Building An E-commerce Store with Nuxt.js and Strapi

#nuxt #strap #ecommerce #jamstack

In this tutorial, we are going to build an E-commerce store with Nuxt.js frontend, Strapi backend, Nodemailer for sending emails, and also integrate Stripe for payments. The E-commerce store we’re going to build can be found here.

What you’ll need for this tutorial:

  • Basic knowledge of Vue.js
  • Knowledge of JavaScript

  • Node.js (v14 recommended for Strapi)

    Table of Contents:

  • Installing Strapi

  • Building the Backend API

  • Installing Nuxt.js

  • Building Frontend

  • Integrating Stripe Payments

  • Using Nodemailer for Sending Emails

Here’s what the completed version of your application will look like.

Let’s get started.

Installing Strapi

From the Strapi documentation, it says that Strapi is a flexible, open-source Headless CMS that gives developers the freedom to choose their favorite tools and frameworks while also allowing editors to easily manage and distribute their content. By making the admin panel and API extensible through a plugin system, Strapi enables the world's largest companies to accelerate content delivery while building beautiful digital experiences.

Basically, Strapi helps us build an API in no time, I mean no hassle of creating a server from scratch. With Strapi, we can do literally everything, and it’s easily customizable, we can add our code and edit functionalities easily. Strapi is simply amazing and I’m being modest about it. I’m still stunned by what Strapi can do.

Strapi provides an admin panel to edit and create APIs and also provides code that can be edited. It’s very easy to edit the code and it makes use of JavaScript.

Strapi admin panel

To install Strapi, head over to the Strapi docs at Strapi, we’ll be using the SQLite database for this project. To install Strapi, run the following commands:

    yarn create strapi-app my-project # using yarn
    npx create-strapi-app my-project # using npx
Enter fullscreen mode Exit fullscreen mode

Replace my-project with the name you wish to call your application directory, your package manager will create a directory with the name and will install Strapi.

If you have followed the instructions correctly, you should have Strapi installed on your machine. Run the following commands to start the Strapi development server:

    yarn develop # using yarn
    npm run develop # using npm
Enter fullscreen mode Exit fullscreen mode

The development server starts our app on http://localhost:1337/admin.

Building the Backend API

We have Strapi up and running, the next step is to create our content-types of our application.

  1. Creating the Product content-type
  2. Click on content-types in the side menu
  3. Add new content-type named product.
  4. Create the following fields under product content-type
    • Name as short text
    • Description as short text
    • Price as decimal number
    • Image as collection.

  5. Create as many products as you like.

  6. Creating the Category content-type

  7. Create a category content type

  8. Create the following fields under category content-type

    • Nam e as short text
    • Relations as category has many products.

  1. Creating the Order content-type
  2. Create an order content-type

  3. Create the following fields under order content-type

    • Item as JSON

  4. Creating the Subscriber content-type

  5. Create a subscriber content-type

  6. Create the following fields under subscriber content-type

    • Email as email.

Save the content-types and now we can view our API in JSON format by visiting http://localhost:1337/api/products.

Installing Nuxt.js

To install Nuxt.js, visit the Nuxt.js docs.

We want to use Nuxt in SSR mode, server hosting, and also Tailwind CSS as our preferred CSS framework, so go ahead and select those, then select the rest of the options according to your choice. Preferably leave out CI, commit-linting, style-linting, and the rest but do whatever you like, all we’ll be needing in this tutorial is what I’ve mentioned above.

To install Nuxt.js, run the following commands:

    yarn create nuxt-app <project-name> # using yarn
    npx create-nuxt-app <project-name> # using npx
    npm init nuxt-app <project-name> # using npm
Enter fullscreen mode Exit fullscreen mode

This will ask you some questions (name, Nuxt options, UI framework, TypeScript, linter, testing framework, etc.)

Once all questions are answered, all the dependencies will be installed. The next step is to navigate to the project folder and launch it by running the following commands:

    yarn dev # using yarn
    npm run dev # using npm
Enter fullscreen mode Exit fullscreen mode

We should have Nuxt running on http://localhost:3000.

