Builtins

Digital Alchemy Core provides several built-in services that are wired automatically before any library or application services run. They're always available on TServiceParams — no depends declaration needed.

Built-in services (on TServiceParams)

Service	Type	Description
logger	GetLogger	Context-scoped logger
lifecycle	TLifecycleBase	Lifecycle hook registration
config	TInjectedConfig	Typed configuration object
scheduler	TScheduler	Cron, interval, and timeout scheduling
event	EventEmitter	App-wide event bus
als	AlsExtension	Async Local Storage
internal	InternalDefinition	Utilities and boot metadata

These are part of the boilerplate module, which always wires first. They live at config.boilerplate.* for configuration and are wired in this order: als → configuration → logger → scheduler.

Standalone exports

These utilities are exported directly from @digital-alchemy/core and imported at the module level — they don't appear on TServiceParams.

Export	Description
is	Type guard singleton
sleep	Async sleep with cancel support
debounce	Identifier-keyed debounce
each	Parallel Promise.all over array/Set
eachSeries	Sequential iteration
eachLimit	Bounded-concurrency iteration
SECOND, MINUTE, HOUR, DAY, WEEK	Millisecond constants

import { is, sleep, each, SECOND } from "@digital-alchemy/core";

See Utilities for detailed documentation on each.
