Learn Apollo, Graphcms and Npm

Apollo provides a universal GraphQL API on top of your existing services, so you can build new application features fast without waiting on backend changes.

We will implement the delete shop in our Nextjs application. When the user selects the delete button for a shop in the shop's list, it will execute the `DeleteShopAndProducts` mutation and delete the shop and all associated products. 

Implement Delete Shop Mutation with Apollo Client in Nextjs

Each shop will need to have products added to it by the vendor. To do this we'll need to dynamically create pages based on which shop we want to add to. Next.js has dynamically routing that we will utilize here. We'll set the shop id as the dynamic portion of the route and display a new product form. 

Here we will create that product form component and use Apollo `useMutation` like we did before to take in the form data. You'll notice a new keyword in our mutation query `connect` which we can use because we have a `@relation` set between products and shop. This connect will associate the product to the shop through the id that we grab from the route.

Create Dynamic Next.js Shop Page to Add Products for a Shop with Apollo useMutation

Next.js is a minimalistic framework for server-rendered React applications.

To make an authenticated request, we will need to get logged in users auth tokens from Auth0. Auth0 exposes a `getAccessToken` function that we can use in Next.js `getServerSideProps` to fetch the user token. It's important to note that this function can only be used server side. We'll pass that token into the page we need to send authed requests.

To enable Apollo Client to set the headers we'll extend the client so that allows us to pass in auth tokens and sets the client context. We will then destructure the client from our `useMutation` hook and set the context to include the user token.

Set Dynamic Auth Header for Apollo Client using Next.js getServerSideProps

We are ready to create new shops for our vendors. To do this we'll define a `CreateShop` mutation that will take in all the data that our form provides. Then `useMutation` will accept that mutation and give us a function to pass our data into as well as give us the new created shop data. We'll pass in user information that we get from Auth0. 

This lesson finishes up with an error because Fauna doesn't know if the request came from an authenticated user or not. We'll solve this with dynamic headers in the next lesson.

Create New Shop with Apollo Client useMutation

Now that Apollo Client is set up and ready to be used, we can finally query data from Fauna to use in our application. 

We'll go to the Fauna GraphiQL playground and copy the `findShopById` query that we ran previously. This query will be passed into Apollo's `useQuery` hook.

Query Data with GraphQL in Next.js from a Fauna Database

To build out our Shop products page on the frontend we will need data coming in from the database. To do that we need to connect Fauna to Next.js. We'll do this through Apollo Client because it will give us a lot right out of the box.

To connect our database we'll configure Apollo Client with `httpLink` and `authLink`. On the Fauna side of things we'll create a role and key for Read permissions (just Read for now) and grab the graphql endpoint to supply as environment variables for Next.js.

A Monorepo is where you have multiple projects inside a singular repository.

Introduction to Monorepos with NPM Workspaces

npm is the package manager for JavaScript. Find, share, and reuse packages of code from hundreds of thousands of developers — and assemble them in powerful new ways.

Thank you for completing my course!

You’ve learned what monorepos are, how to create them from scratch, how to install different projects inside of it, and how to run different scripts inside of a monorepo. 

So where do you go from here? I suggest creating your own Monorepo project template and publish it on Github. Take a look at Yarn Workspaces, pnpm, Learna, Nx and Turborepo for different monorepo tools. 

I also highly suggest Migrating some of your existing projects to a monorepo. Have a main frontend application that consumes a shared UI library package and a backend service. Another way would be to have a backend service, a mobile application and a frontend application. 

Best of luck and happy coding!

Intro to Monorepos with NPM Workspaces Outro

All of our applications and libraries have `test` and `typecheck` commands already written inside of them. We are able to run both the `test` and `typecheck` commands all at the same time as well. 

This has a downside. They don’t run at the same time, it’s just one after the other. To make them run at the same time, we will implement `concurrently` again.

Running Quality Checks in your Monorepo

We already have a utils package that outputs JavaScript. If we want to use that package inside any of our applications, in our case, blog or dashboard, we would have to install it first.

Share Code Between a Library and Applications Inside a Monorepo

Right now, it is not possible to run all the Dev Scripts across all the packages of the monorepo at the same time, because once we run `npm run dev` with the `-ws` flag, we will run the dev-command in the block first, but that command never ends. It is always watching for changes.