Building The Frontend

Now, we can start building the frontend of our application. Let’s start by building our components, but first let’s edit our layouts at layouts/default.vue.

Head over to the layouts directory and open the default.vue file and fill it up with the following code:

    <template>
      <div>
        <Nuxt />
      </div>
    </template>

    <style>
    html {
      /* font-family: 'Nunito', 'Source Sans Pro', -apple-system, BlinkMacSystemFont, 'Segoe UI',
        Roboto, 'Helvetica Neue', Arial, sans-serif; */
      font-family: 'Nunito';
      font-size: 16px;
      word-spacing: 1px;
      -ms-text-size-adjust: 100%;
      -webkit-text-size-adjust: 100%;
      -moz-osx-font-smoothing: grayscale;
      -webkit-font-smoothing: antialiased;
      box-sizing: border-box;
    }
    *,
    *::before,
    *::after {
      box-sizing: border-box;
      margin: 0;
    }
    .button--hero {
      display: inline-block;
      color: #fff;
      text-decoration: none;
      padding: 10px 30px;
    }
    .button--green {
      display: inline-block;
      border: 1px solid #3b8070;
      color: #3b8070;
      text-decoration: none;
      padding: 10px 30px;
    }
    .button--green:hover {
      color: #fff;
      background-color: #3b8070;
    }
    .button--grey {
      display: inline-block;
      border: 1px solid #35495e;
      color: #35495e;
      text-decoration: none;
      padding: 10px 30px;
      margin-left: 15px;
    }
    .button--grey:hover {
      color: #fff;
      background-color: #35495e;
    }
    .button--delete {
      display: inline-block;
      border: 1px solid #35495e;
      padding: 5px;
      color: white;
      background-color: #35495e;
    }
    button:focus {
      outline: none;
    }
    .container {
      width: 80%;
    }
    </style>
Enter fullscreen mode Exit fullscreen mode

Building the Hero Section

Execute the following code to create a HeroSection.vue file.

    cd components
    touch HeroSection.vue
Enter fullscreen mode Exit fullscreen mode

Fill up the HeroSection.vue file with the code below.

    <template>
      <div
        class="hero relative max-h-screen flex flex-col justify-center items-center text-center mx-auto bg-cover"
      >
        <div class="relative m-10 md:m-20">

    /* Sample `apply` at-rules with Tailwind CSS
    .container {
    @apply min-h-screen flex justify-center items-center text-center mx-auto;
    }
    */
    .hero {
      background-color: #9c7474dc;
    }

Building the Ads Section

Still in the components folder create an Ads.vue file by running the following command:

    touch Ads.vue
Enter fullscreen mode Exit fullscreen mode

Then fill it up with the following code:

    <template>
      <div class="bg-primary ads flex justify-center items-center">
        <h3 class="text-white text-lg ml-6 sm:text-2xl font-bold">

      </div>
    </template>

    <script>
    export default {
      name: 'Ads',
    }
    </script>

    <style scpoed>
    </style>
Enter fullscreen mode Exit fullscreen mode

Here, all we’re doing is linking to an image from our static folder and displaying some promo messages.

Building the Footer Section

Execute the following code to create a Footer.vue file.

    touch Footer.vue
Enter fullscreen mode Exit fullscreen mode

Fill it up with the following code:

    <template>

Building the Vuex Store

Vuex is a state manager that is popularly used with Vue.js. We’ll be setting up a simple store with Vuex in this section.

Execute the following code to open up the index.js file in the store folder.

