## Installation

```bash

$ npm install --save promise4solo

```

## Example

```js

var solo = require('promise4solo')();

var now = function () {

  this.start = this.start || Date.now();

  return Date.now() - this.start;

};

var singAsync = function (ms) {

  var self = this;

  var ts = now();

  if (!ms) {

    throw new Error(ts + self.name + ' oops');

  }

  console.log(ts + self.name + ' begin sing ' + ms);

  return new Promise(function (resolve) {

    setTimeout(function () {

      var end = now();

      console.log(end + self.name + ' end sing ' + ms);

      resolve(end);

    }, ms);

  });

};

var who = {

  name: ' joey'

};

var singSolo = solo(singAsync, who);

var saySolo = solo(function (msg) {

  console.log(now() + this.name + ' say ' + msg);

}, who);

singSolo(1000);

saySolo('hi');

singSolo().catch(function (err) {

  console.log(err.message);

});

singSolo(100).then(function (end) {

  console.log(end + ' done');

});

console.log(now() + ' start');

// Output:

// 0 start

// 3 joey begin sing 1000

// 1011 joey end sing 1000

// 1011 joey say hi

// 1011 joey oops

// 1012 joey begin sing 100

// 1118 joey end sing 100

// 1118 done

```

## API

Return a solo wrap function, and the wrap function will return promise and guarantee one async function be run for order async flow.

var funcAsync = function(val){

  return new Promise(function(resolve){

    //...

    resolve(val);

  });

}

var funcSolo = solo(funcAsync);

funcSolo(true).then(function (val) {

});

```
