Wasmer 1.0 Can Run WebAssembly 'Universal Binaries' on Linux, MacOS, Windows, Android, and iOS

The WebAssembly portable binary format will now have wider support from Wasmer, the server-side runtime which "allows universal binaries compiled from C++, Rust, Go, Python, and other languages to run on different operating systems and in web browsers without modification," reports InfoWorld: Wasmer can run lightweight containers based on WebAssembly on a variety of platforms — Linux, MacOS, Windows, Android, iOS — from the desktop to the cloud to IoT and mobile devices, while also allowing these containers to be embedded in any programming language. The Wasmer runtime also is able to run the Nginx web server and other WebAssembly modules... Wasmer was introduced in December 2018, with the stated goal of doing for WebAssembly what JavaScript did for Node.js: establish it server-side. By leveraging Wasmer for containerization, developers can create universal binaries that work anywhere without modification, including on Linux, MacOS, and Windows as well as web browsers. WebAssembly automatically sandboxes applications by default for secure execution, shielding the host environment from malicious code, bugs, and vulnerabilities in the software being run. Wasmer 1.0 reached "general availability status" with its release on January 5, and its developers are now claiming "out of this world" runtime and compiler performance. "We believe that WebAssembly will be a crucial component for the future of software execution and containerization (not only inside the browser but also outside)."
