Product Listing Page - using Graph

Optimizely Graph makes it possible to query your data in an advanced way, by using GraphQL. Querying data, using facets and search phrases, is very valuable when building "Product Listing Pages" for Commerce sites. I will describe how you can create your product listing page for Customizable Commerce, using NextJs.

We are going to use the Foundation example site in this tutorial. For more information how to setup Foundation, see https://github.com/episerver/Foundation

We will create a NextJs app where you can filter products by brand, size, color, and price. We will also be able to search using "semantic search" and normal relevance search.

Note: The templating and styling of the "product listing page" in this example has been made by a person (me) that has very poor knowledge of styling. Its just an example of how you can create a template.

Setup and start the Foundation site

Start with setting up the Foundation site, and make sure the site is running as it should. Also make sure you can login to edit/admin mode. For more information about the Foundation site, see https://github.com/episerver/Foundation

Enable Graph for the Foundation site

You need to have a Graph account to be able to send content from the Foundation site to Graph. But don't worry if you don't have any Graph account. We have prepared a Graph account with Foundation content, so you can test to create an application using our account.

Note: You can skip this part ("Enable Graph for the Foundation Site") if you don't have a Graph account. You can instead jump to the next section "Create GraphQL queries" and use the following singleKey: 5m4F2pBpXPWehc3QGqFfvohgNtgYxHQOxfmKsnqhRYDpZTBU

Install package to push content to Graph

Install the following nuget package: Optimizely.ContentGraph.Cms

Optimizely.ContentGraph.Cms

Configure your Graph account

Add the following section to appSettings.json:

  "Optimizely": {
    "ContentGraph": {
      "GatewayAddress": "https://cg.optimizely.com",
      "AppKey": "{your-app-key}",
      "Secret": "{your-secret}",
      "SingleKey": "{your-single-key}",
      "AllowSendingLog": "true"
    }
  }

And add the following to the "ConfigureServices" method in Startup.cs:

            services.AddContentGraph(x =>
            {
                x.IncludeInheritanceInContentType = true;
                x.PreventFieldCollision = true;
            });

Add a reference to "GraphCommerceIntegration" project

1. Clone the repository GraphCommerceIntegration

https://github.com/jonasbergqvist/GraphCommerceIntegration.git

2. Add the project "GraphCommerceIntegration.csproj", which you find under the "GraphCommerceIntegration" folder, to your Foundation solution.

3. Add Project reference in the Foundation site to "GraphCommerceIntegration"

4. Compile and start the Foundation site

Note: The repository contains

A class that makes scheduled job include catalog content (event synchronisation of catalog content works without referencing the project)
A class that includes all languages that has been configured on catalog content.
A class that triggers event synchronisation when prices have been changed.
Price Base class, which makes it easy to include price information on products and variations when they are pushed to Graph
Asset Base class, which makes it easy to add assets information on products and variations when they are pushed to Graph
Aggregation Base class, which makes it easy to aggregate data from variations to its related products.

Note: For more information, see the README at https://github.com/jonasbergqvist/GraphCommerceIntegration/tree/main

Add default price to Products and Variations

Add the following class to your Foundation site, to include default price on default market for products and variations:

    [ServiceConfiguration(typeof(IContentApiModelProperty), Lifecycle = ServiceInstanceScope.Singleton)]
    public class DefaultPriceContentApiModel : ContentApiModelPriceBase
    {
        private readonly ICurrentMarket _currentMarketService;

        public DefaultPriceContentApiModel(
            ContentTypeModelRepository contentTypeModelRepository,
            IContentLoader contentLoader,
            IPriceService priceService,
            ICurrentMarket currentMarketService)
            : base(contentTypeModelRepository, contentLoader, priceService)
        {
            _currentMarketService = currentMarketService;
        }

        public override string Name => "DefaultMarketPrice";

        protected override IMarket GetMarket()
        {
            return _currentMarketService.GetCurrentMarket();
        }
    }

Note: Products will get the lowest price from its related variations.

