Mini cart

A small cart with steppers, a badge and a subtotal, all local.

Quantity steppers, a count badge that pops and a subtotal in the visitor's currency format. The cart lives only in the component: there is no checkout, nothing is saved and nothing is sent. Products are marked as sample content until you pass your own.

Build one with your agent

Paste this into your agent. It asks you before it signs in, pays or goes further than checking and publishing.

Build me a Taggor component like "Mini cart" (mini-cart): A small cart with steppers, a badge and a subtotal, all local. Fetch https://taggor.dev/agent-setup/prompt.md and follow its instructions to set me up for Taggor. Ask me before you sign in, create an account, accept terms, pay for anything or type a secret. Check it with `taggor check` and publish it with `taggor publish`, and stop there. Do not promote it to production, attach it to a site, roll back anything or use --yes, --force or --force-drop-invalid unless I ask for exactly that in this conversation.
