-
-### 功能简介
-
-跨平台仓库代码同步服务用于不同代码托管平台之间的仓库代码双向同步功能。用户将不同平台的仓库分支进行绑定，当任意仓库分支有push事件被webhook监听时，代码推送将实时自动同步至另一个仓库，以实现不同平台之间分支、提交信息的自动同步（代码托管平台仅限于github与gitee）。
-
-
-![1.同步流程](../../static/img/reposyncer/1.同步流程.png)
-
-同步服务既满足双平台代码库分支同步需求，也支持最多创建三个平台的代码仓库同步，如下图所示
-
-![2.同步方式](../../static/img/reposyncer/2.同步方式.png)
-
-### 配置双向同步
-
-1、进入需要创建同步的代码库“服务”tab，开通跨平台代码同步服务。
-
-![3.开启跨平台服务](../../static/img/reposyncer/3.开启跨平台服务.png)
-
-2、配置跨平台的同步仓库，支持github和gitee。需输入代码库地址（git地址和网站访问地址均支持），以及配置对应token用于授权同步，此处须注意token的权限以及是否过期。<br />
-Github配置方式为：个人头像→Settings→Developer Settings→Personal access tokens (classic)→Generate new token→勾选repo按钮→保存<br />
-Gitee配置方式为：个人头像→设置→私人令牌→生成新令牌→勾选projects权限→提交
-
-![4.配置同步仓库](../../static/img/reposyncer/4.配置同步仓库.jpg)
-
-3、在首次创建同步仓库时，需要用户手动在目标仓库的代码库创建一条webhook，用于监听仓库push事件，从而向其他同步仓库推送代码完成同步，同步步骤如下：
-
-①点击“复制链接”按钮，复制平台用于接收webhook请求的地址
-
-![5.配置webhook](../../static/img/reposyncer/5.配置webhook.jpg)
-
-
-②访问点击前往按钮前往目标仓库webhook页新建一个webhook，以github为例
-
-![6.webhook示例](../../static/img/reposyncer/6.webhook示例.png)
-
-③粘贴链接，并确保该webhook支持push事件的监听，并已经成功激活
-
-![7.webhook配置规则](../../static/img/reposyncer/7.webhook配置规则.png)
-
-4、完成仓库配置绑定后，需要绑定这两个仓库的指定同步分支，建立首次同步方向。<font color="red">注：首次同步的策略为单向代码强推，请谨慎选择同步方向开启同步以避免代码被覆盖</font>
-
-![8.绑定分支](../../static/img/reposyncer/8.绑定分支.jpg)
-
-5、完成分支的绑定，在绑定后会根据选择的同步方向立即执行一次同步。后续webhook监听到任意分支有代码推送，会实时向另一个绑定分支同步代码推送代码
-
-![9.确认绑定](../../static/img/reposyncer/9.确认绑定.jpg)
-
- ### 管理同步分支
-
-
-同步分支配置完成后，用户可在同步分支列表完成一系列操作<br />
-①添加绑定新的同步分支，如两个仓库已建立了Develop分支，需要再建立feature分支的同步，可实时添加<br />
-②查询两个分支间最新一次的同步时间及同步状态。若同步失败，可在同步记录中查询日志分析失败原因<br />
-③添加同步仓库，若已绑定了github的同步仓库，想在gitee导入一个仓库进行开发，并想完成实时多个仓库的分支同步。<br />
-④查看同步配置，可用于查询同步仓库的地址，GitLink 用于接受第三方webhook请求的地址，以及更新token。以防token过期<br />
-⑤查询同步记录，包括查看历次同步的代码变更方，同步时间，同步状态及对应commt id，查询同步日志。<br />
-⑥中止、开启同步，相当于同步开关，可随时启停
-
-![同步分支管理](../../static/img/reposyncer/同步分支管理.png)
-
- ### 注意事项
-
-1、在建立同步时，工具将根据用户选择的首次同步方向强行推送一次代码，请谨慎选择同步方向，以规避代码被覆盖的风险。同步建立之后，哪一方push事件触发被webhook监听，将同步至另一方，请勿在多仓库同时提交代码，以防出现冲突<br />
-2、目前仅支持个人仓库的同步，组织仓库的同步暂不支持，敬请期待<br />
-3、在配置过程中，请仔细检查token的权限，是否已包含了仓库读写。同时请检查token是否已过期，若过期请点击【查看同步配置】按钮进入页面更新此token<br />
-4、在配置过程中，请仔细检查其他平台webhook的监听事件中是否包含了push事件，以及webhook是否已激活

-
-2. 问：提交错误（Committing Mistakes）：可能会不小心提交了错误的文件或信息。
-
-   答：可以使用 git commit --amend 命令来修改最近一次提交，或者使用交互式 rebase 来修改历史记录。
-
-3. 问：丢失提交（Lost Commits）：有时可能会意外丢失提交记录。
-   答：可以使用 git reflog 命令来查找丢失的提交，然后将其恢复。
-
-4. 问：分支管理问题（Branch Management Issues）：可能会遇到创建、合并、删除分支时的问题。
-   答：确保在操作分支之前了解清楚分支的当前状态，并使用正确的命令来执行相应的操作。

-
-Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
-Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
-
-In addition to negotiator, it allows:
-
- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
-  as well as `('text/html', 'application/json')`.
