-
-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('hello, world!')
- 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/
-```

- * // 'new' is optional
- * y = BigNumber(x) // '123.4567'
- * ```
- *
- * If `n` is a base 10 value it can be in normal (fixed-point) or exponential notation.
- * Values in other bases must be in normal notation. Values in any base can have fraction digits,
- * i.e. digits after the decimal point.
- *
- * ```ts
- * new BigNumber(43210) // '43210'
- * new BigNumber('4.321e+4') // '43210'
- * new BigNumber('-735.0918e-430') // '-7.350918e-428'
- * new BigNumber('123412421.234324', 5) // '607236.557696'
- * ```
- *
- * Signed `0`, signed `Infinity` and `NaN` are supported.

- * new BigNumber(NaN) // 'NaN'
- * new BigNumber(-0) // '0'
- * new BigNumber('.5') // '0.5'
- * new BigNumber('+2') // '2'
- * ```
- *
- * String values in hexadecimal literal form, e.g. `'0xff'`, are valid, as are string values with
- * the octal and binary prefixs `'0o'` and `'0b'`. String values in octal literal form without the
- * prefix will be interpreted as decimals, e.g. `'011'` is interpreted as 11, not 9.
- *
- * ```ts
- * new BigNumber(-10110100.1, 2) // '-180.5'
- * new BigNumber('-0b10110100.1') // '-180.5'
- * new BigNumber('ff.8', 16) // '255.5'
- * new BigNumber('0xff.8') // '255.5'
- * ```
- *
- * If a base is specified, `n` is rounded according to the current `DECIMAL_PLACES` and
- * `ROUNDING_MODE` settings. This includes base 10, so don't include a `base` parameter for decimal
- * values unless this behaviour is desired.
- *
- * ```ts
- * BigNumber.config({ DECIMAL_PLACES: 5 })
- * new BigNumber(1.23456789) // '1.23456789'
- * new BigNumber(1.23456789, 10) // '1.23457'
- * ```
- *
- * An error is thrown if `base` is invalid.
- *
- * There is no limit to the number of digits of a value of type string (other than that of
- * JavaScript's maximum array size). See `RANGE` to set the maximum and minimum possible exponent
- * value of a BigNumber.
- *
- * ```ts
- * new BigNumber('5032485723458348569331745.33434346346912144534543')
- * new BigNumber('4.321e10000000')
- * ```
- *
- * BigNumber `NaN` is returned if `n` is invalid (unless `BigNumber.DEBUG` is `true`, see below).
- *
- * ```ts
- * new BigNumber('.1*') // 'NaN'
- * new BigNumber('blurgh') // 'NaN'
- * new BigNumber(9, 2) // 'NaN'
- * ```
- *
- * To aid in debugging, if `BigNumber.DEBUG` is `true` then an error will be thrown on an
- * invalid `n`. An error will also be thrown if `n` is of type number with more than 15
- * significant digits, as calling `toString` or `valueOf` on these numbers may not result in the
- * intended value.
- *
- * ```ts
- * console.log(823456789123456.3) // 823456789123456.2
- * new BigNumber(823456789123456.3) // '823456789123456.2'

- *
- * If specified, `message` will be appended to the message provided by the`AssertionError` if the `fn` call fails to throw or in case the error validation

- * // Using nested objects requires all properties to be present. Otherwise
- * // the validation is going to fail.

- * // Using regular expressions to validate error properties:
- * throws(
- * () => {
- * throw err;

- * // It is not possible to use regular expressions for nested properties!

- * // The `reg` property contains a regular expression and only if the
- * // validation object contains an identical regular expression, it is going
- * // to pass.
- * reg: /abc/i
- * }
- * );
- *
- * // Fails due to the different `message` and `name` properties:
- * throws(
- * () => {

