Learn Angularjs, P5 and Script-kit

How often do you avoid scripting something because it takes too much effort?\n\nScript Kit makes it easy to create and run scripts that solve your daily problems. Create a new script from the prompt then your script opens in the editor of your choice. Write a few lines of JavaScript. Then run the script from the prompt.\n\nSimply put, Script Kit helps you script away the friction of your day.

Create, read, update, delete. Four actions that every developer becomes intimately familiar with over their career. Script Kit aims to make this process as pleasant as possible using a `db` helper and what better way to show it off than a Todos app?

You will also learn how to create and switch between tabs through Script Kit's `onTab` and `setTab` methods. 

[Install todos](https://scriptkit.com/api/new?name=todos&url=https://gist.githubusercontent.com/johnlindquist/3bdc967ffbd2f6d72491d07bf720f7e2/raw/a37b0058b502d6ba4bebd7a31a30be8789f5a146/todos.js")

let { todos, write } = await db({ todos: [] })

onTab("Todos", async () => {
  while (true) {
    let todo = await arg("Toggle todo:", todos)
    let t = _.find(todos, todo)
    t.tag = t.tag === "open" ? "done" : "open"
    await write()
  }
})

When you want to collect news sources, airline ticket prices, or any events from sites that don't offer APIs, you can use scrapers to grab elements from off the page. 

Script Kit includes a `scrapeSelector()` helper that takes the URL you want to scrape and the selector you want from the page. Using the `// Schedule` metadata, you can also have this script run in the background on a Chron schedule and collect the data for you.


[Install scrape-tech-news](https://scriptkit.com/api/new?name=scrape-tech-news&url=https://gist.githubusercontent.com/johnlindquist/acd397a2ed487ef2a06c00d2951bed63/raw/3942107d2c92abc2c0317d15b0b3d025c5643ef0/scrape-tech-news.js")

We put a lot of work into browsing the internet every day, it would be a pity to lose it all by closing all of our tabs. 

Script Kit can collect all of the tabs you currently have open in Chrome using its `getTabs` method and store them anywhere you want. 

This particular script converts the tabs to markdown links and stores them in a text file on your file system, but you could convert and store them using any approach you can think of.


[Install save-tabs](https://scriptkit.com/api/new?name=save-tabs&url=https://gist.githubusercontent.com/johnlindquist/4713a161a9ec48932b05436ba6a1a123/raw/33f753586d1a158dfb69d07f29850b6013d59f8b/save-tabs.js")

Sometimes you just want to select and modify some text you have written somewhere on your system. To help you with this, Script Kit provides a `getSelectedText` and `setSelectedText`. Between these two helpers, your script and use and/or modify the text however you want. 

Applying an npm tool like `title-case` can help when you're not entirely sure when certain words need to be capitalized. In fact, I used the title case script on the title of this lesson!

[Install title-case](https://scriptkit.com/api/new?name=title-case&url=https://gist.githubusercontent.com/johnlindquist/0f8323d6aa599cfd62034351f9d38e8c/raw/625d0afd57ccbf8bf64c62bd135474cecf98c58b/title-case.js")

```js
// Name: Title Case

import "@johnlindquist/kit"

let { titleCase } = await npm("title-case")

let selectedText = await getSelectedText()
let titleText = titleCase(selectedText)

await setSelectedText(titleText)

// This Is the Title of My Next Blog Post
```

Chrome allows developers to execute JavaScript using Apple Events. When you enable this feature, you can write scripts that can access and modify the page you're currently browsing. 

You can get the site's contents, update storage, or do any action you would typically do through an extension of the Chrome Dev Tools.

```jsx
let value = await applescript(`
tell application "Google Chrome" to tell window 1
	get execute active tab javascript "

${js}

"
end tell
`)
```

Control Chrome From Script Kit using Apple Events

Many developers use Chrome's Dev Tools as a playground for testing out data and JavaScript features. Script Kit enables you to launch Chrome Dev Tools instantly by simply using the `dev` method. Any data you pass into `dev` will show up in the console so you can inspect and play with the data in any way that you want.

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.

Use Angular components in AngularJS applications with Angular Elements

AngularJS is an open-source JavaScript framework, maintained by Google, that assists with running single-page applications. Its goal is to augment web-based applications with model–view–controller (MVC) capability, in an effort to make both development and testing easier.

angularjs

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.

Filters

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

Up and Running with Tanstack Router and React

Learn TanStack Router for React: set up apps, use file-based routing, manage routes, and boost app performance.