- Allows type shorthands such as `json`.
- Returns `false` when no types match
- Treats non-existent headers as `*`
-
-## 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 accepts
-```
-
-## API
-
-```js
-var accepts = require('accepts')
-```
-
-### accepts(req)
-
-Create a new `Accepts` object for the given `req`.
-
-#### .charset(charsets)
-
-Return the first accepted charset. If nothing in `charsets` is accepted,
-then `false` is returned.
-
-#### .charsets()
-
-Return the charsets that the request accepts, in the order of the client's
-preference (most preferred first).
-
-#### .encoding(encodings)
-
-Return the first accepted encoding. If nothing in `encodings` is accepted,
-then `false` is returned.
-
-#### .encodings()
-
-Return the encodings that the request accepts, in the order of the client's
-preference (most preferred first).
-
-#### .language(languages)
-
-Return the first accepted language. If nothing in `languages` is accepted,
-then `false` is returned.
-
-#### .languages()
-
-Return the languages that the request accepts, in the order of the client's
-preference (most preferred first).
-
-#### .type(types)
-
-Return the first accepted type (and it is returned as the same text as what
-appears in the `types` array). If nothing in `types` is accepted, then `false`
-is returned.
-
-The `types` array can contain full MIME types or file extensions. Any value
-that is not a full MIME types is passed to `require('mime-types').lookup`.
-
-#### .types()
-
-Return the types that the request accepts, in the order of the client's
-preference (most preferred first).
-
-## Examples
-
-### Simple type negotiation
-
-This simple example shows how to use `accepts` to return a different typed
-respond body based on what the client wants to accept. The server lists it's
-preferences in order and will get back the best match between the client and
-server.
-
-```js
-var accepts = require('accepts')
-var http = require('http')
-
-function app (req, res) {
-  var accept = accepts(req)
-
-  // the order of this list is significant; should be server preferred order
-  switch (accept.type(['json', 'html'])) {
-    case 'json':
-      res.setHeader('Content-Type', 'application/json')
-      res.write('{"hello":"world!"}')
-      break
-    case 'html':
-      res.setHeader('Content-Type', 'text/html')
-      res.write('<b>hello, world!</b>')
-      break
-    default:
-      // the fallback is text/plain, so no need to specify it above
-      res.setHeader('Content-Type', 'text/plain')
-      res.write('hello, world!')
-      break
-  }
-
-  res.end()
-}
-
-http.createServer(app).listen(3000)
-```
-
-You can test this out with the cURL program:
-```sh
-curl -I -H'Accept: text/html' http://localhost:3000/
-```

-Node.js body parsing middleware.
