TL;DR

Custom Handlebars helpers in SuiteCommerce allow developers to streamline template logic by keeping presentation separate from deeper code. This article discusses best practices for implementing these helpers effectively.

How Do You Determine When to Use Helpers?

Before adding custom helpers in SuiteCommerce, it's essential to evaluate whether they are the best approach to achieve your goals. The primary design principle of SuiteCommerce architecture is to maintain a clear separation between the presentation layer (templates) and the underlying business logic.

Should You Create a Helper?

Consider if the required functionality can be implemented within a view or model instead of creating a new helper. If the logic can reside there, it is often better to do so. This helps to keep the codebase clean and manageable.

Global vs. Local Usage

Another important aspect to consider is the scope of the transformation you want to apply. Creating a helper makes the function available globally across different templates. If a helper will be used in only a single instance, modifying the associated view’s context object to perform the transformation there can be a more efficient approach.

Conclusion

In summary, while custom Handlebars helpers can be powerful tools in SuiteCommerce, judicious use and careful consideration of their necessity can lead to a more maintainable and performant application. Always ask yourself if that logic can be better handled within a view or model, or if it’s acceptable to create a globally accessible helper.

Key Takeaways

Assess whether helpers are necessary for your goals in SuiteCommerce.
Keep presentation and business logic separate.
Use helpers judiciously for global needs; opt for context modifications when usage is localized.

Frequently Asked Questions (4)

When should I create a custom Handlebars helper in SuiteCommerce?

You should consider creating a custom Handlebars helper when the desired logic cannot be efficiently implemented within a view or model. It's beneficial when you need to separate presentation from business logic and the function needs to be available globally across templates.

Is it better to use a view’s context object instead of a helper for single-use logic?

Yes, if a transformation or logic is only needed in a single instance, it's more efficient to modify the associated view’s context object rather than creating a helper, as this keeps the codebase simpler and more manageable.

How can I decide if a helper is necessary for my customization goals?

Evaluate if the logic can be handled within existing views or models. If the presentation layer demands separation from business logic and requires a global function, a helper might be necessary. Always consider the scope and reusability of the function when deciding on a helper.

What is a best practice for using custom Handlebars helpers in terms of their scope?

A best practice is to use Handlebars helpers for logic that needs to be globally accessible across templates. For transformations that are limited to a specific use case, handling them in the view's context is a more efficient approach, as it avoids unnecessary global functions.