Aggregate data from Variation content to Product content

Add the following two classes, to include colors and sizes, when content is getting pushed to Graph:

Colors

    [ServiceConfiguration(typeof(IContentApiModelProperty), Lifecycle = ServiceInstanceScope.Singleton)]
    public class ColorContentApiModel : ProductAggregationContentApiModelBase<string, GenericProduct, GenericVariant>
    {
        public ColorContentApiModel(ContentTypeModelRepository contentTypeModelRepository, IContentLoader contentLoader)
            : base(contentTypeModelRepository, contentLoader)
        {
        }

        public override string Name => "Colors";

        protected override Expression<Func<GenericVariant, string>> VariationProperty => (x) => x.Color;
    }

Sizes

    [ServiceConfiguration(typeof(IContentApiModelProperty), Lifecycle = ServiceInstanceScope.Singleton)]
    public class ColorContentApiModel : ProductAggregationContentApiModelBase<string, GenericProduct, GenericVariant>
    {
        public ColorContentApiModel(ContentTypeModelRepository contentTypeModelRepository, IContentLoader contentLoader)
            : base(contentTypeModelRepository, contentLoader)
        {
        }

        public override string Name => "Colors";

        protected override Expression<Func<GenericVariant, string>> VariationProperty => (x) => x.Color;
    }

Push default product asset to Graph

Add the following class, to include the url of default product asset to products, when they are pushed to Graph

    [ServiceConfiguration(typeof(IContentApiModelProperty), Lifecycle = ServiceInstanceScope.Singleton)]
    public class DefaultImageUrlContentApiModel : CommerceAssetApiModelBase<string>
    {
        public DefaultImageUrlContentApiModel(ContentTypeModelRepository contentTypeModelRepository, IContentLoader contentLoader, IUrlResolver urlResolver)
            : base(contentTypeModelRepository, contentLoader, urlResolver)
        {
        }

        public override string Name => "DefaultImageUrl";

        public override string NoValue => string.Empty;

        protected override string GetAssets(IEnumerable<CommerceMedia> commerceMediaItems)
        {
            foreach(CommerceMedia media in commerceMediaItems.OrderBy(x => x.SortOrder))
            {
                if (ContentLoader.TryGet<IContentImage>(media.AssetLink, out var contentMedia))
                {
                    return GetUrl(media);
                }
            }

            return NoValue;
        }
    }

Create GraphQL queries

We will create a couple of GraphQL queries using the data from the Foundation site. We can use our online IDE using url https://cg.optimizely.com/app/graphiql?auth={your-single-key}. You can use our example account if you don't have any Graph account of your own: https://cg.optimizely.com/app/graphiql?auth=5m4F2pBpXPWehc3QGqFfvohgNtgYxHQOxfmKsnqhRYDpZTBU

Create ProductListing page

Create the following query (including a fragment) to handle the product listing page:

fragment GenericProductTeaser on GenericProduct {
  Name
  Code
  DefaultMarketPrice
  Brand
  DefaultImageUrl
}

query ProductListing(
  $languages: [Locales] = en
  $searchText: String,
  $brands: [String!],
  $sizes: [String!],
  $colors: [String!],
  $minPrice: Float,
  $maxPrice: Float,
  $skip: Int = 0,
  $limit: Int = 10,
  $order: GenericProductOrderByInput = { 
    _ranking: SEMANTIC,
  }) {
    GenericProduct(
      locale: $languages
      where:{
        _or:[
        {
          _fulltext: {
              match: $searchText
          }
        },
        {
          Name: {
            match: $searchText
            boost: 5
          }
        }
        ]
        DefaultMarketPrice: {
            gte: $minPrice
            lte: $maxPrice
        }
      }
      skip: $skip,
      limit: $limit
      orderBy: $order
  	) {
      total
      items {
          ...GenericProductTeaser
      }
      facets {
          Brand(filters: $brands) {
              name
              count
          }
          Sizes(filters:$sizes) {
              name
              count
          }
          Colors(filters:$colors) {
              name
              count
          }
          DefaultMarketPrice(
            ranges: [
              { to: 50 },
              { from: 51, to: 100 },
              { from: 101, to: 150 },
              { from: 151, to: 200 },
              { from: 201, to: 250 },
              { from: 251, to: 300 },
              { from: 301, to: 350 },
              { from: 351, to: 400 },
              { from: 401, to: 450 },
              { from: 451, to: 500 },
              { from: 501 },
            ]) {
              name
              count
           }
      	}
    }
}

Lets go through the query peice by peice

GenericProductTeaser

A fragment is a reusable partual query. You can think about them as blocks. We are creating a fragment that we call "GenericProductTeaser" (it can be called what ever we like) that is handling the "GenericProduct" type. "GenericProduct" is a content-type in the Foundation site, which has been pushed to Graph. We can now choose which fields (properties) to return from "GenericProduct" type. You will get intellisese by holding ctrl and clicking space (ctrl + space).

fragment GenericProductTeaser on GenericProduct {
  Name
  Code
  DefaultMarketPrice
  Brand
  DefaultImageUrl
}

Query name and Variables

We have named the query "ProductListing", but it could have been named anything. We have also added several variables to the query, which makes it possible to execute the query with many different options. You can think about a GraphQL query as a method in your favorite programming language. You name a query and add the variables to it that you like. You can then use the variables inside the query.

