Michalak

christophemichalak.com is the official online store of French pastry chef Christophe Michalak — cakes, pâtisserie, viennoiserie, chocolate, épicerie and masterclasses, with home delivery via Chronopost. The site runs on PrestaShop 1.6 with a custom theme (michalak-v2) and a stack of business-specific modules.

I work on Michalak as the backend developer and maintainer, building the custom PHP modules and overrides that the shop needs on top of stock PrestaShop — shipping logic by product category, accounting documents tied to specific order states, and integrations with the client’s ERP.

Tech stack

My work — custom modules & overrides

The repo only tracks the customized parts of PrestaShop; the PS core lives in a Docker volume. My contributions revolve around three business needs:

1. Shipping planning by product category

Custom modules that drive delivery scheduling rules per product category — some items (fresh pastries, cakes, viennoiserie) only ship on specific days, while épicerie / chocolate items follow the standard Chronopost flow. The carrier selection, available delivery dates and cut-off times are computed from the categories present in the cart.

• modules/lvx_categoryplandelivery/ — category → shipping plan mapping
• modules/lvx_shippingplanningdelivery/ — front-office delivery date picker driven by cart content
• modules/planningdeliverybycarrier/ — carrier-level planning rules

2. Order slip generator tied to order status

A PDF / document generation flow that produces order slips for specific PrestaShop order states, so the back-office team can issue the right accounting document automatically when an order transitions to a given status (shipped, delivered, refunded…).

• modules/lvx_orderslipgenerator/ — order slip generation hooked on order-state changes
• modules/lvx_refordergenerator/ — re-order document flow
• modules/statscompta/ — accounting / VAT stats module

3. myPOS integration

A connector module (modules/lvx_mypos_link/) that bridges PrestaShop with the client’s myPOS point-of-sale system:

• Outbound — when an order reaches a configured PrestaShop order state, the module forwards it to the configured webhook URL with a secured token, so myPOS receives the order automatically.
• Carrier mapping — a back-office configuration screen maps each PrestaShop carrier to its myPOS counterpart, so the right shipping method is sent through.
• Configurable triggers — the order state, the eligible carrier and the webhook endpoint / token are all configurable from the admin panel (no code change needed when the workflow evolves).
• Inbound — exposes a front controller so myPOS can call back into PrestaShop to update order references and statuses.

Other contributions

• Module maintenance across the custom module ecosystem (lvx_*, recrutement, coursereservation, lvx_masterclassbloc, lvx_coffretmanager…).
• PrestaShop overrides in override/ and custom front controllers under controllers/front/ for business-specific routes.
• One-shot SQL migrations in migrations/ — applied manually via the browser when a release needs schema changes outside the PrestaShop installer.
• Theme touch-ups in themes/michalak-v2/ (Smarty templates + Sass compiled with Compass).

Local environment

docker-compose up -d

DB credentials: user root, password admin.

Theme CSS workflow

The theme uses Sass / Compass. From themes/michalak-v2/:

compass watch    # dev — recompiles on save
compass compile  # one-time build

Entry point: sass/michalack_v2/style.scss → css/michalack_v2.min.css.

Deployment

GitLab CI deploys automatically via git-ftp on push to either branch.
