# SPDY Server for node.js
[![Build Status](https://travis-ci.org/spdy-http2/node-spdy.svg?branch=master)](http://travis-ci.org/spdy-http2/node-spdy)

[![Waffle](https://img.shields.io/badge/track-waffle-blue.svg?style=flat-square)](https://waffle.io/spdy-http2/node-spdy)
With this module you can create [HTTP2][0] / [SPDY][1] servers
in node.js with natural http module interface and fallback to regular https
(for browsers that don't support neither HTTP2, nor SPDY yet).
This module named `spdy` but it [provides](https://github.com/indutny/node-spdy/issues/269#issuecomment-239014184) support for both http/2 (h2) and spdy (2,3,3.1). Also, `spdy` is compatible with Express.
## Usage
### Examples
Server:
```javascript
var spdy = require('spdy'),
fs = require('fs');
var options = {
// Private key
key: fs.readFileSync(__dirname + '/keys/spdy-key.pem'),
// Fullchain file or cert file (prefer the former)
cert: fs.readFileSync(__dirname + '/keys/spdy-fullchain.pem'),
// **optional** SPDY-specific options
spdy: {
protocols: [ 'h2', 'spdy/3.1', ..., 'http/1.1' ],
plain: false,
// **optional**
// Parse first incoming X_FORWARDED_FOR frame and put it to the
// headers of every request.
// NOTE: Use with care! This should not be used without some proxy that
// will *always* send X_FORWARDED_FOR
'x-forwarded-for': true,
connection: {
windowSize: 1024 * 1024, // Server's window size
// **optional** if true - server will send 3.1 frames on 3.0 *plain* spdy
autoSpdy31: false
}
}
};
var server = spdy.createServer(options, function(req, res) {
res.writeHead(200);
res.end('hello world!');
});
server.listen(3000);
```
Client:
```javascript
var spdy = require('spdy');
var https = require('https');
var agent = spdy.createAgent({
host: 'www.google.com',
port: 443,
// Optional SPDY options
spdy: {
plain: false,
ssl: true,
// **optional** send X_FORWARDED_FOR
'x-forwarded-for': '127.0.0.1'
}
});
https.get({
host: 'www.google.com',
agent: agent
}, function(response) {
console.log('yikes');
// Here it goes like with any other node.js HTTP request
// ...
// And once we're done - we may close TCP connection to server
// NOTE: All non-closed requests will die!
agent.close();
}).end();
```
Please note that if you use a custom agent, by default all connection-level
errors will result in an uncaught exception. To handle these errors subscribe
to the `error` event and re-emit the captured error:
```javascript
var agent = spdy.createAgent({
host: 'www.google.com',
port: 443
}).once('error', function (err) {
this.emit(err);
});
```
#### Push streams
It is possible to initiate [PUSH_PROMISE][5] to send content to clients _before_
the client requests it.
```javascript
spdy.createServer(options, function(req, res) {
var stream = res.push('/main.js', {
status: 200, // optional
method: 'GET', // optional
request: {
accept: '*/*'
},
response: {
'content-type': 'application/javascript'
}
});
stream.on('error', function() {
});
stream.end('alert("hello from push stream!");');
res.end('<script src="/main.js"></script>');
}).listen(3000);
```
[PUSH_PROMISE][5] may be sent using the `push()` method on the current response
object. The signature of the `push()` method is:
`.push('/some/relative/url', { request: {...}, response: {...} }, callback)`
Second argument contains headers for both PUSH_PROMISE and emulated response.
`callback` will receive two arguments: `err` (if any error is happened) and a
[Duplex][4] stream as the second argument.
Client usage:
```javascript
var agent = spdy.createAgent({ /* ... */ });
var req = http.get({
host: 'www.google.com',
agent: agent
}, function(response) {
});
req.on('push', function(stream) {
stream.on('error', function(err) {
// Handle error
});
// Read data from stream
});
```
NOTE: You're responsible for the `stream` object once given it in `.push()`
callback or `push` event. Hence ignoring `error` event on it will result in
uncaught exception and crash your program.
#### Trailing headers
Server usage:
```javascript
function (req, res) {
// Send trailing headers to client
res.addTrailers({ header1: 'value1', header2: 'value2' });
// On client's trailing headers
req.on('trailers', function(headers) {
// ...
});
}
```
Client usage:
```javascript
var req = http.request({ agent: spdyAgent, /* ... */ }).function (res) {
// On server's trailing headers
res.on('trailers', function(headers) {
// ...
});
});
req.write('stuff');
req.addTrailers({ /* ... */ });
req.end();
```
#### Options
All options supported by [tls][2] work with node-spdy.
Additional options may be passed via `spdy` sub-object:
* `plain` - if defined, server will ignore NPN and ALPN data and choose whether
to use spdy or plain http by looking at first data packet.
* `ssl` - if `false` and `options.plain` is `true`, `http.Server` will be used
as a `base` class for created server.
* `maxChunk` - if set and non-falsy, limits number of bytes sent in one DATA
chunk. Setting it to non-zero value is recommended if you care about
interleaving of outgoing data from multiple different streams.
(defaults to 8192)
* `protocols` - list of NPN/ALPN protocols to use (default is:
`['h2','spdy/3.1', 'spdy/3', 'spdy/2','http/1.1', 'http/1.0']`)
* `protocol` - use specific protocol if no NPN/ALPN ex In addition,
* `maxStreams` - set "[maximum concurrent streams][3]" protocol option
### API
API is compatible with `http` and `https` module, but you can use another
function as base class for SPDYServer.
```javascript
spdy.createServer(
[base class constructor, i.e. https.Server],
{ /* keys and options */ }, // <- the only one required argument
[request listener]
).listen([port], [host], [callback]);
```
Request listener will receive two arguments: `request` and `response`. They're
both instances of `http`'s `IncomingMessage` and `OutgoingMessage`. But three
custom properties are added to both of them: `isSpdy`, `spdyVersion`. `isSpdy`
is `true` when the request was processed using HTTP2/SPDY protocols, it is
`false` in case of HTTP/1.1 fallback. `spdyVersion` is either of: `2`, `3`,
`3.1`, or `4` (for HTTP2).

