+```
+
+## API
+
+The encoder and decoder conforms to [RFC 6763](https://tools.ietf.org/html/rfc6763).
+
+### Initialize
+
+The module exposes a constructor function which can be called with an
+optional options object:
+
+```js
+var txt = require('dns-txt')({ binary: true })
+```
+
+The options are:
+
+- `binary` - If set to `true` all values will be returned as `Buffer`
+ objects. The default behavior is to turn all values into strings. But
+ according to the RFC the values can be any binary data. If you expect
+ binary data, use this option.
+
+#### `txt.encode(obj, [buffer], [offset])`
+
+Takes a key/value object and returns a buffer with the encoded TXT
+record. If a buffer is passed as the second argument the object should
+be encoded into that buffer. Otherwise a new buffer should be allocated
+If an offset is passed as the third argument the object should be
+encoded at that byte offset. The byte offset defaults to `0`.
+
+This module does not actively validate the key/value pairs, but keep the
+following in rules in mind:
+
+- To be RFC compliant, each key should conform with the rules as
+ specified in [section
+ 6.4](https://tools.ietf.org/html/rfc6763#section-6.4).
+
+- To be RFC compliant, each value should conform with the rules as
+ specified in [section
+ 6.5](https://tools.ietf.org/html/rfc6763#section-6.5).
+
+After encoding `txt.encode.bytes` is set to the amount of bytes used to
+encode the object.
+
+#### `txt.decode(buffer, [offset], [length])`
+
+Takes a buffer and returns a decoded key/value object. If an offset is
+passed as the second argument the object should be decoded from that
+byte offset. The byte offset defaults to `0`. Note that all keys will be
+lowercased and all values will be Buffer objects.
+
+After decoding `txt.decode.bytes` is set to the amount of bytes used to
+decode the object.
+
+#### `txt.encodingLength(obj)`
+
+Takes a single key/value object and returns the number of bytes that the given
+object would require if encoded.

+Get the first event in a set of event emitters and event pairs,
+then clean up after itself.
+
+## Install
+
+```sh
+$ npm install ee-first
+```
+
+## API
+
+```js
+var first = require('ee-first')
+```
+
+### first(arr, listener)
+
+Invoke `listener` on the first event from the list specified in `arr`. `arr` is
+an array of arrays, with each array in the format `[ee, ...event]`. `listener`
+will be called only once, the first time any of the given events are emitted. If
+`error` is one of the listened events, then if that fires first, the `listener`
+will be given the `err` argument.
+
+The `listener` is invoked as `listener(err, ee, event, args)`, where `err` is the
+first argument emitted from an `error` event, if applicable; `ee` is the event
+emitter that fired; `event` is the string event name that fired; and `args` is an
+array of the arguments that were emitted on the event.
+
+```js
+var ee1 = new EventEmitter()
+var ee2 = new EventEmitter()
+
+first([
+ [ee1, 'close', 'end', 'error'],
+ [ee2, 'error']
+], function (err, ee, event, args) {
+ // listener invoked
+})
+```
+
+#### .cancel()
+
+The group of listeners can be cancelled before being invoked and have all the event
+listeners removed from the underlying event emitters.
+
+```js
+var thunk = first([
+ [ee1, 'close', 'end', 'error'],
+ [ee2, 'error']
+], function (err, ee, event, args) {
+ // listener invoked
+})
+
+// cancel and clean up
+thunk.cancel()

