A peek into the WebAssembly Browser Preview

Following the introduction of asm.js, we have been working with other browser vendors including Mozilla, Google, Apple, along with the rest of the WebAssembly community group, to push the performance boundary of the web with WebAssembly. WebAssembly is a new, portable, size- and load-time-efficient binary compiler target, which promises near-native performance on the web.

As the community group comes close to consensus over the final design of the MVP (minimum viable product) release, we are pleased to share that the WebAssembly standard is in browser preview and invite the community to provide feedback on the WebAssembly design. We’re continuing to make progress towards a public preview implementation in Microsoft Edge, and today we’re excited to demonstrate WebAssembly in our internal builds.

The Browser Preview

The WebAssembly browser preview is effectively a release candidate for MVP, and includes the latest:

Binary format, generalized from previous AST formats to a more efficient stack machine format; a more compact binary format generally means better loading time.

Equivalent human-readable text format for the purpose of reading, debugging, and occasionally handwriting WebAssembly.

Built-in JavaScript APIs to integrate WebAssembly modules to the web platform.

Up-to-date tools to produce WebAssembly modules, such as the Emscripten /Binaryen toolchain to convert C++ source to asm.js to WebAssembly, and WABT to convert between text and binary format.

To give you a taste of what WebAssembly looks like now, here is an example C++ recursive factorial function with its corresponding WebAssembly:

[table][tr]C++ factorial WebAssembly factorial function body binary | text [/tr] [tr][td]int factorial(int n) { if (n == 0) return 1; else return n * fac(n-1); }[/td] [td]20 00 | get_local 0 42 00 | i64.const 0 51 | i64.eq 04 7e | if i64 42 01 | i64.const 1 05 | else 20 00 | get_local 0 20 00 | get_local 0 42 01 | i64.const 1 7d | i64.sub 10 00 | call 0 7e | i64.mul 0b | end[/td] [/tr] [/table]
The WebAssembly factorial function is extracted from the WebAssembly spec test.

We are eager to hear feedback from the community on WebAssembly. App authors should still expect changes and recompilation of apps for the MVP release, but any feedback from developing an app during the preview will help us make a better standard.

Implementation Progress in Microsoft Edge

We’ve been hard at work developing support for WebAssembly in Microsoft Edge at the open-source ChakraCore project repo. Microsoft Edge and ChakraCore are close to shipping the browser preview, which we expect to come when the full JavaScript APIs are implemented.

To demo the current capability of ChakraCore, we are also excited to showcase the AngryBots demo (with an updated WebAssembly binary) running in an internal build of Microsoft Edge. The demo loads faster than earlier versions compiled to asm.js or older WebAssembly formats, due to a more compact binary and ChakraCore’s new ability to defer parsing WebAssembly functions.

Over the next couple of months, our team will be focused on bringing the browser preview to Microsoft Edge. We look forward to continuing to contribute to the standardization of WebAssembly with the other browser vendors and the community, and would love to hear your thoughts about WebAssembly via @MSEdgeDev and @ChakraCore, or on the ChakraCore repo.

reinstall store app windows 10

The following command reinstalls all apps in Windows:

Open Start Menu and type powershell.right-click on PowerShell and select "Run as Administrator" option.

Then Enter the following command that will reinstall all the modern apps in Windows :

Get-AppxPackage -allusers | foreach {Add-AppxPackage -register "$($_.InstallLocation)\appxmanifest.xml" -DisableDevelopmentMode}

Click to expand...

Did not work for me. I troed it 3 times, allways got an error.

Hi Fernando,

These are the steps to resolve the issue with Windows Store app itself. For better assistance, we suggest creating a new thread about Windows 10 apps installation.

Regards.

WebAssembly support now shipping in all major browsers

While Mozilla has been preparing to launch Firefox Quantum, its fastest browser yet, some notable developments have happened with WebAssembly, the binary file format (“wasm”) that works with JavaScript to run web applications at near-native speeds.

In the past weeks, both Apple and Microsoft have shipped new versions of Safari and Edge, respectively, with support for WebAssembly. Since Mozilla Firefox and Google Chrome already support WebAssembly, that makes all four major browsers capable of running code compiled to the wasm format on the web.

“Google, Apple, and Microsoft had all committed to supporting WebAssembly in their browsers. To have that support in market today is a really exciting development,” said Luke Wagner, the Mozilla engineer who created WebAssembly’s precursor, asm.js, and spearheaded work on the WebAssembly specification.

For developers, broad client support means they can experiment with WebAssembly with assurance that most end users will be able to run super-fast wasm modules by default. Ubiquitous client support fueled the early success of asm.js. Since it is a pure subset of JavaScript, asm.js can run in any browser without modification. For instance, you can find asm.js on Facebook, where it powers popular games like Candy Crush Saga, Top Eleven, and Cloud Raiders.

A Growing Standard

What’s the big deal about WebAssembly? First, it’s on its way to becoming an industry standard. It’s a proven way to run large, complex applications on the web. And it gives web developers a number of options they’ve never had before. For instance, now you can:

Take advantage of the compact wasm format to transmit files quickly over the wire and load them as JavaScript modules

Get near-native performance without using a plug-in

Write code that is both performant and safe, because it executes within the browser’s security sandbox

Have a choice of languages besides JavaScript, using WebAssembly as a compiler target for C and C++, with additional language support to come.

How It’s Used Today

WebAssembly has caught the interest of a wide swath of technical folks, because it brings predictable performance to the web platform — something that’s been exceedingly difficult to achieve with JavaScript alone. Gaming companies were early adopters of WebAssembly and asm.js. Epic and Unitywere first to put their industrial-strength game engines on the web without rewriting the C++ code bases in JavaScript.

Today, the use cases for WebAssembly and asm.js have grown beyond online gaming. As people experiment with the process of using the WebAssembly format and its cohort, the Emscripten compiler, they’re finding ways to move increasingly sophisticated applications to the web. Things like:

Co mputer vision

3D mapping – Altus platform, Google Earth

User-interface design

Language detection

Audio mixing

Video codec support

Digital signal processing

Medical imaging

Physical simulation

Encryption

Compression – zlib-asm, Brotli, lzma

Computer algebra

“Asm.js and WebAssembly were really no-brainers for the gaming industry, because they had all this investment in massive C++ programs that they didn’t want to rewrite for the web,” Wagner said. “Now we’re seeing people using WebAssembly for all kinds of new projects. So there’s this real promise that we will someday be able to run most any application on the web and have it perform just as it would if it were running locally on your PC.”

Want to learn more about WebAssembly? Developers can find resources on MDN Web Docs and on the WebAssembly.org project site.

Interactive Tools

You can also try out WebAssembly Explorer, an online tool which allows you play around with a C/C++ compiler and understand how WebAssembly code is produced, delivered, and ultimately consumed by the browser. Another online tool, WebAssembly Fiddle, lets you write, share, and run WebAssembly code snippets in the browser. For an even deeper dive, you can inspect WebAssembly binaries to understand how WebAssembly code is encoded at a binary level.