In order to run the `dev` scripts across all the packages in the monorepo, the first thing that we have to do, is to create a dev command for each one of the packages in the root package.json file. Then we can use `concurrently` to change them. We go `concurrently` and we tell it to run the utils, then the blog and then the dashboard scripts.

Run Dev Scripts for All Packages Simultaniously

We can install a dependency inside a monorepo by running npm install, then the name of the dependency, in our case, it’s going to be Lodash. But, we are going to add different flags to that.

If we use the `-w` flag, we would have to specify in what package we want to install Lodash. We will do this for `monorepo/utils`. We could also use the `-ws` flag to install Lodash across all the packages in the monorepo. We can also use `-W` in uppercase to install Lodash in the root of the project.

Install Dependencies for Specific Packages in a Monorepo

To run specific commands inside a monorepo we have to type `npm run` then the name of the command, `build`. We then add the flag `-w` for watch mode and specify which package we want to run the build command. In this case, it’s going to be the `utils` package. 

The full command will look like, `npm run build -2 @monorepo/utils`.

If you want to run all of the commands, you'll need to add the `-ws` flag. 

The full command for running all of our build commands will look like, `npm run build -ws`. 

Run App Specific Commands in a Monorepo

Creating a TypeScript library inside the monorepo is easy if we use tsup. To configure tsup, we have to set up the entry point. In our case, it's going to be the index.ts file inside the src directory.

We will also specify some extra options for tsup such as generating the types and source maps. We can also output different formats. In this case, we want to output an ESM file and a CommonJS file.

Add a TypeScript library to your Monorepo using TSUP

In order to create applications inside our monorepo, we can use different CLI tools like create-next-app or the Vite CLI. We'll install them inside the apps folder. We will create a blog and a dashboard app, one using create-next-app and the other using the Vite CLI.

It is also important to note that the only package-lock.json file that should exist, exists at the root of the project.

Install a Next.js and a Vite.js Applications Into a Monorepo

For this course, we are going to be using NPM Workspaces to configure our monorepo. We will have two workspaces, one for our apps and one for our libraries. We configure those in our package.json.

Configure NPM Workspaces in your Package.json

A monorepo is a group of small projects that can be combined to build bigger projects, or they could just be small projects that doesn't know anything about the other projects.

One great thing about monorepos is that the code is available for everyone at every time. If you are a frontend engineer, and you're working in the blog application and you see that there is a bug in the backend application, you can go and fix it right away.

What are Monorepos

In this course, Colby is going to do a deep dive into creating a full store for your products. You'll learn how to set up and use GraphCMS as your content management system. You'll learn about the Cloudinary UI extension and how to use it to host your images. You'll learn about Snipcart and using the useSnipcart hook to handle the cart state and the checkout. You'll learn how to implement Stripe as your payment gateway. And lastly, you'll learn how to deploy a Next js app to vercel from github with environment variables.

Ecommerce Product Management & Storefront with GraphCMS, Snipcart, & Next.js

Displaying a list of physical locations is helpful, but showing them on a map, giving your potential customers the ability to see how close each store really is to their location is even better.

GraphCMS supports adding coordinates as a field to our data models, where we can dynamically pull those coordinates in and add them to a map.

We'll walk through how we can loop through our store locations and add each one to a new React Leaflet map. We'll also learn about some pitfalls of using React Leaflet in an app framework like Next.js and how we can solve it with dynamic imports and manual image imports.

* [Dynamic Import - nextjs.org](https://nextjs.org/docs/advanced-features/dynamic-import)
* [Leaflet Map Marker Rendering - github.com](https://github.com/Leaflet/Leaflet/issues/4968)

I also have a whole course on how to [Build Maps using React Leaflet](https://egghead.io/courses/build-maps-with-react-leaflet) if you want a further dive on the topic. 

Add All Store Locations to a React Leaflet Map with Location Data From GraphCMS

If our store supports physical locations, we want to give our customers the opportunity to easily find out those locations so they can visit us in person. That means, we need to show them somewhere on our site.

We can take advantage of GraphCMS custom Schema Models to create a new document for each store.

We'll walk through setting up a new model for our stores and how we can query them in our app to list out all of our locations.

List Store Locations on a Page Using a Store GraphCMS Schema and Data

We are going to create a schema as we did in lesson 2, but this one is going to be for our Categories at the bottom of the home page. This will be slightly different because we are going to add a Reference field. This way we can create a reference between our categories and our products. 

