TypeScript definitions for thunky




function thunky

thunky: <TFn extends (callback: (...args: any[]) => any) => void>(
fn: TFn
) => TFn;
  • Delay the evaluation of a paramless async function and cache the result (see [thunk](http://en.wikipedia.org/wiki/Thunk_%28functional_programming%29)).

    If the thunk callback is called with an Error object as the first argument it will not cache the result.

    Parameter fn

    The function to execute.

    Example 1

    import thunky = require('thunky');

    const test = thunky((callback) => { // the inner function should only accept a callback console.log('waiting 1s and returning random number'); setTimeout(() => { callback(Math.random()); }, 1000); });

    test((num) => { // inner function is called the first time we call test console.log(num); // prints random number });

    test((num) => { // subsequent calls waits for the first call to finish and return the same value console.log(num); // prints the same random number as above });
