I was trying to use pace.js to add a page pre-loader, and basically the way this plugin works is that you just add the pace.js file to your page and add any css theme that pace.js provides, see here.

Now I did this, but my problem is, nowhere in the plugin docs have they specified how to control the load timing for the plugin. How do I actually control the load timing for the preloader plugin?

Fiddle here

The doc says the following about this plugin:

Include pace.js and the theme css of your choice on your page (as early as is possible), and you're done!

Pace will automatically monitor your ajax requests, event loop lag, document ready state, and elements on your page to decide the progress. On ajax navigation it will begin again!

If you use AMD or Browserify, require in pace.js and call pace.start() as early in the loading process as is possible.

So far I am just adding the plugin code, I am not even writing a line of js to initialize the plugin:

How do I actually control the load timing of the plugin? The other problem is the contents of the page are visible when the preloader is loading, why? Does the plugin provide a mechanism to hide the page contents while the plugin loads or is that on me?

How do I actually control the load timing of the plugin? The other problem is the contents of the page are visible when the preloader is loading, why? Does the plugin provide a mechanism to hide the page contents while the plugin loads or is that on me?

• javascript
• jquery

• did you see this page? seems pretty thorough to me... github.hubspot./pace – swatkins Commented Jun 12, 2015 at 19:00
• @swatkins , it does seem seemingly thorough ! , but i bet you would't find an example of how to add a pre-loader using this plugin , which ironically what this plugin is supposed to do ! anyways , i am probably going to move on to nprogress , which is a precedessor to this plugin , except it does't seem to have the options this plugin has ! – Alexander Solonik Commented Jun 12, 2015 at 19:04
• I'll move this to an answer. Maybe that will help – swatkins Commented Jun 12, 2015 at 19:06
• @swatkins , would be really kind of you to do so , BTW , this plugin is really weird , in the sense , it runs even without any kind of initilization(either through data-attibutes or JS) , see the fiddle jsfiddle/qw6rL75z . never seen a plugin that runs without initilization ! – Alexander Solonik Commented Jun 12, 2015 at 19:09
• 1 Also, if you want your content to be invisible, then show up after it has been loaded, then add display:none or visibility: hidden to your css, then change that in the done callback for pace: Pace.on("done", myHandler); – swatkins Commented Jun 12, 2015 at 19:14

From the docs, it states that you can set configuration options before you load the file. So, in your html page you would do something like this:

<head>
    <title>asdfas</title>
    <script>
    paceOptions = {
        ajax: false, // disabled
        document: true, // enabled
        eventLag: false, // disabled
        elements: {
          selectors: ['.my-page']
        }
    };
    </script>
    <script src="js/pace.js"></script>

This will then use the page's readyState to create the progress bar.
