Exploring the potential of utilizing dynamic types in a TypeScript React application alongside React Hook Form

Currently, I am in the process of converting a React application that was previously not using TypeScript to now incorporate TypeScript. I am facing an issue with the use of React Hook Form's setValue method.

The component I am working on serves as a reusable container for data grid filters passed in as children. The values of the React Hook Form fields are read and written dynamically to and from a cache, causing the component to be unaware of the type of the field values object.

In the non-TypeScript version, I had no issues with this setup, as I could pass dynamic field names and values to setValue using the non-generic implementation of useForm.

However, with TypeScript, the definition of setValue looks like this:

(property) setValue: <never>(name: never, value: never, options?: Partial<{
   shouldValidate: boolean;
   shouldDirty: boolean;
   shouldTouch: boolean;
}> | undefined) => void

The never type generic restricts me from providing a dynamic value (of type string) as the field name as shown below:

fields.forEach((field, i) => formMethods.setValue(field[0], field[1], { shouldDirty: true }));

As a result, I am encountering the error: Argument of type 'string' is not assignable to parameter of type 'never'

I am aware that in normal circumstances, I would define a type for the field values object and pass it as a generic to useForm. However, I am unsure how to handle dynamic types instead. Any suggestions?

Answer №1

To address this issue, I resolved it by importing the Type UseFormProps from React Hook Form and assigning it to the generic Form Options property in the following manner:

interface FormProps {
    formOptions: UseFormProps,
    ...
};

const FilterForm = ({
  formOptions,
  ...
} : FormProps) => {

const formInstance = useForm(formOptions);

As a result, the definition of the setValue method was updated to:

(property) setValue: <string>(name: string, value: any, options?: Partial<{
  shouldValidate: boolean;
  shouldDirty: boolean;
  shouldTouch: boolean;
}> | undefined) => void
