@mj-biz-apps/orders-server

The bootstrap. Its job is to make sure every @RegisterClass decorator in this app has actually fired before a request is served.

Why it exists

MJ resolves entity subclasses and remotable operations through ClassFactory at runtime. A decorator only registers when its module is loaded, and a bundler will happily tree-shake a module nothing imports by name. The failure mode is quiet and expensive: Metadata.GetEntityObject returns the base entity, Save() writes the row without running a single business rule, and the order books with no journal entry.

So this package imports the Load* anchors explicitly:

LoadOrderEntityServer();
LoadRefundPaymentOperation();      // 'Orders.RefundPayment'          (D17)
LoadApplyAccountCreditOperation(); // 'Orders.ApplyAccountCredit'     (D68)
LoadPreviewPriceOperation();       // 'Orders.PreviewPrice'           (D69)
LoadDefaultPriceResolver();        // the resolver the walk falls back to
LoadPromotionEngine();             // the promotion qualifier seam    (D70)
LoadTaxResolver();                 // the address → jurisdiction seam (D73)

Each anchor is an empty exported function. Its only purpose is to be a name a bundler cannot prove is unused.

Adding a registered class? Add its anchor here. Nothing will fail loudly if you forget — the base class will be used instead, and the first symptom is a financial one.

Also here

• config.ts — server configuration
• src/generated/ — CodeGen's GraphQL resolvers. Do not edit; see the Entities package README.
• MJ_SERVER_EXTENSIONS — webhook + checkout edge declarations. MJ bootstrap collects this (or package.json memberjunction.serverExtensions) from hosts that list this package in dynamicPackages.server[]. Host mj.config.cjs serverExtensions[] overlays by DriverClass.
• GET /checkout/:slug — public HTML host for a distribution; POSTs stay on the same edge. Pre-auth. Host serverExtensions[] can set Enabled: false to suppress. Settings: TrustedProxyHops (default 0 — ignore X-Forwarded-For; set to the number of reverse proxies that append to it), RateLimitMax / RateLimitMaxGlobal.

Verifying registration

The integration suite is the real check: it resolves entities through the same ClassFactory a request does, so a missing anchor shows up as a rule not running. If a check fails in a way that looks like "the guard didn't fire", suspect a missing anchor before suspecting the guard.