+
+Encode a URL to a percent-encoded form, excluding already-encoded sequences
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install encodeurl
+```
+
+## API
+
+```js
+var encodeUrl = require('encodeurl')
+```
+
+### encodeUrl(url)
+
+Encode a URL to a percent-encoded form, excluding already-encoded sequences.
+
+This function will take an already-encoded URL and encode all the non-URL
+code points (as UTF-8 byte sequences). This function will not encode the
+"%" character unless it is not part of a valid sequence (`%20` will be
+left as-is, but `%foo` will be encoded as `%25foo`).
+
+This encode is meant to be "safe" and does not throw errors. It will try as
+hard as it can to properly encode the given URL, including replacing any raw,
+unpaired surrogate pairs with the Unicode replacement character prior to
+encoding.
+
+This function is _similar_ to the intrinsic function `encodeURI`, except it
+will not encode the `%` character if that is part of a valid sequence, will
+not encode `[` and `]` (for IPv6 hostnames) and will replace raw, unpaired
+surrogate pairs with the Unicode replacement character (instead of throwing).
+
+## Examples
+
+### Encode a URL containing user-controled data
+
+```js
+var encodeUrl = require('encodeurl')
+var escapeHtml = require('escape-html')
+
+http.createServer(function onRequest (req, res) {
+ // get encoded form of inbound url
+ var url = encodeUrl(req.url)
+
+ // create html message
+ var body = 'Location ' + escapeHtml(url) + ' not found
'
+
+ // send a 404
+ res.statusCode = 404
+ res.setHeader('Content-Type', 'text/html; charset=UTF-8')
+ res.setHeader('Content-Length', String(Buffer.byteLength(body, 'utf-8')))
+ res.end(body, 'utf-8')
+})
+```
+
+### Encode a URL for use in a header field
+
+```js
+var encodeUrl = require('encodeurl')
+var escapeHtml = require('escape-html')
+var url = require('url')
+
+http.createServer(function onRequest (req, res) {
+ // parse inbound url
+ var href = url.parse(req)
+
+ // set new host for redirect
+ href.host = 'localhost'
+ href.protocol = 'https:'
+ href.slashes = true
+
+ // create location header
+ var location = encodeUrl(url.format(href))
+
+ // create html message
+ var body = 'Redirecting to new site: ' + escapeHtml(location) + '
'
+
+ // send a 301
+ res.statusCode = 301
+ res.setHeader('Content-Type', 'text/html; charset=UTF-8')
+ res.setHeader('Content-Length', String(Buffer.byteLength(body, 'utf-8')))
+ res.setHeader('Location', location)
+ res.end(body, 'utf-8')
+})
+```
+

+$ npm test
+$ npm run lint
+```

+$ npm install etag
+```
+
+## API
+
+
+
+```js
+var etag = require('etag')
+```
+
+### etag(entity, [options])
+
+Generate a strong ETag for the given entity. This should be the complete
+body of the entity. Strings, `Buffer`s, and `fs.Stats` are accepted. By
+default, a strong ETag is generated except for `fs.Stats`, which will
+generate a weak ETag (this can be overwritten by `options.weak`).
+
+
+
+```js
+res.setHeader('ETag', etag(body))
+```
+
+#### Options
+
+`etag` accepts these properties in the options object.
+
+##### weak
+
+Specifies if the generated ETag will include the weak validator mark (that
+is, the leading `W/`). The actual entity tag is the same. The default value
+is `false`, unless the `entity` is `fs.Stats`, in which case it is `true`.
+

+# EventEmitter3
+
+[](https://www.npmjs.com/package/eventemitter3)[](https://travis-ci.org/primus/eventemitter3)[](https://david-dm.org/primus/eventemitter3)[](https://coveralls.io/r/primus/eventemitter3?branch=master)[](https://webchat.freenode.net/?channels=primus)

