Important: Chrome will be removing support for Chrome Apps on Windows, Mac, and Linux. Chrome OS will continue to support Chrome Apps. Additionally, Chrome and the Web Store will continue to support extensions on all platforms. Read the announcement and learn more about migrating your app.
The Chrome Apps security model disallowsexternal content in iframes andthe use of inline scripting and
eval() .You can override these restrictions,but your external content must be isolated from the app.
Isolated content cannot directlyaccess the app's data or any of the APIs.Use cross-origin XMLHttpRequestsand post-messaging to communicate between the event page and sandboxed contentand indirectly access the APIs.
API Sample: Want to play with the code?Check out thesandbox sample.
Referencing external resources
The Content Security Policy used by apps disallowsthe use of many kinds of remote URLs, so you can't directly reference externalimages, stylesheets, or fonts from an app page. Instead, you can use usecross-origin XMLHttpRequests to fetch these resources,and then serve them via
blob: URLs.
Manifest requirement
To be able to do cross-origin XMLHttpRequests, you'll need to add a permissionfor the remote URL's host:
Cross-origin XMLHttpRequest
Fetch the remote URL into the app and serve its contents as a
blob: URL:
You may want to savethese resources locally, so that they are available offline.
Embed external web pages
API Sample: Want to play with the code? Check out thebrowsersample.
The
webview tag allows you to embed external web content in yourapp, for example, a web page. It replaces iframes that point to remote URLs,which are disabled inside Chrome Apps. Unlike iframes, thewebview tag runs in a separate process. This means that an exploitinside of it will still be isolated and won't be able to gain elevatedprivileges. Further, since its storage (cookies, etc.) is isolated from the app,there is no way for the web content to access any of the app's data.
Add webview element
Your
webview element must include the URL to the source contentand specify its dimensions.
Update properties
To dynamically change the
src , width andheight properties of a webview tag, you can eitherset those properties directly on the JavaScript object, or use thesetAttribute DOM function.
Sandbox local content
Sandboxing allows specified pagesto be served in a sandboxed, unique origin.These pages are then exempt from their Content Security Policy.Sandboxed pages can use iframes, inline scripting,and
eval() .Check out the manifest field description forsandbox.
It's a trade-off though:sandboxed pages can't use the chrome.* APIs.If you need to do things like
eval() ,go this route to be exempt from CSP,but you won't be able to use the cool new stuff.
Use inline scripts in sandbox
Here's a sample sandboxed page which uses an inline script and
eval() :
Include sandbox in manifest
You need to include the
sandbox field in the manifestand list the app pages to be served in a sandbox:
Opening a sandboxed page in a window![]()
Just like any other app pages,you can create a window that the sandboxed page opens in.Here's a sample that creates two windows,one for the main app window that isn't sandboxed,and one for the sandboxed page:
NOTE:A sandboxed window will not have access to the chrome.app APIs. If acallback is provided to app.window.create it will be run, but will not havethe sandboxed window provided to it.
Embedding a sandboxed page in an app page
Sandboxed pages can also be embedded within another app page using an
iframe :
Sending messages to sandboxed pages
There are two parts to sending a message:you need to post a message from the sender page/window,and listen for messages on the receiving page/window.
Post message
You can use
postMessage to communicatebetween your app and sandboxed content.Here's a sample background scriptthat posts a message to the sandboxed page itopens:
Generally speaking on the web,you want to specify the exact originfrom where the message is sent.Chrome Apps have no accessto the unique origin of sandboxed content,so you can only allowlist all originsas acceptable origins ('*').On the receiving end,you generally want to check the origin;but since Chrome Apps content is contained,it isn't necessary.To find out more,see window.postMessage.
Listen for message and reply
Here's a sample message receiverthat gets added to your sandboxed page:
