tcp-port-used
=============
A simple Node.js module to check if a TCP port is currently in use. It returns a
deferred promise from the q library.
## Installation
npm install tcp-port-used
## Examples
To check a port's state:
var tcpPortUsed = require('tcp-port-used');
tcpPortUsed.check(44201, '127.0.0.1')
.then(function(inUse) {
console.log('Port 44201 usage: '+inUse);
}, function(err) {
console.error('Error on check:', err.message);
});
To wait until a port on localhost is available:
tcpPortUsed.waitUntilFree(44203, 500, 4000)
.then(function() {
console.log('Port 44203 is now free.');
}, function(err) {
console.log('Error:', err.message);
});
To wait until a port on a host is available:
tcpPortUsed.waitUntilFreeOnHost(44203, 'some.host.com', 500, 4000)
.then(function() {
console.log('Port 44203 on some.host.com is now free.');
}, function(err) {
console.log('Error:', err.message);
});
To wait until a port on localhost is accepting connections:
tcpPortUsed.waitUntilUsed(44204, 500, 4000)
.then(function() {
console.log('Port 44204 is now in use.');
}, function(err) {
console.log('Error:', err.message);
});
To wait until a port on a host is accepting connections:
tcpPortUsed.waitUntilUsedOnHost(44204, 'some.host.com', 500, 4000)
.then(function() {
console.log('Port 44204 on some.host.com is now in use.');
}, function(err) {
console.log('Error:', err.message);
});
To wait until a port on a host is in specific state:
var inUse = true; // wait until the port is in use
tcpPortUsed.waitForStatus(44204, 'some.host.com', inUse, 500, 4000)
.then(function() {
console.log('Port 44204 on some.host.com is now in use.');
}, function(err) {
console.log('Error:', err.message);
});
## API
### check(port [, host])
Checks if a TCP port is in use by attempting to connect to the port on host.
If no host is specified, the module uses '127.0.0.1' (localhost). When the
promise is resolved, there is a parameter `inUse`, when true means the port is
in use and false means the port is free.
**Parameters:**
* **Number|Object** *port* The port you are curious to see if available. If an
object, must contain all the parameters as properties.
* **String** *host* The host name or IP address of the host. Default, if not defined: '127.0.0.1'
**Returns:**
**Object** A deferred promise from the q module.
### waitUntilFree(port [, retryTimeMs] [, timeOutMs])
Returns a deferred promise and fulfills it only when the localhost socket is
free. Will retry on an interval specified in retryTimeMs until the timeout. If
not defined the retryTime is 200 ms and the timeout is 2000 ms.
**Parameters:**
* **Number|Object** *port* a valid TCP port number. If an object must contain
all the parameters as properties.
* **Number** *[retryTimeMs]* the retry interval in milliseconds - defaultis is 100ms.
* **Number** *[timeOutMs]* the amount of time to wait until port is free. Default 300ms.
**Returns:**
**Object** A deferred promise from the q module.
### waitUntilFreeOnHost(port [, host] [, retryTimeMs] [, timeOutMs])
Returns a deferred promise and fulfills it only when the localhost socket is
free. Will retry on an interval specified in retryTimeMs until the timeout. If
not defined the retryTime is 200 ms and the timeout is 2000 ms. If the host is
not defined, the modules uses the default '127.0.0.1'.
**Parameters:**
* **Number|Object** *port* a valid TCP port number. If an object, must contain
all the parameters as properties.
* **String** *host* The host name or IP address of the host. Default, if not defined: '127.0.0.1'
* **Number** *[retryTimeMs]* the retry interval in milliseconds - defaultis is 100ms.
* **Number** *[timeOutMs]* the amount of time to wait until port is free. Default 300ms.
**Returns:**
**Object** A deferred promise from the q module.
### waitUntilUsed(port [, retryTimeMs] [, timeOutMs])
Returns a deferred promise and fulfills it only when the socket is accepting
connections. Will retry on an interval specified in retryTimeMs until the
timeout. If the host is not defined the retryTime is 200 ms and the timeout is
2000 ms.
**Parameters:**
* **Number|Object** *port* a valid TCP port number. If an object, must contain
all the parameters as properties.
* **Number** *[retryTimeMs]* the retry interval in milliseconds - defaultis is 100ms.
* **Number** *[timeOutMs]* the amount of time to wait until port is free. Default 300ms.