$languages: The languages that you want to get content for. This can be multiple languages. The values in "Locales" is the languages that you have configured in your commerce site.
$searchText: A search phrase to perform normal or semantic search
$brands: Selected brands
$sizes: Selected sizes
$minPrice: Lowest default price to get products for
$hightPrice: Highest default price to get products for
$skip: How many items from the top of the result to skip
$limit: The number of result items to get
$order: Which order to receive content.

query ProductListing(
  $languages: [Locales] = en
  $searchText: String,
  $brands: [String!],
  $sizes: [String!],
  $colors: [String!],
  $minPrice: Float,
  $maxPrice: Float,
  $skip: Int = 0,
  $limit: Int = 10,
  $order: GenericProductOrderByInput = { 
    _ranking: SEMANTIC,
  })

GenericProduct

We will query for all "GenericProduct" items using the content-type "GenericProduct". This will query all content that is of type "GenericProduct" or inherits from "GenericProduct".

GenericProduct(

Locale

The languages to query, were we use the variable $languages. Default value for $languages has been set to "en" in the query.

locale: $languages

Where

Filtering of content. Filtering will only happen for variables that has a value.

We are using an "_or" statement to match the variable "$searchText" against all searchable properties (_fullText) and "Name". We will boost result that matches "Name" by 5.

We will also filter the "default market price", based on the $minPrice and $maxPrice variables.

      where:{
        _or:[
        {
          _fulltext: {
              match: $searchText
          }
        },
        {
          Name: {
            match: $searchText
            boost: 5
          }
        }
        ]
        DefaultMarketPrice: {
            gte: $minPrice
            lte: $maxPrice
        }
      }

Skip & Limit

Skip $skip items from the top and include $limit number of items in the result

      skip: $skip,
      limit: $limit

OrderBy

Order the result based on the incoming $order variable. It will by default order the result based on "semantic search" ranking (default variable value in the query)

orderBy: $order

Total

The total number of result for the query

total

Items

Items are being used to get selected fields (properties). We are referencing the fragment "GenericProductTeaser" to get the fields (properties) specified in the fragment

items {
          ...GenericProductTeaser
      }

Facets

Facets are aggregating data for a specific field (property) and gives you the unique values together with "count" for the unique value.

We are creating facets for "Brand", "Sizes", "Colors", and "DefaultMarketPrice". The first three facets are simple facets, where we use "filters" parameter for each facet to specify which values the user has selected. The last facet is a range facet, to give the the count for different price intervals.

      facets {
          Brand(filters: $brands) {
              name
              count
          }
          Sizes(filters:$sizes) {
              name
              count
          }
          Colors(filters:$colors) {
              name
              count
          }
          DefaultMarketPrice(
            ranges: [
              { to: 50 },
              { from: 51, to: 100 },
              { from: 101, to: 150 },
              { from: 151, to: 200 },
              { from: 201, to: 250 },
              { from: 251, to: 300 },
              { from: 301, to: 350 },
              { from: 351, to: 400 },
              { from: 401, to: 450 },
              { from: 451, to: 500 },
              { from: 501 },
            ]) {
              name
              count
          	}
      	}

Create Product Details page

We will also create a product detail page, which will get a product using "code"

query ProductDetail(
  $locale: Locales = en
  $code: String!
) {
  GenericProduct(
    locale: [$locale]
    where:{
      Code: { eq: $code }
    }
    limit:1
  ) {
    items {
      Name
      Code
      DefaultImageUrl
      DefaultMarketPrice
      Brand
      LongDescription
    }
  }
}

Create NextJs application with Foundation data

We will create a NextJs app from scratch. If you want to see how the final result can be, than check out the site here: https://github.com/jonasbergqvist/GraphCommerceIntegration/tree/main/graph-commerce-example-app

Create new NextJs app

npx create-next-app@latest

TypeSript: Yes
ESLint: Yes
Tailwind CSS: Yes
src/ directory: Yes
App Router: No
Customize the defaultimport alias: No

