+# axios-error
+
+> An axios error wrapper that aim to provide clear error message to the user
+
+## Installation
+
+```sh
+npm i --save axios-error
+```
+
+or
+
+```sh
+yarn add axios-error
+```
+
+<br />
+
+## Usage
+
+```js
+const AxiosError = require('axios-error');
+
+// You can construct it from error throw by axios
+const error = new AxiosError(errorThrowByAxios);
+
+// Or with custom error message
+const error = new AxiosError(message, errorThrowByAxios);
+
+// Or construct it from axios config, axios request and axios response
+const error = new AxiosError(message, { config, request, response });
+```
+
+Directly `console.log` on the error instance will return formatted message. If you'd like to get the axios `request`, `response`, or `config`, you can still get them via those keys on the error instance.
+
+```js
+console.log(error); // formatted error message
+console.log(error.stack); // error stack trace
+console.log(error.config); // axios request config
+console.log(error.request); // HTTP request
+console.log(error.response); // HTTP response
+```

+# file-type [![Build Status](https://travis-ci.org/sindresorhus/file-type.svg?branch=master)](https://travis-ci.org/sindresorhus/file-type)
+
+> Detect the file type of a Buffer/Uint8Array/ArrayBuffer
+
+The file type is detected by checking the [magic number](https://en.wikipedia.org/wiki/Magic_number_(programming)#Magic_numbers_in_files) of the buffer.
+
+
+## Install
+
+```
+$ npm install file-type
+```

+
+
+## Usage
+
+##### Node.js
+
+```js
+const readChunk = require('read-chunk');
+const fileType = require('file-type');
+
+const buffer = readChunk.sync('unicorn.png', 0, fileType.minimumBytes);
+
+fileType(buffer);
+//=> {ext: 'png', mime: 'image/png'}
+```
+
+Or from a remote location:
+
+```js
+const http = require('http');
+const fileType = require('file-type');
+
+const url = 'https://assets-cdn.github.com/images/spinners/octocat-spinner-32.gif';
+
+http.get(url, response => {
+	response.on('readable', () => {
+		const chunk = response.read(fileType.minimumBytes);
+		response.destroy();
+		console.log(fileType(chunk));
+		//=> {ext: 'gif', mime: 'image/gif'}
+	});
+});
+```
+
+Or from a stream:
+
+```js
+const fs = require('fs');
+const crypto = require('crypto');
+const fileType = require('file-type');
+
+(async () => {
+	const read = fs.createReadStream('encrypted.enc');
+	const decipher = crypto.createDecipheriv(alg, key, iv);
+
+	const stream = await fileType.stream(read.pipe(decipher));
+
+	console.log(stream.fileType);
+	//=> {ext: 'mov', mime: 'video/quicktime'}
+
+	const write = fs.createWriteStream(`decrypted.${stream.fileType.ext}`);
+	stream.pipe(write);
+})();
+```
+
+
+##### Browser
+
+```js
+const xhr = new XMLHttpRequest();
+xhr.open('GET', 'unicorn.png');
+xhr.responseType = 'arraybuffer';
+
+xhr.onload = () => {
+	fileType(new Uint8Array(this.response));
+	//=> {ext: 'png', mime: 'image/png'}
+};
+
+xhr.send();
+```
+
+
+## API
+
+### fileType(input)
+
+Returns an `Object` with:
+
+- `ext` - One of the [supported file types](#supported-file-types)
+- `mime` - The [MIME type](https://en.wikipedia.org/wiki/Internet_media_type)
+
+Or `null` when there is no match.
+
+#### input
+
+Type: `Buffer | Uint8Array | ArrayBuffer`
+
+It only needs the first `.minimumBytes` bytes. The exception is detection of `docx`, `pptx`, and `xlsx` which potentially requires reading the whole file.
+
+### fileType.minimumBytes
+
+Type: `number`
+
+The minimum amount of bytes needed to detect a file type. Currently, it's 4100 bytes, but it can change, so don't hardcode it.
