Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Installation

API

FileSystemActivityCollector

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)

fileSystemActivityCollector.fileSystemActivities

Getter that returns all activities related to file system operations.

Returns Map<string, object> fileSystemActivities

fileSystemActivityCollector.cleanAllResources

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

fileSystemActivityCollector.stringifyBuffers

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