Then over in the content tab, we will add our existing products to an Apparel category, an Accessory category, and a Featured category. 

Create a Product Category Graphcms Schema to Manage Product Groupings

When we import assets in React components outside of the `public` folder that Nitro reads for assets by default when running the development server we need to tell Nitro how to find them with the `devProxy` configuration option.

```typescript
export default defineNitroConfig({
  renderer: './renderer.ts',
  devProxy: {
    '/app/assets': 'http://localhost:5173/app/assets'
  }
})
```

This is ultimately inadequate in scenarios where you want to import assets arbitrarily and have them "just work" but works in a pinch.



Use devProxy in Nitro Config to Serve Static Imported Assets in Dev Mode via Vite

Learn how to use devProxy in Nitro Config with Vite to serve static assets in React components in dev mode.

Start with a basic Vite React TypeScript app and enhance it for production use by integrating Nitro as the server. 

This requires a custom Vite plugin for nitro as well as a custom renderer and manually creating Nitro config.

The other way to approach this would be to add Vite to a Nitro app instead. Same basic result.

The [Nitro config reference](https://nitro.unjs.io/config) is a great read of you'd like to explore more options.

Over the years, your application have grown huge. Sometimes, really HUGE.

Many developers have contributed to the codebase. One day they pushed one coding style, a different one another day. Sometimes even different patterns and solutions for similar problems.

You want to keep your codebase consistent. In the Angular ecosystem, there were well established patterns for doing things the right way ™️. But the old solutions are being challenged by signal-based approach.

Eventually, you ask yourself the key question: **Should you integrate with the NEW solutions or stick to the battle-tested ones, but already considered LEGACY**?

That's a very good question indeed. Don't rush with architectural decisions 🤓.

## 👉 First, think of what problems you want to solve by introducing the change.

Do you have 1k LoC Angular components? Maybe even 2k? Do you and your team enjoy working with these? 😏

Where does the **domain logic and state management code** belong to - do you have a clear guidance on which code should be put where? Have you spot that different devs implement similar features in totally different ways?

Do you keep on asking the same questions over and over again: **whether this certain piece of code** should be **imperative** (plain old object properties and variables) or **reactive** (streams)? It'd be nice to keep all thinga reactive, but more often than not, it introduces complexity.

## 👉 Second, think of long-term consequences.

You are going to have more than one way to **manage the state**. But is that really an issue? If your codebase is modular, separate modules should not depend on each other in any way. Inner abstractions of one should be invisible to the other, etc.

You are going to introduce a **new tool**. On one hand, you need to learn it, and so does your team. But on the other hand, it's a breathe of fresh air. And it's useful to question the way you've been doing things so far. Maybe there's a more effective way?

You are going to embrace signal-based APIs. And that means taking taking advantage of Zoneless Angular. This means using all modern Angular APIs. And you know that signals are the future. Why would you want to stick to the **less performant, less type-safe, less flexible and, objectively, less effective solutions**?

## 👉 Finally, plan your INCREMENTAL integration.

INCREMENTAL is the absolute keyword here. You don't want to tell your PM you need to stop delivering features because of a refactor.

Actually, there's no need for a "refactor". Just pick the first new feature to be implemented. Or pick the one that needs to be extended.

NGRX Signal Store allows you to create both very simple & small stores, as well as bigger ones. **Composition** is the key here.

**Start simple**.

Create a `withState` section with the signals that hold the state. That's already reactive. And relatively simple.

```ts
const initialState: CartState = {
  items: ...,
  rebate: ...,
}

export const CartStore = signalStore(
  withState(initialState)
);
```

Create a `withMethods` section to provide ways to change the state:

```ts
export const CartStore = signalStore(
  ...
  withMethods((store) => ({
    addItem(item: ShoppingItem): void {
      patchState(store, (state) => ({ items: [ ...state.items, item ] }));
    },
    ...
);
```

Create a `withComputed` section to provide all derived computations:

```ts
export const CartStore = signalStore(
  ...
  withComputed(({ items }) => ({
    totalPrice: computed(() => items().reduce(...))
    ...
);
```

**Start simple**.

Now you can (literally) **`inject` this code into your existing solution**. All you need is to inject your brand new NGRX Signal Store implementation into a component, or a service:

```ts
@Injectable()
class ExistingBigService {
  cartStore = inject(CartStore)
  //...  
}
```

and that's it! What's beatiful is that NGRX Signal Store should remain an implementation details (of a component, service, etc). It **shouldn't leak outside to the entire application unintentionally**. Small NGRX Signal Stores help us to **keep logic more modular**.