    cd store
    code index.js
Enter fullscreen mode Exit fullscreen mode

Then fill up index.js with the following code:

    export const state = () => ({
      allProducts: [],
      featuredProducts: [],
      menProducts: [],
      womenProducts: [],
      cartItems: [],
    })

    export const getters = {
      /* 
        return items from store
      */
      allProducts: (state) => state.allProducts,
      featuredProducts: (state) => state.featuredProducts,
      menProducts: (state) => state.menProducts,
      womenProducts: (state) => state.womenProducts,
      getCart: (state) => state.cartItems,
      getCartTotal: (state) =>
        state.cartItems.length < 1
          ? '0'
          : state.cartItems
              .map((el) => el.price * el.quantity)
              .reduce((a, b) => a + b),
    }

    export const actions = {
      async addItemToCart({ commit }, cartItem) {
        await commit('setCartItem', cartItem)
      },
      async deleteCartItem({ commit }, id) {
        await commit('removeCartItem', id)
      },
    }

    export const mutations = {
      setProducts: (state, products) => (state.allProducts = products),
      setFeaturedProducts: (state, products) => (state.featuredProducts = products),
      setMenProducts: (state, products) => (state.menProducts = products),
      setWomenProducts: (state, products) => (state.womenProducts = products),
      setCartItem: (state, item) => state.cartItems.push(item),
      removeCartItem: (state, id) =>
        state.cartItems.splice(
          state.cartItems.findIndex((el) => el.id === id),
          1
        ),
    }

Installing and Using @nuxtjs/swal

We need some kind of alert system to improve the user experience of our website, for example, to alert users when they carry out a specific task. We’ll be using @nuxtjs/swal module for that purpose.

Execute the following code to install the package.

    yarn add @nuxtjs/swal # using yarn
    npm install @nuxtjs/swal # using npm
Enter fullscreen mode Exit fullscreen mode

Then add the following code to your nuxt.config.js file.

    plugins: ['~/plugins/vue-swal'],

    build: {
        /*
         ** Run ESLint on save
         */
        extend(config, ctx) {
          if (ctx.dev && ctx.isClient) {
            config.module.rules.push({
              enforce: 'pre',
              test: /\.(js|vue)$/,
              loader: 'eslint-loader',
              exclude: /(node_modules)/,
            })
          }
        },
        /*
         ** Add vue-swal
         */
        vendor: ['vue-swal'],
      },
Enter fullscreen mode Exit fullscreen mode

Installing and Using @nuxtjs/strapi

We’ll be using @nuxtjs/strapi module for to make API calls to our Strapi back-end.

Execute the following code to install the package.

    yarn add @nuxtjs/strapi@^0.3.4 # using yarn
    npm install @nuxtjs/strapi@^0.3.4 # using npm
Enter fullscreen mode Exit fullscreen mode

Then add the following code to your nuxt.config.js file:

    modules: [
        ...
        '@nuxtjs/strapi',
      ],

    strapi: {
        url: process.env.STRAPI_URL || 'http://localhost:1337/api',
        entities: ['products', 'orders', 'subscribers'],
      },

    env: {
        STRAPI_URL: `http://localhost:1337/api`,
      },
Enter fullscreen mode Exit fullscreen mode


shell

Building the Newsletter Section

Execute the following code to create a NewsLetter.vue file.

    cd components
    touch NewsLetter.vue
Enter fullscreen mode Exit fullscreen mode

Fill it up with the code below:

    <template>
      <div
        class="sm:flex mx-auto items-center m-10 justify-center space-x-6 sm:space-x-20 m-3 sm:m-6 mx-6"
      >
        <div>
          <h1 class="text-lg m-7">Sign Up For NewsLetter</h1>
        </div>
        <div>
          <form @submit="handleSuscribe">
            <input
              id=""
              v-model="email"
              class="p-2 m-3 sm:m-0 border border-solid border-t-0 border-l-0 border-r-0 border-b-1 outline-none border-black"
              type="email"
              name=""
              placeholder="email"
            />
            <button type="submit" class="button--grey">Subscribe</button>
          </form>
        </div>
      </div>
    </template>

    <script>
    export default {
      name: 'NewsLetter',
      data() {
        return {
          email: '',
        }
      },
      methods: {
        async handleSuscribe(e) {
          e.preventDefault()
          this.$swal({
            title: 'Successful!',
            text: 'Thanks for Subscribing',
            icon: 'success',
            button: 'Ok',
          })
          await this.$strapi.$subscribers.create({ Email: this.email })      
          this.email = '' // clear email input
        },
      },
    }
    </script>
Enter fullscreen mode Exit fullscreen mode

This newsletter section gives users the privilege to sign up for our e-commerce store’s newsletter. We use the @nuxtjs/strapi module to create a new subscriber every time our handleSuscribe method is invoked.

