Artisan Dessert Brand: LINE Mini App Store & Nutrition Label Automation

The brand's website moved into a LINE Mini App where customers browse, share and order; behind it, recipes are turned into regulation-compliant nutrition labels and printed straight to a Bluetooth label printer

Background

A small food brand's customers live on LINE, but product information sat on a website and ordering meant a separate form. Every product shipped also needs a legally required nutrition label, which used to be calculated and laid out by hand. This project automates both the storefront and the fulfilment side.

Storefront: LINE Mini App

  • Products, brand story and ingredient content moved from the website into a LINE Mini App, so customers never leave LINE
  • Product cards share to chats as Flex Messages in one tap, turning word of mouth into new customers
  • Links straight to the order form, and the app can be added to the home screen
  • Deep links such as /products and /product/{slug} let campaigns land on a specific product
  • Asset migration is scripted, and the palette comes from the brand's own site for a consistent look

Back office: Nutrition Label Automation

  • Enter a recipe's ingredients and weights; nutrients are calculated from the Taiwan FDA food nutrient database
  • Output follows Taiwan's packaged-food nutrition labelling rules (version effective 2024-07-01), with eight nutrients per serving and per 100 g
  • A product label is generated alongside: name, net weight, ingredients by descending weight, allergens, storage and shelf life
  • Prints directly to a NIIMBOT B1 Pro over Web Bluetooth — no drivers or apps
  • Custom nutrient values for ingredients missing from the database; inputs are validated with zod to prevent miscalculation

Technical Highlights

  • No build step: a purely static frontend the brand can maintain later
  • LINE platform integration: LIFF sharing, add-to-home-screen and deep links, plus the real-world constraint that MINI App channels must bind LIFF in the Console
  • Regulatory accuracy: calculations follow the current labelling format, removing manual arithmetic errors

Good Fit For

  • Brands whose customers are on LINE and want to sell right there
  • Food businesses with changing product lines that must carry nutrition labels
  • Small e-commerce teams automating repetitive ordering, shipping and labelling work