Add dependencies

Open package.json and add the following

In devDependencies

    "@graphql-codegen/cli": "^5.0.2",
    "@graphql-codegen/client-preset": "^4.2.6",
    "@parcel/watcher": "^2.4.1",

In dependencies

    "@apollo/client": "^3.10.4",
    "graphql": "^16.8.1",
    "html-react-parser": "^5.1.10",
    "next-range-slider": "^1.0.5",

In scripts

"codegen": "graphql-codegen --watch",

Install all dependencies

Run the following command to install all the dependencies

npm install

Configure GraphQL Codegen

GraphQL codegen is a greate tool to give strongly typed queries and query result. We need to configure Codegen to use our account in Graph for the application

Create codegen.ts

Create a new file under the root folder of the application with name "codegen.ts" and add the following

import { CodegenConfig  } from '@graphql-codegen/cli'

const config : CodegenConfig = {
    schema: "https://cg.optimizely.com/content/v2?auth={your-single-key}",
    documents: ["src/**/*.{ts,tsx}"],
    ignoreNoDocuments: true,
    generates: {
        './src/graphql/': {
            preset: 'client',
            plugins: [],
        }
    }
}

export default config

Change {your-single-key} to your single-key. If you don't have any Graph account, then use

5m4F2pBpXPWehc3QGqFfvohgNtgYxHQOxfmKsnqhRYDpZTBU

Start codegen watcher

Run the following command to let GraphQL codegen continuesly check your project for GraphQL queries

yarn codegen

Use Apollo Client with one-page edit support

Apollo Client is one of many clients that has build-in GraphQL support. We will use Apollo Client in this example, but you can use any client of choose in your own projects.

Add apolloClient.tsx

Add a new file with name "apolloClient.tsx" under "src" folder

import { ApolloClient, createHttpLink, InMemoryCache } from '@apollo/client';
import { setContext } from '@apollo/client/link/context';

let client: ApolloClient<any> | undefined = undefined;

if (typeof window !== "undefined" && window.location !== undefined) {
    const queryString = window?.location?.search;
    const urlParams = new URLSearchParams(queryString);
    const preview_token = urlParams.get('preview_token') ?? undefined;

    if (preview_token) {
        const httpLink = createHttpLink({
            uri: 'https://cg.optimizely.com/content/v2',
        });

        const authLink = setContext((_, { headers }) => {
            return {
                headers: {
                    ...headers,
                    authorization: `Bearer ${preview_token}`
                }
            };
        });

        client = new ApolloClient({
            link: authLink.concat(httpLink),
            cache: new InMemoryCache()
        });

        const communicationScript = document.createElement('script');
        communicationScript.src = `{url-to-your-foundation-site}/Util/javascript/communicationinjector.js`;
        communicationScript.setAttribute('data-nscript', 'afterInteractive')
        document.body.appendChild(communicationScript);
    }
}

if (client === undefined) {
    const httpLink = createHttpLink({
        uri: 'https://cg.optimizely.com/content/v2?auth={your-single-key}',
    });

    const authLink = setContext((_, { headers }) => {
        return {
            headers: {
                ...headers
            }
        };
    });

    client = new ApolloClient({
        link: authLink.concat(httpLink),
        cache: new InMemoryCache()
    });
}

export default client;

Your need to change two things in this file:

Change {url-to-your-foundation-site} to the url where you run your Foundation site, for example https://localhost:44397
{your-single-key} to your single-key of your Graph account. Use 5m4F2pBpXPWehc3QGqFfvohgNtgYxHQOxfmKsnqhRYDpZTBU if you don't have any Graph account

Update _app.tsx to use your apollo cloent

Update_app.tsx under src/pages to be the following

import "@/styles/globals.css";
import { ApolloProvider } from "@apollo/client";
import type { AppProps } from "next/app";
import client from '../apolloClient';

export default function App({ Component, pageProps }: AppProps) {
  return (
    <ApolloProvider client={client!}>
      <Component {...pageProps} />
    </ApolloProvider>
  );
}

Create GenericProductTeaserComponent.tsx

Add a folder with name "components" under "src" and add a file with name "GenericProductTeaserComponent.tsx" in the "components" folder.

