Allows web sites to communicate over GATT with nearby user-selected Bluetooth devices in a secure and privacy-preserving way. Status in Chrome is more complicated than can be captured by this form. In Chrome 56, this shipped on Android, ChromeOS, and macOS. In Chrome 70 it is shipping on Windows 10. For earlier versions of Windows and Linux, it is still behind a flag (chrome://flags/#enable-experimental-web-platform-features).

The web platform API to support programming USB devices.

Web Share Target allows websites to receive shared data (text, URLs, images) and register to be choosable by the user as targets from sharing contexts, including (but not limited to) Web Share.

Web Share API Level 2 allows sharing of files from the web to an app of the user's choosing. The API enables web developers to build share buttons that display the same system share dialog boxes used by native applications. Level 1 enabled system share dialogs; however only text and urls could previously be shared.

Installed web applications can now receive file shares, e.g. images. Using the manifest, the web application can declare which MIME types and/or file extensions it accepts. Previously, mobile platforms allowed files to be shared to native applications, but not web applications.

Implements programmatic copying and pasting of images for the Async Clipboard API. This change also updates navigator.clipboard.read() and navigator.clipboard.write() to comply with the specification. Programmatic copying and pasting of images is Chromium's top starred bug.

The enterkeyhint content attribute is an enumerated attribute that specifies what action label (or icon) to present for the enter key on virtual keyboards. This allows authors to customize the presentation of the enter key in order to make it more helpful for users.

Provides a way for websites to request information about the user’s contact(s) and provides a UI for the user to share those details in a way that makes it clear what is being shared with the website. This could be used for bootstrapping a friends list on a social network or (in an email/messaging application) to select message recipients.

The Get Installed Related Apps API (navigator.getInstalledRelatedApps) provides sites access to if their corresponding related applications are installed. Sites are only allowed to use this API if the native application has an established association with the web origin. The API was launched in Chrome 80. You can find details here: https://web.dev/get-installed-related-apps/

Periodic Background Sync is an extension of Background Sync that allows websites to register tasks to be run in a service worker at periodic intervals with network connectivity.

Allows web apps (as defined by the Web App Manifest standard) to set an app-wide badge in operating-system-specific places such as the shelf or home screen. Additionally, it gives the app a small, visible place to notify the user of new activity that might require attention, without showing a full notification. It can show additional information, such as an unread count or event type. It allows the app to convey this information when its windows are closed.

The Barcode Detection API is a subset of the Shape Detection API which provides the ability to detect and decode barcodes in an image provided by script. The image may come from any type of image buffer source such as an <image>, <video> or <canvas> tag. Some native platforms include built-in libraries for performing text detection and optical character recognition (OCR) in images. The availability of these libraries means that developers do not need to include a large third party library.

An API that allows web applications to request a screen wake lock. Under the right conditions, and if allowed, the screen wake lock prevents the system from turning off a device's screen.

Allows websites to register offline enabled content in the browser. This allows the browser to improve the offline experience and allow content browsing when the user is offline. This data could also be used to improve on-device search and to augment browsing history.

The WebOTP API (formerly called the SMS Receiver API) notifies an application when a specially-crafted SMS message is delivered to the user’s phone. The message must be addressed to the application's origin. The application only receives an OTP code in the message.

The streams APIs provide ubiquitous, interoperable primitives for creating, composing, and consuming streams of data. A natural thing to do with a stream is to pass it to a web worker. This provides a fluent primitive for offloading work to another thread. Transferable streams add this capability by allowing ReadableStream, WritableStream, and TransformStream objects to be passed as arguments to postMessage().

Lets a web application register shortcuts for common tasks. These would typically be added to the app launcher icon (for a progressive web app) enabling the user to quickly run key tasks.

This API enables developers to build powerful apps that interact with other (non-Web) apps on the user’s device via the device’s file system. After a user grants a web app access, this API allows the app to read or save changes directly to files and folders selected by the user. Beyond reading and writing files, this API provides the ability to open a directory and enumerate its contents, as well as store file and directory handles in IndexedDB to later regain access to the same content.

The async clipboard api currently does not support the text/html format. This feature adds support for copying and pasting html from the clipboard. The HTML is sanitized when it is read and written to the clipboard.

This feature allows developers to pan and tilt the camera using media constraints in getUserMedia(). https://w3c.github.io/mediacapture-image/#dom-mediatracksupportedconstraints-pan https://w3c.github.io/mediacapture-image/#dom-mediatrackcapabilities-tilt

Adds the ability to request unadjusted/unaccelerated mouse movement data when in PointerLock. If this unadjustedMovement is set to true, then the pointer movements will not be affected by the underlying platform modifications such as mouse acceleration.

Enables web applications to interact with human interface devices (HIDs) other than the standard supported devices (mice, keyboards, touchscreens, and gamepads). However, there are many other HID devices that are currently inaccessible to the web. This API allows web applications to request access to these devices, send and receive HID reports, and retrieve information about the report descriptor.

The Serial API provides an interface for connecting to serial devices, either through a serial port on the user’s system or removable USB and Bluetooth devices that emulate a serial port. This API has been requested by the hardware developer community, especially developers building educational tools, as a companion to the WebUSB API because operating systems require applications to communicate with USB-based serial ports using their higher-level serial API rather than the low-level USB API.

