Using a GitHub repo to deploy our application to Vercel, keeps our code and live production site in sync. In this lesson we look at using the [GitHub CLI](https://cli.github.com/) tool to create a public repo, and adding it as a remote origin for our project.

Additionally, we create a new Vercel project from this GitHub repo, add our Supabase environment variables, and deploy. Lastly, we update the Homepage URL in our GitHub OAuth app to be our new Vercel URL, and set our Supabase project's [Authentication Site URL](https://app.supabase.com/project/_/auth/url-configuration) to our new live application URL.

## Extension ideas

- Style the app using Tailwind CSS (or another method of choice)
- Implement the ability for a user to `update` and `delete` their own messages
- Add the option to set a username and display this alongside messages
- Add separate message threads/chat rooms
- Implement private messages/chat rooms

Vue (pronounced /vjuː/, like view) is a progressive framework for building user interfaces. Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adoptable. The core library is focused on the view layer only, and is very easy to pick up and integrate with other libraries or existing projects. On the other hand, Vue is also perfectly capable of powering sophisticated Single-Page Applications when used in combination with modern tooling and supporting libraries.

In this video you'll learn how to use Amplify hosting to deploy a Nuxt site from a Git repository. We'll begin by walking through the steps of creating the deployment and configuring the correct build settings to enable a static build. Once the site is deployed, we'll view the live site hosted on AWS.

Deploying a Nuxt Site to AWS from a Git repository with Amplify hosting

In this video you'll learn how to deploy a static Nuxt site to AWS's global edge CDN in less than two minutes. We'll start from scratch, creating a new Nuxt site using npx and walk through the build configuration to set up the deployment target for Jamstack / static site hosting. From there, we'll initialize a new Amplify project using the Amplify CLI and walk through the settings to configure the proper build command for Amplify hosting. Finally, we'll deploy and view the live site. Once we're finished, we'll delete the project and the hosting service.

The specification describes a CSS box model optimized for user interface design. In the flex layout model, the children of a flex container can be laid out in any direction, and can “flex” their sizes, either growing to fill unused space or shrinking to avoid overflowing the parent.

With just a handful of CSS properties, we can create an intrinsically responsive photo gallery using flexbox. This is accomplished by setting our preferred width as the `flex-basis` value and allowing items to both shrink and grow. The use of `object-fit: cover` on images allows them to fully fill up the list item without distortion or overflow. We finish the gallery with a small animated effect that alters `opacity`.

Create an Automatically Responsive Flexbox Gallery

CSS Grid and Flexbox are very useful tools for providing the overall layout of a page.  I take a specific design and create the high level layout using css grid and then arrange an individual section using flex box.

Layout a webpage using css grid and flexbox

See how to use flexbox to layout variable-width content in columns, and take advantage of `justify-content` to keep flex children center-aligned on smaller viewports. We'll also learn how `margin` can be applied to resolve for lack of a well-supported `gap` property in flexbox. At the end of the lesson, we'll have styled both the "Subscribe" section and the site footer.

Use Flexbox to Responsively Layout Variable-Width Content

It's tempting to pick up a framework which has preselected flexbox or grid as the layout tool of choice, but it's important to learn when and why to use each method. This leads to slimmer stylesheets which results in better site performance, and less likelihood for "hacks" to make one method do what the other does inherently better. 

Throughout this collection, we will be progressively styling a responsive landing page template while building your knowledge on when to select grid or flexbox for any layout scenario. Spoiler alert: sometimes the best solution is using both!

Create a Landing Page with CSS Grid and Flexbox

Learn the fundamental difference between CSS grid and flexbox layout, and create utility classes for each `display` value. Then begin to apply and expand these concepts to style the landing page navigation.

We have a parent HTML element that takes up the height and width of the page. We will make that parent element into a flex container, and then vertically center its child element using `align-items: center;`. Finally, we'll use `justify-content: center;` to horizontally center the element.

Center an Element Horizontally and Vertically using Flexbox

Flexbox is a powerful way to layout HTML so that elements can grow to fit the size of their container.  It can also control how the elements are positioned within a flexed container.  

Once you start thinking in `rows` and `columns`, you can control almost any flexed layout with just a few simple flexbox layout primitives.

Get Started with Flexbox CSS Layouts

To stretch individual elements to fit the given space, we can set the `flex-grow` or `flex` attributes to any integer.  Other surrounding elements will grow proportionally to their `flex-grow` or `flex` attributes.

Proportionally Grow a Flexed Element by Setting `flex-grow` or `flex` Styles

To set the wrap settings of elements inside of a container, we can set the `flex-wrap` css attribute.  The most common values are: `nowrap`, `wrap`, or `wrap-reverse`

Wrap Elements Inside of a Flexed Container with `flex-wrap`

We changed the axis layout with 'justify-content', and the "off axis" layout is controlled by 'align-items'.  The most common values are `flex-start`, `flex-end`, or `center`.

Change the off-axis Alignment of a Flexed Container with `align-items`

We can space items inside of a flexed component in the "on-axis" direction, with `justify-content`.

Justify content can take the following values: `flex-start`, `flex-end`, `center`, `space-between`, `space-around`, or `space-evenly`

Change the Spacing of Flexed Components with justify-content

After setting `display: flex` on a parent element, you can use `flex-direction` to switch the container to be either a `row` or a `column`.

We also switch the body between `row` and `column`.

Flex into a Row or a Column with flex-direction

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.

