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});