import { FragmentType, graphql, useFragment } from "@/graphql"
import { Dispatch, FC, SetStateAction, useState } from "react"; 

export const GenericProductTeaserFragment = graphql(/* GraphQL */ `
    fragment GenericProductTeaser on GenericProduct {
        Name
        Code
        DefaultMarketPrice
        Brand
        DefaultImageUrl
    }
`)

interface GenericProductTeaserProps {
    GenericProductTeaser: FragmentType<typeof GenericProductTeaserFragment>
    setSelectedCode: Dispatch<SetStateAction<string>>;
    setShowModal: Dispatch<SetStateAction<boolean>>;
}
 
const GenericProductTeaserComponent: FC<GenericProductTeaserProps> = ({ GenericProductTeaser, setSelectedCode, setShowModal}) => {
    const setSelected = (event: any) => {
        if(event?.target?.id) {
            setSelectedCode(event?.target?.id)
            setShowModal(true)
        }
      }

    const item = useFragment(GenericProductTeaserFragment, GenericProductTeaser)
    const imageUrl = 'https://localhost:44397' + item.DefaultImageUrl
        return (
            <div className="group relative">
                <div className="aspect-h-1 aspect-w-1 w-full overflow-hidden rounded-md bg-gray-200 lg:aspect-none group-hover:opacity-75 lg:h-80">
                    <img src={imageUrl} alt={item.Name ?? ''} id={item.Code ?? ''} onClick={setSelected} className="h-full w-full object-cover object-center lg:h-full lg:w-full"/>
                </div>
                <div className="mt-4 flex justify-between">
                <div>
                    <h3 className="text-sm text-gray-700">
                        <button data-modal-target="defaultModal" data-modal-toggle="defaultModal" id={item.Code ?? ''} onClick={setSelected} className="inline-flex items-center text-blue-400">
                            {item.Name}
                        </button>
                    </h3>
                    <p className="mt-1 text-sm text-gray-500">{item.Brand}</p>
                </div>
                <p className="text-sm font-medium text-gray-900">${item.DefaultMarketPrice}</p>
                </div>
            </div>
        )
}
 
export default GenericProductTeaserComponent

The GraphQL fragment GenericProductTeaser is added in the beginning of the file. This query is then used in the "GenericProductTeaserComponent". You can try to add fields (properties) that exist in GenericProduct in the fragment. You will have the fields/properties available in the GenericProductTeaserComponent a couple of seconds after you have added them and saved the file.

Test to add _score and save the file

    fragment GenericProductTeaser on GenericProduct {
        Name
        Code
        DefaultMarketPrice
        Brand
        DefaultImageUrl
        _score
    }

_score will be available in "item" inside GenericProductTeaserComponent a couple of seconds after you have saved the file.

Try to build the site

Check that everything is working by running the following command

npm run build

export default ProductListingComponent

Update index.tsx

Update index.tsx in src/pages folder to the following

import ProductListingComponent from "@/components/ProductListingComponent";

export default function Home() {
  return (
      <ProductListingComponent />
  );
}

Start the Foundation website to make images work

Start the Foundation website if its not running already. It needs to run to make images in the NextJs app work. The reason for this is that Graph only stores the link to the actual images, which lives inside the Commerce system. Everything except the images (you will get broken images) will work in case you don't start the Foundation site.

Start the NextJs app

npm run dev

You should now see some products when browsing to

http://localhost:3000/

Update ProductListingComponent to add price facet

Add RangeFacetComponent and two "useStates". The variables send in the GraphQL query will also have to pass the minPrice and maxPrice

<RangeFacetComponent
                                headingText='Price range'
                                currentHighValue={highPrice}
                                setHighValue={setHighPrice}
                                setLowValue={setLowPrice}
                                currentLowValue={lowPrice}
                                minValue={0}
                                maxValue={600}
                                facet={data?.GenericProduct?.facets?.DefaultMarketPrice as NumberFacet[]}
                            />

    const [lowPrice, setLowPrice] = useState(() => 0);
    const [highPrice, setHighPrice] = useState(() => 600)

    const { data } = useQuery(ProductListing, { 
        variables: { 
            brands, 
            colors, 
            sizes,
            minPrice: lowPrice,
            maxPrice: highPrice,
        } 
    })

Great post! The product listing parts and especially facets is exactly the thing I have been digging into myself to see if we can replace Search & Navigation with Content Graph on our sites and your example is exactly what I was looking for.

The commerce integration is so simple that I cannot understand why there is no official Commerce nuget package yet, the package has been in beta forever and it doesn't seem like there is new development aka news versions even if official roadmaps that there will be a package for this.
