When creating an online store using Bubble, a visual programming tool, users can build a Shopify clone without writing any code. To start, register for a free Bubble account and complete introductory lessons to get familiar with the basics of Bubble. Then, choose to begin by wireframing product design or building necessary fields within the database. The initial steps include creating store, product, store page, product page, checkout, dashboard, order page, and configuring the database with data types such as user, items in cart, purchased products, owned stores, and orders. Next, create workflows to stitch everything together and make the app functional. This involves adding input elements on the create store page, creating a new store, creating a product, displaying dynamic content on the store page, adding an item to a users cart, processing payments, and creating a dashboard to track orders. With Bubble, it's possible to build a Shopify clone without any additional costs, and users can also purchase templates made by community members if they prefer not to build from scratch.