Web NFC aims to provide sites the ability to read and write to NFC tags when they are brought in close proximity to the user’s device (usually 5-10 cm, 2-4 inches). The current scope is limited to NDEF, a lightweight binary message format. Low-level I/O operations (e.g. ISO-DEP, NFC-A/B, NFC-F) and Host-based Card Emulation (HCE) are not supported within the current scope.

Provides a mechanism to allow users to configure a Progressive Web Application (PWA) to be launched automatically when a user logs in to the operating system.

This new API will help clients who are still using Chrome Apps to migrate to the Web, by using a simliar API to chrome.storage.managed Extensions API.

Provides efficient, low-level access to built-in (software and hardware) media encoders and decoders.

The Idle Detection API notifies developers when a user is idle, indicating such things as lack of interaction with the keyboard, mouse, screen, activation of a screensaver, locking of the screen, or moving to a different screen. A developer-defined threshold triggers the notification.

An API for querying and managing digital products to facilitate in-app purchases from web applications, in conjunction with the Payment Request API (which is used to make the actual purchases). The API would be linked to a digital distribution service connected to via the user agent. In Chromium, this is specifically a web API wrapper around the Android Play Billing API.

An API for web applications to make use of advanced handwriting recognition services (e.g. those on operating systems) to recognize text from handwriting drawings (inks) in real time. In this context, handwriting drawing means the temporal and positional information used to describe a human handwriting process.

Gives the ability for web applications to anticipate and react to computational load changes on a device. Today, no API exists to provide signals about system computation usage. This API also gives a signal about processor state with respect to speed throttling.

Enable web applications to register themselves as handlers of custom URL protocols/schemes using their installation manifest.

File Handling provides a way for web applications to declare the ability to handle files with given MIME types and extensions. The web application will receive an event when the user intends to open a file with that web application.

When the window controls overlay is enabled for installed desktop web apps, the app's client area is extended to cover the entire window--including the title bar area--and the window control buttons (close, maximize/restore, minimize) are overlaid on top of the client area. The web app developer is responsible for drawing and input-handling for the entire window except for the window controls overlay.

Enables web applications to register as https URL handlers using their web app manifest.

Adds new screen information APIs and makes incremental improvements to existing window placement APIs, allowing web applications to offer compelling multi-screen experiences. The existing singular window.screen offers a limited view of available screen space, and window placement functions generally clamp bounds to the current screen. This feature unlocks modern multi-screen workspaces for web applications.

This API is a handy way to make a web page or web app aware of any change in light intensity. See also https://w3c.github.io/sensors/

Adds the showTrigger property to the Notification interface to enable showing a notification at a specific time in the future, even if the device is offline. Websites can use this to schedule notifications without using push messages.

Gives web applications the ability to enumerate local fonts and some metadata about each. Today, no API exists to provide a list of local fonts to web applications. Also gives web applications access to table data stored within local fonts, allowing those fonts to be rendered within their applications using custom text stacks.

The BluetoothDevice.watchAdvertisements() method will enable web apps to receive events when the system receives an advertisement packet from a watched device.

Storage Foundation API is a storage API that resembles a very basic filesystem, with direct access to stored data through buffers and offsets. Our goal is to give developers flexibility by providing generic, simple, and performant primitives upon which they can build higher-level components. It's particularly well suited for Wasm-based libraries and applications that want to use custom storage algorithms to fine-tune execution speed and memory usage.

Adds image/svg+xml support to the Async Clipboard API. The current implementation of the Async Clipboard API only supports text/plain, image/png, and text/html. SVG images are popular due to their ability to encode images in a space efficiently and their ability to maintain image quality even when zooming in.

This proposal adds input events for gamepad button and axis inputs.

Pickle Clipboard API lets websites read and write arbitrary unsanitized payloads using a standardized pickling format, as well as read and write a limited subset of OS-specific formats (for supporting legacy apps). The name of the clipboard format is mangled by the browser in a standardized way to indicate that the content is from the web, which allows native applications to opt-in to accepting the unsanitized content.

Allows web apps to establish direct transmission control protocol (TCP) and user datagram protocol (UDP) communications with network devices and systems.

Device Attributes Web API is a subset of Managed Device Web API, that provides web applications the capability to query device information (device ID, serial number, location, etc).

Adds a "launch_handler" app manifest member that enables web apps to customise their launch behaviour across all types of app launch triggers. Example usage: { "name": "Example app", "start_url": "/index.html", "launch_handler": { "route_to": "existing", "navigate_existing_client": "always" } } This will cause all launches of the Example app to focus an existing app window and navigate it (if it exists) instead of always launching a new app window.

The WebSocket API provides a JavaScript interface to the RFC6455 WebSocket protocol. While it has served well, it is awkward from an ergonomics perspective and is missing the important feature of backpressure. The intent of the WebSocketStream API is to resolve these deficiencies by integrating streams with the WebSocket API.

WebTransport is a protocol framework that enables clients constrained by the Web security model to communicate with a remote server using a secure multiplexed transport.

API that describes the logical segments of a window’s viewport.

The EyeDropper API enables developers to use a browser-supplied eyedropper in the construction of custom color pickers.

An API for enabling web applications on the lock screen of a device. The API would provide a way for web applications to indicate they can be run on the lock screen, pass data from the lock screen instance of the app to the unlocked instance (and vice versa), and be notified when there is data available.

Enables Bluetooth Low Energy Scanning
