Imagine I have the following scenario:
interface Validator {
validate: (value: string) => boolean;
errorMessage: string;
}
interface EditDialogField {
label: string;
prop: string;
required?: boolean;
type: 'input';
validators?: Validator[];
}
Having IntelliSense suggestions when using these interfaces is convenient, but I am interested in adding comments that will also appear in IntelliSense, particularly in VS Code. Can this be achieved?
Understood!
interface EditDialogField {
/** Description of label */
label: string;
/** Description of prop */
prop: string;
required?: boolean;
type: 'input';
validators?: Validator[];
}
To make it visible on hover in your editor, my suggestion is to document the interface and utilize the @field within the documentation comment.
Alternatively, you might consider using @member as it may provide better syntax-highlighting for the documentation.
/**
* Description of the EditDialogField interface
*
* @interface EditDialogField
* @member {string} label - used for specific purpose
* @field {string} prop - used for different purpose
*/
interface EditDialogField {
label: string;
prop: string;
required?: boolean;
type: 'input';
validators?: Validator[];
}

Expanding on the insights shared by @Ronan Quillevere and @ffxsam,
Ronan's method demonstrates how information can be displayed in VSCode when hovering over the interface, as highlighted in his comments.
However, in the example below where that interface is utilized, hovering over the destructured variables in the final line does not showcase the documentation from the member/field tag, but rather from the comment within the interface, as suggested by ffxsam.
/**
* Description of the interface
*
* @interface EditDialogField
* @member {string} label - Used for a specific purpose
* @field {string} prop - Used for another purpose
*/
interface EditDialogField {
/** Documentation within the interface */
label: string;
prop: string;
required?: boolean;
type: 'input';
}
const dialog: EditDialogField = { label: 'label', prop: 'prop', type: 'input' };
const { label, prop } = dialog;
