Function: executeMiddlewarePipeline()

function executeMiddlewarePipeline(
   registrations, 
   context, 
finalHandler): Promise<void | MiddlewareResult>;

Defined in: packages/core/src/middleware/pipeline.ts:64

Runs the registered middleware chain for a single JSON-RPC message, then calls finalHandler if no middleware short-circuits.

Parameters

Parameter	Type	Description
registrations	MiddlewareRegistration[] | undefined	The list of middleware or scoped-middleware to run.
context	MiddlewareContext	The shared context for the current message.
finalHandler	() => Promise<void | MiddlewareResult>	The handler to call after all middleware have run.

Returns

Promise<void | MiddlewareResult>

The result of the first short-circuiting middleware, or the result of finalHandler.

Remarks

This is the core dispatch loop used by LSPClient and LSPServer. Each middleware receives context and a next callback; calling next() hands control to the following middleware. If a middleware returns a result with shortCircuit: true the remaining middleware and finalHandler are skipped.

Scoped middleware (created with createScopedMiddleware) is automatically filtered: it only executes when matchesFilter returns true for the current message.
