unhell (Powered by kvertex.com)

this is the package to save coders from callback hell.

Understanding

This is the simple solution without using promise or modularization techniques. Simple to write and easy to understand and implement

Example

let unhell = require("unhell")

/*
 * any function which has blocking code
 */
function name(params, next) {
    setTimeout(() => {
        console.log("name", params)
        params.demo = 100;
        return next(null, "success")
    }, 3000)
}

/*
 * any function which has blocking code
 */
function checkName(params, next) {
    setTimeout(() => {
        console.log("checkName", params)
        params.myName = "ankit";
        return next(null, "success")
    }, 600)
}

/**
 * @param {*} params 
 * respHandler is function for final response handling (optional)
 */
function respHandler(params){
    if(params.demo == 100){
        console.log("respHandler", params)
        console.log("send response for success")
    }else{
        console.log("send response for failed")
    }
}

/**
 * execute unhell.use with first argument as function input values or can be json input
 */

 let params = {value:10} // supports string, int, json .. all type

unhell.use(params, name, checkName, respHandler)


/**
 * @param {*} params 
 * respHandler is function for final response handling (optional)
 * function(err, success){} - callback function for final output
 */
function respHandlerLast(params, function(err, success){
    if(err) throw new Error(err);
    else console.log(success)
})


unhell.useLast(params, name, checkName, respHandlerLast)