- * throw otherErr;
- * },
- * // The error's `message` and `name` properties will also be checked when using
- * // an error as validation object.
- * err
- * );
- * ```
- *
- * Validate instanceof using constructor:
- *
- * ```js
- * import assert from 'assert/strict';
- *
- * assert.throws(
- * () => {
- * throw new Error('Wrong value');
- * },
- * Error
- * );
- * ```
- *
- * Validate error message using [`RegExp`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions):
- *
- * Using a regular expression runs `.toString` on the error object, and will
- * therefore also include the error name.
- *
- * ```js
- * import assert from 'assert/strict';
- *
- * assert.throws(
- * () => {
- * throw new Error('Wrong value');
- * },
- * /^Error: Wrong value$/
- * );
- * ```
- *
- * Custom error validation:
- *
- * The function must return `true` to indicate all internal validations passed.
- * It will otherwise fail with an `AssertionError`.
- *
- * ```js
- * import assert from 'assert/strict';
- *
- * assert.throws(
- * () => {
- * throw new Error('Wrong value');
- * },
- * (err) => {
- * assert(err instanceof Error);
- * assert(/value/.test(err));
- * // Avoid returning anything from validation functions besides `true`.
- * // Otherwise, it's not clear what part of the validation failed. Instead,
- * // throw an error about the specific validation that failed (as done in this
- * // example) and add as much helpful debugging information to that error as
- * // possible.
- * return true;
- * },
- * 'unexpected error'
- * );
- * ```
- *
- * `error` cannot be a string. If a string is provided as the second
- * argument, then `error` is assumed to be omitted and the string will be used for`message` instead. This can lead to easy-to-miss mistakes. Using the same
- * message as the thrown error message is going to result in an`ERR_AMBIGUOUS_ARGUMENT` error. Please read the example below carefully if using
- * a string as the second argument gets considered:
- *
- * ```js
- * import assert from 'assert/strict';
- *
- * function throwingFirst() {
- * throw new Error('First');
- * }
- *
- * function throwingSecond() {

- *

-/**
- * `Buffer` objects are used to represent a fixed-length sequence of bytes. Many
- * Node.js APIs support `Buffer`s.
- *
- * The `Buffer` class is a subclass of JavaScript's [`Uint8Array`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array) class and
- * extends it with methods that cover additional use cases. Node.js APIs accept
- * plain [`Uint8Array`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array) s wherever `Buffer`s are supported as well.
- *
- * While the `Buffer` class is available within the global scope, it is still
- * recommended to explicitly reference it via an import or require statement.
- *
- * ```js
- * import { Buffer } from 'buffer';
- *
- * // Creates a zero-filled Buffer of length 10.
- * const buf1 = Buffer.alloc(10);
- *
- * // Creates a Buffer of length 10,
- * // filled with bytes which all have the value `1`.
- * const buf2 = Buffer.alloc(10, 1);
- *
- * // Creates an uninitialized buffer of length 10.
- * // This is faster than calling Buffer.alloc() but the returned
- * // Buffer instance might contain old data that needs to be
- * // overwritten using fill(), write(), or other functions that fill the Buffer's
- * // contents.
- * const buf3 = Buffer.allocUnsafe(10);
- *
- * // Creates a Buffer containing the bytes [1, 2, 3].
- * const buf4 = Buffer.from([1, 2, 3]);
- *
- * // Creates a Buffer containing the bytes [1, 1, 1, 1] – the entries
- * // are all truncated using `(value & 255)` to fit into the range 0–255.
- * const buf5 = Buffer.from([257, 257.5, -255, '1']);
- *
- * // Creates a Buffer containing the UTF-8-encoded bytes for the string 'tést':
- * // [0x74, 0xc3, 0xa9, 0x73, 0x74] (in hexadecimal notation)
- * // [116, 195, 169, 115, 116] (in decimal notation)
- * const buf6 = Buffer.from('tést');
- *
- * // Creates a Buffer containing the Latin-1 bytes [0x74, 0xe9, 0x73, 0x74].
- * const buf7 = Buffer.from('tést', 'latin1');