-
-Parse incoming request bodies in a middleware before your handlers, available
-under the `req.body` property.
-
-**Note** As `req.body`'s shape is based on user-controlled input, all
-properties and values in this object are untrusted and should be validated
-before trusting. For example, `req.body.foo.toString()` may fail in multiple
-ways, for example the `foo` property may not be there or may not be a string,
-and `toString` may not be a function and instead a string or other user input.

-[Learn about the anatomy of an HTTP transaction in Node.js](https://nodejs.org/en/docs/guides/anatomy-of-an-http-transaction/).
-
-_This does not handle multipart bodies_, due to their complex and typically
-large nature. For multipart bodies, you may be interested in the following
-modules:
-
-  * [busboy](https://www.npmjs.org/package/busboy#readme) and
-    [connect-busboy](https://www.npmjs.org/package/connect-busboy#readme)
-  * [multiparty](https://www.npmjs.org/package/multiparty#readme) and
-    [connect-multiparty](https://www.npmjs.org/package/connect-multiparty#readme)
-  * [formidable](https://www.npmjs.org/package/formidable#readme)
-  * [multer](https://www.npmjs.org/package/multer#readme)
-
-This module provides the following parsers:
-
-  * [JSON body parser](#bodyparserjsonoptions)
-  * [Raw body parser](#bodyparserrawoptions)
-  * [Text body parser](#bodyparsertextoptions)
-  * [URL-encoded form body parser](#bodyparserurlencodedoptions)
-
-Other body parsers you might be interested in:
-
- [body](https://www.npmjs.org/package/body#readme)
- [co-body](https://www.npmjs.org/package/co-body#readme)
-
-## Installation
-
-```sh
-$ npm install body-parser
-```
-
-## API
-
-```js
-var bodyParser = require('body-parser')
-```
-
-The `bodyParser` object exposes various factories to create middlewares. All
-middlewares will populate the `req.body` property with the parsed body when
-the `Content-Type` request header matches the `type` option, or an empty
-object (`{}`) if there was no body to parse, the `Content-Type` was not matched,
-or an error occurred.
-
-The various errors returned by this module are described in the
-[errors section](#errors).
-
-### bodyParser.json([options])
-
-Returns middleware that only parses `json` and only looks at requests where
-the `Content-Type` header matches the `type` option. This parser accepts any
-Unicode encoding of the body and supports automatic inflation of `gzip` and
-`deflate` encodings.
-
-A new `body` object containing the parsed data is populated on the `request`
-object after the middleware (i.e. `req.body`).
-
-#### Options
-
-The `json` function takes an optional `options` object that may contain any of
-the following keys:
-
-##### inflate
-
-When set to `true`, then deflated (compressed) bodies will be inflated; when
-`false`, deflated bodies are rejected. Defaults to `true`.
-
-##### limit
-
-Controls the maximum request body size. If this is a number, then the value
-specifies the number of bytes; if it is a string, the value is passed to the
-[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
-to `'100kb'`.
-
-##### reviver
-
-The `reviver` option is passed directly to `JSON.parse` as the second
-argument. You can find more information on this argument
-[in the MDN documentation about JSON.parse](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Example.3A_Using_the_reviver_parameter).
-
-##### strict
-
-When set to `true`, will only accept arrays and objects; when `false` will
-accept anything `JSON.parse` accepts. Defaults to `true`.
-
-##### type
-
-The `type` option is used to determine what media type the middleware will
-parse. This option can be a string, array of strings, or a function. If not a
-function, `type` option is passed directly to the
-[type-is](https://www.npmjs.org/package/type-is#readme) library and this can
-be an extension name (like `json`), a mime type (like `application/json`), or
-a mime type with a wildcard (like `*/*` or `*/json`). If a function, the `type`
-option is called as `fn(req)` and the request is parsed if it returns a truthy
-value. Defaults to `application/json`.