+
+EventEmitter3 is a high performance EventEmitter. It has been micro-optimized
+for various of code paths making this, one of, if not the fastest EventEmitter
+available for Node.js and browsers. The module is API compatible with the
+EventEmitter that ships by default with Node.js but there are some slight
+differences:
+
+- Domain support has been removed.
+- We do not `throw` an error when you emit an `error` event and nobody is
+ listening.
+- The `newListener` and `removeListener` events have been removed as they
+ are useful only in some uncommon use-cases.
+- The `setMaxListeners`, `getMaxListeners`, `prependListener` and
+ `preperndOnceListener` methods are not available.
+- Support for custom context for events so there is no need to use `fn.bind`.
+- The `removeListener` method removes all matching listeners, not only the
+ first.
+
+It's a drop in replacement for existing EventEmitters, but just faster. Free
+performance, who wouldn't want that? The EventEmitter is written in EcmaScript 3
+so it will work in the oldest browsers and node versions that you need to
+support.
+
+## Installation
+
+```bash
+$ npm install --save eventemitter3
+```
+
+## CDN
+
+Recommended CDN:
+
+```text
+https://unpkg.com/eventemitter3@latest/umd/eventemitter3.min.js
+```
+
+## Usage
+
+After installation the only thing you need to do is require the module:
+
+```js
+var EventEmitter = require('eventemitter3');
+```
+
+And you're ready to create your own EventEmitter instances. For the API
+documentation, please follow the official Node.js documentation:
+
+http://nodejs.org/api/events.html
+
+### Contextual emits
+
+We've upgraded the API of the `EventEmitter.on`, `EventEmitter.once` and
+`EventEmitter.removeListener` to accept an extra argument which is the `context`
+or `this` value that should be set for the emitted events. This means you no
+longer have the overhead of an event that required `fn.bind` in order to get a
+custom `this` value.
+
+```js
+var EE = new EventEmitter()
+ , context = { foo: 'bar' };
+
+function emitted() {
+ console.log(this === context); // true
+}
+
+EE.once('event-name', emitted, context);
+EE.on('another-event', emitted, context);
+EE.removeListener('another-event', emitted, context);
+```
+
+### Tests and benchmarks
+
+This module is well tested. You can run:
+
+- `npm test` to run the tests under Node.js.
+- `npm run test-browser` to run the tests in real browsers via Sauce Labs.
+
+We also have a set of benchmarks to compare EventEmitter3 with some available
+alternatives. To run the benchmarks run `npm run benchmark`.
+
+Tests and benchmarks are not included in the npm package. If you want to play
+with them you have to clone the GitHub repository.

+```
+
+Now you will have two global constructors:
+
+```javascript
+window.EventSourcePolyfill
+window.EventSource // Unchanged if browser has defined it. Otherwise, same as window.EventSourcePolyfill
+```
+
+If you're using [webpack](https://webpack.github.io/) or [browserify](http://browserify.org/)
+you can of course build your own. (The `example/eventsource-polyfill.js` is built with webpack).
+
+## Extensions to the W3C API
+
+### Setting HTTP request headers
+
+You can define custom HTTP headers for the initial HTTP request. This can be useful for e.g. sending cookies
+or to specify an initial `Last-Event-ID` value.
+
+HTTP headers are defined by assigning a `headers` attribute to the optional `eventSourceInitDict` argument:
+
+```javascript
+var eventSourceInitDict = {headers: {'Cookie': 'test=test'}};
+var es = new EventSource(url, eventSourceInitDict);
+```
+
+### Allow unauthorized HTTPS requests
+
+By default, https requests that cannot be authorized will cause the connection to fail and an exception
+to be emitted. You can override this behaviour, along with other https options:
+
+```javascript
+var eventSourceInitDict = {https: {rejectUnauthorized: false}};
+var es = new EventSource(url, eventSourceInitDict);
+```
+
+Note that for Node.js < v0.10.x this option has no effect - unauthorized HTTPS requests are *always* allowed.
+
+### HTTP status code on error events
+
+Unauthorized and redirect error status codes (for example 401, 403, 301, 307) are available in the `status` property in the error event.
+
+```javascript
+es.onerror = function (err) {
+ if (err) {
+ if (err.status === 401 || err.status === 403) {
+ console.log('not authorized');
+ }
+ }
+};
+```
+
+### HTTP/HTTPS proxy
+
+You can define a `proxy` option for the HTTP request to be used. This is typically useful if you are behind a corporate firewall.
+
+```javascript
+var es = new EventSource(url, {proxy: 'http://your.proxy.com'});
+```

+
+// a transform stream is a readable/writable stream where you do
+// something with the data. Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored. (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation. For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes. When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up. When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer. When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks. If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk. However,
+// a pathological inflate type of transform can cause excessive buffering
+// here. For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output. In this case, you could write a very small
+// amount of input, and end up with a very large amount of output. In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform. A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.
