SuiteScript Overview
NetSuite’s SuiteScript scripting language provides full-featured application-level scripting capabilities that support sophisticated procedural logic on both the client and server sides. You can use SuiteScript to extend NetSuite and customize, search for, and process your NetSuite data. A SuiteScript Debugger is also available for debugging server scripts.
SuiteScript 2.x extends the capabilities of the original SuiteScript offering with an API architecture familiar to JavaScript developers. Highlights of SuiteScript 2.x include:
-
Modularity — supports encapsulation, provides intuitive code organization, and ensures there are no global variable or method naming conflicts.
-
Automatic dependency management — enables you to concentrate on logic instead of dependencies and load order.
-
JavaScript — designed to support most standard JavaScript providing you programmatic access to NetSuite functionality.
-
Third-party JavaScript libraries — use custom modules to load your preferred third-party JavaScript libraries.
-
Enhanced functionality — support for all HTTP content types, SFTP file transfer, data caching, search pagination, flat file streaming, enhanced encryption, decryption, and hashing.
-
Asynchronous client script processing — provides promises and map/reduce scripts; a structured framework for server scripts processing a large number of records
