What is a plugin in Salesforce?

A plugin is referred to as a built-in interface that helps to process the data. The interface accepts input values and again returns the output back to the flow. Usually, the top-level classes of “Process.Plugin” include:

  • Process.PluginResult
  • Process.PluginRequest and 
  • Process.PluginDescribeResult

JavaScript Quote Calculator Plugin in Salesforce CPQ:

The JavaScript Quote Calculator Plugin (QCP) in Salesforce CPQ helps the Quote Line Editor to:

  • Store maximum values.
  • Calculate the price of all the components.
  • Boost the configurations of existing Salesforce CPQ pricing.
  • Complex and conditional logic or ease the guidelines of complicated product-bundling.
  • Flexibility in managing fields and pricing.

Quote Calculator Plugin Guidelines:

The key guidelines to be followed while planning “Quote Calculator Plugin” scripts are as follows:

Usually, in JavaScript, a “Promise” is an object that allows asynchronous programming in the browser. Also, promises delay a specific action until another action is completed. They support a method “. then(success, failure),” where success means resolving a promise and failure means rejecting the promise. In the plugin, if you want to do any asynchronous programming like “server callout,” then you’ve to return a promise that resolves after the action is completed. It ensures that the steps for calculation occur in the proper way. If you find any method that doesn’t need asynchronous behavior, then you can return a promise that immediately resolves as “return Promise.resolve();”. Promises help resolve a value that passes as one of the parameters to “.then()” callbacks. In your code, you can use this fact, but one thing must be remembered that the promises aren’t required to resolve to a value.

Quote Calculator Plugin Methods:

There are seven “Quote Calculator Plugin Methods.”, here is the list:

Quote Calculator Plugin Methods
  1. oninit: Calls before formula fields are evaluated.
  2. onBeforeCalculate: Calls before calculation begins, but after evaluating formula fields.
  3. onBeforePriceRules: Calls before calculator evaluates price rules.
  4. onAfterPriceRules: calls after the calculator evaluates price rules. 
  5. onAfterCalculate: calls after it completes a calculation but before the formula fields re-evaluation.
  6. isFieldVisible: calls after the calculator completes the calculation.
  7. isFieldEditable: calls after the calculator completes the calculation.