-
-##### verify
-
-The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
-where `buf` is a `Buffer` of the raw request body and `encoding` is the
-encoding of the request. The parsing can be aborted by throwing an error.
-
-### bodyParser.raw([options])
-
-Returns middleware that parses all bodies as a `Buffer` and only looks at
-requests where the `Content-Type` header matches the `type` option. This
-parser supports automatic inflation of `gzip` and `deflate` encodings.
-
-A new `body` object containing the parsed data is populated on the `request`
-object after the middleware (i.e. `req.body`). This will be a `Buffer` object
-of the body.
-
-#### Options
-
-The `raw` function takes an optional `options` object that may contain any of
-the following keys:
-
-##### inflate
-
-When set to `true`, then deflated (compressed) bodies will be inflated; when
-`false`, deflated bodies are rejected. Defaults to `true`.
-
-##### limit
-
-Controls the maximum request body size. If this is a number, then the value
-specifies the number of bytes; if it is a string, the value is passed to the
-[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
-to `'100kb'`.
-
-##### type
-
-The `type` option is used to determine what media type the middleware will
-parse. This option can be a string, array of strings, or a function.
-If not a function, `type` option is passed directly to the
-[type-is](https://www.npmjs.org/package/type-is#readme) library and this
-can be an extension name (like `bin`), a mime type (like
-`application/octet-stream`), or a mime type with a wildcard (like `*/*` or
-`application/*`). If a function, the `type` option is called as `fn(req)`
-and the request is parsed if it returns a truthy value. Defaults to
-`application/octet-stream`.
-
-##### verify
-
-The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
-where `buf` is a `Buffer` of the raw request body and `encoding` is the
-encoding of the request. The parsing can be aborted by throwing an error.
-
-### bodyParser.text([options])
-
-Returns middleware that parses all bodies as a string and only looks at
-requests where the `Content-Type` header matches the `type` option. This
-parser supports automatic inflation of `gzip` and `deflate` encodings.
-
-A new `body` string containing the parsed data is populated on the `request`
-object after the middleware (i.e. `req.body`). This will be a string of the
-body.
-
-#### Options
-
-The `text` function takes an optional `options` object that may contain any of
-the following keys:
-
-##### defaultCharset
-
-Specify the default character set for the text content if the charset is not
-specified in the `Content-Type` header of the request. Defaults to `utf-8`.
-
-##### inflate
-
-When set to `true`, then deflated (compressed) bodies will be inflated; when
-`false`, deflated bodies are rejected. Defaults to `true`.
-
-##### limit
-
-Controls the maximum request body size. If this is a number, then the value
-specifies the number of bytes; if it is a string, the value is passed to the
-[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
-to `'100kb'`.
-
-##### type
-
-The `type` option is used to determine what media type the middleware will
-parse. This option can be a string, array of strings, or a function. If not
-a function, `type` option is passed directly to the
-[type-is](https://www.npmjs.org/package/type-is#readme) library and this can
-be an extension name (like `txt`), a mime type (like `text/plain`), or a mime
-type with a wildcard (like `*/*` or `text/*`). If a function, the `type`
-option is called as `fn(req)` and the request is parsed if it returns a
-truthy value. Defaults to `text/plain`.
-
-##### verify
-
-The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
-where `buf` is a `Buffer` of the raw request body and `encoding` is the
-encoding of the request. The parsing can be aborted by throwing an error.
-
-### bodyParser.urlencoded([options])
-
-Returns middleware that only parses `urlencoded` bodies and only looks at
-requests where the `Content-Type` header matches the `type` option. This
-parser accepts only UTF-8 encoding of the body and supports automatic
-inflation of `gzip` and `deflate` encodings.
-
-A new `body` object containing the parsed data is populated on the `request`
-object after the middleware (i.e. `req.body`). This object will contain
-key-value pairs, where the value can be a string or array (when `extended` is
-`false`), or any type (when `extended` is `true`).
