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 🙏

Usage

####Single micro tasks

  // creates a MicroTaskQueue, then passes in some optional data
  var data = 0;
    queue = new MicroTaskQueue(data);

  // the following functions are added in no specific order

  // adds a single micro task
  queue.addTask(function(data) {
    console.log("task " + data);
    return data + 1;
  })
  // optional done handler called when all tasks are complete
  .done(function(result) {
    if (result instanceof Error)
      console.error(result)
    else
      console.log("complete " + result);
  });

  queue.run(data);

####Multiple micro tasks

  // creates a MicroTaskQueue, then passes in some optional data
  var data = 1,
    queue = new MicroTaskQueue();

  // adds a batch of micro tasks
  queue.addTasks([
    function(data) {
      console.log("task " + data);
      return data + 1;
    },
    function(data) {
      console.log("task " + data);
      return data + 1;
    },
    function(data) {
      console.log("task " + data);
      return data + 1;
    }
  ])
  // optional done handler called when all tasks are complete
  .done(function(result) {
    if (result instanceof Error)
      console.error(result)
    else
      console.log("complete " + result);
  });

  queue.run(data);

####Monitoring single tasks

// create a MonitoredTaskQueue, this example passes in some optional data
var data = 0;
var queue = new MonitoredTaskQueue();

// the following functions are added in no specific order

// optional beforeEach task handler
queue.beforeEach(function (data) {
  return data + 1;
})
// optional afterEach task handler
.afterEach(function (data) {
  return data + 1;
})
// adds a task with a taskDone callback handler
.addTask(function (data) {
  return data + 1;
}, function taskDone(data) {
  return data + 1;
})
// optional done handler called when all tasks are complete
.done(function (result) {
  if (result instanceof Error)
    console.error(result)
  else
    console.log("complete " + result);
});

queue.run(data);

####Monitoring task batches

  var data = 0;
  // create a MonitoredTaskQueue, this example passes in some optional data
  var queue = new MonitoredTaskQueue();

  // the following functions are added in no specific order

  // optional beforeEach task handler
  queue.beforeEach(function (data) {
    return data + 1;
  })
  // optional afterEach task handler
  .afterEach(function (data) {
    return data + 1;
  })
  // adds a batch of tasks with a taskBatchDone callback handler
  // which is called once the batch of tasks are complete
  .addTasks([
    function (data) {
      return data + 1;
    },
    function (data) {
      return data + 1;
    },
    function (data) {
      return data + 1;
    }
  ], function taskBatchDone(data) {
    return data + 1;
  })
  // optional done handler called when all tasks are complete
  .done(function (result) {
    if (result instanceof Error)
      console.error(result)
    else
      console.log("complete " + result);
  });

  queue.run(data);
