Fugu API Tracker

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.

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.

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.

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.

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.

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.

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 Text Detection API is a subset of the Shape Detection API which provides the ability to detect and optionally transcribe text 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.

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.

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.

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.

Aggregates and logs media settings ranges and photo capabilities in JSON. Changing MediaSettingsRange and PhotoCapabilities interfaces to dictionaries will improve developer ergonomics by allowing web developers to easily log and aggregate exposureCompensation, exposureTime, colorTemperature, iso, brightness, contrast, saturation, sharpness, focusDistance, pan, tilt, zoom, and photo capabilities (redEyeReduction, imageHeight, imageWidth, fillLightMode).

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.

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.

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.

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 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.

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.

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

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

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.

The HIDDevice forget() method allows web developers to voluntarily revoke a permission to a HIDDevice that was granted by a user.

Previously named "Multi-Screen Window Placement". 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.

The NDEFReader makeReadOnly() method allows web developers to make NFC tags permanently read-only with Web NFC.

Make USBConfiguration, USBInterface, USBAlternateInterface, and USBEndpoint instances returned by the accessors on USBDevice === comparable.

Following the recent HIDDevice forget() addition[1] to the web platform, the USBDevice forget() method allows web developers to voluntarily revoke a permission to a USBDevice that was granted by a user. [1] https://groups.google.com/a/chromium.org/g/blink-dev/c/Fk-IJF63UWc

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.

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.

Following the recent HIDDevice[1] and USBDevice[2] forget() additions to the web platform, the SerialPort forget() method allows web developers to voluntarily revoke a permission to a SerialPort that was granted by a user. [1] https://groups.google.com/a/chromium.org/g/blink-dev/c/Fk-IJF63UWc [2] https://groups.google.com/a/chromium.org/g/blink-dev/c/pSM2W0TtKEI/

Gives web applications the ability to enumerate local fonts and some metadata about each. 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.

Web Custom formats let websites read and write arbitrary unsanitized payloads using a standardized web custom 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.

Enable the Origin Private File System (OPFS) part of File System Access API on Android. This includes all of the File System Access API surface, minus show*Picker() methods and Drag-and-Drop API integration. With FSA API on OPFS, a site can access its per-origin, private file system and are able to perform file operations via `FileSystemSyncAccessHandle` with improved performance. The original API, including both OPFS and non-OPFS, was shipped in M86 for desktop, and the extension with SyncAccessHandle was shipped in M102. https://chromestatus.com/feature/6284708426022912 https://chromestatus.com/feature/5702777582911488

AudioContext.setSinkId sets the ID of the audio device to use for output. This allows the AudioContext to route audio to a connected output device of user's choosing.

Provides illuminance data to web pages via the AmbientLightSensor object and the "reading" event.

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.

Allow web app windows to have a tab strip. This adds a new display mode "tabbed" and a new manifest field to allow customizations to the tab strip.

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

Chrome's implementation of Web Bluetooth does not have a way for websites to get a list of permitted devices. This feature adds the Bluetooth.getDevices() and BluetoothDevice.forget methods. getDevices() will return a list of BluetoothDevice objects that the current origin has been granted permission to use by the user. forget() will allow web developers to voluntarily revoke a permission to a BluetoothDevice that was granted by a user.

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

Introduce additional ways for web applications to introspect and control their windows, to enable critical window management functionality on the web platform. This enhancement allows web applications to maximize, minimize, and restore their windows and introspect that window display state. Further, it allows applications to be notified when the window is repositioned, and control whether the window can be resized. The window placement permission will be required for these capabilities. https://github.com/ivansandrk/additional-windowing-controls/blob/main/awc-explainer.md

When borderless mode 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 windowing control buttons (close, maximize/restore, minimize). The web app developer is responsible for drawing and input-handling for the entire window.

The Compute Pressure API offers high-level states that represent the pressure on the system. It allows the implementation to use the right underlying hardware metrics to ensure that users can take advantage of all the processing power available to them as long as the system is not under unmanageable stress. “Pressure” is a generic term by design – at the moment it is calculated based on CPU load, but future plans include using signals from temperature and battery status, for example.

Adds a Controlled Frame API available only to Isolated Web Apps (IWAs). This work will add a new Controlled Frame API which is only available to Isolated Web Apps (IWAs). Like similarly-named APIs on other platforms, Controlled Frame allows embedding all content, even third party content that can't be embedded in <iframe>. Controlled Frame also allows controlling embedded content with a collection of API methods and events. For more info on Isolated Web Apps, see the IWA explainer: https://github.com/WICG/isolated-web-apps/blob/main/README.md

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

FileSystemHandle.getUniqueId() generates a uniquely identifying string which can be used as a key, such as for IndexedDB or WebLocks. Currently, FileSystemHandle objects can be serialized by the browser to be stored as values in IndexedDB, but there is no way to generate a string which is guaranteed to be uniquely identifying.

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

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.

Add a "launch_handler" web app manifest member that enables web apps to customize their launch behavior across all types of app launch triggers. Example usage: { "name": "Example app", "start_url": "/index.html", "launch_handler": { "client_mode": "navigate-existing" } } 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.

Web Audio Render Capacity API is a way preemptively determine audio thread overload. Generally, the Web Audio renderer’s performance is affected by the machine speed and the computational load of an audio graph. However, Web Audio API does not expose a way to monitor the computational load, and it leaves developers no options to detect glitches that are the essential part of UX in audio applications. This API provides developers with a “glitch indicator”.

The "exclusionFilters" option in navigator.bluetooth.requestDevice() allows web developers to exclude some devices from the browser picker. It can be used to exclude devices that match a broader filter but are unsupported.

Support Bluetooth "classic" serial ports in the Web Serial API. Support Bluetooth "classic" serial ports (SPP) on all Chrome platforms, not just those that automatically create serial port nodes (COM ports, etc.). This will also simplify the process of connecting to a serial port which will be done in the browser without the need to access a separate system settings UI.

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.

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

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.

The Face Detection API is a subset of the Shape Detection API which provides the ability to detect human faces and facial landmarks 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.

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).
