+# 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.