-/**
- * The `child_process` module provides the ability to spawn subprocesses in
- * a manner that is similar, but not identical, to [`popen(3)`](http://man7.org/linux/man-pages/man3/popen.3.html). This capability
- * is primarily provided by the {@link spawn} function:
- *
- * ```js
- * const { spawn } = require('child_process');
- * const ls = spawn('ls', ['-lh', '/usr']);
- *
- * ls.stdout.on('data', (data) => {
- * console.log(`stdout: ${data}`);
- * });
- *
- * ls.stderr.on('data', (data) => {
- * console.error(`stderr: ${data}`);
- * });
- *
- * ls.on('close', (code) => {
- * console.log(`child process exited with code ${code}`);
- * });
- * ```
- *
- * By default, pipes for `stdin`, `stdout`, and `stderr` are established between
- * the parent Node.js process and the spawned subprocess. These pipes have
- * limited (and platform-specific) capacity. If the subprocess writes to
- * stdout in excess of that limit without the output being captured, the
- * subprocess blocks waiting for the pipe buffer to accept more data. This is
- * identical to the behavior of pipes in the shell. Use the `{ stdio: 'ignore' }`option if the output will not be consumed.
- *
- * The command lookup is performed using the `options.env.PATH` environment
- * variable if `env` is in the `options` object. Otherwise, `process.env.PATH` is
- * used. If `options.env` is set without `PATH`, lookup on Unix is performed
- * on a default search path search of `/usr/bin:/bin` (see your operating system's
- * manual for execvpe/execvp), on Windows the current processes environment
- * variable `PATH` is used.
- *
- * On Windows, environment variables are case-insensitive. Node.js
- * lexicographically sorts the `env` keys and uses the first one that
- * case-insensitively matches. Only first (in lexicographic order) entry will be
- * passed to the subprocess. This might lead to issues on Windows when passing
- * objects to the `env` option that have multiple variants of the same key, such as`PATH` and `Path`.
- *
- * The {@link spawn} method spawns the child process asynchronously,
- * without blocking the Node.js event loop. The {@link spawnSync} function provides equivalent functionality in a synchronous manner that blocks
- * the event loop until the spawned process either exits or is terminated.
- *
- * For convenience, the `child_process` module provides a handful of synchronous
- * and asynchronous alternatives to {@link spawn} and {@link spawnSync}. Each of these alternatives are implemented on
- * top of {@link spawn} or {@link spawnSync}.
- *
- * * {@link exec}: spawns a shell and runs a command within that
- * shell, passing the `stdout` and `stderr` to a callback function when
- * complete.
- * * {@link execFile}: similar to {@link exec} except
- * that it spawns the command directly without first spawning a shell by
- * default.
- * * {@link fork}: spawns a new Node.js process and invokes a
- * specified module with an IPC communication channel established that allows
- * sending messages between parent and child.
- * * {@link execSync}: a synchronous version of {@link exec} that will block the Node.js event loop.
- * * {@link execFileSync}: a synchronous version of {@link execFile} that will block the Node.js event loop.
- *
- * For certain use cases, such as automating shell scripts, the `synchronous counterparts` may be more convenient. In many cases, however,
- * the synchronous methods can have significant impact on performance due to
- * stalling the event loop while spawned processes complete.
- * @see [source](https://github.com/nodejs/node/blob/v18.0.0/lib/child_process.js)

- * be delivered to that process instead which can have unexpected results.
- *
- * While the function is called `kill`, the signal delivered to the child process

- *
- * See [`kill(2)`](http://man7.org/linux/man-pages/man2/kill.2.html) for reference.
- *
- * On Windows, where POSIX signals do not exist, the `signal` argument will be

- * See `Signal Events` for more details.

- * when attempting to kill their parent. This is likely to happen when running a

- *
- * ```js
- * 'use strict';

