enhanced-analytics

A couple of convenient tools for populating dataLayer ecommerce event data or even more.

You can use them either on the Frontend or the Backend sides. The Faacebook Pixel events can be configured on both sides, just to increase pixel's performance.

integrated services:
  ✅ Google Analytics & GA4 / Tag Manager (Browser Only)
  ✅ Klaviyo (Server+Browser) https://www.klaviyo.com/

• Install npm i -S klaviyo-api@2.11 when this lib is being used at NodeJs
• This will auto-install js when running it in a broswer.

  ✅ Facebook (Server+Browser)

• install npm i -S facebook-nodejs-business-sdk@13.0.0 when running in NodeJs env

  ✅ FullStory (Broswer Only) https://www.fullstory.com/

• Install npm i @fullstory/browser when this lib is being used at NodeJs

1.2 Google Analytics

... somewhere in components:

import useAnalytics from 'enhanced-analytics';

const MyComponent = () => {
  const analytics = useAnalytics();

  useEffect(() => {
    const myProductItems = [];

    //
    // Google Analytics: track basket add/remove items
    //
    analytics
      .withBasket(/* TDataBasket|Record<any>|null */) // <- this can be empty or TDataBasket AND resolver.basket is being invoked as well
      .events.ga()
      .getEECCheckoutList()
      .when(() => true /* or your condition */) // <----- or omit this call, if there is no any conditions
      .push(); // <- inject event into the dataLayer (config dataLayerName default is 'dataLayer');

    //
    // Google Analytics: track search/on-page product items
    //
    analytics
      .withCatalog(/* your array of goods; any custom data[] or T_EA_DataProduct[] */)
      // ^ the resolver.product is being invoked over the each item in the given collection
      .events.ga()
      .getEECProductsList()
      .push();

    //
    // Google Analytics: track product details
    //
    analytics
      .withCatalog(/* array with just one product data [T_EA_DataProduct] */)
      // ^ the resolver.product is being invoked over the each item in the given collection
      .events.ga()
      .getEECProductDetails()
      .when(() => /* producItem is loaded */)
      .push();

    //
    // Google Analytics: track order creation
    //
    analytics
      .withOrder(/* TDataOrder or any custom object */)
      // ^ invokes resolver.order
      .events.ga()
      .getEECPurchased()
      .when(() => !thisOrderWasSeen) // why not, implement your logic, that prevents duplicated events
      .push();
  }, []);

  return <></>;
};

1.2.Klaviyo UI / FullStory UI / Facebook Pixel

import useAnalytics from 'enhanced-analytics';

const MyComponent = () => {
  const analytics = useAnalytics();
  const order = useOrder();

  // Track PageView
  useEffect(() => {
    // page tracking
    const evtPageView = analytics.withPage().events;

    evtPageView.fullstory().trackPageView();
    evtPageView.klaviyo().trackPageView();
  }, []);

  // Track User Indetify
  useEffect(() => {
    // page tracking
    const evtPageView = analytics.withPage().events;
    evtProfile.fullstory().trackIdentify();
    evtProfile.klaviyo().trackIdentify();
    evtPageView.fb().trackPageView();
  }, []);

  // Track Order Complete + Custom event "OrderSeen"
  useEffect(() => {
    const evtOrder = analytics.withOrder(order).events;
    const evtProfile = analytics.withProfile({
      userName: order.customerFullName,
      phone: order.customerPhone,
    }).events;
    // the custom event. This is going to track 'orderSeen' event
    const evtCustom = analytics.withMisc('orderSeen', {
      orderId: order.id,
      orderDate: moment(order.dateCreated).format(),
      orderTotal: order.total,
    }).events;

    // push the 'eec.purchase' evet along with order details
    evtOrder.ga().getEECPurchased().push();

    // indetify current session (this will link anonymous events to this user by email)
    evtProfile.fullstory().trackIdentify();
    evtProfile.klaviyo().trackIdentify();
    evtPageView.fb().trackIdentify();

