- Open the locally hosted page in a browser.
- Open DevTools to investigate the layout and functionality problems.
- Copy those changes back into the editor and return to step #1.
While tools such as live reloading have made this process easier, many developers continue to tweak code in both DevTools and their editor.
However, it’s possible to open and edit source files directly in Chrome. Any changes you make are saved to the file system and updated within the editor (presuming it refreshes when file changes occur).
Step 1: Launch Developer Tools
Open Chrome, load a page from your local file system/server and open Developer Tools from the More tools menu or press F12 or Ctrl/Cmd + Shift + I depending on your system. Navigate to the Sources tab to examine the file explorer:
Step 2: Associate a Folder with the Workspace
Click the Filesystem tab, then click + Add folder to workspace. You’ll be prompted to locate your work folder and Chrome will ask you to confirm that you Allow access. The explorer shows files on your system which can be opened with a single click:
Step 3: Edit and Save Your Code
You can now jump in and edit your code. Unsaved edits are marked with an asterisk on the file tab.
Note that you can also right-click the file tab and select Save as… to save a copy of the file elsewhere.
Step 4: Review and Undo Changes
To review changes, right-click a file tab and choose Local modifications… from the context menu:
A diff-like view is shown. The arrow icon at the bottom-left of the pane will undo all changes and revert the file to its original state.
Chrome’s Developer Tools will never be a full replacement for your favorite editor, but it can be useful when you’re making quick changes or working from another PC where your editor may not be installed.
