Build An Ecommerce Store from Scratch using Medusa and Nuxt: Part 02

#webdev #ecommerce #medusa #nuxt

Introduction

Nuxt is a meta-framework built on top of Vue.js, a JavaScript library. It features SSR, SSG, SEO, File-System routing, Caching etc. It can be used to build ecommerce storefronts.

Medusa is a toolkit for developers to create digital commerce applications. It uses a Node.js backend with the core API, plugins, and modules installed through npm.

In this project, you will learn how an ecommerce store can be built using Nuxt for the frontend and Medusa for the backend. To do that, first, you will create a Nuxt project and set a few components, pages and layouts. Then, you will link the Nuxt project with a Medusa server to get the store products and display them on the home page including a product's page, and a product detail page.

This tutorial is Part 02 of the series. It focuses on the design of the Nuxt storefront.

Prerequisites

To follow along with the tutorial you need to have some knowledge of the following:

Basic understanding of HTML, CSS, and JavaScript
Basic understanding of Node.js and npm
Basic understanding of the command line
Knowledge of Vue and Nuxt is a bonus but not a requirement.
Knowledge of Medusa is a bonus but not a requirement.

In addition to knowing these tools, your computer system should have the following packages installed:

Node.js (v16 and above)
PostgreSQL. Alternatively, you can create a free PostgreSQL database with a Neon account. This tutorial will use a database created using Neon.
yarn (optional)
git (optional)

Make the storefront layout

Before connecting the Medusa server with the storefront, you need to add some components and pages to the storefront. Open the storefront’s project my-nuxt-storefront in your preferred code editor.

You should see the following directories:

my-nuxt-storefront
├── components
├── .editorconfig
├── .eslintrc.js
├── .git
├── .gitignore
├── node_modules
├── .nuxt
├── nuxt.config.js
├── package.json
├── pages
├── README.md
├── static
├── store
├── windi.config.ts
└── yarn.lock

You will be focusing mainly on the components and pages directories to design the layout for the storefront.

Components

Components are what make up the different parts of your page. They can be reused and imported into your pages, layouts, and even other components.

The storefront you are creating will have the following components:

Logo
Navbar
Footer
Product card

Go to the components directory and delete the default components that come with the Nuxt.js installation. Then add the following files.

Logo

Add components/App/Logo.vue.

<template>
  <div class="h-16 flex items-center">
    <div class="ml-4 flex lg:ml-0 lg:mr-8">
      <nuxt-link to="/">
        <img class="h-8 w-auto" src="https://i.imgur.com/y3yU55v.png" alt=""/>
      </nuxt-link>
    </div>
  </div>
</template>

<script>
export default {
  name: 'AppLogo'
}
</script>

Navbar

Add components/App/Navbar.vue.

<template>
  <div class="sticky top-0 z-20">
    <header class="relative bg-white">
      <nav class="px-4 sm:px-6 lg:px-8 border-b border-ui-medium flex items-center justify-between">

          <div class="hidden lg:flex lg:items-center">
            <div class="hidden flex-grow items-center justify-center lg:flex text-sm font-medium">

              <nuxt-link

                class="block mt-4 mr-4 lg:inline-block lg:mt-0 text-gray-700 hover:text-gray-600 last:mr-0"
              >
                Products

      const lowestPrice = this.item.variants.reduce((acc, curr) => {
        return curr.prices.reduce((lowest, current) => {
          if (lowest.amount > current.amount) {
            return current
          }
          return lowest
        })
      }, { amount: 0 })

      return lowestPrice || { amount: 10, currency_code: 'usd' }
    }
  }
}
</script>

Pages

The pages directory contains your storefront views and routes. For this tutorial you will need only 3 pages:

Home page
Products page
Product detail page

In the pages directory, open the index.vue file and replace the code as follows:

<template>
      <div>
        <div class="bg-ui-light pb-12 lg:pb-0 w-full px-4 sm:px-6 lg:px-12">
          <div class="flex flex-col lg:flex-row items-center max-w-screen-2xl mx-auto">
            <div class="w-auto h-full object-center object-cover p-12">
              <img
                width="600"
                alt=""
                src="https://start.medusajs.com/static/9803c162c71fd1960d9d11253859c701/246b5/hero-merch.webp"
              >
            </div>
            <div>
              <h1 class="text-4xl">

              <p class="mt-2 text-lg font-normal">
                Contribute to Medusa and receive free merch<br>as a token of our appreciation
              </p>
              <button class="btn-ui mt-4 min-w-full lg:min-w-0">
                Learn more
              </button>

          </div>
        </div>

        <div
          v-if="products.length"
          class="container mx-auto px-8 py-16"

    <style>

    </style>

This page will be the home for your storefront. It is composed of a hero, header, and a grid configured to show only four products. The only thing to do here once you connect the storefront to the Medusa server will be to put the ProductCard component in a v-for loop to display the products.