- /**
- * When an IPC channel has been established between the parent and child (
- * i.e. when using {@link fork}), the `subprocess.send()` method can
- * be used to send messages to the child process. When the child process is a
- * Node.js instance, these messages can be received via the `'message'` event.
- *
- * The message goes through serialization and parsing. The resulting
- * message might not be the same as what is originally sent.
- *
- * For example, in the parent script:
- *
- * ```js
- * const cp = require('child_process');
- * const n = cp.fork(`${__dirname}/sub.js`);
- *
- * n.on('message', (m) => {
- * console.log('PARENT got message:', m);
- * });
- *
- * // Causes the child to print: CHILD got message: { hello: 'world' }
- * n.send({ hello: 'world' });
- * ```
- *
- * And then the child script, `'sub.js'` might look like this:
- *
- * ```js
- * process.on('message', (m) => {
- * console.log('CHILD got message:', m);
- * });
- *
- * // Causes the parent to print: PARENT got message: { foo: 'bar', baz: null }
- * process.send({ foo: 'bar', baz: NaN });
- * ```
- *
- * Child Node.js processes will have a `process.send()` method of their own
- * that allows the child to send messages back to the parent.
- *
- * There is a special case when sending a `{cmd: 'NODE_foo'}` message. Messages
- * containing a `NODE_` prefix in the `cmd` property are reserved for use within
- * Node.js core and will not be emitted in the child's `'message'` event. Rather, such messages are emitted using the`'internalMessage'` event and are consumed internally by Node.js.
- * Applications should avoid using such messages or listening for`'internalMessage'` events as it is subject to change without notice.
- *
- * The optional `sendHandle` argument that may be passed to `subprocess.send()` is
- * for passing a TCP server or socket object to the child process. The child will
- * receive the object as the second argument passed to the callback function
- * registered on the `'message'` event. Any data that is received
- * and buffered in the socket will not be sent to the child.
- *
- * The optional `callback` is a function that is invoked after the message is
- * sent but before the child may have received it. The function is called with a
- * single argument: `null` on success, or an `Error` object on failure.
- *
- * If no `callback` function is provided and the message cannot be sent, an`'error'` event will be emitted by the `ChildProcess` object. This can
- * happen, for instance, when the child process has already exited.
- *
- * `subprocess.send()` will return `false` if the channel has closed or when the
- * backlog of unsent messages exceeds a threshold that makes it unwise to send
- * more. Otherwise, the method returns `true`. The `callback` function can be
- * used to implement flow control.
- *
- * #### Example: sending a server object
- *
- * The `sendHandle` argument can be used, for instance, to pass the handle of
- * a TCP server object to the child process as illustrated in the example below:
- *
- * ```js
- * const subprocess = require('child_process').fork('subprocess.js');
- *
- * // Open up the server object and send the handle.
- * const server = require('net').createServer();
- * server.on('connection', (socket) => {
- * socket.end('handled by parent');
- * });
- * server.listen(1337, () => {
- * subprocess.send('server', server);
- * });
- * ```
- *
- * The child would then receive the server object as:
- *
- * ```js
- * process.on('message', (m, server) => {
- * if (m === 'server') {
- * server.on('connection', (socket) => {
- * socket.end('handled by child');
- * });
- * }
- * });
- * ```
- *
- * Once the server is now shared between the parent and child, some connections
- * can be handled by the parent and some by the child.
- *
- * While the example above uses a server created using the `net` module, `dgram`module servers use exactly the same workflow with the exceptions of listening on
- * a `'message'` event instead of `'connection'` and using `server.bind()` instead
- * of `server.listen()`. This is, however, currently only supported on Unix
- * platforms.
- *
- * #### Example: sending a socket object
- *
- * Similarly, the `sendHandler` argument can be used to pass the handle of a
- * socket to the child process. The example below spawns two children that each
- * handle connections with "normal" or "special" priority:
- *
- * ```js
- * const { fork } = require('child_process');
- * const normal = fork('subprocess.js', ['normal']);
- * const special = fork('subprocess.js', ['special']);
- *
- * // Open up the server and send sockets to child. Use pauseOnConnect to prevent
- * // the sockets from being read before they are sent to the child process.
- * const server = require('net').createServer({ pauseOnConnect: true });
- * server.on('connection', (socket) => {
- *
- * // If this is special priority...
- * if (socket.remoteAddress === '74.125.127.100') {
- * special.send('socket', socket);
- * return;
- * }
- * // This is normal priority.
- * normal.send('socket', socket);
- * });
- * server.listen(1337);
- * ```
- *
- * The `subprocess.js` would receive the socket handle as the second argument
- * passed to the event callback function:
- *
- * ```js
- * process.on('message', (m, socket) => {
- * if (m === 'socket') {
- * if (socket) {
- * // Check that the client socket exists.
- * // It is possible for the socket to be closed between the time it is
- * // sent and the time it is received in the child process.
- * socket.end(`Request handled with ${process.argv[2]} priority`);
- * }
- * }
- * });
- * ```
- *
- * Do not use `.maxConnections` on a socket that has been passed to a subprocess.
- * The parent cannot track when the socket is destroyed.
- *
- * Any `'message'` handlers in the subprocess should verify that `socket` exists,
- * as the connection may have been closed during the time it takes to send the
- * connection to the child.
- * @since v0.5.9
- * @param options The `options` argument, if present, is an object used to parameterize the sending of certain types of handles. `options` supports the following properties:

- * The `child_process.spawn()` method spawns a new process using the given`command`, with command-line arguments in `args`. If omitted, `args` defaults

