The `Wasmnizer-ts` now supports a strict subset of TypeScript and continuously strives to accommodate more semantics. There are three components in `Wasmnizer-ts`: - `ts2wasm-compiler`: a compiler for compiling TypeScript source code into WasmGC bytecode. - `ts2wasm-stdlib`: standard library implemented in ts source code, will be compiled with application together. See [standard library](./doc/standard-library/index.md). - `ts2wasm-runtime-library`: runtime libraries for exposing host APIs required for running the generated wasm module, including: 1. `libdyntype`: support dynamic objects, see API spec [here](./doc/libdyntype_api_spec.md). We have proposed a [WASI proposal](https://github.com/WebAssembly/WASI/issues/552). 2. `libstruct-indirect`: access WasmGC struct fields through index calculated during runtime, see API spec [here](./doc/libstruct_indirect_api_spec.md). These APIs are used to emulate the behaviour of the [proposed struct.get/set_indirect opcode](https://github.com/WebAssembly/gc/issues/397). 3. `libstd`: standard library implemented in native, such as `console.log`, see [standard library](./doc/standard-library/index.md). > **Note**: **This project is highly experimental and under active development, DO NOT use in production** ## Features - **garbage collection**. `ts2wasm-compiler` leverage WebAssembly GC proposal, which can benefit from runtime's GC capability. - **optimization**. `ts2wasm-compiler` uses binaryen as backend, which can benefit from binaryen's powerful optimization capabilities. - **small footprint**. Data structures in source code is represented as WasmGC types, which avoids the requirement for `memory allocator` and `garbage collector` inside wasm module. - **static compilation**. Type information in TypeScript source code is used to create static WasmGC types, which avoids the overhead of dynamic type checking. - **dynamic typing**. `any` and other dynamic types in TypeScript source code are supported by host APIs. ## Execution environment The wasm module generated by `ts2wasm-compiler` is designed to be executed in a WasmGC runtime environment. The runtime should provide the following capabilities: - **WebAssembly proposals:** - **[WasmGC](https://github.com/WebAssembly/gc) (mandatory)**: WasmGC proposal, which is a garbage collection mechanism for WebAssembly. > Note: the GC opcode generated by binaryen is slightly different than [GC MVP](https://github.com/WebAssembly/gc/blob/main/proposals/gc/MVP.md), please see [here](https://docs.google.com/document/d/1DklC3qVuOdLHSXB5UXghM_syCh-4cMinQ50ICiXnK3Q/edit#heading=h.9dwoku9340md) for details. - **[Exception handling](https://github.com/WebAssembly/exception-handling) (required by try-catch statements)**: exception handling proposal, which adds exception handling mechanism to WebAssembly. - **[stringref](https://github.com/WebAssembly/stringref) (required by stringref feature)**: reference-typed strings proposal, provide a language independent string representation. - **APIs:** - **[libdyntype API](./doc/libdyntype_api_spec.md) (required by dynamic typing)**: APIs for supporting dynamic objects. - **[libstruct-indirect API](./doc/libstruct_indirect_api_spec.md) (required by `interface` type)**: APIs for accessing WasmGC struct fields through index calculated during runtime. - **libstd API (required by standard libraries)**: APIs for providing standard libraries from host environment. `Wasmnizer-ts` currently implemented host APIs on multiple environments: - [WebAssembly Micro Runtime (WAMR)](https://github.com/bytecodealliance/wasm-micro-runtime/tree/dev/gc_refactor): `libdyntype API`, `libstruct-indirect API` and `libstd API` - chrome browser and nodejs (20.6.1+): part of `libdyntype API` implemented with JavaScript Please see [feature list](./doc/developer-guide/feature_list.md) for supporting status of each feature.
