f-async-resolver

Make your functionas async.

This module is made so you can make your funcions async and return a value without the need of having it in the same function. For example returning an answer from a server in a WebSocket connection.

Installing

npm i f-async-resolver

Initializing

const async = require('f-async-resolver').resolver;
const resolver = new async();

Examples

Awaiting for a Number

const async = require('f-async-resolver');
const resolver = new async.resolver();
function number() {
    return new Promise(solver => {
        resolver.await('number', solver);
    });
}

number.then(number => {
    console.log(number);
});

setTimeout(() => {
    resolver.resolve('number', 15);
}, 1000);

/*
Output (1 Second after running the Code) 
> 15
*/

Awaiting for WebSockets message.

const async = require('f-async-resolver');
const resolver = new async.resolver();
const WebSocket = require('ws');


class database {
    constructor(IP) {
        this.ws = new WebSocket('ws://127.0.0.1:4000');  // Connects to a Server.
        this.ws.onopen = this.onopen.bind(this);         // Simple function Bind.
        this.ws.onmessage = this.onmessage.bind(this);   // Simple function Bind.
    }
    onopen() {
        console.log('Connected!');
    }
    get() {
        return new Promise(solver => {                  // Returns a Promise and makes 'solver' to solve.
            this.ws.send({
                type: 'getDatabase'
            });                                          // Sends a message to the Server
            resolver.await('getDB', solver);             // Sets label and function to Solve.
        });
    }
    onmessage(msg) {
        resolver.resolve('getDB', msg);                  // Solves 'getDB' label with msg value.
    }
};

const connection = new database('ws://127.0.0.1:4000');
connection.get().then(msg => {
    console.log('Awaited for ' + msg);                   // Shows the message Recieved.
});