- *
- * **If the `shell` option is enabled, do not pass unsanitized user input to this**
- * **function. Any input containing shell metacharacters may be used to trigger**
- * **arbitrary command execution.**
- *
- * A third argument may be used to specify additional options, with these defaults:
- *
- * ```js
- * const defaults = {
- * cwd: undefined,
- * env: process.env
- * };
- * ```
- *
- * Use `cwd` to specify the working directory from which the process is spawned.
- * If not given, the default is to inherit the current working directory. If given,
- * but the path does not exist, the child process emits an `ENOENT` error
- * and exits immediately. `ENOENT` is also emitted when the command
- * does not exist.
- *
- * Use `env` to specify environment variables that will be visible to the new
- * process, the default is `process.env`.
- *
- * `undefined` values in `env` will be ignored.
- *
- * Example of running `ls -lh /usr`, capturing `stdout`, `stderr`, and the
- * exit code:
- *
- * ```js
- * const { spawn } = require('child_process');
- * const ls = spawn('ls', ['-lh', '/usr']);
- *
- * ls.stdout.on('data', (data) => {

- * });
- *
- * ls.on('close', (code) => {
- * console.log(`child process exited with code ${code}`);
- * });
- * ```
- *
- * Example: A very elaborate way to run `ps ax | grep ssh`
- *
- * ```js
- * const { spawn } = require('child_process');
- * const ps = spawn('ps', ['ax']);
- * const grep = spawn('grep', ['ssh']);
- *
- * ps.stdout.on('data', (data) => {

- *
- * ps.on('close', (code) => {
- * if (code !== 0) {

- *
- * Example of checking for failed `spawn`:

- * const { spawn } = require('child_process');
- * const subprocess = spawn('bad_command');
- *
- * subprocess.on('error', (err) => {
- * console.error('Failed to start subprocess.');
- * });
- * ```
- *
- * Certain platforms (macOS, Linux) will use the value of `argv[0]` for the process
- * title while others (Windows, SunOS) will use `command`.
- *
- * Node.js currently overwrites `argv[0]` with `process.execPath` on startup, so`process.argv[0]` in a Node.js child process will not match the `argv0`parameter passed to `spawn` from the parent,
- * retrieve it with the`process.argv0` property instead.
- *
- * If the `signal` option is enabled, calling `.abort()` on the corresponding`AbortController` is similar to calling `.kill()` on the child process except

- *
- * ```js
- * const { spawn } = require('child_process');
- * const controller = new AbortController();
- * const { signal } = controller;
- * const grep = spawn('grep', ['ssh'], { signal });

- * need to be dealt with accordingly:
- *
- * ```js

- * exec('echo "The \\$HOME variable is $HOME"');
- * // The $HOME variable is escaped in the first instance, but not in the second.
- * ```
- *
- * **Never pass unsanitized user input to this function. Any input containing shell**
- * **metacharacters may be used to trigger arbitrary command execution.**
- *
- * If a `callback` function is provided, it is called with the arguments`(error, stdout, stderr)`. On success, `error` will be `null`. On error,`error` will be an instance of `Error`. The
- * `error.code` property will be
- * the exit code of the process. By convention, any exit code other than `0`indicates an error. `error.signal` will be the signal that terminated the
- * process.
- *
- * The `stdout` and `stderr` arguments passed to the callback will contain the
- * stdout and stderr output of the child process. By default, Node.js will decode
- * the output as UTF-8 and pass strings to the callback. The `encoding` option
- * can be used to specify the character encoding used to decode the stdout and
- * stderr output. If `encoding` is `'buffer'`, or an unrecognized character
- * encoding, `Buffer` objects will be passed to the callback instead.
- *
- * ```js
- * const { exec } = require('child_process');
- * exec('cat *.js missing_file | wc -l', (error, stdout, stderr) => {
- * if (error) {
- * console.error(`exec error: ${error}`);
- * return;
- * }
- * console.log(`stdout: ${stdout}`);
- * console.error(`stderr: ${stderr}`);
- * });
- * ```
- *
- * If `timeout` is greater than `0`, the parent will send the signal
- * identified by the `killSignal` property (the default is `'SIGTERM'`) if the
- * child runs longer than `timeout` milliseconds.
- *
- * Unlike the [`exec(3)`](http://man7.org/linux/man-pages/man3/exec.3.html) POSIX system call, `child_process.exec()` does not replace
- * the existing process and uses a shell to execute the command.
- *
- * If this method is invoked as its `util.promisify()` ed version, it returns
- * a `Promise` for an `Object` with `stdout` and `stderr` properties. The returned`ChildProcess` instance is attached to the `Promise` as a `child` property. In
- * case of an error (including any error resulting in an exit code other than 0), a
- * rejected promise is returned, with the same `error` object given in the
- * callback, but with two additional properties `stdout` and `stderr`.
- *
- * ```js
- * const util = require('util');

