A product listing page is a fundamental aspect of any e-commerce platform. Here’s how to create one using PrimeVue Marketplace components:
<template>
<div>
<h2>Product Listing</h2>
<DataTable :value="products" paginator :rows="10" :responsiveLayout="'scroll'">
<Column field="name" header="Product Name"></Column>
<Column field="price" header="Price"></Column>
<Column field="actions" header="Actions" body="actionTemplate"></Column>
</DataTable>
<Dialog header="Product Details" v-model="displayModal">
<p>{{ selectedProduct.details }}</p>
</Dialog>
</div>
</template>
<script>
import { DataTable } from 'primevue/datatable';
import { Column } from 'primevue/column';
import { Dialog } from 'primevue/dialog';
export default {
components: {
DataTable,
Column,
Dialog,
},
data() {
return {
products: [
{ name: 'Product 1', price: 100, details: 'Details about Product 1' },
{ name: 'Product 2', price: 200, details: 'Details about Product 2' },
// More products...
],
selectedProduct: {},
displayModal: false,
};
},
methods: {
showDetails(product) {
this.selectedProduct = product;
this.displayModal = true;
},
},
};
</script>In this example, we use PrimeVue Marketplace‘s DataTable component to display a list of products. Each product has a name, price, and details. The Dialog component is used to show more information when a product is selected.
Implementing a Shopping Cart
A shopping cart is vital for any e-commerce platform. Here’s how to create a cart component to manage user-selected items:
<template>
<div>
<h3>Your Shopping Cart</h3>
<DataTable :value="cartItems" paginator :rows="5" :responsiveLayout="'scroll'">

</DataTable>
<Button label="Checkout" @click="checkout" />
</div>
</template>
<script>
import { DataTable } from 'primevue/datatable';
import { Column } from 'primevue/column';
import { Button } from 'primevue/button';
export default {
components: {
DataTable,
Column,
Button,
},
data() {
return {
cartItems: [
{ name: 'Product 1', quantity: 2, price: 100 },
{ name: 'Product 2', quantity: 1, price: 200 },
// More items...
],
};
},
methods: {
checkout() {
// Handle checkout logic here
alert('Proceeding to checkout');
},
},
};
</script>This example displays items in the shopping cart using the DataTable component from PrimeVue Marketplace. Users can see their selected items, quantities, and prices, and they can initiate the checkout process.
Step 4: Integrating Blockchain for Transactions
Utilizing blockchain for transactions can significantly enhance the security and trustworthiness of your PrimeVue Marketplace. Here’s how to integrate blockchain effectively:
Set Up a Smart Contract
To use blockchain for your marketplace, you need to create a smart contract. Smart contracts are deployed on the blockchain and facilitate transactions automatically based on predefined conditions. Here’s a simplified example of a smart contract written in Solidity:
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
contract Marketplace {
struct Product {
uint id;
string name;
uint price;
address owner;
bool sold;
}
mapping(uint => Product) public products;
function listProduct(uint id, string memory name, uint price) public {
products[id] = Product(id, name, price, msg.sender, false);
}
function buyProduct(uint id) public payable {
Product storage product = products[id];
require(msg.value >= product.price, "Not enough Ether sent.");
require(!product.sold, "Product already sold.");
product.owner = msg.sender;
product.sold = true;
}
}This smart contract allows users to list products and purchase them securely. The buyProduct function ensures that only users who send the appropriate amount of Ether can purchase the product.
Connecting the Smart Contract to Your Vue Application
To connect your smart contract to your PrimeVue Marketplace, you can use the Web3.js library. First, install Web3.js in your project:
npm install web3Then, use Web3.js to interact with your smart contract:
import Web3 from 'web3';
export default {
data() {
return {
web3: null,
contract: null,
account: null,
};
},
created() {
this.initWeb3();
},
methods: {
async initWeb3() {
if (window.ethereum) {
this.web3 = new Web3(window.ethereum);
await window.ethereum.enable();
this.account = await this.web3.eth.getAccounts()[0];
this.contract = new this.web3.eth.Contract(ABI, contractAddress);
}
},
async buyProduct(productId, price) {
await this.contract.methods.buyProduct(productId).send({
from: this.account,
value: this.web3.utils.toWei(price.toString(), 'ether'),
});
},
},
};In this example, the initWeb3 method initializes the Web3 instance, allowing your application to interact with the Ethereum blockchain. The buyProduct method facilitates the purchase of a product using the smart contract.
