ServerResponse writeLine Method in SuiteScript 2.x

The writeLine() method is a powerful feature in SuiteScript that enables developers to output information (text, XML, HTML) directly to the server response. By leveraging this method, scripts can effectively communicate with the client browser, thereby enhancing the user experience.

Method Description

The writeLine() method is designed to write output information to the response and it functions without returning any value (void).

Supported Script Types

• Server scripts are the only script type that supports this method.

Governance

• There are no governance limits associated with this method, making it a flexible option for server-side scripting operations.

Parameters

• The options parameter is a JavaScript object that is required for this method to function properly.

Errors

The following errors may occur when using writeLine():

• SSS_MISSING_REQD_ARGUMENT: This error is thrown if the options.output parameter is not specified in the function call.
• WRONG_PARAMETER_TYPE: This error occurs if the value passed to options.output is not of the type string.

Syntax

An example of how to implement the writeLine() method is shown below:

1// Add additional code 
2...
3serverResponse.writeLine({
4    output: 'this is a sample string'
5});
6...
7// Add additional code

This example demonstrates the fundamental structure of writing output to the server response using SuiteScript.

Key Takeaways

• Proper error handling is essential to avoid SSS_MISSING_REQD_ARGUMENT and WRONG_PARAMETER_TYPE exceptions.
