flex-value
Strongly-typed, value-resolution handler:
- From a direct value
- From value as a promise
- From a callback that returns the value
- From a callback that returns a promise
With support for generic error handling.
See Wiki for documentation and examples.
Install
npm i flex-value
Usage
import {Flex, FlexValue} from 'flex-value';
// fully-dynamic input/value:
const input: FlexValue<string>; // string | Promise<string> | (() => string | Promise<string>)
// strongly-typed, actual value resolution:
const value: string = await Flex.get(input);
And we can handle all types of errors in a generic way:
const onError = e => {
// any error thrown or promise reject ends up here;
};
const value: string = await Flex.get(input, {onError});
