Develop WasmEdge Plug-in
This chapter is WORK IN PROGRESS.
WasmEdge provides a C++ based API for registering extension modules and host functions. While the WasmEdge language SDKs allow registering host functions from a host (wrapping) application, the plugin API allows such extensions to be incorporated into WasmEdge's own building and releasing process.
The C API for the plug-in mechanism is under development. In the future, we will release the C API of plug-in mechanism and recommand developers to implement the plug-ins with C API.
Loadable Plug-in
Loadable plugin is a standalone .so/.dylib/.dll file that WasmEdge can load during runtime environment, and provide modules to be imported.
Please refer to the plugin example code.
WasmEdge Currently Released Plug-ins
There are several plug-in releases with the WasmEdge official releases. Please check the following table to check the release status and how to build from source with the plug-ins.
The
WasmEdge-Processplug-in is attached in the WasmEdge release tarballs.
| Plug-in | Rust Crate | Released Platforms | Build Steps |
|---|---|---|---|
| WasmEdge-Process | wasmedge_process_interface | manylinux2014 x86_64, manylinux2014 aarch64, and ubuntu 20.04 x86_64 (since 0.10.0) | Default |
| WASI-Crypto | wasi-crypto | manylinux2014 x86_64, manylinux2014 aarch64, and ubuntu 20.04 x86_64 (since 0.10.1) | Build With WASI-Crypto |
| WASI-NN with OpenVINO backend | wasi-nn | ubuntu 20.04 x86_64 (since 0.10.1) | Build With WASI-NN |
| WASI-NN with PyTorch backend | wasi-nn | ubuntu 20.04 x86_64 (since 0.11.1) | Build With WASI-NN |
| WasmEdge-HttpsReq | wasmedge_http_req | manylinux2014 x86_64, and manylinux2014 aarch64 (since 0.11.1) | Build With WasmEdge-HttpsReq |
Due to the
OpenVINOandPyTorchdependencies, we only release the WASI-NN plug-in onUbuntu 20.04 x86_64now. We'll work withmanylinux2014versions in the future.