Don't hesitate - give NGRX Signal Store a try! Start with the [_**Scalable Signals Angular Architecture with NGRX Signal Store**_](https://egghead.io/courses/scalable-signals-angular-architecture-with-ngrx-signal-store-a33abd39) course now!

In React 19, managing script tags efficiently within components can lead to performance enhancements and simpler code structures.

Originally, using script tags directly in a React component involved complex setups, like using `useEffect` to dynamically add JavaScript code. For instance, a component might dynamically inject script tags to load external widgets. This approach, while functional, resulted in multiple script tags and duplicate iframe elements. This duplication not only cluttered the output but also negatively impacted performance by loading scripts multiple times.

The workaround for this would be to manually hoist any common scripts and maybe load them when they weren't needed by any components.

With React 19 we now have a more effective method. This involves directly placing the script tag within the React component's return statement. This approach ensures that React handles the script loading, avoiding the duplication of script tags.

By implementing the script tags this way, the loading initiator becomes React DOM, which efficiently manages script loading and deduplication. This setup prevents multiple requests for the same script when the component is rendered multiple times, enhancing the overall application performance.

Furthermore, directly embedding the script tag simplifies the code, making the component cleaner and more maintainable.

Efficiently Render Script Tags in React 19 Components

Learn how to efficiently render script tags in React 19 components to improve performance by avoiding duplicate script loads and simplifying your code.

Let's learn how to dynamically manage title tags in React 19 applications. Rendering `<title>` dynamically is simple enough, however, a challenge arises when multiple title tags are present in the document, which can lead to issues with screen readers and search engine optimization (SEO). The solution presented involves ensuring that only one title tag is rendered at a time by using conditional rendering.

Also we need to make sure to have a single string within the title tag using a template literal, ensuring our HTML remains valid and optimized.


Deduplicate Title tags with React 19

Learn to manage multiple title tags in React 19 dynamically. Ensure accessibility and SEO by preventing duplicate title tags with clear examples.

In React 19, we can easily add a title tag like "Starship Deets" which then appears in the head section of the HTML even when we render it inside our components. This method also applies to meta tags such as character set and viewport settings, which are also lifted to the head section automatically.

This is an awesome feature because it maintains the same composition style we are familiar with in React components. It simplifies the handling of HTML head elements without needing extra setups like `useEffect` for accessing the head section. Even in situations where our components are rendering within a body element, like within a div, we can manage our head content directly within our components. React takes care of hoisting these elements where they need to go.


Hoist Title and Meta tags in React 19

Hoisting title and meta tags directly in React 19 components allows for simpler composition, similar to other React elements. Manage meta and title tags.

Dax Raad, known for his strong opinions on Twitter, sat down for a chat about web dev, career moves, and building cool stuff. He's not afraid to throw some heat at popular tools like [Next.js](https://nextjs.org/), though he still helps people use it. Dax is particularly excited about local-first development, which he thinks isn't getting enough attention. He argues that sometimes the best web dev move is to step away from web dev entirely and explore other areas of programming.

When it comes to career growth, Dax encourages developers to think beyond the "web dev" label and see themselves as programmers capable of tackling any challenge. He advocates for trying out weird stuff and learning unusual languages, as these experiences can lead to unexpected opportunities. Taking smart risks in your career can open doors to awesome possibilities.

In the business world, Dax is a fan of making "asymmetric bets" - moves with low downside but huge potential upside. He applies this philosophy to his work on [SST](https://sst.dev/), reasoning that even if it fails, he'll walk away with valuable experience. He also emphasizes the importance of resisting quick payouts in favor of potentially bigger wins down the road.

Looking to the future of tech, Dax is betting on local-first development. He sees potential in getting in early on emerging technologies like [Solid.js](https://www.solidjs.com/). Building in public and making connections in new tech communities can pay off in unexpected ways.

Dax also challenges the notion of constant hyper-productivity in tech. He suggests balancing focused work with time for exploration and learning. Sometimes, he points out, what seems like a "dumb" choice (like learning a niche language) can turn out to be a smart career move in the long run.
