How to Fetch All Products and Tag Them by Shopify Node API

Step 1: Set Up Your Environment

Ensure you have Node.js installed. Then, create a new Node.js project and install the required packages.

mkdir shopify-product-tagging
cd shopify-product-tagging
npm init -y
npm install shopify-api-node dotenv

Step 2: Create the .env File

Create a .env file in the root of your project to securely store your Shopify API credentials.

SHOPIFY_SHOP_NAME=your-shop-name
SHOPIFY_API_KEY=your-api-key
SHOPIFY_PASSWORD=your-password

Step 3: Create the Script

Create a file named tagProducts.js and add the following code:

require('dotenv').config();
const Shopify = require('shopify-api-node');

const shopify = new Shopify({
  shopName: process.env.SHOPIFY_SHOP_NAME,
  apiKey: process.env.SHOPIFY_API_KEY,
  password: process.env.SHOPIFY_PASSWORD
});

async function fetchAllProducts() {
  const allProducts = [];
  let params = { limit: 250 };
  let hasMoreProducts = true;

  while (hasMoreProducts) {
    const products = await shopify.product.list(params);
    allProducts.push(...products);
    if (products.length < 250) {
      hasMoreProducts = false;
    } else {
      params.page = (params.page || 1) + 1;
    }
  }

  return allProducts;
}

async function tagProducts(tag) {
  try {
    const products = await fetchAllProducts();
    console.log(`Fetched ${products.length} products.`);

    for (const product of products) {
      const updatedTags = product.tags ? `${product.tags}, ${tag}` : tag;
      await shopify.product.update(product.id, { tags: updatedTags });
      console.log(`Product ${product.id} tagged with "${tag}".`);
    }

    console.log('All products have been tagged.');
  } catch (error) {
    console.error('Error tagging products:', error.message);
  }
}

const tagToAdd = 'your-tag'; // Replace with the tag you want to add
tagProducts(tagToAdd);

Explanation

1. Environment Variables: The script uses environment variables to store sensitive information securely.
2. Fetching All Products: The fetchAllProducts function retrieves all products from Shopify, handling pagination to ensure all products are fetched.
3. Tagging Products: The tagProducts function iterates over the fetched products and updates each product with the new tag.

Step 4: Run the Script

Run your Node.js script to fetch and tag products:

node tagProducts.js

Summary

By following this guide, you will be able to fetch all products from your Shopify store and tag them using the Shopify Node API. Customize the script as needed to handle specific tagging requirements or additional product attributes. This approach allows for efficient and automated product management in your Shopify store.
