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

      • JavaScript stepUp / stepDown for number input

        https://www.w3schools.com/jsref/met_number_stepup.asp
        https://www.w3schools.com/jsref/met_number_stepdown.asp

        These are currently not supported by Edge.

        They work fine for range or date input, but someone just missed the most natural use of these methods for number input.

        • 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.

          • Pretty Print of large JS files is broken

            Pretty print no longer works with large JS files in the latest updates. I thought it was completely broken, but for small files it works fine. Please fix, this is making hard to justify using Edge when I can't debug.

            • 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.

                  • Implement the Broadcast Channel API

                    BroadcastChannel offers a way for all scripts, regardless of window/frame/tab/worker context, to communicate with each other via messaging, similar to MessageChannel.

                    A message sent via BroadcastChannel is delivered to all environments running with the same origin as the sender.

                                  The Network Information API provides information about the system's connection, which is in term of general connection type (e.g., 'wifi', 'cellular', etc.). This can be used to select high definition content or low definition content based on the user's connection. The entire API consists of the addition of the NetworkInformation interface and a single property to the Navigator interface: Navigator.connection.

                                      • Implement a stable algorithm for Array.sort

                                        Change your implementation of Array.sort to be stable.

                                        Edge is now the only browser vendor that does implement a stable sort. Chrome recently switched their sort to be stable. (https://stackoverflow.com/a/52151900)

                                        Use case: A stable sort is really important for browsers because so much of what they're sorting is for UI display purposes. Users don't like it when sorting a grid by a certain column and "equal" rows randomly resort if the grid decides to resort them.

                                          A implementation of the ResizeObserver API would be nice.

                                          Explainer: https://github.com/WICG/ResizeObserver/blob/master/explainer.md
                                          Spec: https://wicg.github.io/ResizeObserver/

                                          Thanks!
