Microsoft Edge Developer

Hi, are you a web developer or designer?

“No, I just want to share feedback on Microsoft Edge.”

Please use the Feedback Hub (requires Windows 10) to submit your feedback in the Microsoft Edge category. This site is for web developer and designer feedback only. Other feedback will be closed without action.

“Yes, I’m a web developer or designer with feedback for the Microsoft Edge platform.”

Great! This site is where the Microsoft Edge team collects feature requests from the web developer and designer community in the categories listed to the right. For bugs on existing features, please log an issue on the Issue Tracker.

Your feedback will help us with planning and to better understand how web developers and designers are using the platform. Top standards-based feature requests will also be copied over to status.microsoftedge.com, where you can track its development status.

For the most actionable feedback, please search and up vote for existing suggestions before submitting a new suggestion, and create a separate suggestion per idea. Note that off topic or inappropriate suggestions may be moderated. The Microsoft Edge team will use suggestions as an important input, but there are several additional factors that inform the final roadmap.

A note from our lawyers: Please do not send any novel or patentable ideas, copyrighted materials, samples or demos which you do not want to grant a license to Microsoft. See the Terms of Service for more information.

How can we improve the Microsoft Edge developer experience?

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".
(thinking…)

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

Enter your idea and we'll search to see if someone has already suggested it.

  1. Fully implement the FormData API

    Currently the FormData API is only partially implemented in Edge. Most of the more useful methods are missing including: has(), get(), set(), delete(), entries(), and many others.

    FormData is already fully implemented on the other major browsers (Firefox, Chrome, Safari) - see: https://developer.microsoft.com/en-us/microsoft-edge/platform/catalog/?q=formdata

    • ResizeObserver

      A implementation of the ResizeObserver API would be nice.

        • Support navigator.keyboard.getLayoutMap() API

          An API that returns a map which translates from `KeyboardEvent.code` values into a strings that can be shown to the user to identify each key.

          This is not possible with existing web platform APIs because the value that should be shown to the user depends on the keyboard layouts that the user has installed and active.

          WICG incubation spec: https://wicg.github.io/keyboard-map/

          Note: there is some overlap between this and a previous feature request https://wpdev.uservoice.com/forums/257854-microsoft-edge-developer/suggestions/6508637-uievents-keyboard-query-apis

          The previous request was based on an old proposal that is no longer being pursued in the standards bodies.

          • Asynchronous Clipboard API

            The clipboard spec now has an asynchronous API [2] which is significantly more ergonomic than past clipboard APIs – it avoids various issues that the old document.execCommand("copy") approach had, and is much easier to use:

            navigator.clipboard.writeText("hello world").then(...);

            IE 9/10/11 shipped an unstandardized API for copying text or URLs to the clipboard. Edge shipped an older version of the draft standard clipboard/editing-spec-based-API [1], but it has numerous bugs and inconsistencies [2] that even *make it impossible to tell if the attempted copy action has succeeded*. Existing bugs aren't seeing attention, and it seems likely to me that there are more undiscovered…

            • RegExp Named Capture Groups

              The proposal is in Stage 4, so it will be included in next ECMAScript release. Chrome and Safari have implemented this feature for regular expression. Named groups make regex easier to read when there are many groups.

              See: https://github.com/tc39/proposal-regexp-named-groups

              • Spread operator for object literals

                This feature is currently Stage 3 and is implemented by Firefox stable, Chrome stable, Safari Preview, and Node stable.

                This is really useful for shallow cloning objects:

                let objClone = { ...obj };

                • RegExp Lookbehind Assertions

                      Web Share API landed on Chrome for Android in version 61. It's a neat way of providing native sharing hooks to a web app.

                      • scrollIntoViewOptions support for scrollIntoView

                        It would be great to have enhanced support of scrollIntoView, by supporting scrollIntoViewOptions parameters (already supported by Firefox for example):

                        Can I use: https://caniuse.com/#feat=scrollintoview

                        MDN doc: https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollIntoView

                        It is a really simple and smart web API.

                        • Implement inline replies for web notifications

                          We intend to extend the Notifications API to allow developers to show notifications that let users type a reply within the notification itself, and deliver this reply back to the service worker in the notificationclick event. See the spec change pull request at https://github.com/whatwg/notifications/pull/132 and explainer here: https://github.com/anitawoodruff/inline-notification-replies

                          Edge could implement this using the Windows Action Center APIs for specifying a 'quick reply text box' in notification toasts: see https://docs.microsoft.com/en-us/windows/uwp/design/shell/tiles-and-notifications/adaptive-interactive-toasts#inputs

                          • Async Generators / Async Iterators

                            Async iterators and async generator functions(https://github.com/tc39/proposal-async-iteration) are now a stage-3 ECMAScript proposal, nearly finished. They make many styles of programming in JavaScript easier (https://ponyfoo.com/articles/javascript-asynchronous-iteration-proposal); in particular, they are important for WHATWG Streams (https://streams.spec.whatwg.org). As of 2017-10-22, async generators have already been implemented in Blink, Firefox, and WebKit.

                                • "(input[type=file] element).files = dataTransfer.files" fails in Edge

                                  We fail to pass "dataTransfer.files" of DragEvent to "files" property of the input[type="file"] element in Edge. For example:

                                  HTML:
                                  <input id="fileItem" type="file">

                                  Javascript:
                                  var myfiles = dataTransfer.files;
                                  document.getElementById('fileItem').files = myfiles; //This fails in Edge, but no errors are shown in console

                                  Steps to Reproduce a Bug:
                                  https://jsfiddle.net/vth82jst/2/

                                  1. Drag & drop your file to input[type="file"] area
                                  2. Check the "drop file name" and "input value"
                                  3. Even if we drop a file, the "input value" does not change in Edge (It remains "ファイルは選択されていません" unchanged).

                                  I am troubled when I want to select files by drag & drop in Edge.
                                  This…

                                        • WebVR : Add support for Oculus Rift, OpenVR and OSVR

                                          WebVR is now supported by the latest version of Edge in the Creator Update and that's amazing. However, it is limited to Mixed Reality Devices and those devices and they are not available. Windows 10 users who already have a VR headset such as a Rift or a Vive, have to use a beta browser to enjoy WebVR.

                                          Please considere to update Edge with at least a support for the Oculus Rift and the Vive. And only if you want to be a super hero, add OSVR support too.
