# Modules (https://docs.salla.dev/twilight/react/api/modules)



Check here before writing your own request: the engine probably has a module for it. A module is a small object of plain async functions plus a `queries` object of TanStack Query options, built on the shared [client](https://docs.salla.dev/twilight/react/api/client). Import each from its own subpath, for example `@salla.sa/twilight-theme-engine/api/cart`.

Every module page follows the same order: what it is for with a minimal example, a table of methods, the query keys, and gotchas. For how to call a module in a loader or a component, see the [Overview](https://docs.salla.dev/twilight/react/api#make-a-request).
