@gvray/logger / batchMiddleware

Function: batchMiddleware()

batchMiddleware(options): LogMiddleware

Defined in: middleware/batch.ts:38

Middleware that collects log entries into batches and flushes them together.

Each log is still forwarded to output (via next()) as it happens; additionally, contexts are accumulated and passed to onFlush when either maxSize is reached or maxWait milliseconds elapse since the first entry of the batch. Useful for collecting entries for deferred in-process handling (e.g., a debug summary or on-screen panel).

Parameters

options

BatchOptions

Batch configuration, including the flush handler.

Returns

LogMiddleware

A LogMiddleware instance.

Example

logger.use(
  batchMiddleware({
    maxSize: 10,
    maxWait: 5000,
    onFlush: (ctxs) => sendToServer(ctxs),
  }),
);