In this lesson, we explore how TanStack Router integrates with the [native browser history API](https://developer.mozilla.org/en-US/docs/Web/API/History) to manage navigation.

As we navigate through different routes, the URL changes are stored in the browser's history, allowing users to use the forward and backward buttons to traverse their navigation history.

This functionality also **enables permalinks**, meaning users can copy and paste URLs to access specific routes directly.

Additionally, we learn how to programmatically interact with the history object to move forward or backward through the navigation stack, enhancing the user experience by providing full control over navigation actions.

This compatibility with the native history API ensures that TanStack Router applications behave similarly to traditional websites, offering a seamless and intuitive user experience.

In this lesson, we explore how to hook into TanStack Router's lifecycle hooks to execute custom logic during route changes.

The hooks we'll look into are: `onEnter`, `onStay`, and `onLeave`, which are triggered when entering, staying within, or leaving a route, respectively.

All hooks receive a detailed match parameter, providing information about the route's path, ID, and tons of other details.

This allows for the implementation of features like animations or logging when navigating between routes.

We also learn how to use these hooks to track and manage state changes as users interact with the application, making it easier to implement complex behaviors based on route transitions.

Hook into Route Lifecycle Hooks in Tanstack Router

Hook into TanStack React Router's lifecycle hooks for custom route logic and animations.

In this lesson, we learn how to handle not found errors in TanStack Router by using the `notFoundComponent` at both nested and global levels.

To trigger the display of a `notFoundComponent`, we must throw a specific error using the `notFound` function within a loader or other lifecycle method of a route. This approach allows us to provide custom error messages for specific routes or globally across the application.

We explore how to define a notFoundComponent within a specific route's configuration and how to set a `defaultNotFoundComponent` at the router global level, which applies to all routes unless overridden locally. This flexibility ensures that users receive meaningful feedback when encountering non-existent routes.

Provide NotFoundComponent at Nested Route or Global Level in Tanstack Router

Handle notFound errors in TanStack Router with notFoundComponent at nested or global levels.



In this lesson, we learn how to access dynamic route parameters using the `useParams` hook in TanStack Router.

When used with a specific `Route` object, `useParams` provides type-safe access to route parameters, ensuring that TypeScript knows the exact types of these parameters.

This approach eliminates the possibility of undefined/optional values, making it safer for accessing parameters like `employeeId`.

However, when using `useParams` globally without specifying a route, it requires an options object with `{ strict: false }`, which reduces type safety.

In this case, the hook can access parameters from any route in the application, but it does not guarantee their existence or type. This flexibility allows components to be reused across different routes, but it requires careful handling of potential errors.



Access Dynamic Route Parameters with useParams in Tanstack Router

In this lesson, we learn how to reorganize file-based routes in TanStack Router to accommodate nested routing structures.

We explore how to create additional nested routes by converting files into directories, allowing for further nesting.

For example, to create a nested route like `/employees/$employeeId/edit`, we can create a **directory** (!) named `$employeeId` and place an `index.tsx` file inside it to define the route component for this nested route.

This approach provides flexibility in organizing files while maintaining the convention that file names and locations align with route paths. We also see how to adapt existing components and loaders to work with these reorganized routes, enabling features like edit forms or delete actions (or whatever) within nested routes.


Reorganize File-Based Routes in Tanstack Router

Reorganize file-based routes in TanStack Router for flexible nested routing.



In this lesson, we learn how to parametrize the loader for a nested route in TanStack Router.

We focus on a nested route like `/employees/$employeeId`, where the `$employeeId` is a **dynamic parameter**.

To fetch data for this route, we use a `loader` function that accesses the `$employeeId` parameter. This is achieved by using the params object available in the `loader` function, which contains the dynamic segments of the URL. We then use this parameter to call a function like `getEmployeeById`, which fetches specific employee details from an API.

We highlights that TanStack Router **automatically infers types** for these parameters, ensuring type safety for nested routes.

Parametrize Route Loader for Nested Route in Tanstack Router

In this lesson, we learn how to create nested routes and outlets in TanStack Router using file-based routing.

We start by creating a new `employees` directory and files to represent nested routes, such as `/employees/$employeeId`. The `$` symbol is used to denote dynamic parameters.

We then use the `<Link>` component from TanStack Router to create links to these nested routes, passing necessary parameters.

To render the nested content, we use the `<Outlet>` component (nested), which automatically renders child routes. This approach allows us to dynamically display stuff under a nested route.

All the time, the TanStack Router generator automatically updates the route tree based on file changes - our routing configuration remains consistent 🔥
