PipelineBootstrap
Defined in: packages/nestjs/src/pipeline/pipeline.bootstrap.ts:74
Wraps every @nestjs/cqrs handler that runs behaviors with its pipeline, at
application bootstrap: execute of command and query handlers, handle of
event handlers. The buses read the method at call time, so they dispatch
through the pipeline unchanged.
A handler’s pipeline comes from its @UsePipeline/@SkipPipeline and the
global behaviors, compiled once. Each behavior instance is the one provider a
module registers under the behavior class; this provider never builds one.
Startup fails when a behavior has no provider or several, when a handler that
runs behaviors is request-scoped (Nest builds such a handler per request, so a
wrapped instance would never run), and, in 'strict' mode, when a behavior’s
contract is broken. Only this application’s own handler instances are wrapped,
never their class, and they are restored when the application closes.
