UnsupportedErrorclass

new UnsupportedError(message?: string, options: BaseErrorOptions = {})

Param	Type
`message`	`string`	Optional human-readable description of the unsupported functionality.
`options`	`BaseErrorOptions`	Options for BaseError that provide additional helpful error functionality. Defaults to `{}`
`.caller`	`AnyCaller`	Modify the stack to trim off lines after a certain calling function.

Return
`UnsupportedError`	Error thrown when functionality is called but is not supported — by a backend, an environment, or an implementation.

Error thrown when functionality is called but is not supported — by a backend, an environment, or an implementation.

Thrown when functionality is called but is not supported — a backend that can't run a type of operation (e.g. a key-value store asked to run a query), an environment missing a required capability (e.g. localStorage on the server), or an abstract method left for a subclass to override.

Usage

import { UnsupportedError } from "shelving/error";

class KVProvider {
  getQuery(): Promise<Items> {
    throw new UnsupportedError("KVProvider does not support querying items");
  }
}
