## Breaking Changes

# 1.2.0
|
||||
|
||||
Some recent changes in 1.1.0 [[`3b90e2ca74`](https://github.com/baalexander/node-portscanner/commit/3b90e2ca74)] [[`eb345da68c`](https://github.com/baalexander/node-portscanner/commit/eb345da68c)] were based on the assumption that the ports would always be of the type numbers. This broke portscanner in some cases [#49](https://github.com/baalexander/node-portscanner/issues/49) [#50](https://github.com/baalexander/node-portscanner/issues/50). All changes were reverted back to 1.0.0 and only some very critical fixes [[`4c7a88436f`](https://github.com/baalexander/node-portscanner/commit/4c7a88436f)] [[`04fea5dd4d`](https://github.com/baalexander/node-portscanner/commit/04fea5dd4d)] were applied to this version.

# portscanner
|
||||
|
||||
[](https://www.npmjs.com/package/portscanner)
|
||||
[](http://standardjs.com/)
|
||||
|
||||
The portscanner module is
|
||||
an asynchronous JavaScript port scanner for Node.js.
|
||||
|
||||
Portscanner can check a port,
|
||||
or range of ports,
|
||||
for 'open' or 'closed' statuses.
|
||||
|
||||
[Looking for maintainer](https://github.com/baalexander/node-portscanner/issues/25)!
|
||||
|
||||
## Install
|
||||
|
||||
```bash
|
||||
npm install portscanner
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
A brief example:
|
||||
|
||||
```javascript
|
||||
var portscanner = require('portscanner')
|
||||
|
||||
// Checks the status of a single port
|
||||
portscanner.checkPortStatus(3000, '127.0.0.1', function(error, status) {
|
||||
// Status is 'open' if currently in use or 'closed' if available
|
||||
console.log(status)
|
||||
})
|
||||
|
||||
// Find the first available port. Asynchronously checks, so first port
|
||||
// determined as available is returned.
|
||||
portscanner.findAPortNotInUse(3000, 3010, '127.0.0.1', function(error, port) {
|
||||
console.log('AVAILABLE PORT AT: ' + port)
|
||||
})
|
||||
|
||||
// Find the first port in use or blocked. Asynchronously checks, so first port
|
||||
// to respond is returned.
|
||||
portscanner.findAPortInUse(3000, 3010, '127.0.0.1', function(error, port) {
|
||||
console.log('PORT IN USE AT: ' + port)
|
||||
})
|
||||
|
||||
// You can also pass array of ports to check
|
||||
portscanner.findAPortInUse([3000, 3005, 3006], '127.0.0.1', function(error, port) {
|
||||
console.log('PORT IN USE AT: ' + port)
|
||||
})
|
||||
|
||||
// And skip host param. Default is '127.0.0.1'
|
||||
portscanner.findAPortNotInUse(3000, 4000, function(error, port) {
|
||||
console.log('PORT IN USE AT: ' + port)
|
||||
})
|
||||
|
||||
// And use promises
|
||||
portscanner.findAPortNotInUse(3000, 4000).then(function(port) {
|
||||
console.log('PORT IN USE AT: ' + port)
|
||||
})
|
||||
```
|
||||
|
||||
The example directory contains a more detailed example.
|
||||
|
||||
## Test
|
||||
|
||||
```sh
|
||||
npm test
|
||||
```
|
||||
|
||||
## Future
|
||||
|
||||
Please create issues or pull requests
|
||||
for port scanning related features
|
||||
you'd like to see included.