Building the Nav Section

Execute the following code to create a Nav.vue file.

    cd components
    touch Nav.vue
Enter fullscreen mode Exit fullscreen mode

Add the following code to the file:

    <template>
      <div class="navbar flex text-white relative">
        <div class="nav-item-center flex space-x-6 sm:space-x-20 p-5 mx-auto">
          <NuxtLink to="/">Home</NuxtLink>
          <NuxtLink to="/all">All</NuxtLink>
          <NuxtLink to="/men">Men</NuxtLink>
          <NuxtLink to="/women">Women</NuxtLink>
        </div>
        <div class="cart fixed bottom-0 right-0 shadow-md m-3">
          <p class="p-1 cartCount text-xs absolute top-0 right-0">
            {{ getCart.length }}
          </p>
          <NuxtLink to="/cart">
            <p class="pt-3 px-2">Cart</p>
          </NuxtLink>
        </div>
        <!-- <div class="ham-menu shadow-md fixed bottom-0 right-0 m-3 sm:hidden">
          <p class="text-center pt-3">menu</p>
        </div> -->
      </div>
    </template>

    <script>
    import { mapGetters } from 'vuex'
    export default {
      name: 'Nav',
      computed: {
        ...mapGetters(['getCart']),
      },
    }
    </script>

    <style scoped>
    .ham-menu {
      background-color: #000;
      width: 3em;
      height: 3em;
      border-radius: 1.5em;
    }
    .cart {
      background-color: rgb(163, 87, 129);
      width: 3em;
      height: 3em;
      border-radius: 1.5em;
    }
    .navbar {
      background-color: rgb(24, 20, 22);
    }
    .cartCount {
      background: #000;
      border-radius: 30%;
    }
    </style>
Enter fullscreen mode Exit fullscreen mode

In the Nav section component, we are making use of the Vuex store, we are using the getCart getter to get the number of items added to the cart from the Vuex store.

Building the Featured section

Still in the components folder, execute the following code to create a Featured.vue file.

    touch Featured.vue
Enter fullscreen mode Exit fullscreen mode

Add the following lines of code to the Featured.vue component:

    <template>
      <div>
        <div
          class="sm:grid sm:grid-cols-3 md:grid-cols-3 gap-6 justify-center items-center"
        >
          <div
            v-for="(product, i) in data"
            :key="i"
            class="flex flex-col max-h-screen shadow-xl m-8 sm:m-2 md:m-4 justify-center items-center"
          >
            <!-- <div>{{ product }}</div> -->
            <div class="img-wrapper h-3/4 mx-auto max-h-screen">
              <img
                class="flex-shrink h-1/2"
                :src="`http://localhost:1337${product.attributes.image.data.attributes.formats.small.url}`"
                alt=""
              />
            </div>
            <div>
              <p class="text-center m-3">
                {{ product.attributes.name }}
              </p>
              <NuxtLink :to="`/products/${product.id}`">
                <button class="button--green mb-4">View Product</button>
              </NuxtLink>
            </div>
          </div>
        </div>
      </div>
    </template>

    <script>
    export default {
      name: 'Featured',
      props: ['data'],
    }
    </script>

    <style scoped>
    </style>
Enter fullscreen mode Exit fullscreen mode

What we’re doing here is displaying the data from our products API. This component is responsible for the cards that are displayed on the homepage, men and women products pages. We pass the data as props from the parent down to the featured component, then loop through it and display the data properly. If you recall correctly, our products content-type has a name and image property.

This component is responsible for displaying the details about individual product details and it also provides the option to add a product to our cart.