**Returns:**
**Object** A deferred promise from the q module.
### waitUntilUsedOnHost(port [, host] [, retryTimeMs] [, timeOutMs])
Returns a deferred promise and fulfills it only when the socket is accepting
connections. Will retry on an interval specified in retryTimeMs until the
timeout. If not defined the retryTime is 200 ms and the timeout is 2000 ms.
If the host is not defined the module uses the default '127.0.0.1'.
**Parameters:**
* **Number|Object** *port* a valid TCP port number. If an object, must contain
all the parameters as properties.
* **String** *host* The host name or IP address of the host. Default, if not defined: '127.0.0.1'
* **Number** *[retryTimeMs]* the retry interval in milliseconds - defaultis is 100ms.
* **Number** *[timeOutMs]* the amount of time to wait until port is free. Default 300ms.
**Returns:**
**Object** A deferred promise from the q module.
### waitForStatus(port, host, status [, retryTimeMs] [, timeOutMs])
Waits until the port on host matches the boolean status in terms of use. If the
status is true, the promise defers until the port is in use. If the status is
false the promise defers until the port is free. If the host is undefined or
null, the module uses the default '127.0.0.1'. Also, if not defined the
retryTime is 200 ms and the timeout is 2000 ms.
**Parameters:**
* **Number** *port* a valid TCP port number. If an object, must contain all the
parameters as properties.
* **String** *host* The host name or IP address of the host. Default, if not defined: '127.0.0.1'
* **Boolean** *status* A boolean describing the condition to wait for in terms of "in use." True indicates wait until the port is in use. False indicates wait until the port is free.
* **Number** *[retryTimeMs]* the retry interval in milliseconds - defaultis is 100ms.
* **Number** *[timeOutMs]* the amount of time to wait until port is free. Default 300ms.
**Returns:**
**Object** A deferred promise from the q module.

A tiny JavaScript debugging utility modelled after Node.js core's debugging
technique. Works in Node.js and web browsers.
## Installation
```bash
$ npm install debug
```
## Usage
`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
Example [_app.js_](./examples/node/app.js):
```js
var debug = require('debug')('http')
, http = require('http')
, name = 'My App';
// fake app
debug('booting %o', name);
http.createServer(function(req, res){
debug(req.method + ' ' + req.url);
res.end('hello\n');
}).listen(3000, function(){
debug('listening');
});
// fake worker of some kind
require('./worker');
```
Example [_worker.js_](./examples/node/worker.js):
```js
var a = require('debug')('worker:a')
, b = require('debug')('worker:b');
function work() {
a('doing lots of uninteresting work');
setTimeout(work, Math.random() * 1000);
}
work();
function workb() {
b('doing some work');
setTimeout(workb, Math.random() * 2000);
}
workb();
```
The `DEBUG` environment variable is then used to enable these based on space or
comma-delimited names.
Here are some examples:

#### Windows command prompt notes
##### CMD
On Windows the environment variable is set using the `set` command.
```cmd
set DEBUG=*,-not_this
```
Example:
```cmd
set DEBUG=* & node app.js
```
##### PowerShell (VS Code default)
PowerShell uses different syntax to set environment variables.
```cmd
$env:DEBUG = "*,-not_this"
```
Example:
```cmd
$env:DEBUG='app';node app.js
```
Then, run the program to be debugged as usual.
npm script example:
```js
"windowsDebug": "@powershell -Command $env:DEBUG='*';node app.js",
```
## Namespace Colors
Every debug instance has a color generated for it based on its namespace name.
This helps when visually parsing the debug output to identify which debug instance
a debug line belongs to.
#### Node.js
In Node.js, colors are enabled when stderr is a TTY. You also _should_ install
the [`supports-color`](https://npmjs.org/supports-color) module alongside debug,
otherwise debug will only use a small handful of basic colors.
<img width="521" src="https://user-images.githubusercontent.com/71256/29092181-47f6a9e6-7c3a-11e7-9a14-1928d8a711cd.png">
#### Web Browser
Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
option. These are WebKit web inspectors, Firefox ([since version
31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
and the Firebug plugin for Firefox (any version).
<img width="524" src="https://user-images.githubusercontent.com/71256/29092033-b65f9f2e-7c39-11e7-8e32-f6f0d8e865c1.png">
## Millisecond diff
When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below:
<img width="647" src="https://user-images.githubusercontent.com/71256/29091956-6bd78372-7c39-11e7-8c55-c948396d6edd.png">
## Conventions
If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output.