    // any other custom events
    evtCustom.fullstory().trackCustom();
    evtCustom.klaviyo().trackCustom();
    evtPageView.fb().trackCustom();
  }, []);
};

2 Configure (Backend Side)

Simple snippet with Express.Js as middleware:

app.use(
  analyticsMiddleware({
    absoluteURL: 'https://www.your-domain.lviv.ua/',
    serverAnalytics: {
      testing: false,
      klaviyo: {
        enabled: true,
        token: 'pk_token-goes-here',
        sdk: require('klaviyo-api'), // npm i klaviyo-api@2.1.1
      },
      userIdentification: {
        // this field is used this way: incoming request has body and we
        // check if this field contains req.body, if so we store the whole req.body
        // into app.locals.customer = req.body
        reqBodyKey: 'customerPhone',
      },
    },
    resolvers: (req) => ({
      order(evtPayload: any) {
        // in this case { order, products } (see order tracking at 2.2.KalviyoAPI below)
        const order = evtPayload.order;
        const orderProducts = evtPayload.products;
        return {
          id: order.id,
          revenue: order.total,
          tax: 0,
          quantity: order.features.length,
          coupon: order.coupon,

        };
      },
      profile() {
        return app.locals.customer.customerPhone
          ? {
              email: `john.smith@test.com`,
              firstName: app.locals.customer.customerFullName,
              phoneNumber: '5551234567',
              address: {
                country: 'United States',
                city: 'Boston',
                postcode: '02110',
                region: 'MA',
                countryCode: 'UA',
                street: app.locals.customer.customerAddress,
              },
            }
          : null;
      },
      eventUUID() {
        return app.locals.evtUuid;
      },
      product(input: TDataList<IDataProduct>) {
        const l = input.items.map((prodItem) => {
          return {
            id: prodItem.id,
            title: prodItem.title,
            description: prodItem.description,
            price: prodItem.price,
            salePrice: prodItem.price,
            isSale: false,
            brand: prodItem.seller,
            category: prodItem.categoryName,
            sku: prodItem.sku,
            list: 'main',
            url: `${req.protocol}://${req.hostname}/product/${prodItem.id}/${prodItem.sku}`,
            imageUrl: prodItem.imageUrl,
          };
        });
        return l;
      },
      page() {
        return {

        };
      },
      session() {
        return {
          // agent, fbp and ip are optional when using fb tracking
          agent: req.headers['user-agent'],

          ip: req.ip,
        };
      },
    }),
  })
);

Another configuration for NextJs:

// src/utils/ea.ts
// Server Side EA Configuration for NextJs
const getServerEA = (req: GetServerSidePropsContext['req']) => {
  const ea = useAnalytics({
    absoluteURL: "https://my-store.com/",
    affiliation: "My Store",
    currency: "USD",
    integrations: {
      testing: true,
      fb: {
        enabled: true,
        pixelId: "PIXEL-ID",
        token: "PIXEL-TOKEN",
        sdk: bizSdk,
        testCode: "TESTxxxxx",
      },
    },
    resolvers: {
      eventUUID() {
        return Date.now().toString(32);
      },
      session() {
          // agent, fbp and ip are optional when using fb tracking
        return {
          agent: req.headers["user-agent"],
          fbp: req.cookies["_fbp"],
          ip: req.socket.remoteAddress,
        };
      },
      profile() {
        const user = /* get session user info */
        return user
          ? {
              email: user.email,
              firstName: user.username,
            }
          : null;
      },
      basket() {
        return {
          total: 0,
          coupon: null,
          quantity: 0,
          lastAdded: [],
          lastRemoved: [],
          products: [],
        };
      },
    },
  });

  return ea;
}

Begin checkout:

import useAnalytics from 'enhanced-analytics';

const evtPayload = { order, products };
// you can define your own payload
// and handle it at your resolvers.order function
await useAnalytics()
  .withOrder(evtPayload)
  .s2s.klaviyo()
  .trackInitiateCheckout();

2.2.FB Pixel (Server+UI)

This examples shows how to send server-side (NextJs) fb events and then re-process them from the UI.
