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".

  1. Enable JS debugging from VS for Edge

    I was shocked to find that VS 2015 can't debug JS running in Edge (yet it can debug WWAs using EdgeHTML?). I hope this will be fixed soon, but it means that IE 11 is the only option for end-to-end debugging in VS, which is unfortunate.

    • USB API

      Google is working on an usb api for Chrome, it would be awesome if Edge did that as well.

      • Webcrypto support

        Right now Edge and Safari are the only two browsers that do not support WebCrypto properly. With the depreciation of <KeyGen> and ActiveX the this is even more important than before. You can see : http://pkijs.org/ as an example of how this can be used to enable many of the same scenarios without the need for plug-ins. This is a great site to see what support looks like in each browser - https://diafygi.github.io/webcrypto-examples/

          • Support window.navigator.registerProtocolHandler()

            Add support for custom protocols registered through registerProtocolHandler().

            This enables basic interoperability between different web services.

            More info at: https://developer.mozilla.org/en-US/docs/Web/API/Navigator/registerProtocolHandler

            • JavaScript UUID Support

              I'd love to have the ability to generate UUIDs in javascript via an API the browser supports to generate real UUIDs from the host machine vs having to generate them server side. Would this be possible?

              Possible functionality could work as such:

              var uuid = UUID.randomUUID();
              var uuid2 = new UUID(uuid);
              var uuid3 = new UUID("de305d54-75b4-431b-adb2-eb6b9e546014");

              Following https://tools.ietf.org/html/rfc4122.

              • Show correct window.orientation at web page startup

                For now IE mobile 11 shows window.orientation == 0 even when device is in landscape position. The value is correct after 'orientationchange' event but not before first firing of that event (at page startup).

                Plz fix that in new browser ;)

                  • Remove 'undefined' altogether from JavaScript

                    Only keep 'null'. The use of a "strict mode level 2" might be necessary.

                    It is the root of a lot of complication. It forces you to check both 'undefined' and 'null' when checking if a variable is set.

                    I can't find a single use case where it proves useful.

                    Doug Crockford publicly said he thinks it was a terrible idea.

                    • Implement arguments.callee.caller.name

                      The object arguments.callee.caller.name returns the name of the function that called the current function; critical to debug a commonly called function if you need to know WHERE it was called from. Chrome, Firefox and (real) Opera have supported this for years.

                      • Add async versions of common Array methods

                        With the inclusion of the Promise object in sight, it's time to push for the creation of methods such as :

                        Array.everyAsync()
                        Array.filterAsync()
                        Array.findAsync()
                        Array.forEachAsync()
                        Array.mapAsync()
                        Array.reduceAsync()
                        Array.someAsync()

                        And the like...

                                  • Gamepad API: Support Gamepad Vibration & Force Feedback effects

                                    There is the proposed Gamepad API http://caniuse.com/#search=gamepad in development, however the specification does not have any planned means of utilizing vibration in gamepads.

                                    It is a rather basic feature that enhances the gaming experience.
                                    There should be a recommendation for it or prefixed functionality for IE. A complementary function to the API like myGamepad.setVibration(leftMotor, rightMotor) would be ideal.

                                    In the future I'd also like to see a way to have force feedback effects for devices that support them, like Joysticks and Steering Wheels which would be useful for simulators and medical applications.

                                    Thanks in advance!

                                    • Transferable for postMessage in Web Worker

                                      The postMessage API for Web Workers in Chrome and Firefox supports a "Transferable" interface allowing certain types of objects such as ArrayBuffers and Typed Arrays to be "moved" from a worker context to the parent context, or vice-versa, without copying.

                                      This can be essential for good performance in image and video-processing tasks that need to ship around megabytes at a time.