Execute the following code to create a Products.vue file.

    touch Products.vue
Enter fullscreen mode Exit fullscreen mode

Add the following lines of code:

    <template>
      <div>
        <div
          class="sm:grid grid-cols-2 justify-center shadow-lg items-center gap-3 m-5 md:m-5"
        >
          <div>
            <img
              class="max-h-screen"

            />
          </div>
          <div class="sm:m-3 md:m-5 p-3 sm:p-0">
            <p class="my-2">
              <span>Price: </span>{{ data.attributes.price | formatPrice }}
            </p>
            <span class="my-2">Quantity: </span
            ><input
              v-model="cartItem.quantity"
              class="p-3 border border-solid border-t-0 border-l-0 border-r-0 border-b-1"
              type="number"
            />
            <p class="my-2 text-sm">{{ data.attributes.description }}</p>

              @click="
                addItemToCart(cartItem)
                displayMessage()
              "
            >
              Add to Cart
            </button>
          </div>
        </div>
      </div>
    </template>

    <script>
    import { mapActions } from 'vuex'
    export default {
      name: 'Products',
      props: ['data'],
      data() {
        return {
          cartItem: {
            id: this.data.id,
            name: this.data.attributes.name,
            url: `http://localhost:1337${this.data.attributes.image.data.attributes.formats.small.url}`,
            price: this.data.attributes.price,
            quantity: 1,
          },
        }
      },
      methods: {
        ...mapActions(['addItemToCart']),
        displayMessage() {
          this.$swal({
            title: 'Cart Updated!',
            text: `${this.data.name} was added to your cart!`,
            icon: 'success',
            button: 'Ok',
          })
        },
      },
      filters: {
        formatPrice(price) {
          return `$${price}`
        },
      },
    }
    </script>

That’s all for our components.

We can now start building our pages with Nuxt.js. Nuxt.js provides automatic page routing when we build pages. Amazing right!!.

Building our Homepage

Execute the following code to create an index.vue file in the pages directory.

    cd pages
    touch index.vue
Enter fullscreen mode Exit fullscreen mode

Then we fill it up with the following code:

    <template>
      <div>
        <HeroSection />
        <Nav class="sticky top-0" />
        <div class="sm:w-11/12 md:w-4/5 mx-auto">
          <h1 class="m-5 font-bold text-lg">Featured Products</h1>
          <Featured class="mx-auto" :data="featuredProducts" />
        </div>
        <Ads class="mx-auto sm:m-10" />
        <NewsLetter class="mx-auto" />
        <Footer />
      </div>
    </template>

    <script>
    import { mapGetters } from 'vuex'
    export default {
      async asyncData({ $strapi, $http, store, error }) {
        try {
          const response = await this.$strapi.$products.find({
            featured: true,
            populate: '*'
          })

          store.commit('setFeaturedProducts', response.data)
        } catch (e) {
          error(e)
        }
      },
      data() {
        return {
          featuredProds: [],
        }
      },
      computed: {
        ...mapGetters(['featuredProducts']),
      },
    }
    </script>

    <style scoped>
    /* Sample `apply` at-rules with Tailwind CSS
    .container {
    @apply min-h-screen flex justify-center items-center text-center mx-auto;
    }
    */
    </style>
Enter fullscreen mode Exit fullscreen mode

What we’re doing here is basically creating our homepage using the components we created earlier on. Furthermore, we’re using @nuxtjs/strapi package to fetch data (featured products) from our Strapi backend API inside of our asyncData() lifecycle method and then we commit the data to the Vuex store. Then we get data from the store to display on our homepage through our featuredProducts getter.

Building All Products Page

Still in the pages directory, execute the following code to create an all.vue file.

    touch all.vue
Enter fullscreen mode Exit fullscreen mode

Fill the all.vue file up with the following code:

    <template>
      <div>
        <Nav class="sticky top-0" />
        <div class="sm:w-11/12 md:w-4/5 mx-auto">
          <h1 class="m-5 font-bold text-lg">Our Collection</h1>
          <div class="flex justify-center text-center mx-auto">
            <Featured :data="allProducts" />
          </div>
        </div>
        <Ads class="mx-auto sm:m-10" />
        <Footer />
      </div>
    </template>

    <script>
    import { mapGetters } from 'vuex'
    export default {
      async asyncData({ $strapi, $http, store, error }) {
        try {
          const response = await this.$strapi.$products.find({ populate: '*' })
          store.commit('setProducts', response.data)
        } catch (e) {
          error(e)
        }
      },
      data() {
        return {
          products: [],
        }
      },
      computed: {
        ...mapGetters(['allProducts']),
      },
    }
    </script>

    <style scoped></style>
Enter fullscreen mode Exit fullscreen mode

Here, we’re doing the same thing as we did in the index.vue page, the only difference is that we’re fetching all of our products from the Backend API.

