Documentation / @zerotal/core / logger / LogProvider
Class: LogProvider
Defined in: provider/LogProvider.ts:52
Service provider that wires logging into the application.
Registers the log binding (a LogManager built from the logging
config, enriched with the app name and environment), installs the
LoggerMiddleware for per-request access logs (unless
logging.requests is false), and subscribes to the core lifecycle events
(AppBooted, and 4xx/5xx RequestHandled / RequestFailed) to route them
through the logger. Subscriptions are torn down on stop.
Feature packages log their own activity (slow queries, job/mail/scheduler
failures, the auth audit trail) through their own bridge, which resolves the
log binding when logging is installed — so the logger knows nothing about them.

Parameters

Properties
provides
staticprovides: readonly ["log"]
Defined in: provider/LogProvider.ts:53
Container tokens this provider registers. Required when using the array form of app.defer([Provider, ...]).
Example
static override provides = ['cache'] as const;
Overrides
environments
staticenvironments:AppEnvironment[]
Defined in: provider/LogProvider.ts:54
Environments in which this provider is active. Defaults to all of them.
Overrides
dependsOn?
staticoptionaldependsOn?: (app) =>ServiceProvider[]
Defined in: provider/ServiceProvider.ts:35
Other providers this one needs. They are pulled into the application automatically (transitively, de-duplicated) and guaranteed to boot before this provider — so you only have to register the feature you want, not its plumbing. Reference the provider classes directly:
Parameters
app
Returns
Example
static override dependsOn = [FlowProvider];

priority?
staticoptionalpriority?:number
Defined in: provider/ServiceProvider.ts:42
Boot-order tiebreak among providers with no dependsOn relationship.
Lower boots earlier; defaults to 0. Handy for framework-core providers
(e.g. static override priority = -100).
