Introduction

Note: You need Node >= 10.

This repo contains examples for NodeJS. It uses node-addon-api to wrap sherpa-onnx for NodeJS and it supports multiple threads.

Note: ../nodejs-examples uses WebAssembly to wrap sherpa-onnx for NodeJS and it does not support multiple threads.

Before you continue, please first run