Building the Men Products Page

Execute the following code to create a men.vue file.

    touch men.vue
Enter fullscreen mode Exit fullscreen mode

Then proceed to fill it up with the following code:

    <template>
      <div>
        <Nav class="sticky top-0" />
        <div class="md:w-4/5 sm:w-11/12 mx-auto">
          <h1 class="m-5 font-bold text-lg">Men's Collection</h1>
          <div class="flex justify-center text-center mx-auto">
            <Featured :data="menProducts" />

      async asyncData({ $strapi, $http, store, error }) {
        try {
          let response = await this.$strapi.$products.find({ populate: '*' })
          response = response.data.filter(
            (el) => el.attributes.category.data.attributes.name === 'men'
          )
          store.commit('setMenProducts', response)
        } catch (e) {
          error(e)
        }
      },
      data() {
        return {
          menProds: [],
        }
      },
      computed: {

We just built our cart page and if you look at the code above closely, you’ll notice some methods that we’ve not defined yet. In the next section, we’ll define them when we integrate Stripe payments.

Integrating Stripe Payments

To get started with stripe, go to Stripe, and register to obtain your API keys before proceeding with this tutorial.

Once you’ve done that, I’ll assume you’ve gotten your API keys and you’re ready to proceed.

Installing Stripe Package

Execute the following code to install Stripe.

    yarn add stripe # using yarn
    npm install stripe # using npm
Enter fullscreen mode Exit fullscreen mode

Look for the .env.example file in the root folder of your Strapi application and rename it to .env. Then add the following line of text to it:

STRIPE_KEY=<YOUR_STRIPE_KEY>
Enter fullscreen mode Exit fullscreen mode

Replace <YOUR_STRIPE_KEY> with your Stripe credentials.

Then proceed as follows to open up the order.js controller.

    cd src/api
    cd order
    cd controllers
    code order.js # open in your editor
Enter fullscreen mode Exit fullscreen mode

Edit the contents of order.js to look like:

    'use strict';

    const stripe = require('stripe')(process.env.STRIPE_KEY)

    const MY_DOMAIN = 'http://localhost:3000/cart';
    const { createCoreController } = require('@strapi/strapi').factories;
    module.exports = createCoreController('api::order.order', ({ strapi }) => ({
        async create(ctx) {
                    const { cartDetail, cartTotal } = ctx.request.body
                    // build line items array
                    const line_items = cartDetail.map((cartItem) => {
                        const item = {}
                        item.price_data = {
                            currency: 'usd',
                            product_data: {
                                name: cartItem.name,
                                images: [`${cartItem.url}`]
                            },
                            unit_amount: (cartItem.price * 100).toFixed(0),
                        },
                        item.quantity = cartItem.quantity
                        return item;
                    })
                    // create order
                  await strapi.service('api::order.order').create({ data: {
    item: line_items}});     
                    const session = await stripe.checkout.sessions.create({
                        payment_method_types: ['card'],
                        line_items,
                        mode: 'payment',
                        success_url: `${MY_DOMAIN}?success=true`,
                        cancel_url: `${MY_DOMAIN}?canceled=true`,
                    })
                    return { id: session.id}
                } 
    }));
Enter fullscreen mode Exit fullscreen mode

What we’ve done here is to redefine the create endpoint. Now when we hit the /order/create endpoint, we generate a line_items array which is stored in our database and also sent to Stripe as product details along with other essential details related to purchases. Finally, we return a JSON object containing an id with the Stripe session ID.

That’s all for Stripe on the backend. Next, open your Nuxt.js application to add Stripe support on the frontend.

