How to install:

npm install simplesync

How to use:

//First you need to require simplesync modulevar sync = require('simplesync');//Any sync call must be in a sync block.sync.block(function() {//Standard async callSome_Async_Function(123, function(ta) {//ta will be 123.});//We name the first parameter of callback to "ta"//If there is multi parameters in callback function, just using like this://sync.cb("ta1", "ta2", "ta3");//var result = sync.wait(Some_Async_Function(123, sync.cb("ta")));//Now we can use the "ta" in result. This will print 123.//console.log("TA:= " + result.ta);//And you can wait for multi functions finished, like this:result = sync.wait(function() {Some_Async_Function(123, sync.cb("ta"));Some_Async_Function2(123, sync.cb("ta", "ta2"));});////result[0].ta  = 123;//result[1].ta  = 124;//result[1].ta2 = 678;}//Sample async function. It is no matter about this function is in or not in the sync block.function Some_Async_Function(input, callback) {callback(input);}function Some_Async_Function2(input, callback) {callback(input + 1, 678);}

Chinese document: 支持单个函数异步转同步调用，或者一组函数并行运行后转同步调用。

如何使用： //首先引入模块， var sync = require('simplesync');

//任何同步调用都必须位于一个sync.block块内, sync.block描述可以嵌套。sync.block(function() {    //标准异步调用方式    Some_Async_Function(123, function(ta) {        //这里参数ta的值是124    });    //这是同步调用方式, result.ta就是124    var result = sync.wait(Some_Async_Function(123, sync.cb("ta")));    //多个参数就这么办    function Async_Function2(input, callback) {        callback(input, 456);    }    //这里result.ta就是123, result.ta2就是456了    result = sync.wait(Async_Function2(123, sync.cb("ta", "ta2")));//当需要等待多个函数并行运行后统一结束的，用如下的方式：result = sync.wait(function() {Some_Async_Function(123, sync.cb("ta"));Some_Async_Function2(123, sync.cb("ta", "ta2"));});////result[0].ta  = 123;//result[1].ta  = 124;//result[1].ta2 = 678;    }//异步调用函数可以在sync.block内，也可以不在，无所谓。function Some_Async_Function(input, callback) {            callback(input+1);}function Some_Async_Function2(input, callback) {callback(input + 1, 678);}