In this lesson we will add support for deploying our application to [now.sh](https://zeit.co/now).

We will create a `now` object in package.json where we configure the name, the alias and the list of files we want to deploy.

We create an npm run-script called `now-build` and set the value to `true` to skip building the project on `now.sh`. The second run-script called `now` invokes `now deploy && now alias`. 

After this we sun `npm run build && npm run now` to build and deploy our app!

Discover how to harness the power of Cursor IDE's Composer Agent feature to optimize your code. In this lesson, you'll witness an AI agent doing all the work to generate test suites, implement performance benchmarks, and create optimized function variations - all without writing a single line of code. You'll learn how to validate performance improvements through data-driven benchmarking, ensuring that optimizations are backed by concrete metrics rather than speculation. This hands-on demonstration showcases a groundbreaking approach to automated function development that combines the precision of test-driven development with the efficiency of AI-powered optimization.


Agent-Driven Development in Cursor: Testing, Benchmarking, and Optimizing Functions

This course is aimed for using `zod` effectively in projects based on TypeScript (both browser and node.js). The benefits you gain with this course is not just simply coding, but also understanding when/why/how should you perform runtime validation.

`zod` is the missing piece to TypeScript's capabilities, which can guarantee type-safety only in compile-time.

`zod` can be used whenever the compiler cannot guarantee what happens in runtime. And... it's a very frequent usecase, such as HTTP calls, websockets, etc.

In this course you get quickly up and running by:
1. using `zod` with primitives and objects
2. adapting `zod` quickly to existing projects thanks to automatic generators
3. changing the strategy frm type-first to schema-first
4. using error-throwing `parse` or non-error-throwing `safeParse` basing on your needs
5. applying `zod` to the most common usecase - validating API responses
6. handling errors the most convenient way (out of many!)

Take advantage of runtime validation with `zod`. Take advantage of the detailed lessons in this course 🔥

Effective Runtime Type Checks with Zod


Cursor can now automatically run commands in the terminal and walk step-by-step towards building out your entire project. You give it a goal, then it will suggest the commands you need to run and the files that you need to create and you can work with it to achieve what you're building. This lesson does a quick walkthough of using a Cursor Agent to build a project from scratch and guide it along the way. Cursor Agents definitely feel like a sneak peek at the future of programming!

While using anonymous functions might seem convenient, they can create difficulties when trying to identify performance bottlenecks during profiling. This lesson will demonstrate how named functions make it easier to pinpoint and address performance issues, ultimately leading to more efficient and debuggable code. Learning this practice will greatly improve your ability to locate and fix performance issues in complex projects.

Always Name Functions in JavaScript


When attempting to load the same module twice in JavaScript you'll hit a cache and code won't re-run. In scenarios where you actually do want to have state in your modules, you'll have to use a cache-busting technique by passing a query parameter to a dynamic import. This lesson walks through how to add a query parameter, how to add the appropriate types for loading dynamic modules in TypeScript, and when these techniques are valuable.

Import the Same JavaScript Module Multiple Times with Cache Busting



The include keyword in GitHub Actions empowers you to add custom variables to your matrix strategy, providing flexibility beyond standard configurations. In this video, we'll explore how include allows you to define specific combinations of variables, enhancing control over your workflow runs. You'll see how this feature enables you to tailor jobs for unique environments or scenarios not covered by the default matrix options. By leveraging include, you can efficiently manage complex build processes with greater precision. This technique helps you streamline your CI/CD pipeline, making it more adaptable to your project's evolving needs.

Use GitHub Actions Matrix Include for Complex Job Configurations

While running `zod` schema validation agains domain-rich objects, the error message saying that _a string is not a number_ might not be really useful.

Especially, when you need to provide a meaningful feeback to the user, e.g. after they have submitted a form with lots of data.

`zod` allows to customize messages on a very granular level. We can also extract repeatable customization to `zod` error maps.

Finally, in order to process an error message further (e.g. display it to the user), we need to handle the `zod` validation errors effectively. Especially, when a big object validation has failed and we could receive a handful of errors.

That's what we learn in this lesson. 🔥

Customize zod Error Messages and Handle zod Errors Effectively

customize zod validation messages, customize zod schema property messages, reuse error maps across different schemas, navigate through zod error objects

You might want to run `zod` schema checks in different styles.

Sometimes you prefer to conditionally throw the error - that's what `parse` does. But another time you'd prefer to receive a `boolean` property that determines whether the validation was successful or not - and perform further actions accordingly.

Additionally, the error-throwing API of `parse` works extremely well with [TypeScript assertion functions](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-7.html#assertion-functions). Their combination is just... perfect! 👌

That's what we learn in this lesson.

Use parse and safeParse Runtime Type-checks with zod

use zod parse function to conditionally throw ZodError, use zod safeParse to get a boolean value and run typescript type guard over success property

In this lesson we learn that TypeScript cannot guarantee correct shapes of responses. That's due to TS performing checks in compile-time, while the response will be availbale in runtime - when TS doesn't exist anymore.

In some situations, such as HTTP requests, runtime type checks such as `zod` are essential for providing quick feedback around data-related errors.

Understand where are the possible mistakes to make while using TypeScript with HTTP calls. Use `fetch` and `axios` along with `zod` schema checks.

Also, note that similar mistakes or mistakes could happen while using web storage (e.g. `localStorage`)

Validate HTTP API Response with zod, fetch and axios

use zod as an HTTP response validation tool along with fetch and axios in order to make sure that the response has expected data structure
