# Node_API



## Introduction



Node-API is an API used to encapsulate JavaScript capabilities as native plug-ins. It is independent of the underlying JavaScript and is maintained as part of Node.js.

## Supported Capabilities



Node-API eliminates the differences between underlying JavaScript engines and provides a set of stable interfaces.

The NAPI component re-implements the Node-API and connects to underlying engines such as ArkJs. Currently, some interfaces in the Node-API standard library are supported.
