Component Model design and specification This repository is where the Component Model is being standardized. For a more user-focused explanation, take a look at the Component Model Documentation. This repository contains: high-level goals, use cases, design choices and FAQ docs low-level WIT, text format, binary format, linking, concurrency and ABI docs a growing WAST test suite In the future, this repository will additionally contain a formal spec and a reference interpreter. Milestones The Component Model is currently being developed incrementally as part of WASI "Developer Preview" releases. The Component Model features enabled as part of a WASI Developer Preview release are kept stable by producer and consumer tools so that they can be used outside the browser in production settings to collect real-world feedback. The current WASI Developer Preview releases are: 0.2.0: the first release based on the Component Model; includes shared-nothing and shared-everything linking, a variety of high-level value types, resource types with handles, and WIT. 0.3.0: the first release with native concurrency support in the Component Model and WIT; adds async functions, streams and futures as well as new ABI built-in functions (additions are marked by the 🔀 emoji throughout the repo). 0.3.1: adds the map<K,V> type (🗺️) and the implements and external-id annotations (🏷️). Subsequent WASI Developer Preview releases will include other emoji-gated features such as cooperative threads (🧵).
