A South African men's apparel store on Spree 5.6 + Next.js 15. 160 products
live, three markets, live Malaysian courier rates, customer-owned carts.
What is here:
storefront/ the Next.js app
backend/ ONLY the custom Spree code. Spree itself is a prebuilt image
that mounts no app code, so every file here needs an explicit
volume entry in docker-compose.yml or it is silently ignored.
catalogue/ the scripts that loaded and maintain the products
docs/ manifest, mock registry, napkins
Real .env files are committed deliberately. This lives on the house's private
Gitea, and a clone that runs beats a clone that needs a secrets handover.
LANDMINE.md maps every key, what it opens, and what must be rotated before this
repo goes anywhere less private.
The admin API key used to be a literal in six catalogue scripts. They now read
SPREE_ADMIN_KEY from the environment and refuse to run without it.

# EasyParcel live courier rates as a real Spree shipping cost.
|
|
#
|
|
# The storefront has always shown live EasyParcel quotes — 20 couriers for a
|
|
# Melaka address, with logos and durations. What was missing is that the chosen
|
|
# one never reached Spree, so the customer picked "City-Link RM6.79" and the
|
|
# order was charged whatever the flat-rate method said. The quote screen looked
|
|
# decorative because of that last missing step, and I removed it on that reading.
|
|
# This restores it by making the selection the thing Spree actually charges.
|
|
#
|
|
# The amount is read from order.private_metadata['easyparcel_amount'], written
|
|
# ONLY by the storefront's /api/shipping/select route, which re-fetches the live
|
|
# quotes server-side and confirms the chosen service_id really costs that. The
|
|
# browser can PATCH cart metadata directly, so an unverified amount here would
|
|
# let a customer set their own shipping to one sen.
|
|
#
|
|
# No quote chosen => nil => no shipping rate => no fulfillment => checkout cannot
|
|
# complete. That is deliberate: a Malaysian order must carry a real courier.
|
|
#
|
|
# The class is defined INSIDE to_prepare: at initializer load time Spree is not
|
|
# autoloaded yet, and `require 'spree/shipping_calculator'` raises LoadError
|
|
# under Zeitwerk — that took the container down once.
|
|
#
|
|
# Bind-mounted — the prebuilt image mounts no app code. See docker-compose.yml.