-
-#### Options
-
-The `urlencoded` function takes an optional `options` object that may contain
-any of the following keys:
-
-##### extended
-
-The `extended` option allows to choose between parsing the URL-encoded data
-with the `querystring` library (when `false`) or the `qs` library (when
-`true`). The "extended" syntax allows for rich objects and arrays to be
-encoded into the URL-encoded format, allowing for a JSON-like experience
-with URL-encoded. For more information, please
-[see the qs library](https://www.npmjs.org/package/qs#readme).
-
-Defaults to `true`, but using the default has been deprecated. Please
-research into the difference between `qs` and `querystring` and choose the
-appropriate setting.
-
-##### inflate
-
-When set to `true`, then deflated (compressed) bodies will be inflated; when
-`false`, deflated bodies are rejected. Defaults to `true`.
-
-##### limit
-
-Controls the maximum request body size. If this is a number, then the value
-specifies the number of bytes; if it is a string, the value is passed to the
-[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
-to `'100kb'`.
-
-##### parameterLimit
-
-The `parameterLimit` option controls the maximum number of parameters that
-are allowed in the URL-encoded data. If a request contains more parameters
-than this value, a 413 will be returned to the client. Defaults to `1000`.
-
-##### type
-
-The `type` option is used to determine what media type the middleware will
-parse. This option can be a string, array of strings, or a function. If not
-a function, `type` option is passed directly to the
-[type-is](https://www.npmjs.org/package/type-is#readme) library and this can
-be an extension name (like `urlencoded`), a mime type (like
-`application/x-www-form-urlencoded`), or a mime type with a wildcard (like
-`*/x-www-form-urlencoded`). If a function, the `type` option is called as
-`fn(req)` and the request is parsed if it returns a truthy value. Defaults
-to `application/x-www-form-urlencoded`.
-
-##### verify
-
-The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
-where `buf` is a `Buffer` of the raw request body and `encoding` is the
-encoding of the request. The parsing can be aborted by throwing an error.
-
-## Errors
-
-The middlewares provided by this module create errors using the
-[`http-errors` module](https://www.npmjs.com/package/http-errors). The errors
-will typically have a `status`/`statusCode` property that contains the suggested
-HTTP response code, an `expose` property to determine if the `message` property
-should be displayed to the client, a `type` property to determine the type of
-error without matching against the `message`, and a `body` property containing
-the read body, if available.
-
-The following are the common errors created, though any error can come through
-for various reasons.
-
-### content encoding unsupported
-
-This error will occur when the request had a `Content-Encoding` header that
-contained an encoding but the "inflation" option was set to `false`. The
-`status` property is set to `415`, the `type` property is set to
-`'encoding.unsupported'`, and the `charset` property will be set to the
-encoding that is unsupported.
-
-### entity parse failed
-
-This error will occur when the request contained an entity that could not be
-parsed by the middleware. The `status` property is set to `400`, the `type`
-property is set to `'entity.parse.failed'`, and the `body` property is set to
-the entity value that failed parsing.
-
-### entity verify failed
-
-This error will occur when the request contained an entity that could not be
-failed verification by the defined `verify` option. The `status` property is
-set to `403`, the `type` property is set to `'entity.verify.failed'`, and the
-`body` property is set to the entity value that failed verification.
-
-### request aborted
-
-This error will occur when the request is aborted by the client before reading
-the body has finished. The `received` property will be set to the number of
-bytes received before the request was aborted and the `expected` property is
-set to the number of expected bytes. The `status` property is set to `400`
-and `type` property is set to `'request.aborted'`.
-
-### request entity too large
-
-This error will occur when the request body's size is larger than the "limit"
-option. The `limit` property will be set to the byte limit and the `length`
-property will be set to the request body's length. The `status` property is
-set to `413` and the `type` property is set to `'entity.too.large'`.
