This repository contains documents describing the design and high-level overview of WebAssembly.
The documents and discussions in this repository are part of the WebAssembly Community Group.
WebAssembly or wasm is a new, portable, size- and load-time-efficient format suitable for compilation to the web.
WebAssembly is currently being designed as an open standard by a W3C Community Group that includes representatives from all major browsers. Expect the contents of this repository to be in flux: everything is still under discussion.
WebAssembly is efficient and fast: Wasm bytecode is designed to be encoded in a size- and load-time-efficient binary format. WebAssembly aims to execute at native speed by taking advantage of common hardware capabilities available on a wide range of platforms.
WebAssembly is open and debuggable: WebAssembly is designed to be pretty-printed in a textual format for debugging, testing, experimenting, optimizing, learning, teaching, and writing programs by hand. The textual format will be used when viewing the source of wasm modules on the web.
Design Process & Contributing
The WebAssembly specification is being developed in the spec repository. For now, high-level design discussions should continue to be held in the design repository, via issues and pull requests, so that the specification work can remain focused.
We’ve mapped out features we expect to ship:
- An initial Minimum Viable Product (MVP) release;
- And soon after in future versions.