+
+### fileType.stream(readableStream)
+
+Detect the file type of a readable stream.
+
+Returns a `Promise` which resolves to the original readable stream argument, but with an added `fileType` property, which is an object like the one returned from `fileType()`.
+
+*Note:* This method is only for Node.js.
+
+#### readableStream
+
+Type: [`stream.Readable`](https://nodejs.org/api/stream.html#stream_class_stream_readable)

+# invariant
+
+[![Build Status](https://travis-ci.org/zertosh/invariant.svg?branch=master)](https://travis-ci.org/zertosh/invariant)
+
+A mirror of Facebook's `invariant` (e.g. [React](https://github.com/facebook/react/blob/v0.13.3/src/vendor/core/invariant.js), [flux](https://github.com/facebook/flux/blob/2.0.2/src/invariant.js)).
+
+A way to provide descriptive errors in development but generic errors in production.
+
+## Install
+
+With [npm](http://npmjs.org) do:
+
+```sh
+npm install invariant
+```
+
+## `invariant(condition, message)`
+
+```js
+var invariant = require('invariant');
+
+invariant(someTruthyVal, 'This will not throw');
+// No errors
+
+invariant(someFalseyVal, 'This will throw an error with this message');
+// Error: Invariant Violation: This will throw an error with this message
+```
+
+**Note:** When `process.env.NODE_ENV` is not `production`, the message is required. If omitted, `invariant` will throw regardless of the truthiness of the condition. When `process.env.NODE_ENV` is `production`, the message is optional – so they can be minified away.
+
+### Browser
+
+When used with [browserify](https://github.com/substack/node-browserify), it'll use `browser.js` (instead of `invariant.js`) and the [envify](https://github.com/hughsk/envify) transform will inline the value of `process.env.NODE_ENV`.
+
+### Node
+
+The node version is optimized around the performance implications of accessing `process.env`. The value of `process.env.NODE_ENV` is cached, and repeatedly used instead of reading `process.env`. See [Server rendering is slower with npm react #812](https://github.com/facebook/react/issues/812)

+### Version 4.0.0 (2018-01-28) ###
+
+- Added: Support for ES2018. The only change needed was recognizing the `s`
+  regex flag.
+- Changed: _All_ tokens returned by the `matchToToken` function now have a
+  `closed` property. It is set to `undefined` for the tokens where “closed”
+  doesn’t make sense. This means that all tokens objects have the same shape,
+  which might improve performance.
+
+These are the breaking changes:
+
+- `'/a/s'.match(jsTokens)` no longer returns `['/', 'a', '/', 's']`, but
+  `['/a/s']`. (There are of course other variations of this.)
+- Code that rely on some token objects not having the `closed` property could
+  now behave differently.
+
+
+### Version 3.0.2 (2017-06-28) ###
+
+- No code changes. Just updates to the readme.
+
+
+### Version 3.0.1 (2017-01-30) ###
+
+- Fixed: ES2015 unicode escapes with more than 6 hex digits are now matched
+  correctly.
+
+
+### Version 3.0.0 (2017-01-11) ###
+
+This release contains one breaking change, that should [improve performance in
+V8][v8-perf]:
+
+> So how can you, as a JavaScript developer, ensure that your RegExps are fast?
+> If you are not interested in hooking into RegExp internals, make sure that
+> neither the RegExp instance, nor its prototype is modified in order to get the
+> best performance:
+>
+> ```js
+> var re = /./g;
+> re.exec('');  // Fast path.
+> re.new_property = 'slow';
+> ```
+
+This module used to export a single regex, with `.matchToToken` bolted
+on, just like in the above example. This release changes the exports of
+the module to avoid this issue.