Now, you need to create a new directory called products which will hold the products page, /pages/products/index.vue and the product detail page /pages/products/_id.vue. Add the following code to these pages.

Products page

Add /pages/products/index.vue

<template>
  <div class="container mx-auto p-8">
    <div class="w-full border-b border-ui-medium pb-6 mb-2 lg:mb-6 flex items-center justify-between">
      <h1 class="font-semibold text-3xl">
        All Products
      </h1>
    </div>

    <div
      v-if="products.length"
      class="grid grid-cols-4 gap-8 "
    >
      <ProductCard
        v-for="product in products"
        :key="product.id"
        :item="product"
      />
    </div>
  </div>
</template>

<script>
export default {
  name: 'ProductsIndex',
    data () {
    return {
      products: [{
        id: 1,
        title: 'Kitchen Table',
        thumbnail: 'https://picsum.photos/600/600',
        variants: [{ prices: [{ amount: 0, currency_code: 'usd' }] }]
      }]
    }
  },
}
</script>

This page is similar to the home page but without the hero header. Here you will show a grid with all the products sent by the Medusa server.

Product Detail page

Add /pages/products/_id.vue.

<template>
  <div class="container mx-auto p-8">
    <div class="flex flex-col lg:flex-row">
      <div class="lg:w-3/5 lg:pr-14">
        <div class="flex">
          <div class="hidden lg:flex flex-col items-center mr-4">
            <div class="w-auto h-full object-center object-cover px-4 space-y-4">
              <img
                v-for="image in product.images"
                :key="image.id"

On this page, you will display all the information related to a specific product. For example, sizes, images, price, description, variants, etc...

NOTE:

The three pages include a product object on the data function to showcase the design while there isn’t a server to send requests. Once you connect the storefront with the Medusa server, the data coming from the server will replace the data in the product object.

Layouts

Layouts are a great help when you want to have a basic structure for your Nuxt app. For example, a navbar and footer that will be shown on all the pages of the app. By default, a Nuxt project doesn't come with layouts, but it is easy to add them to your project.

To have a default layout on your storefront, create a layouts directory in the root of the project, and inside it, add a new file called default.vue with the following code:

<template>
  <div class="min-h-screen flex flex-col">
    <app-navbar />

    <main class="flex-1">
      <Nuxt />
    </main>

    <app-footer />
  </div>
</template>

<script>
export default {
  name: 'DefaultLayout'
}
</script>

Since the layout file was named default.vue, the layout will automatically be applied to all the pages on the storefront.

Styling

Replace the content of windi.config.ts in the root of your Nuxt.js project with the following:

import { defineConfig } from '@windicss/plugin-utils'

export default defineConfig({
  /**
   * Write windi classes in html attributes.
   * @see https://windicss.org/features/attributify.html
   */
  attributify: true,
  theme: {
    extend: {
      fontSize: {
        '2xs': '0.5rem'
      },
      maxWidth: {
        '1/4': '25%',
        '1/2': '50%',
        '3/4': '75%'
      },
      maxHeight: {
        review: 'calc(100vh - 10rem)'
      },
      boxShadow: {
        DEFAULT:
          '0 2px 5px 0 rgba(60, 66, 87, 0.08), 0 0 0 1px rgba(60, 66, 87, 0.16), 0 1px 1px rgba(0, 0, 0, 0.12)',
        error:
          '0 2px 5px 0 rgba(255, 155, 155, 0.08), 0 0 0 1px rgba(255, 155, 155, 0.70), 0 1px 1px rgba(0, 0, 0, 0.12)'
      },
      colors: {
        green: {
          DEFAULT: '#56FBB1'
        },
        blue: {
          DEFAULT: '#0A3149'
        },
        ui: {
          light: '#F7F7FA',
          DEFAULT: '#EEF0F5',
          medium: '#D9DFE8',
          dark: '#89959C'
        }
      }
    }
  }
})

Change the Default Port

Change the port where the storefront app runs by default from 3000 to 3333. To do that, open the nuxt.config.js file and add the following right after the ssr property.

server: {
  port: 3333
},

Test your Nuxt storefront.

yarn dev

Visit localhost:3333 in your browser.

The storefront just shows static data for now. You will link the storefront with the Medusa server in the next part of the tutorial series.

Conclusion

In this part of the tutorial, we designed the layout and components for the Nuxt storefront. We created components like the navbar, footer, product card, and pages for the home, products listing, and product details. We also configured layouts to provide a consistent structure across pages. We styled the components using the Windi CSS utility library and updated some configuration settings like changing the default port.

By the end, we had a basic storefront design in place with static product data. In the next part, we will connect this Nuxt frontend to the Medusa backend to fetch and display real product information, transforming it into a fully functional ecommerce site.
