View page resources

This guide teaches you how to use Chrome DevTools to view a web page's resources. Resources are the files that a page needs in order to display correctly. Examples of resources include CSS, JavaScript, and HTML files, as well as images.

This guide assumes that you're familiar with the basics of web development and Chrome DevTools.

# Open resources

When you know the name of the resource that you want to inspect, the Command Menu provides a fast way of opening the resource.

1. Press Control+P or Command+P (Mac). The Open File dialog opens.

   

   Figure 1. The Open File dialog

2. Select the file from the dropdown, or start typing the filename and press Enter once the correct file is highlighted in the autocomplete box.

The Browse resources section below shows you how to view resources from various parts of the DevTools UI. If you ever want to inspect a resource in the Network panel, right-click the resource and select Reveal in Network panel.

# Browse by directory

To view a page's resources organized by directory:

1. Click the Sources tab to open the Sources panel.

2. Click the Page tab to show the page's resources. The Page pane opens.

   

   Figure 6. The Page pane

   Here's a breakdown of the non-obvious items in Figure 6:

   • top is the main document browsing context.
   • airhorner.com represents a domain. All resources nested under it come from that domain. For example, the full URL of the comlink.global.js file is probably https://airhorner.com/scripts/comlink.global.js.
   • scripts is a directory.
   • (index) is the main HTML document.
   • iu3 is another browsing context. This context was probably created by an <iframe> element embedded in the main document HTML.
   • sw.js is a service worker execution context.

3. Click a resource to view it in the Editor.

# Browse by filename

By default the Page pane groups resources by directory. To disable this grouping and view each domain's resources as a flat list:

1. Open the Page pane. See Browse by directory.

2. Click More Options and disable Group By Folder.

   

   Figure 8. The Group By Folder option

   Resources are organized by file type. Within each file type the resources are organized alphabetically.
