Modifying Record values based on a specific property's conditions

I am looking to create a filtering system with various filters, each consisting of a label, value, and sometimes the options variable. The inclusion of the type property is intended for differentiation.

However, I have encountered an issue with the following code:

// TypeScript interface definitions...

The problem arises when checking the value of filters.swi.value, which always returns false. How can I ensure that it remains a boolean type as defined in the Filters structure?

Attempting a simple conversion using as Filters results in loss of IntelliSense for the filters variable and transforms the value property into a union type of boolean | string | string[].

An explicit cast like as SwitchFilter raises an error due to 'variable label not being part of type SwitchFilter.'

Is it feasible to achieve this without directly casting the variable or should I consider an alternative approach?

EDIT

With my Plugin class containing a filter object and a search method, every instance of Plugin will have its own set of filters, requiring robust IntelliSense integration.

// TypeScript interfaces and classes definition...

In order to enhance IntelliSense within the search method based on individual filter values, I am seeking a solution that automatically assigns correct types to each filter item without manual conversions everywhere.

A tentative conditional logic utilizing:

// Conditional logic snippet...

and implementing the specific handling only in the search() method as:

Answer №1

When the situation is already fixed, like what you have, then the value of filters.swi.value will be set to false. This is actually a positive thing because it indicates that there is no expected change in this scenario.

If you prefer the value false to be treated as a boolean, you can explicitly specify that: false as boolean. Rest assured, within your current configuration, this conversion will only apply to data of type boolean. Any attempt to assign a different data type will result in an error message.
