Example
Options pages are used to give the user the possibility to maintain settings for your extension.
Version 2
Since Chrome 40 there is the possibility to have the option page as a predefined dialogue at chrome://extensions.
The way to define an option page in the manifest.json is like the following:
"options_ui": {
"page": "options.html",
"chrome_style": true
}
This option page will behave as a dialogue, it will open as a popup, where the options.html will be displayed. chrome_style will apply a Chrome stylesheet for style consistency reasons to your options page.
The options will be automatically exposed via the context menu of the extension button or the chrome://extensions page.
You can also open the options page programmatically, for example from a popup UI:
chrome.runtime.openOptionsPage();
Version 1 (deprecated)
Example definition in manifest.json:
"options_page": "options.html"
It is recommended to use Version 2 since the options_ui behavior will be soon applied to Version 1 options pages.
Storage
Normally the settings need to persist, so using chrome.storage API is recommended. The permissions can be declared like this in the manifest.json:
"permissions": [
"storage"
]
