Say I have the following:
interface Validator { validate: (value: string) => boolean; errorMessage: string; } interface EditDialogField { label: string; prop: string; required?: boolean; type: 'input'; validators?: Validator[]; }
This is useful, as IntelliSense pops up suggestions when I use these interfaces, but I'd like the ability to add comments that also show up in IntelliSense (specifically VS Code). Is this possible?
Documenting an interface consists of naming and identifying it and documenting its syntactic and semantic information. The first two parts constitute an interface's "signature." When an interface's resources are invokable programs, the signature names the programs and defines their parameters.
A TypeScript Interface can include method declarations using arrow functions or normal functions, it can also include properties and return types. The methods can have parameters or remain parameterless.
Interfaces in TypeScript have two usage scenarios: you can create a contract that classes must follow, such as the members that those classes must implement, and you can also represent types in your application, just like the normal type declaration.
To define an interface for an array of objects, define the interface for the type of each object and set the type of the array to be Type[] , e.g. const arr: Employee[] = [] . All of the objects you add to the array have to conform to the type, otherwise the type checker errors out.
Got it!
interface EditDialogField { /** Explain label here */ label: string; /** Explain prop here */ prop: string; required?: boolean; type: 'input'; validators?: Validator[]; }
