propeller.json schema

The scaffolded shop's identity card. Lives at frontend/propeller.json. Owned by the shop. Edited rarely. Read by:

• propeller doctor — verify pinned versions + config drift.
• The shop's own runtime — data/config.ts (Next) or src/lib/config.ts (Vue) reads shop.mode etc. at boot to populate the <PropellerProvider>.
• propeller upgrade (Phase B, deferred) — reads template.version and customisations.ejected to decide what to apply.

Shape

{
  $schema?: string,
  template: {
    name: string,            // e.g. "propeller-shop-template-next"
    version: string,         // semver at scaffold time
    stack: 'next' | 'vue',
  },
  shop: {
    name: string,
    mode: 'b2b' | 'b2c' | 'hybrid',
    locales: string[],        // BCP-47, non-empty
    defaultLocale: string,
    currency: string,         // display symbol "€"
    currencyCode: string,     // ISO 4217 "EUR" (length 3)
    portalMode: 'open' | 'semi-closed' | 'closed',
    siteUrl: string,          // valid URL, no trailing slash
  },
  features: {
    quotes: boolean,
    authorization: boolean,
    favorites: boolean,
    clusters: boolean,
    search: boolean,
    contacts: boolean,
  },
  cms: {
    adapter: 'strapi' | 'cms' | null,
    endpoint: string,         // typically "${CMS_URL}"
    preview: boolean,
  },
  customisations: {
    ejected: string[],         // paths relative to frontend/
  },
}

Feature flags

Each flag says "this whole route tree is in use". The future propeller upgrade reads them to decide which sub-trees to diff against. At runtime they're advisory — they don't (yet) tree-shake unused routes.

For mode === 'b2c', the B2B-flavoured flags (quotes/authorization/contacts) default to false. For mode === 'hybrid', they default to true and are gated at runtime by userMode.

customisations.ejected

Phase B (propeller upgrade) will skip diffs for any file path listed here. v0.1 reserves the field; nothing reads it yet. Adding paths now is fine — the upgrade tool will pick them up when it ships.

Substitution variables

The CLI builds a substitution context from the prompt answers and runs Handlebars over every *.template.* file in the template tree. The variables available inside templates:

Variable	Type	Source
shopName	string	--name
shopDescription	string	derived from name
siteUrl	URL	--site-url
siteHostname	string	parsed from siteUrl
apiHostname	string	parsed from NEXT_PUBLIC_PROPELLER_API_URL placeholder
stack	'next' | 'vue'	--stack
shopMode	'b2b' | 'b2c' | 'hybrid'	--mode
isB2B / isB2C / isHybrid	boolean	derived from shopMode
defaultLocale	string	--default-locale
defaultLocaleLower	string	lowercased
locales / localesArray / localesJsonArray	various	--locales
currency / currencyCode	string	--currency-code
portalMode	'open' | 'semi-closed' | 'closed'	--portal-mode
portalModeConstant	OPEN | SEMI_CLOSED | CLOSED	uppercase enum form
channelId, anonymousId, taxZone	string	defaults from data/defaults.ts
cmsAdapter	'strapi' | 'cms' | null	--cms
cmsAdapterTsValue	string	'null' or "'<adapter>'"
cmsAdapterJsonValue	string	null or "<adapter>"
cmsAdapterPackage	string	propeller-v2-cms-adapter-<adapter>
cmsAdapterDisplay	string	UI-friendly label
showUserType	'Contact' | 'Customer' | null	derived from mode
featureQuotes / featureAuthorization / featureContacts	boolean	derived from mode
templateVersion	string	CLI version at scaffold time

Handlebars is run only on *.template.* files (suffix stripped on write) — everything else is verbatim. This avoids the Vue {{ }} / Handlebars {{ }} collision in regular .vue files.
