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".

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.

  1. 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 };

          • 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.

              • 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.

                      • Support "wheel" events for 2-finger scrolling on Precision Touch Pads (like every other browser does, and every other trackpad does)

                        Microsoft Edge is the only browser that doesn't support 2-finger scrolling properly. Sure, it scrolls the web page, but it doesn't fire wheel events. It instead just lets the OS handle it. This breaks critical functionality not only on the web, but also in many Windows 10 apps that are built using js/html (which is executed by the Edge engine). The biggest example is Flipboard, which doesn't let you "flip" through pages using the scroll gesture on the precision trackpad that Microsoft's own Hardware ships with (every Surface Pro / Book for the past 3+ years).

                        To verify the problem,…

                        • Next Billion Users.

                          The average website is at least 2MB in size. This does not bode well for the next billion users. Users who are coming online for the very first time. Users who come online with sub optimal 2G connections. They miss out on all the benefits of the internet.

                          Javascript libraries and frameworks add to the bloat. Instead of having each page download and use the Js files. Can a js framework be built into the browser itself. We can consider the browser to be a platform. Also, considering that a JS engine isn't enough. A step further will be highly…

                          • auxclick event for non-primary buttons

                            Chrome and FireFox have shipped a new event for non-primary button click action. It is called 'auxclick'. Its specification is written in this WICG github repo.
                            https://wicg.github.io/auxclick/

                            For example prevent defaulting an "auxclick" event with button==1 prevents opening a new tab if the clicked node is a link.

                            • "object not iterable" error message for spread operators

                              Currently attempting "for <var> of" on a object without an iterator would yield a "Object doesn't support property or method 'Symbol.iterator'" error message, while using the spread operator on the same object would only generate a "Function expected" message, giving developers a hard time figuring out what's going on. Edge should improve on this error reporting.

                              • Support PBKDF2 in WebCrypto API

                                While Edge supports WebCrypto API, the PBKDF2 algorithm (see https://www.w3.org/TR/WebCryptoAPI/#pbkdf2) is unsupported. Gecko and Chromium support this algorithm and allow fast key derivation - for all the applications where you don't want to share your master key but only derived task-specific keys.
