ServerResponse Write File Functionality in SuiteScript

TL;DR

The ServerResponse module's writeFile method allows SuiteScript developers to write files directly to HTTP responses, which is crucial for server-side applications. This method enhances how files are managed and served to clients in NetSuite environments.

Overview of the writeFile Method

The writeFile method is part of the http.ServerResponse object in SuiteScript. This functionality is useful when you want to send files from the server to the client's browser efficiently.

Method Description

• Functionality: Writes a file to the HTTP response.
• Returns: This method does not return a value (i.e., void).

Supported Script Types

The writeFile method can be utilized in server scripts. For further reference on script types, consult the SuiteScript 2.x Script Types.

Governance

• Governance: This method has no governance limits, allowing developers to use it without restrictions on usage.

Parameters

The writeFile method accepts an options parameter, which is a JavaScript object. Here’s a closer look at the parameters you can pass:

Note: The file parameter is mandatory, and omitting it will trigger an error.

Error Handling

When utilizing writeFile, be aware of the following potential errors:

• Error Code: SSS_MISSING_REQD_ARGUMENT
  • Message: Missing a required argument: {param name}
  • Thrown If: The options.file parameter is not specified.
• Error Code: WRONG_PARAMETER_TYPE
  • Message: {param name}
  • Thrown If: The value provided for options.file is not a valid file.File object.

Example of Using writeFile

Here’s a syntax example demonstrating how to implement the writeFile method:

1// Add additional code 
2...
3serverResponse.writeFile({
4    file: myFileObj,
5    isInline: true
6});
7...
