Solve NPM | npm.io

solve

Recursively converts asynchronous data into static data.

Usage

var solve = require('solve');

var stream = solve(data, function (result) {
	// called immediately, and whenever promises resolve or callbacks are called
});

// can add other listeners later
stream(function (result) {
	// do something
});

// can chain additional streams
var downstream = stream(function (result) {
	return result + 1;
});

downstream(function (newResult) {
	// do something
});

// later, when we don't want downstream to call callbacks anymore
downstream.destroy();

Example

var solve = require('solve');

var data = {
	foo: function(callback) {
		setTimeout(function () {
			callback('dynamic');
		}, 1);

		return 'static'
	},
	nested: function () {
		return function () {
			return function () {
				return 'deep';
			}
		}
	},
	merge: solve({
		promise: new Promise(function(resolve){
			resolve('done');
		})
	})
};

solve(data, function(data) {
	console.log(data);
});

This will output:

{ foo: 'static', nested: 'deep', merge: { promise: undefined } }
{ foo: 'static', nested: 'deep', merge: { promise: 'done' } }
{ foo: 'dynamic', nested: 'deep', merge: { promise: 'done' } }
