{{alias}}( [options,] [clbk] )
|
|
Returns a transform stream for debugging stream pipelines.
|
|
|
|
If the `DEBUG` environment variable is not set, no data is logged.
|
|
|
|
Providing a `name` option is *strongly* encouraged, as the `DEBUG`
|
|
environment variable can be used to filter debuggers.
|
|
|
|
Parameters
|
|
----------
|
|
options: Object (optional)
|
|
Options.
|
|
|
|
options.name: string (optional)
|
|
Debug namespace.
|
|
|
|
options.objectMode: boolean (optional)
|
|
Specifies whether a stream should operate in "objectMode". Default:
|
|
false.
|
|
|
|
options.highWaterMark: integer (optional)
|
|
Specifies the maximum number of bytes to store in an internal buffer
|
|
before ceasing to push downstream.
|
|
|
|
options.allowHalfOpen: boolean (optional)
|
|
Specifies whether a stream should remain open even if one side ends.
|
|
Default: false.
|
|
|
|
options.readableObjectMode: boolean (optional)
|
|
Specifies whether the readable side should be in "objectMode". Default:
|
|
false.
|
|
|
|

|
Callback to invoke upon receiving data.
|
