Develop WasmEdge Plug-in
While the WasmEdge language SDKs allow registering host functions from a host (wrapping) application, developers should implement the host functions before compilation. For the other solutions, WasmEdge provides the plug-in architecture to load the plug-in shared library for easier extending of the host functions. With developing the plug-ins, WasmEdge SDKs in the supported languages can load and register the host functions from the plug-in shared libraries.
In current, developers can follow the guides to implement the plug-ins in C API (recommended) or C++.
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

Due to the
OpenVINOandPyTorchdependencies, we only release the WASI-NN plug-in onUbuntu 20.04 x86_64now. We'll work withmanylinux2014versions in the future.