Installing @stripe/stripe-js

To start using Stripe in our Nuxt.js application, we have to install a package to help us make the process easier. Execute the following code to install @stripe/stripe-js.

    yarn add @stripe/stripe-js # usnig yarn
    npm install @stripe/stripe-js # using npm
Enter fullscreen mode Exit fullscreen mode

Open up your cart.vue file, then add the following lines of code to the file:

    export default {
      data() {
        return {
          dataItems: {},
          session: {},
          stripe: {},
          stripePromise: {},
        }
      },
      computed: {
        ...mapGetters(['getCart', 'getCartTotal']),
      },
      mounted() {
        this.displayMessage()
      },
      methods: {
        async handleSubmit(e) {
          e.preventDefault()
          const response = await this.$http.$post(
            `http://localhost:1337/api/orders`,
            {
              cartDetail: this.getCart,
              cartTotal: this.getCartTotal.toFixed(2),
            }
          )
          this.$swal({
            title: 'Please wait',
            text: 'redirecting you to stripe, click ok',
            icon: 'success',
            button: 'Ok',
          })
          // stripe logic
          const stripePromise = loadStripe(process.env.STRIPE_KEY)
          const session = response
          const stripe = await stripePromise
          const result = await stripe.redirectToCheckout({
            sessionId: session.id,
          })
          console.log(response)
          if (result.error) {
            this.$nuxt.context.error(result.error.message)
          }
        },
        // using vue-swal to display messages
        displayMessage() {
          if (this.$route.query.success) {
            this.$swal({
              title: 'Order placed!',
              text: 'Thanks for placing your orders',
              icon: 'success',
              button: 'Ok',
            })
          } else if (this.$route.query.canceled) {
            this.$swal({
              title: 'Order canceled!',
              text: "continue to shop around and checkout when you're ready.",
              icon: 'warning',
              button: 'Ok',
            })
          }
        },
        formatCartTotal(num) {
          if (num > 0) {
            return num.toFixed(2)
          } else {
            return num
          }
        },
        ...mapActions(['deleteCartItem']),
      },
      filters: {
        formatPrice(price) {
          return `$${price}`
        },
        formatQuantity(num) {
          const qtyNum = num === 1 ? `${num} unit` : `${num} units`
          return qtyNum
        },
      },

Replace <YOUR_STRIPE_KEY> with your Stripe credentials*.* Now, we should have Stripe working across the whole application.

Using Nodemailer for Sending Emails

To install Nodemailer, run:

    yarn add nodemailer # using yarn
    npm install nodemailer # using npm
Enter fullscreen mode Exit fullscreen mode

Open up your Strapi application and execute the following code to access the subscriber.js controller.

    cd src/api
    cd subscriber
    cd controllers
    code subscriber.js
Enter fullscreen mode Exit fullscreen mode

Add the following lines of code to your subscriber.js file:

    'use strict';

    const nodemailer = require('nodemailer')

    module.exports = {
        async create(ctx) {
            const { Email } = ctx.request.body
            const existingSub = await strapi.services.subscriber.find({ Email })
            if (!existingSub) {
                await strapi.services.subscriber.create({ Email })
                try {
                    let transporter = nodemailer.createTransport({
                        service: "gmail",
                        auth: {
                            user: <your_email>,
                            pass: <your_password>,
                        }
                    })
                    const mailOptions = {
                        from: 'Unique essense stores',
                        to: `${Email}`,
                        subject: 'Welcome',
                        text: `Hey @${Email}, Thanks for subscribing to our NewsLetter`
                    };
                    await transporter.sendMail(mailOptions)
                } catch (error) {
                    console.log(error)
                }
            }
            return Email
        }
    };

In the code above, using Nodemailer, we’ve set up an email service that sends out notifications to subscribers.

In order for Nodemailer to work with Gmail, you need to turn on less secured app access. You can do so here.

Conclusion

Well devs, that’s all for now. I hope this tutorial has given you an insight into how to build your own E-Commerce store with Strapi. You could even add more features to your store if you like.
