Best Practices for the ServiceNow Developer Instance

• Make Brief Statements

Keep in mind that engineers with less experience may use the coding in the future. Make it
as simple as you can. In essence, code optimization is the compiler’s job, negating the need for devious methods.

• Create compact, modular parts

It’s a good idea to segment your program into modules or support functions. The Include Script routines provide excellent examples of this idea. Script Includes being efficient places to store code that can be accessed by business requirements, user interface actions, and scripting actions found in other server-side programs.

• Create repeatable functions

If you observe that a method often uses the same or similar logic, you might want to think about building a special function. This improves the software’s quality, reduces the requirement to find a mistake among numerous blocks of similar code, and makes code easier to manage.

• Utilize Variables to Save Function Results

Stay away from situations when the same function is called again and gives the same result. When functions are called without arguments, this frequently happens. The performance of a function may suffer with repeated calls.

Instead of repeatedly invoking the same function, preserve values in a descriptor variable and link to the variable wherever possible. Additionally, the use of variables could make the code easier to understand.

• Use the Eval Function sparingly

When an input is evaluated or executed, the eval() method returns the outcome. Since line counts are not provided when an error occurs, improper use of eval() exposes your code to SQL injections and makes debugging more challenging.

• Get Rid of Complex Query on Massive Datasets

Reduce the number of times you search through large tables. Performance issues with certain queries could arise as your session lengthens. When data is provided to the inquiry form, let’s say you need to search the CMDB for the relevance of all downstream services connected to a single server.

Executing a scan on the Dependency table is easy for a simple CMDB with just a few hundred or thousand CIs. On the other hand, a CMDB with 3 million CIs and thousands of links may require hours to complete the query.

• Perform a test in a sandbox

A future catastrophe can result from testing out novel code concepts or ideas in a development environment. It’s likely that unfavorable changes will be included in the updated set and spread to more instances when you make adjustments and then modify your method while using an updated set.
