Introduction to the Native SDK for Node.js

See the Table of Contents for a detailed listing of the subjects covered in this document. See the Native SDK Quick Reference for Node.js for a brief description of Native SDK classes and methods.

The InterSystems Native SDK for Node.js is a lightweight interface to powerful InterSystems IRIS® resources that were once available only through ObjectScript:

• Call ObjectScript Methods and Functions — call any embedded language classmethod from your JavaScript application as easily as you can call native JavaScript methods.

• Work with Global Arrays — directly access globals, the tree-based sparse arrays used to implement the InterSystems multidimensional storage model.

• Use InterSystems Transactions and Locking — use Native SDK implementations of embedded language transactions and locking methods to work with InterSystems databases.

Versions of the Native SDK are also available for Java, .NET, and Python:

• Using the Native SDK for Java

• Using the Native SDK for .NET

• Using the Native SDK for Python

To learn more about globals, see the following:

• InterSystems IRIS Basics: Globals and Multi-Model Data Access — Explains what globals are and how they can be accessed using a relational model, using an object model, or directly.

• Exploring Multiple Data Models with Globals Opens in a new tab — Provides an online hands-on exercise that lets you try accessing globals in all three ways.

• Using Globals — Describes how to use globals in ObjectScript, and provides more information about how multidimensional storage is implemented on the server.