- * The `child_process.fork()` method is a special case of {@link spawn} used specifically to spawn new Node.js processes.
- * Like {@link spawn}, a `ChildProcess` object is returned. The
- * returned `ChildProcess` will have an additional communication channel
- * built-in that allows messages to be passed back and forth between the parent and
- * child. See `subprocess.send()` for details.
- *
- * Keep in mind that spawned Node.js child processes are
- * independent of the parent with exception of the IPC communication channel
- * that is established between the two. Each process has its own memory, with
- * their own V8 instances. Because of the additional resource allocations
- * required, spawning a large number of child Node.js processes is not
- * recommended.
- *
- * By default, `child_process.fork()` will spawn new Node.js instances using the `process.execPath` of the parent process. The `execPath` property in the`options` object allows for an alternative
- * execution path to be used.
- *
- * Node.js processes launched with a custom `execPath` will communicate with the
- * parent process using the file descriptor (fd) identified using the
- * environment variable `NODE_CHANNEL_FD` on the child process.
- *
- * Unlike the [`fork(2)`](http://man7.org/linux/man-pages/man2/fork.2.html) POSIX system call, `child_process.fork()` does not clone the
- * current process.
- *
- * The `shell` option available in {@link spawn} is not supported by`child_process.fork()` and will be ignored if set.
- *
- * If the `signal` option is enabled, calling `.abort()` on the corresponding`AbortController` is similar to calling `.kill()` on the child process except
- * the error passed to the callback will be an `AbortError`:
- *
- * ```js
- * if (process.argv[2] === 'child') {
- * setTimeout(() => {
- * console.log(`Hello from ${process.argv[2]}!`);
- * }, 1_000);
- * } else {

- * Clusters of Node.js processes can be used to run multiple instances of Node.js
- * that can distribute workloads among their application threads. When process
- * isolation is not needed, use the `worker_threads` module instead, which
- * allows running multiple application threads within a single Node.js instance.
- *
- * The cluster module allows easy creation of child processes that all share
- * server ports.
- *
- * ```js
- * import cluster from 'cluster';
- * import http from 'http';
- * import { cpus } from 'os';
- * import process from 'process';
- *
- * const numCPUs = cpus().length;
- *
- * if (cluster.isPrimary) {
- * console.log(`Primary ${process.pid} is running`);
- *
- * // Fork workers.
- * for (let i = 0; i < numCPUs; i++) {
- * cluster.fork();
- * }
- *
- * cluster.on('exit', (worker, code, signal) => {
- * console.log(`worker ${worker.process.pid} died`);
- * });
- * } else {
- * // Workers can share any TCP connection
- * // In this case it is an HTTP server
- * http.createServer((req, res) => {
- * res.writeHead(200);
- * res.end('hello world\n');
- * }).listen(8000);
- *
- * console.log(`Worker ${process.pid} started`);
- * }
- * ```
- *
- * Running Node.js will now share port 8000 between the workers:
- *
- * ```console
- * $ node server.js
- * Primary 3596 is running
- * Worker 4324 started
- * Worker 4520 started
- * Worker 6056 started
- * Worker 5644 started
- * ```
- *
- * On Windows, it is not yet possible to set up a named pipe server in a worker.

- * The `console` module provides a simple debugging console that is similar to the
- * JavaScript console mechanism provided by web browsers.
- *
- * The module exports two specific components:
- *
- * * A `Console` class with methods such as `console.log()`, `console.error()` and`console.warn()` that can be used to write to any Node.js stream.
- * * A global `console` instance configured to write to `process.stdout` and `process.stderr`. The global `console` can be used without calling`require('console')`.
- *
- * _**Warning**_: The global console object's methods are neither consistently
- * synchronous like the browser APIs they resemble, nor are they consistently
- * asynchronous like all other Node.js streams. See the `note on process I/O` for
- * more information.
- *
- * Example using the global `console`:
- *
- * ```js
- * console.log('hello world');
- * // Prints: hello world, to stdout
- * console.log('hello %s', 'world');
- * // Prints: hello world, to stdout
- * console.error(new Error('Whoops, something bad happened'));
- * // Prints error message and stack trace to stderr:
- * // Error: Whoops, something bad happened

- * const name = 'Will Robinson';
- * console.warn(`Danger ${name}! Danger!`);
- * // Prints: Danger Will Robinson! Danger!, to stderr