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.

# ms
[![Build Status](https://travis-ci.org/zeit/ms.svg?branch=master)](https://travis-ci.org/zeit/ms)
[![Join the community on Spectrum](https://withspectrum.github.io/badge/badge.svg)](https://spectrum.chat/zeit)
Use this package to easily convert various time formats to milliseconds.
## Examples
```js
ms('2 days') // 172800000
ms('1d') // 86400000
ms('10h') // 36000000
ms('2.5 hrs') // 9000000
ms('2h') // 7200000
ms('1m') // 60000
ms('5s') // 5000
ms('1y') // 31557600000
ms('100') // 100
ms('-3 days') // -259200000
ms('-1h') // -3600000
ms('-200') // -200
```
### Convert from Milliseconds
```js
ms(60000) // "1m"
ms(2 * 60000) // "2m"
ms(-3 * 60000) // "-3m"
ms(ms('10 hours')) // "10h"
```
### Time Format Written-Out
```js
ms(60000, { long: true }) // "1 minute"
ms(2 * 60000, { long: true }) // "2 minutes"
ms(-3 * 60000, { long: true }) // "-3 minutes"
ms(ms('10 hours'), { long: true }) // "10 hours"
```
## Features
- Works both in [Node.js](https://nodejs.org) and in the browser
- If a number is supplied to `ms`, a string with a unit is returned
- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`)
- If you pass a string with a number and a valid unit, the number of equivalent milliseconds is returned
## Related Packages
- [ms.macro](https://github.com/knpwrs/ms.macro) - Run `ms` as a macro at build-time.
## Caught a Bug?
1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
2. Link the package to the global module directory: `npm link`
3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, Node.js will now use your clone of ms!
As always, you can run the tests using: `npm test`