-
-### request size did not match content length
-
-This error will occur when the request's length did not match the length from
-the `Content-Length` header. This typically occurs when the request is malformed,
-typically when the `Content-Length` header was calculated based on characters
-instead of bytes. The `status` property is set to `400` and the `type` property
-is set to `'request.size.invalid'`.
-
-### stream encoding should not be set
-
-This error will occur when something called the `req.setEncoding` method prior
-to this middleware. This module operates directly on bytes only and you cannot
-call `req.setEncoding` when using this module. The `status` property is set to
-`500` and the `type` property is set to `'stream.encoding.set'`.
-
-### stream is not readable
-
-This error will occur when the request is no longer readable when this middleware
-attempts to read it. This typically means something other than a middleware from
-this module read the request body already and the middleware was also configured to
-read the same request. The `status` property is set to `500` and the `type`
-property is set to `'stream.not.readable'`.
-
-### too many parameters
-
-This error will occur when the content of the request exceeds the configured
-`parameterLimit` for the `urlencoded` parser. The `status` property is set to
-`413` and the `type` property is set to `'parameters.too.many'`.
-
-### unsupported charset "BOGUS"
-
-This error will occur when the request had a charset parameter in the
-`Content-Type` header, but the `iconv-lite` module does not support it OR the
-parser does not support it. The charset is contained in the message as well
-as in the `charset` property. The `status` property is set to `415`, the
-`type` property is set to `'charset.unsupported'`, and the `charset` property
-is set to the charset that is unsupported.
-
-### unsupported content encoding "bogus"
-
-This error will occur when the request had a `Content-Encoding` header that
-contained an unsupported encoding. The encoding is contained in the message
-as well as in the `encoding` property. The `status` property is set to `415`,
-the `type` property is set to `'encoding.unsupported'`, and the `encoding`
-property is set to the encoding that is unsupported.
-
-## Examples
-
-### Express/Connect top-level generic
-
-This example demonstrates adding a generic JSON and URL-encoded parser as a
-top-level middleware, which will parse the bodies of all incoming requests.
-This is the simplest setup.
-
-```js
-var express = require('express')
-var bodyParser = require('body-parser')
-
-var app = express()
-
-// parse application/x-www-form-urlencoded
-app.use(bodyParser.urlencoded({ extended: false }))
-
-// parse application/json
-app.use(bodyParser.json())
-
-app.use(function (req, res) {
-  res.setHeader('Content-Type', 'text/plain')
-  res.write('you posted:\n')
-  res.end(JSON.stringify(req.body, null, 2))
-})
-```
-
-### Express route-specific
-
-This example demonstrates adding body parsers specifically to the routes that
-need them. In general, this is the most recommended way to use body-parser with
-Express.
-
-```js
-var express = require('express')
-var bodyParser = require('body-parser')
-
-var app = express()
-
-// create application/json parser
-var jsonParser = bodyParser.json()
-
-// create application/x-www-form-urlencoded parser
-var urlencodedParser = bodyParser.urlencoded({ extended: false })
-
-// POST /login gets urlencoded bodies
-app.post('/login', urlencodedParser, function (req, res) {
-  res.send('welcome, ' + req.body.username)
-})
-
-// POST /api/users gets JSON bodies
-app.post('/api/users', jsonParser, function (req, res) {
-  // create user in req.body
-})
-```
-
-### Change accepted type for parsers
-
-All the parsers accept a `type` option which allows you to change the
-`Content-Type` that the middleware will parse.
-
-```js
-var express = require('express')
-var bodyParser = require('body-parser')
-
-var app = express()
-
-// parse various different custom JSON types as JSON
-app.use(bodyParser.json({ type: 'application/*+json' }))
-
-// parse some custom thing into a Buffer
-app.use(bodyParser.raw({ type: 'application/vnd.custom-type' }))
-
-// parse an HTML body into a string
-app.use(bodyParser.text({ type: 'text/html' }))
-```

-Utility to parse a string bytes (ex: `1TB`) to bytes (`1099511627776`) and vice-versa.
