Steps to Optimize a SuiteScript

Optimizing a SuiteScript involves several best practices to ensure your scripts run efficiently and effectively. Here are key steps to consider:

Efficient Use of API Calls

• Batch Processing: Process records in batches rather than one at a time to reduce the number of API calls. Use SuiteScript’s search module to retrieve multiple records in a single call.
• Limit Data Retrieval: Only retrieve the fields you need. Using the columns parameter in searches can limit the data returned, improving performance.

Optimize Search Operations

• Use Saved Searches: Predefine complex searches as saved searches and reference them in your script to save time.
• Reduce Result Sets: Use filters to limit the number of records processed. Apply appropriate filters to narrow down search results to only what is necessary.
• Paginate Results: Use pagination to handle large data sets, retrieving and processing one page of results at a time.

Minimize Client-Side Processing

• Use Client Scripts Judiciously: Offload as much processing as possible to server-side scripts. Client scripts should primarily handle user interactions and validations.
• Asynchronous Processing: For long-running tasks, use asynchronous processing techniques such as setTimeout or Promises to avoid blocking the user interface.

Effective Use of SuiteScript Modules

• Leverage SuiteScript 2.x: Utilize the modular architecture of SuiteScript 2.x for better code organization and reuse. The define and require functions help manage dependencies efficiently.
• Avoid Redundant Module Loads: Ensure modules are only loaded once and reused across your script to save memory and processing time.

Error Handling and Logging

• Implement Robust Error Handling: Use try-catch blocks to handle exceptions gracefully. Log errors for debugging purposes but avoid excessive logging in production environments.
• Use Appropriate Log Levels: Use different log levels (debug, audit, error) appropriately to control the verbosity of logs and minimize performance overhead.

Script Governance

• Respect Governance Limits: Be aware of SuiteScript governance limits and avoid operations that consume excessive usage units. Split heavy operations into multiple executions if needed.
• Scheduled Script Usage: For heavy data processing, consider using Scheduled Scripts or Map/Reduce scripts, which are designed for such tasks and can handle governance limits better.

Optimize User Interface Scripts

• Lazy Loading: Load data only when necessary. For example, load additional data on demand when a user interacts with the UI, rather than loading everything upfront.
• Debounce User Inputs: For scripts reacting to user inputs, use debouncing techniques to limit the frequency of executions and improve performance.

Code Optimization Techniques

• Avoid Deep Nesting: Keep your code flat and avoid deep nesting of functions or conditional statements to improve readability and performance.
• Reusable Functions: Write reusable functions to avoid code duplication, making the codebase easier to maintain and optimize.
• Minify Scripts: For client-side scripts, consider minifying your code to reduce load times.
