spawn-generator

Write the synchronous-like code with promises and generators

Example

const spawnGenerator = require('spawn-generator');

const asyncFunction = function (fruit) {
  return Promise.resolve(fruit);
};

const generatorFunction = function*(fruit) {
  let fruits = [];
  fruits.push(yield asyncFunction('apple')); // function "asyncFunction" returns Promise, see above
  fruits.push(yield asyncFunction(fruit));
  return fruits;
};

const functionToCall = spawnGenerator(generatorFunction);

functionToCall('banana')
  .then((fruits) => console.log(fruits)); // outputs ['apple', 'banana']

// immediately execute generator function when passing more than one parameter to spawnGenerator
spawnGenerator(generatorFunction, 'orange')
  .then((fruits) => console.log(fruits)); // outputs ['apple', 'orange']