+
+Before:
+
+```js
+import jsTokens from "js-tokens"
+// or:
+var jsTokens = require("js-tokens")
+var matchToToken = jsTokens.matchToToken
+```
+
+After:
+
+```js
+import jsTokens, {matchToToken} from "js-tokens"
+// or:
+var jsTokens = require("js-tokens").default
+var matchToToken = require("js-tokens").matchToToken
+```
+
+[v8-perf]: http://v8project.blogspot.se/2017/01/speeding-up-v8-regular-expressions.html
+
+
+### Version 2.0.0 (2016-06-19) ###
+
+- Added: Support for ES2016. In other words, support for the `**` exponentiation
+  operator.
+
+These are the breaking changes:
+
+- `'**'.match(jsTokens)` no longer returns `['*', '*']`, but `['**']`.
+- `'**='.match(jsTokens)` no longer returns `['*', '*=']`, but `['**=']`.
+
+
+### Version 1.0.3 (2016-03-27) ###
+
+- Improved: Made the regex ever so slightly smaller.
+- Updated: The readme.
+
+
+### Version 1.0.2 (2015-10-18) ###
+
+- Improved: Limited npm package contents for a smaller download. Thanks to
+  @zertosh!
+
+
+### Version 1.0.1 (2015-06-20) ###
+
+- Fixed: Declared an undeclared variable.
+
+
+### Version 1.0.0 (2015-02-26) ###
+
+- Changed: Merged the 'operator' and 'punctuation' types into 'punctuator'. That
+  type is now equivalent to the Punctuator token in the ECMAScript
+  specification. (Backwards-incompatible change.)
+- Fixed: A `-` followed by a number is now correctly matched as a punctuator
+  followed by a number. It used to be matched as just a number, but there is no
+  such thing as negative number literals. (Possibly backwards-incompatible
+  change.)
+
+
+### Version 0.4.1 (2015-02-21) ###
+
+- Added: Support for the regex `u` flag.
+
+
+### Version 0.4.0 (2015-02-21) ###
+
+- Improved: `jsTokens.matchToToken` performance.
+- Added: Support for octal and binary number literals.
+- Added: Support for template strings.
+
+
+### Version 0.3.1 (2015-01-06) ###
+
+- Fixed: Support for unicode spaces. They used to be allowed in names (which is
+  very confusing), and some unicode newlines were wrongly allowed in strings and
+  regexes.
+
+
+### Version 0.3.0 (2014-12-19) ###
+
+- Changed: The `jsTokens.names` array has been replaced with the
+  `jsTokens.matchToToken` function. The capturing groups of `jsTokens` are no
+  longer part of the public API; instead use said function. See this [gist] for
+  an example. (Backwards-incompatible change.)
+- Changed: The empty string is now considered an “invalid” token, instead an
+  “empty” token (its own group). (Backwards-incompatible change.)
+- Removed: component support. (Backwards-incompatible change.)
+
+[gist]: https://gist.github.com/lydell/be49dbf80c382c473004
+
+
+### Version 0.2.0 (2014-06-19) ###
+
+- Changed: Match ES6 function arrows (`=>`) as an operator, instead of its own
+  category (“functionArrow”), for simplicity. (Backwards-incompatible change.)
+- Added: ES6 splats (`...`) are now matched as an operator (instead of three
+  punctuations). (Backwards-incompatible change.)
+
+
+### Version 0.1.0 (2014-03-08) ###
+
+- Initial release.

+Overview [![Build Status](https://travis-ci.org/lydell/js-tokens.svg?branch=master)](https://travis-ci.org/lydell/js-tokens)
+========
+
+A regex that tokenizes JavaScript.
+
+```js
+var jsTokens = require("js-tokens").default
+
+var jsString = "var foo=opts.foo;\n..."
+
+jsString.match(jsTokens)
+// ["var", " ", "foo", "=", "opts", ".", "foo", ";", "\n", ...]
+```
+
+
+Installation
+============
+
+`npm install js-tokens`
+
+```js
+import jsTokens from "js-tokens"
+// or:
+var jsTokens = require("js-tokens").default
+```
+
+
+Usage
+=====
+
+### `jsTokens` ###
+
+A regex with the `g` flag that matches JavaScript tokens.
