WebNN-native Binding for Node.js

*WebNN-native Binding for Node.js is a Node.js C++ addon. The implementation is based on WebNN-native C++ API and exposes WebNN JavaScript API.

Prerequisites

Install Node.js.

For Windows, install Visual Studio 2019.

For Linux, install build-essential package.

Verified configurations:

  • Node.js 14 LTS
  • Windows 10
  • Ubuntu Linux 16.04

Build WebNN-native

You need to build WebNN native as a C/C++ library by following WebNN-native README, please make sure the end2end tests can work as expected.

Note: In case you have multiple python installations, you might want to use the --script-executable gn flag to instruct gn to use the python 2.x installation.

Build and Run

Install Node.js modules

Install node-gyp and other Node.js modules that are required to build the Node.js addon. The webnn_native_lib_path must be configured so that WebNN native header files and libraries can be found. The path must be a relative path to the node folder. For example, execute the following command:

> npm install --webnn_native_lib_path="../out/Release"

Build

The Node.js addon can also be built after install. For example, execute the following command:

> npm run build --webnn_native_lib_path="../out/Release"

Test

> npm test
