What Is NetSuite SuiteScript and How Does It Work?

Among the many options to customize NetSuite, many developers go for SuiteScript. With SuiteScript, developers can tweak forms, workflows, interfaces, and business logic within NetSuite to achieve more complex business requirements.

In this article, let's dive into SuiteScript and explore its features, benefits, and practical uses. If you' are a new user, we'll also walk you through how to create your first script in NetSuite!

What is SuiteScript? NetSuite Programming Language

SuiteScript is NetSuite’s programming language used for extending its functionality. Since it is based on JavaScript, it speaks a language familiar to many developers. They use SuiteScript to write scripts to automate processes, customize forms and workflows, integrate with external systems, and perform various other tasks within NetSuite to accommodate a wide range of business requirements.

How Does SuiteScript Work?

SuiteScript operates by executing scripts based on events that occur within NetSuite.

For instance, you can compose a script that triggers whenever a new purchase order is added to NetSuite. This script could promptly dispatch an email to the approver of the purchase order details.

You can also design scripts to run at specific intervals like daily or weekly. For example, you can write and run a script each day to monitor your inventory levels. If the levels are low, the script could automatically generate a purchase order.

This feature serves to automate a multitude of business processes, including:

• Creating and fulfilling sales orders
• Approval of purchase orders
• Creating invoices
• Auto-emailing customers or vendors
• Managing inventory levels

Getting Started with SuiteScript

If you’re new to SuiteScript, this is the perfect introduction to guide you through the implementation of a basic customization. Once you've followed the steps, the system will show a "Hello, World!" message each time you open a NetSuite task record.

Step 1: Enabling Features

1. Go to Setup > Company > Enable Features.

2. Click the SuiteCloud subtab.

3. Under SuiteScript, check the box for Client SuiteScript.

‍Note: The system displays a window listing the terms of service.

4. If you agree to the terms, scroll to the bottom of the window and click I Agree.

5. Click Save.

Step 2: Creating the Script File

1. Next, create a script file called helloWorld.js. 

2. For practice purposes, you can either copy the full SuiteScript code from here into a text file and save. 

Step 3: Uploading the Script File to NetSuite

Once you've created your entry point script file, it's time to upload it to your NetSuite File Cabinet. To upload the script file:

1. Navigate to Documents > File > SuiteScripts.

2. On the left pane, choose the SuiteScripts folder and click Add File.

3. Follow the prompts to locate the helloWorld.js file on your local environment and proceed with the upload.

Step 4: Creating a Script Record and Script Deployment Record

It's necessary to specify the record type on which this script should operate. To accomplish this, you need to create the script deployment record by:

1. Go to Customization > Scripting > Scripts > New.

2. In the Script File dropdown list, select helloWorld.js.

3. After you have populated the dropdown list, click the Create Script Record button.

4. Fill out the required body fields as follows:

• In the Name field, enter Hello World Client Script.
• In the ID field, enter _cs_helloworld.

5. Click the Deployments subtab to create the deployment record.

6. Add a line to the sublist, as follows:

• Set the Applies to dropdown list to Task. If you want the dialog to appear when a different type of record loads, select another record type from the list.
• In the ID field, enter _cs_helloworld.

7. Leave the other fields set to their default values. 

8. Click Save.

Note: The Status field is configured as Testing. This setting indicates that the script isn't deployed for other users. 

Step 5: Test the Script

Now that the script is deployed, you should verify that it executes as expected. 

To verify that the dialog alert appears when it should:

1. Go to Activities > Scheduling > Tasks > New to open a task record.

2. If the script is working properly, the system displays a dialog alert.

3. Confirm and close the dialog by clicking OK.

To verify that the expected log entry has been saved to the script deployment record:

1. Go to Customization > Scripting > Script Deployments.‍

2. Click View on your deployment.

3. Click the Execution Log subtab to show an entry similar to the following:

Now that you have deployed your first script, you can experiment with other NetSuite script samples. Another commonly used script type is the user event script. This type is designed for server scripts that should execute when users take certain actions with records.

Best Practices for Script Development

Developing NetSuite scripts requires adherence to best practices. Here are some key best practices for NetSuite script development:

Modularization

Break down NetSuite scripts into smaller, reusable modules to promote code reuse and maintainability. 

Error Handling

Implement robust error handling mechanisms to catch and handle exceptions gracefully. You can use try/catch blocks to handle errors and provide informative error messages for debugging purposes.

Governance Management

Monitor and manage script governance units (governance points and usage units) to prevent script failures due to exceeding governance limits. Use nlapiGetContext().getRemainingUsage() to monitor governance usage and optimize script performance.

Performance Optimization

Optimize script performance by minimizing script execution time and resource consumption. Use efficient algorithms, avoid nested loops, and limit unnecessary API calls to conserve governance units.

Code Review and Testing

Conduct thorough code reviews to ensure code quality. Perform comprehensive testing, like unit tests, integration tests, and user acceptance tests, to validate script functionality.

SuiteScript 2.x vs 1.0: A Detailed Comparison

Code Management and Organization

SuiteScript 1.0: Limited Modularity

SuiteScript 1.0 lacked built-in support for modularity and encapsulation. Developers had to manually organize their code and manage dependencies, often leading to monolithic scripts that were difficult to maintain and debug.

SuiteScript 2.x: Module-Based Architecture

SuiteScript 2.x adopts a modular architecture based on CommonJS modules. Developers can encapsulate script logic within modules and define explicit dependencies between modules using the define function. This promotes code reusability, readability, and maintainability, allowing developers to manage complex applications more effectively.

Dependency Management: Simplifying Complexities

SuiteScript 1.0: Limited Dependency Resolution

SuiteScript 1.0 lacked built-in dependency resolution mechanisms, requiring developers to handle dependencies manually. This often resulted in complex scripting workflows and increased the likelihood of errors and runtime issues.

SuiteScript 2.x: Explicit Dependency Declaration

SuiteScript 2.x encourages explicit dependency declaration, where each module specifies its dependencies upfront. This ensures that dependencies are resolved in a predictable and consistent manner, reducing the risk of dependency conflicts and runtime errors.

Syntax and Programming Behavior

SuiteScript 1.0: Functional Programming

SuiteScript 1.0 primarily follows a functional programming paradigm, where functions are first-class citizens and can be passed as arguments or returned from other functions. This approach is well-suited for simple scripts and procedural workflows.

SuiteScript 2.x: Object-Oriented Programming (OOP)

SuiteScript 2.x embraces object-oriented programming principles, allowing developers to define custom classes, methods, and properties. This enables developers to create more structured and maintainable code, with better encapsulation and abstraction of data and functionality.

Enhanced Functionalities and Capabilities
