# ONNX Runtime Node.js API
{: .no_toc }
ONNX Runtime Node.js binding enables Node.js applications to run ONNX model inference.
## Contents
{: .no_toc }
* TOC placeholder
{:toc}
## Usage
Install the latest stable version:
```
npm install onnxruntime
```
Install the latest dev version:
```
npm install onnxruntime@dev
```
Refer to [Node.js samples](https://github.com/microsoft/onnxruntime/tree/master/samples/nodejs) for samples and tutorials.
## Requirements
ONNXRuntime works on Node.js v12.x+ or Electron v5.x+.
Following platforms are supported with pre-built binaries:
- Windows x64 CPU NAPI_v3
- Linux x64 CPU NAPI_v3
- MacOS x64 CPU NAPI_v3
To use on platforms without pre-built binaries, you can build Node.js binding from source and consume it by `npm install <onnxruntime_repo_root>/nodejs/`.
See also [build instructions](../../how-to/build.md#apis-and-language-bindings) for building ONNX Runtime Node.js binding locally.
