libdashstore

MSSQL schema + domain API for Dash. One class, methods mirror the file path under src/store/.

import sql from 'mssql';
import LibDashStore from 'libdashstore';

const pool = await sql.connect({ /* … */ });
const client = await new LibDashStore(pool); // runs initialize() (ensure schema, no purge)

SQL lives in src/sql/<table>.js. Schema DDL: src/schema.js / import 'libdashstore/schema'.

ID fields in the JS API use camelCase …Id (DB columns stay snake_case). googleAuthId is always google_auth.id (the logged-in user), not companyuser.id.


Schema

Kein Migrations-Code: Wir gehen von einer frischen DB aus (npm run reset-db). Schema nur in src/schema.js; Anpassungen an einer laufenden DB manuell per sqlcmd, nicht im Repo.

Method Description
initialize() Runs all SCHEMA_SCRIPTS (IF NOT EXISTS). Does not purge.
purge() Drops all known tables + number procedure.

company

Method Signature Returns
create ({ iso639, name, taxrate, reducedtaxrate, googleAuthId }) { id, rootCategoryId, languageId, taxrateId, reducedtaxrateId, taxfreerateId }
update (id, { iso639, name, taxrate, reducedtaxrate }) { id, rootCategoryId, languageId, taxrateId, reducedtaxrateId, taxfreerateId }
delete (companyId) void
list (googleAuthId) { id, name, rootCategoryId, languageId, taxrate, reducedtaxrate, taxfreerate }[]

create (transaction)

For POST /api/company:

  1. Fails if name is taken (Company name not available)
  2. Ensures language by iso639 (get or create)
  3. Ensures tax rows for taxrate, reducedtaxrate, and 0 → taxfreerateId
  4. Creates root category (parentId = null)
  5. Inserts company with all FKs set
  6. Links creator as companyuser (googleAuthId → company_id)

company.poscustomergroup_id (optional) points at the customergroup used for POS pricing in getTreeForCompany articles.

list

Returns only companies where googleAuthId has a companyuser row.

update (transaction)

For PATCH /api/company/:id:

  1. Fails if company missing / name taken by another company
  2. Ensures lang + tax rates
  3. Updates name, default_language_id, taxrate, reducedtaxrate
    (taxfreerateId / root category unchanged)

google_auth

Method Signature Returns
add (email) id
getByEmail (email) { id, email, createdAt, selectedCompanyId } | undefined
listAllowedEmails () { id, email, createdAt, selectedCompanyId }[]
removeAllowedEmail (email) void
setSelectedCompany (googleAuthId, companyId) void

Backend mapping:

  • Login: getByEmail(email)
  • CLI user manager: listAllowedEmails() / removeAllowedEmail(email) / add(email)
  • PUT /api/auth/selected-company: setSelectedCompany(googleAuthId, companyId)

companyuser

Method Signature Returns
add (companyId, googleAuthId) id
getByEmail (email) id[]
delete (id) void

lang

Method Signature Returns
create (iso639) id
getByIso639 (iso639) { id, iso639 } | undefined
ensure (iso639, tx?) id
list () { id, iso639 }[]
delete (id) void

tax

Method Signature Returns
create (rate) id
getByRate (rate) { id, rate } | undefined
ensure (rate, tx?) id
list () { id, rate }[]

category

Method Signature Returns
createUnderParent ({ googleAuthId, parentId, name }) { id, parentId, sort, name }
delete ({ googleAuthId, id }) void — blocked by FK if categoryarticle or child categories remain
getTreeForCompany (googleAuthId, companyId) { languageId, tree, articles }

createUnderParent (transaction)

  1. parentId exists, else Parent not found
  2. Walk ancestors to root; find company with root_category_id = root
  3. companyuser for (googleAuthId, companyId), else Not authorized
  4. Insert category (next sibling sort) + categorytext (name, slugified slug, company default language)

All category mutations use resolveCategoryAccess(googleAuthId, categoryId) internally. Root category cannot be deleted.

getTreeForCompany throws Not authorized if googleAuthId is not a companyuser of companyId, and Company not found if the company is missing, has no root_category_id, or no default_language_id.