+
+The regex _always_ matches, even invalid JavaScript and the empty string.
+
+The next match is always directly after the previous.
+
+### `var token = matchToToken(match)` ###
+
+```js
+import {matchToToken} from "js-tokens"
+// or:
+var matchToToken = require("js-tokens").matchToToken
+```
+
+Takes a `match` returned by `jsTokens.exec(string)`, and returns a `{type:
+String, value: String}` object. The following types are available:
+
+- string
+- comment
+- regex
+- number
+- name
+- punctuator
+- whitespace
+- invalid
+
+Multi-line comments and strings also have a `closed` property indicating if the
+token was closed or not (see below).
+
+Comments and strings both come in several flavors. To distinguish them, check if
+the token starts with `//`, `/*`, `'`, `"` or `` ` ``.
+
+Names are ECMAScript IdentifierNames, that is, including both identifiers and
+keywords. You may use [is-keyword-js] to tell them apart.
+
+Whitespace includes both line terminators and other whitespace.
+
+[is-keyword-js]: https://github.com/crissdev/is-keyword-js
+
+
+ECMAScript support
+==================
+
+The intention is to always support the latest ECMAScript version whose feature
+set has been finalized.
+
+If adding support for a newer version requires changes, a new version with a
+major verion bump will be released.
+
+Currently, ECMAScript 2018 is supported.
+
+
+Invalid code handling
+=====================
+
+Unterminated strings are still matched as strings. JavaScript strings cannot
+contain (unescaped) newlines, so unterminated strings simply end at the end of
+the line. Unterminated template strings can contain unescaped newlines, though,
+so they go on to the end of input.
+
+Unterminated multi-line comments are also still matched as comments. They
+simply go on to the end of the input.
+
+Unterminated regex literals are likely matched as division and whatever is
+inside the regex.
+
+Invalid ASCII characters have their own capturing group.
+
+Invalid non-ASCII characters are treated as names, to simplify the matching of
+names (except unicode spaces which are treated as whitespace). Note: See also
+the [ES2018](#es2018) section.
+
+Regex literals may contain invalid regex syntax. They are still matched as
+regex literals. They may also contain repeated regex flags, to keep the regex
+simple.
+
+Strings may contain invalid escape sequences.
+
+
+Limitations
+===========
+
+Tokenizing JavaScript using regexes—in fact, _one single regex_—won’t be
+perfect. But that’s not the point either.
+
+You may compare jsTokens with [esprima] by using `esprima-compare.js`.
+See `npm run esprima-compare`!
+
+[esprima]: http://esprima.org/
+
+### Template string interpolation ###
+
+Template strings are matched as single tokens, from the starting `` ` `` to the
+ending `` ` ``, including interpolations (whose tokens are not matched
+individually).
+
+Matching template string interpolations requires recursive balancing of `{` and
+`}`—something that JavaScript regexes cannot do. Only one level of nesting is
+supported.
+
+### Division and regex literals collision ###
+
+Consider this example:
+
+```js
+var g = 9.82
+var number = bar / 2/g
+
+var regex = / 2/g
+```
+
+A human can easily understand that in the `number` line we’re dealing with
+division, and in the `regex` line we’re dealing with a regex literal. How come?
+Because humans can look at the whole code to put the `/` characters in context.
+A JavaScript regex cannot. It only sees forwards. (Well, ES2018 regexes can also
+look backwards. See the [ES2018](#es2018) section).
+
+When the `jsTokens` regex scans throught the above, it will see the following
+at the end of both the `number` and `regex` rows:
+
+```js
+/ 2/g
+```
+
+It is then impossible to know if that is a regex literal, or part of an
+expression dealing with division.