## Wildcards
The `*` character may be used as a wildcard. Suppose for example your library has
debuggers named "connect:bodyParser", "connect:compress", "connect:session",
instead of listing all three with
`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do
`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
You can also exclude specific debuggers by prefixing them with a "-" character.
For example, `DEBUG=*,-connect:*` would include all debuggers except those
starting with "connect:".
## Environment Variables
When running through Node.js, you can set a few environment variables that will
change the behavior of the debug logging:
| Name | Purpose |
|-----------|-------------------------------------------------|
| `DEBUG` | Enables/disables specific debugging namespaces. |
| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY). |
| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
| `DEBUG_DEPTH` | Object inspection depth. |
| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
__Note:__ The environment variables beginning with `DEBUG_` end up being
converted into an Options object that gets used with `%o`/`%O` formatters.
See the Node.js documentation for
[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
for the complete list.
## Formatters
Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting.
Below are the officially supported formatters:
| Formatter | Representation |
|-----------|----------------|
| `%O` | Pretty-print an Object on multiple lines. |
| `%o` | Pretty-print an Object all on a single line. |
| `%s` | String. |
| `%d` | Number (both integer and float). |
| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
| `%%` | Single percent sign ('%'). This does not consume an argument. |
### Custom formatters
You can add custom formatters by extending the `debug.formatters` object.
For example, if you wanted to add support for rendering a Buffer as hex with
`%h`, you could do something like:
```js
const createDebug = require('debug')
createDebug.formatters.h = (v) => {
return v.toString('hex')
}
// …elsewhere
const debug = createDebug('foo')
debug('this is hex: %h', new Buffer('hello world'))
// foo this is hex: 68656c6c6f20776f726c6421 +0ms
```
## Browser Support
You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
if you don't want to build it yourself.
Debug's enable state is currently persisted by `localStorage`.
Consider the situation shown below where you have `worker:a` and `worker:b`,
and wish to debug both. You can enable this using `localStorage.debug`:
```js
localStorage.debug = 'worker:*'
```
And then refresh the page.
```js
a = debug('worker:a');
b = debug('worker:b');
setInterval(function(){
a('doing some work');
}, 1000);
setInterval(function(){
b('doing some work');
}, 1200);
```
## Output streams
By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
Example [_stdout.js_](./examples/node/stdout.js):
```js
var debug = require('debug');
var error = debug('app:error');
// by default stderr is used
error('goes to stderr!');
var log = debug('app:log');
// set this namespace to log via console.log
log.log = console.log.bind(console); // don't forget to bind to console!
log('goes to stdout');
error('still goes to stderr!');
// set all output to go via console.info
// overrides all per-namespace log settings
debug.log = console.info.bind(console);
error('now goes to stdout via console.info');
log('still goes to stdout, but via console.info now');
```
## Extend
You can simply extend debugger
```js
const log = require('debug')('auth');
//creates new debug instance with extended namespace
const logSign = log.extend('sign');
const logLogin = log.extend('login');
log('hello'); // auth hello
logSign('hello'); //auth:sign hello
logLogin('hello'); //auth:login hello
```
## Set dynamically
You can also enable debug dynamically by calling the `enable()` method :
```js
let debug = require('debug');
console.log(1, debug.enabled('test'));
debug.enable('test');
console.log(2, debug.enabled('test'));
debug.disable();
console.log(3, debug.enabled('test'));
```
print :
```
1 false
2 true
3 false
```
Usage :
`enable(namespaces)`
`namespaces` can include modes separated by a colon and wildcards.
Note that calling `enable()` completely overrides previously set DEBUG variable :
```
$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))'
=> false
```
`disable()`
Will disable all namespaces. The functions returns the namespaces currently
enabled (and skipped). This can be useful if you want to disable debugging
temporarily without knowing what was enabled to begin with.
For example:
```js
let debug = require('debug');
debug.enable('foo:*,-foo:bar');
let namespaces = debug.disable();
debug.enable(namespaces);
```
Note: There is no guarantee that the string will be identical to the initial
enable string, but semantically they will be identical.
## Checking whether a debug target is enabled
After you've created a debug instance, you can determine whether or not it is
enabled by checking the `enabled` property:
```javascript
const debug = require('debug')('http');
if (debug.enabled) {
// do stuff...
}
```
You can also manually toggle this property to force the debug instance to be
enabled or disabled.
