Tracks async hook events related to file system operations.
npm install ah-fs
Instantiates a FileSystemActivityCollector.
Extends ActivityCollector and thus exposes the same public API with added functionality.
Parameters
$0.start Array<number> the start time of the process, i.e. the result of process.hrtime()$0.stackCapturer StackCapturer? see ah-stack-capturer which
configures how and when stacks traces are captured and processed.By default a StackCapturer is used that captures stacks for all events for
file system related types: FSREQWRAP, FSREQUESTWRAP (optional, default StackCapturer)$0.bufferLength number? determines how many elements of Buffers are
captured. By default not Buffer data is captured. (optional, default 0)$0.stringLength number? determines how much of each string is
captured. By default no string data is captured. (optional, default 0)$0.captureArguments boolean? if true arguments of callbacks
are captured when they are processed. (optional, default false)$0.captureSource boolean? if true the source code of callbacks
is captured when they are processed. (optional, default false)Getter that returns all activities related to file system operations.
Returns Map<string, object> fileSystemActivities
Cleans up all captured resources which means that they are processed, meaningful data extracted and the reference to the actual resource removed so it can be GCed.
Resources are cleaned during after and destroy events, therefore
calling this function only affects those resources for which none of these
events have fired yet.
Returns FileSystemActivityCollector fileSystemActivityCollector
Finds all buffers that are part of the resources, including arguments passed to callbacks and stringifies their value for the supplied encodings.
Parameters
encodings Array<string>? specified for which encodings to create
strings. In order to creates strings for all encodings, pass
stringify-buffer.encodings (optional, default 'utf8','hex')Returns FileSystemActivityCollector fileSystemActivityCollector
