We created a free course to create your first GraphQL server (from scratch) using Node and TypeScript. TypeScript and GraphQL are a powerful combo, but there's a lot of confusing edges if you're getting it setup the first time.

In this course we cover the basics of getting TypeScript setup with Node, how GraphQL works, and how to set up a GraphQL server using Apollo server. It's two hours long, it comes with complete code examples, and we walk through the code step-by-step.

It's taught by my friend, Shopify-engineer Hassan Djirdeh and he's integrated what he's learned using GraphQL in production as an engineer at Shopify. We've already had over 1,300 students enroll and it's been getting great reviews so far.

Complete Guide to Qwik

Now that we have our home page where we show the catalog we are very happy because we are seeing our application take shape. As we have seen, it is very simple to create our pages and the integration with Supabase is truly sensational for how simple and fast it is.
But now we want to implement a detail page for our products, this allows us to add more useful information to the user because we can, for example, show product reviews left by other buyers. Furthermore, another functionality that we can implement is to show the stock of the product itself on the page.
Let's see how we can create a dedicated route for the detail part.
First, we need to create a route to view the details of the article so let's create this structure:

qwik-e-commerce
├── src
│   ├── routes
│   │   ├── detail
│   │   │   ├── [slug]
│   │   │   │   └── index.tsx

Let's analyze the newly created structure in detail, under the 

 folder. Here we define the component that will render the detail of our product.
So with this structure, we have defined a new application route that will be

https://my-website.com/detail/<product_slug>/


Here we can see that we are referring to a field called slug which is not currently present in our application.
So as we said before we can exploit Supabase migrations to create the new field.

Let's create the file where we can write our migration:

pnpm supabase migration new add_product_slug_field

 we are going to insert our migration script.

alter table "public"."products" add column "slug" text;

---

# Product Detail

Now that we have our home page where we show the catalog we are very happy because we are seeing our application take shape. As we have seen, it is very simple to create our pages and the integration with Supabase is truly sensational for how simple and fast it is.
But now we want to implement a detail page for our products, this allows us to add more useful information to the user because we can, for example, show product reviews left by other buyers. Furthermore, another functionality that we can implement is to show the stock of the product itself on the page.
Let's see how we can create a dedicated route for the detail part.
First, we need to create a route to view the details of the article so let's create this structure:

```shell
qwik-e-commerce
├── src
│   ├── routes
│   │   ├── detail
│   │   │   ├── [slug]
│   │   │   │   └── index.tsx
```

Let's analyze the newly created structure in detail, under the `routes` folder we have the `detail` folder, and inside we have a `[slug]` folder. Here we define the component that will render the detail of our product.
So with this structure, we have defined a new application route that will be
`https://my-website.com/detail/<product_slug>/`
Here we can see that we are referring to a field called slug which is not currently present in our application.
So as we said before we can exploit Supabase migrations to create the new field.

Let's create the file where we can write our migration:

```shell
pnpm supabase migration new add_product_slug_field
```

And inside the new file `<timestamp>_add_product_slug_field.sql` we are going to insert our migration script.

```SQL
alter table "public"."products" add column "slug" text;
```

Let's update our `seed.sql` file with the new field: `slug`.

```SQL
insert into public.products
  (name, description, price, image, slug)
values
  ('Spiky Cactus', 'A spiky yet elegant house cactus - perfect for the home or office. Origin and habitat: Probably native only to the Andes of Peru', 20.95,  'spiky_cactus.webp', 'spiky-cactus'),
  ('Tulip Pot', 'Bright crimson red species tulip with black centers, the poppy-like flowers will open up in full sun. Ideal for rock gardens, pots and border edging.', 10.95, 'tulip_pot.webp', 'tulip-pot'),
  ('Aloe Vera', 'Decorative Aloe vera makes a lovely house plant. A really trendy plant, Aloe vera is just so easy to care for.', 10.45, 'aloe_vera.webp', 'aloe-vera'),
  ('Fern Blechnum Gibbum', 'Create a tropical feel in your home with this lush green tree fern, it has decorative leaves and will develop a short slender trunk in time.', 12.95, 'fern_blechnum_gibbum.webp', 'fern-blechnum-gibbum'),
  ('Assorted Indoor Succulents', 'These assorted succulents come in a variety of different shapes and colours - each with their own unique personality.', 42.35, 'assorted_indoor_succulents.webp', 'assorted-indoor-succulents'),
  ('Orchid', 'Gloriously elegant. It can go along with any interior as it is a neutral color and the most popular Phalaenopsis overall.', 30.75, 'orchid.webp', 'orchid');
```

And we launch the following command to apply the changes to our local database.

```shell
pnpm supabase db reset
```

Once the migration is complete we are ready to render the details of our articles.
So let's implement the detail page.