-
-## 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):
-
-```bash
-$ npm install bytes
-```
-
-## Usage
-
-```js
-var bytes = require('bytes');
-```
-
-#### bytes(number｜string value, [options]): number｜string｜null
-
-Default export function. Delegates to either `bytes.format` or `bytes.parse` based on the type of `value`.
-
-**Arguments**
-
-| Name    | Type     | Description        |
-|---------|----------|--------------------|
-| value   | `number`｜`string` | Number value to format or string value to parse |
-| options | `Object` | Conversion options for `format` |
-
-**Returns**
-
-| Name    | Type             | Description                                     |
-|---------|------------------|-------------------------------------------------|
-| results | `string`｜`number`｜`null` | Return null upon error. Numeric value in bytes, or string value otherwise. |
-
-**Example**
-
-```js
-bytes(1024);
-// output: '1KB'
-
-bytes('1KB');
-// output: 1024
-```
-
-#### bytes.format(number value, [options]): string｜null
-
-Format the given value in bytes into a string. If the value is negative, it is kept as such. If it is a float, it is
- rounded.
-
-**Arguments**
-
-| Name    | Type     | Description        |
-|---------|----------|--------------------|
-| value   | `number` | Value in bytes     |
-| options | `Object` | Conversion options |
-
-**Options**
-
-| Property          | Type   | Description                                                                             |
-|-------------------|--------|-----------------------------------------------------------------------------------------|
-| decimalPlaces | `number`｜`null` | Maximum number of decimal places to include in output. Default value to `2`. |
-| fixedDecimals | `boolean`｜`null` | Whether to always display the maximum number of decimal places. Default value to `false` |
-| thousandsSeparator | `string`｜`null` | Example of values: `' '`, `','` and `'.'`... Default value to `''`. |
-| unit | `string`｜`null` | The unit in which the result will be returned (B/KB/MB/GB/TB). Default value to `''` (which means auto detect). |
-| unitSeparator | `string`｜`null` | Separator to use between number and unit. Default value to `''`. |
-
-**Returns**
-
-| Name    | Type             | Description                                     |
-|---------|------------------|-------------------------------------------------|
-| results | `string`｜`null` | Return null upon error. String value otherwise. |
-
-**Example**
-
-```js
-bytes.format(1024);
-// output: '1KB'
-
-bytes.format(1000);
-// output: '1000B'
-
-bytes.format(1000, {thousandsSeparator: ' '});
-// output: '1 000B'
-
-bytes.format(1024 * 1.7, {decimalPlaces: 0});
-// output: '2KB'
-
-bytes.format(1024, {unitSeparator: ' '});
-// output: '1 KB'
-```
-
-#### bytes.parse(string｜number value): number｜null
-
-Parse the string value into an integer in bytes. If no unit is given, or `value`
-is a number, it is assumed the value is in bytes.
-
-Supported units and abbreviations are as follows and are case-insensitive:
-
-  * `b` for bytes
-  * `kb` for kilobytes
-  * `mb` for megabytes
-  * `gb` for gigabytes
-  * `tb` for terabytes
-  * `pb` for petabytes
-
-The units are in powers of two, not ten. This means 1kb = 1024b according to this parser.
-
-**Arguments**
-
-| Name          | Type   | Description        |
-|---------------|--------|--------------------|
-| value   | `string`｜`number` | String to parse, or number in bytes.   |
-
-**Returns**
-
-| Name    | Type        | Description             |
-|---------|-------------|-------------------------|
-| results | `number`｜`null` | Return null upon error. Value in bytes otherwise. |
-
-**Example**
-
-```js
-bytes.parse('1KB');
-// output: 1024
-
-bytes.parse('1024');
-// output: 1024
-
-bytes.parse(1024);
-// output: 1024
-```