+
+Here is a similar case:
+
+```js
+foo /= 2/g
+foo(/= 2/g)
+```
+
+The first line divides the `foo` variable with `2/g`. The second line calls the
+`foo` function with the regex literal `/= 2/g`. Again, since `jsTokens` only
+sees forwards, it cannot tell the two cases apart.
+
+There are some cases where we _can_ tell division and regex literals apart,
+though.
+
+First off, we have the simple cases where there’s only one slash in the line:
+
+```js
+var foo = 2/g
+foo /= 2
+```
+
+Regex literals cannot contain newlines, so the above cases are correctly
+identified as division. Things are only problematic when there are more than
+one non-comment slash in a single line.
+
+Secondly, not every character is a valid regex flag.
+
+```js
+var number = bar / 2/e
+```
+
+The above example is also correctly identified as division, because `e` is not a
+valid regex flag. I initially wanted to future-proof by allowing `[a-zA-Z]*`
+(any letter) as flags, but it is not worth it since it increases the amount of
+ambigous cases. So only the standard `g`, `m`, `i`, `y` and `u` flags are
+allowed. This means that the above example will be identified as division as
+long as you don’t rename the `e` variable to some permutation of `gmiyus` 1 to 6
+characters long.
+
+Lastly, we can look _forward_ for information.
+
+- If the token following what looks like a regex literal is not valid after a
+  regex literal, but is valid in a division expression, then the regex literal
+  is treated as division instead. For example, a flagless regex cannot be
+  followed by a string, number or name, but all of those three can be the
+  denominator of a division.
+- Generally, if what looks like a regex literal is followed by an operator, the
+  regex literal is treated as division instead. This is because regexes are
+  seldomly used with operators (such as `+`, `*`, `&&` and `==`), but division
+  could likely be part of such an expression.
+
+Please consult the regex source and the test cases for precise information on
+when regex or division is matched (should you need to know). In short, you
+could sum it up as:
+
+If the end of a statement looks like a regex literal (even if it isn’t), it
+will be treated as one. Otherwise it should work as expected (if you write sane
+code).
+
+### ES2018 ###
+
+ES2018 added some nice regex improvements to the language.
+
+- [Unicode property escapes] should allow telling names and invalid non-ASCII
+  characters apart without blowing up the regex size.
+- [Lookbehind assertions] should allow matching telling division and regex
+  literals apart in more cases.
+- [Named capture groups] might simplify some things.
+
+These things would be nice to do, but are not critical. They probably have to
+wait until the oldest maintained Node.js LTS release supports those features.

+# loose-envify
+
+[![Build Status](https://travis-ci.org/zertosh/loose-envify.svg?branch=master)](https://travis-ci.org/zertosh/loose-envify)
+
+Fast (and loose) selective `process.env` replacer using [js-tokens](https://github.com/lydell/js-tokens) instead of an AST. Works just like [envify](https://github.com/hughsk/envify) but much faster.
+
+## Gotchas
+
+* Doesn't handle broken syntax.
+* Doesn't look inside embedded expressions in template strings.
+  - **this won't work:**
+  ```js
+  console.log(`the current env is ${process.env.NODE_ENV}`);
+  ```
+* Doesn't replace oddly-spaced or oddly-commented expressions.
+  - **this won't work:**
+  ```js
+  console.log(process./*won't*/env./*work*/NODE_ENV);
+  ```
+
+## Usage/Options
+
+loose-envify has the exact same interface as [envify](https://github.com/hughsk/envify), including the CLI.
+

+
+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:
+
+<img width="647" alt="screen shot 2017-08-08 at 12 53 04 pm" src="https://user-images.githubusercontent.com/71256/29091703-a6302cdc-7c38-11e7-8304-7c0b3bc600cd.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 38 pm" src="https://user-images.githubusercontent.com/71256/29091700-a62a6888-7c38-11e7-800b-db911291ca2b.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 25 pm" src="https://user-images.githubusercontent.com/71256/29091701-a62ea114-7c38-11e7-826a-2692bedca740.png">
+
+#### 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.

+[![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`
