		||||
 | 
			
		||||
> Promisify a callback-style function
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
## Install
 | 
			
		||||
 | 
			
		||||
```
 | 
			
		||||
$ npm install --save pify
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
## Usage
 | 
			
		||||
 | 
			
		||||
```js
 | 
			
		||||
const fs = require('fs');
 | 
			
		||||
const pify = require('pify');
 | 
			
		||||
 | 
			
		||||
// promisify a single function
 | 
			
		||||
 | 
			
		||||
pify(fs.readFile)('package.json', 'utf8').then(data => {
 | 
			
		||||
	console.log(JSON.parse(data).name);
 | 
			
		||||
	//=> 'pify'
 | 
			
		||||
});
 | 
			
		||||
 | 
			
		||||
// or promisify all methods in a module
 | 
			
		||||
 | 
			
		||||
pify(fs).readFile('package.json', 'utf8').then(data => {
 | 
			
		||||
	console.log(JSON.parse(data).name);
 | 
			
		||||
	//=> 'pify'
 | 
			
		||||
});
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
## API
 | 
			
		||||
 | 
			
		||||
### pify(input, [promiseModule], [options])
 | 
			
		||||
 | 
			
		||||
Returns a promise wrapped version of the supplied function or module.
 | 
			
		||||
 | 
			
		||||
#### input
 | 
			
		||||
 | 
			
		||||
Type: `function`, `object`
 | 
			
		||||
 | 
			
		||||
Callback-style function or module whose methods you want to promisify.
 | 
			
		||||
 | 
			
		||||
#### promiseModule
 | 
			
		||||
 | 
			
		||||
Type: `function`
 | 
			
		||||
 | 
			
		||||
Custom promise module to use instead of the native one.
 | 
			
		||||
 | 
			
		||||
Check out [`pinkie-promise`](https://github.com/floatdrop/pinkie-promise) if you need a tiny promise polyfill.
 | 
			
		||||
 | 
			
		||||
#### options
 | 
			
		||||
 | 
			
		||||
##### multiArgs
 | 
			
		||||
 | 
			
		||||
Type: `boolean`  
 | 
			
		||||
Default: `false`
 | 
			
		||||
 | 
			
		||||
By default, the promisified function will only return the second argument from the callback, which works fine for most APIs. This option can be useful for modules like `request` that return multiple arguments. Turning this on will make it return an array of all arguments from the callback, excluding the error argument, instead of just the second argument.
 | 
			
		||||
 | 
			
		||||
```js
 | 
			
		||||
const request = require('request');
 | 
			
		||||
const pify = require('pify');
 | 
			
		||||
 | 
			
		||||
pify(request, {multiArgs: true})('https://sindresorhus.com').then(result => {
 | 
			
		||||
	const [httpResponse, body] = result;
 | 
			
		||||
});
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
##### include
 | 
			
		||||
 | 
			
		||||
Type: `array` of (`string`|`regex`)
 | 
			
		||||
 | 
			
		||||
Methods in a module to promisify. Remaining methods will be left untouched.
 | 
			
		||||
 | 
			
		||||
##### exclude
 | 
			
		||||
 | 
			
		||||
Type: `array` of (`string`|`regex`)  
 | 
			
		||||
Default: `[/.+Sync$/]`
 | 
			
		||||
 | 
			
		||||
Methods in a module **not** to promisify. Methods with names ending with `'Sync'` are excluded by default.
 | 
			
		||||
 | 
			
		||||
##### excludeMain
 | 
			
		||||
 | 
			
		||||
Type: `boolean`  
 | 
			
		||||
Default: `false`
 | 
			
		||||
 | 
			
		||||
By default, if given module is a function itself, this function will be promisified. Turn this option on if you want to promisify only methods of the module.
 | 
			
		||||
 | 
			
		||||
```js
 | 
			
		||||
const pify = require('pify');
 | 
			
		||||
 | 
			
		||||
function fn() {
 | 
			
		||||
	return true;
 | 
			
		||||
}
 | 
			
		||||
 | 
			
		||||
fn.method = (data, callback) => {
 | 
			
		||||
	setImmediate(() => {
 | 
			
		||||
		callback(data, null);
 | 
			
		||||
	});
 | 
			
		||||
};
 | 
			
		||||
 | 
			
		||||
// promisify methods but not fn()
 | 
			
		||||
const promiseFn = pify(fn, {excludeMain: true});
 | 
			
		||||
 | 
			
		||||
if (promiseFn()) {
 | 
			
		||||
	promiseFn.method('hi').then(data => {
 | 
			
		||||
		console.log(data);
 | 
			
		||||
	});
 | 
			
		||||
}
 | 
			
		||||
```
