, we are going to learn how to map our Angular component directly to our application store using the connect method on ngRedux. 

In Angular, it is a common technique to bind a controller property directly to the model so that our controllers remain lightweight and operate more as a pass through mechanism than anything else.

Using the connect method, we can accomplish the same effect by not only binding properties directly to the application store, but also binding our controller to our action creators. This allows us to drastically simplify our controllers as we are able to delete a bunch of local controller methods as they become unnecessary because of our mappings.

Angular 1.x Redux: Map State and Dispatchers to Redux

In this lesson, we are going to extend our application store with a subscribe method so that we do not have to manually query our application store every time we dispatch an action.

In our categories controller, we are dispatching a **GET_CATEGORIES** action every time we want to update the categories collection within our application store. For this change to be propagated back into our controller, we need to call **store.getState**. 

Depending on how many times we are calling **store.dispatch**, this could get very cumbersome. We will extend our application by adding a subscribe method so that state changes are automatically pushed into our controller.

Angular 1.x Redux: Subscribe to the Application Store

In this lesson, we are are going to learn how to abstract out state mutations into a reducer. In our current Eggly application, all of the state and business logic for our categories is handled within the categories model. We are going to refactor our code to entirely eliminate the need for our categories model by building out a couple of reducers and seeing how we can interact with them directly. 
The key thing to notice as we build out our reducers is that a reducer itself is completely stateless because it receives current state every single time it needs to calculate and return the new state. With a clearly defined contract of inputs and outputs, this makes testing reducers really easy which is one of the huge benefits of using this approach. 

Angular 1.x Redux: Handle State Mutations with Reducers

In this lesson, we are going to learn how to build an application store so that we can have a single place to store our application state. Reducers are great for updating state because they are stateless, but they are very bad at preserving state, which is vital when you need to reference state in more than one place.

We will build out a simple application store that will be responsible for keeping track of our categories collection that our categories controller can consume.

Angular 1.x Redux: Persist State with an Application Store

Speed up your bug-fixing process dramatically with Cursors Composer. Take a warning from your logs, search for relevant terms, then seamlessly import both the warning and search results into Composer. Add documentation and apply fixes to all search results in one go. This streamlined workflow resolves multiple issues rapidly, saving valuable development time.

You know when you're deep in the code trenches and need someone to challenge your assumptions? That's exactly what this is about.

Instead of waiting for someone to poke holes in your master plan, you can paste that strategy straight into AI Studio and let it pressure test your ideas. We're talking about using this tool to validate everything from your feature proposals to your ambitious refactoring strategies.

The real magic happens when you hit that microphone button. Now you're in a real-time verbal sparring match. It's like rubber duck debugging but the duck actually pushes back and makes you defend every architectural decision you've made.

Here's the workflow:
1. Drop your master plan into the system instructions
2. Tell the AI to challenge every assumption
3. Hit that mic and defend your choices like you mean it
4. Watch your plan either emerge stronger or get rightfully dismantled

This approach is perfect when you're:
- Stuck in your own head with a complex problem
- Need to validate if your approach holds water
- Want to catch edge cases before they catch you
- Looking for opportunities you might have missed because you're too close to the code

It's like having a senior dev on call 24/7, ready to challenge your ideas and push you to think deeper about your solutions.

Now go forth and get your ideas challenged. Your projects will thank you for it.


An Uncomfortable and Challenging Conversation with AI Studio

In this lesson, you'll learn how to effectively brainstorm your project ideas before working with AI agents. We'll cover:

1. The importance of having a clear plan before starting work with AI agents
2. Using traditional brainstorming techniques to gather your thoughts
3. Leveraging video recording to capture your brainstorming session
4. How to review and analyze websites for inspiration
5. Documenting likes, dislikes, and potential features for your project
6. Using AI tools (like AI Studio) to organize and process your recorded brainstorming session

The lesson emphasizes a modern approach to brainstorming that combines traditional techniques with video recording, making it easier to later process your ideas through AI tools. This method helps ensure that no ideas are lost and that your thoughts can be effectively organized by AI for future reference.

How to Brainstorm Your Project Features to Prepare for AI Agents

Many people share .cursorrules files, but trying to craft your own from scratch is a huge pain. Instead, this lesson shows you how to grab ALL community-created .cursorrules files to build a custom rule set for your projects. We'll use Gitingest and Google AI Studio to gather these examples and generate an awesome starting point customized to your specific project.

Generate Custom .cursorrules for Your Project Based on Community Examples

The GitHub CLI allows you to search issues and filter on different criteria like amount of comments. This allows you to search for real-world situations and pains/solutions people have using different technology. 

With the GitHub CLI in hand we'll drop 100s of issues as context in Googles AI Studio and have Gemini determine the 10 most frequently asked questions. This will give us a sense of how people use a library and where people get hung up.

Search 100s of Issues with GitHub CLI as Context for AI Studio

I often find myself wondering how to use certain APIs in certain situations, and I have a couple of keywords that I try and search up on Google. 

What you can do in this situation is turn to GitHub and see how other people have actually used this code on public projects. The GitHub CLI enables us to run searches like this, and we can take the results and work on them programmatically.

Inside of Cursor with their Composer AI agent, we can search for the files we want, tell the agent to download them, and inspect them for better understanding of how those things work together.

Implement virtual scrolling to handle large datasets in an HTML table. Start with a basic table that renders 10,000 rows of data. The browser can struggle with this amount of DOM nodes to render at one time, especially on low end devices. 

We implement tanstack react virtual to render only the necessary amount of rows the user is viewing. The implementation includes proper column sizing, accessibility considerations, and convenient scroll controls, resulting in a smooth and performant table experience regardless of the dataset size.

Learn how to implement virtual scrolling in React tables using TanStack Table and Tanstack Virtual with the useWindowVirtualizer React hook.

The most difficult tasks will require the strongest AI models. And those models simply aren't available as AI agents inside of your tooling. So the best workflows are to drag and drop the files you need to be changed and analyzed inside of a reasoning model such as OpenAI's O1 Pro, then letting it create a giant plan for your dumber AI agents to work on. The key here is that instead of just copying and pasting the entire plan into Cursors Composer or your AI agent, it's to create a file inside of your project and ask your agent to tackle the plan one step at a time. This allows you ample opportunity between each step to test and verify the micro steps along the way. Otherwise, as I've experienced many times, a session can go way off track and you burn a lot of time and burn a lot of AI requests Cursors Composer and it starts churning through a plan Cursors Composer and making lots of unwanted changes. Cursors Composer and it's to guide an AI agent to hold its hand along the way, especially through the most complex tasks. Cursors Composer and the most complex tasks Cursors Composer and the most complex tasks require a step-by-step plan.
