https://github.com/googlechrome/chrome-extensions-samplesOfficial samples for Chrome Extensions and the deprecated Chrome Apps platform. This collection provides implementation patterns for various Chrome APIs, including hardware access (USB, Bluetooth, HID), system integration (fileSystem, storage, identity), network communication (messaging, sockets), and UI features (framelessWindows, webview). It also includes a CSP-compliant version of the Google API javascript client (gapi) for Chrome Packaged Apps.
The mDNS browser sample demonstrates how to use UDP multicast support in Chrome Packaged Apps to browse mDNS (Multicast DNS) servers. This is useful for discovering home appliance devices and other network services that use protocols like Apple's Bonjour.
Limitations and Known Issues:
FileSystem API, which enables users to select files directly from their local disk so the application can perform read and write operations.The Google Drive Uploader is a Chrome extension sample that demonstrates how to use the chrome.identity.getAuthToken() API to perform OAuth2 authentication and subsequently access the Google Drive API.
To use the application for uploading files, you can drag and drop files directly from your desktop onto the app interface.
videoCapture permission to query user media without triggering a warning. The app showcases the ability to process images captured from a video camera using WebGL and save the resulting pictures to the syncFileSystem, allowing images to be synced across devices.identity API to authenticate with Instagram. Specifically, it uses the launchWebAuthFlow method to obtain an OAuth token, which is then used to request and display the user's logged-in view as raw JSON from an authenticated endpoint.The Telnet sample is a Chrome extension that demonstrates how to use the Sockets API to act as a TCP client. It connects to aardmud.org on port 4000 and features an ANSI color renderer to display terminal output with color support.
Key capabilities demonstrated:
The Text Replacer extension demonstrates how to replace text on a web page in response to different user triggers. Users can configure up to 5 pairs of text replacements via the extension's popup.
Replacements are triggered in three ways:
Alt Texter is a Chrome extension sample that demonstrates how to generate accessible image descriptions using on-device AI. It leverages two specific Chrome AI APIs:
When a user selects 'Generate alt text' from an image's context menu, the extension analyzes the image, generates a functional description, and provides options to translate or copy the text to the clipboard.
FileSystem API, which enables users to select files directly from their local disk for reading and writing operations. This sample is conceptually similar to the mini-code-edit sample found in the Chrome App samples repository.chrome.hid API. It specifically shows how to control a ThingM blink(1) mk2 RGB LED light using USB HID Feature Reports.The Weather sample is a basic 5-day weather forecast extension. It demonstrates how to use geolocation to automatically retrieve weather conditions for the user's current location. It also provides functionality for users to manually add cities and toggle between different temperature formats.
Key technical features demonstrated:
The Clock sample is a widget-like application designed to demonstrate Chrome extension capabilities. It provides several utility features including:
