removeProduct

Deletes a product by its _id. Only Manager and Admin. The ODM's relation guard refuses to delete a product that is still referenced — by purchase orders, inventory records, or its own child products.

note

Import alias The code below imports the framework as lesan — that's the path alias this repo's app uses (see Project Layout). In your own project, import from @hemedani/lesan (npm/Bun) or jsr:@hemedani/lesan (Deno) instead.

Registration (mod.ts)

import { grantAccess, setTokens, setUser } from "@lib";
import { coreApp } from "../../../mod.ts";
import { removeProductFn } from "./removeProduct.fn.ts";
import { removeProductValidator } from "./removeProduct.val.ts";

export const removeProductSetup = () =>
  coreApp.acts.setAct({
    schema: "product",
    actName: "removeProduct",
    preAct: [setTokens, setUser, grantAccess([{ roles: ["Manager", "Admin"] }])],
    validator: removeProductValidator(),
    fn: removeProductFn,
  });

The validator (removeProduct.val.ts)

import { object, objectIdValidation } from "lesan";
import { selectStruct } from "../../../mod.ts";
import { activeRoleMixin } from "@lib";

export const removeProductValidator = () => {
  return object({
    set: object({
      ...activeRoleMixin,
      _id: objectIdValidation,
    }),
    get: selectStruct("product", 1),
  });
};

set is activeRoleId + _id. get is depth 1.

The implementation (removeProduct.fn.ts)

import { type ActFn, ObjectId } from "lesan";
import { product } from "../../../mod.ts";
import { throwError } from "@lib";

export const removeProductFn: ActFn = async (body) => {
  const {
    set: { _id },
  } = body.details;

  const removed = await product.deleteOne({
    filter: { _id: new ObjectId(_id as string) },
  });

  !removed && throwError("product not found");
  return removed;
};

1. product.deleteOne removes the document.
2. !removed && throwError("product not found") errors on a miss.

Products have forward relations (parent, tags) and a big reverse map: they're referenced by child products (children), tags (products back-ref), purchase orders, and inventory records. The delete guard checks all of those before removing the document.

In the workflow

Cleanup for a decommissioned item. In practice, products are more often deactivated (active: false) than deleted, precisely because so many downstream documents reference them — removeProduct is for the rare case of a truly orphaned catalog entry.

Errors & fixes

Error	Meaning	Fix
product not found	No product has that _id.	Check the id.
please clear below relations status before deletion: ...	Purchase orders, inventory records, tags, or child products still reference this product.	Clear the references first (e.g. update the purchase order / inventory / child product relations), then delete again.
activeRoleId is required	No activeRoleId in set.	Add it (ghost: any string, e.g. "ghost-role").
Active role not found	activeRoleId isn't one of the user's roles.	Pass a real roleId.
You cant do this	Active role isn't Manager/Admin (or ghost).	Elevate the role or use the ghost token.
superstruct "expected ObjectId-like string"	_id isn't a valid ObjectId.	Send the 24-hex id string.
