+
+This module provides a basic [ndjson](http://ndjson.org/) formatter to be used in __development__. If an
+incoming line looks like it could be a log line from an ndjson logger, in
+particular the [Pino](https://getpino.io/) logging library, then it will apply
+extra formatting by considering things like the log level and timestamp.
+
+A standard Pino log line like:
+
+```
+{"level":30,"time":1522431328992,"msg":"hello world","pid":42,"hostname":"foo","v":1}
+```
+
+Will format to:
+
+```
+[17:35:28.992] INFO (42): hello world
+```
+
+If you landed on this page due to the deprecation of the `prettyPrint` option
+of `pino`, read the [Programmatic Integration](#integration) section.
+
+<a id="example"></a>
+## Example
+
+Using the [example script][exscript] from the Pino module, we can see what the
+prettified logs will look like:

+
+<a id="install"></a>
+## Install
+
+```sh
+$ npm install -g pino-pretty
+```
+
+<a id="usage"></a>
+## Usage
+
+It is recommended to use `pino-pretty` with `pino`
+by piping output to the CLI tool:
+
+```sh
+node app.js | pino-pretty
+```
+
+<a id="cliargs"></a>
+### CLI Arguments
+
+- `--colorize` (`-c`): Adds terminal color escape sequences to the output.
+- `--colorizeObjects` (`-C`): Allows suppressing colorization of objects when set to `false`. In combination with `--singleLine`, this ensures that the end of each line is parsable JSON.
+- `--crlf` (`-f`): Appends carriage return and line feed, instead of just a line
+  feed, to the formatted log line.
+- `--errorProps` (`-e`): When formatting an error object, display this list
+  of properties. The list should be a comma-separated list of properties Default: `''`.
+  Do not use this option if logging from pino@7. Support will be removed from future verions.
+- `--levelFirst` (`-l`): Display the log level name before the logged date and time.
+- `--errorLikeObjectKeys` (`-k`): Define the log keys that are associated with
+  error like objects. Default: `err,error`.
+- `--messageKey` (`-m`): Define the key that contains the main log message.
+  Default: `msg`.
+- `--levelKey` (`--levelKey`): Define the key that contains the level of the log. Nested keys are supported with each property delimited by a dot character (`.`).
+  Keys may be escaped to target property names that contains the delimiter itself:
+  (`--levelKey tags\\.level`).
+  Default: `level`.
+- `--levelLabel` (`-b`): Output the log level using the specified label.
+  Default: `levelLabel`.
+- `--minimumLevel` (`-L`): Hide messages below the specified log level. Accepts a number, `trace`, `debug`, `info`, `warn`, `error`, or `fatal`. If any more filtering is required, consider using [`jq`](https://stedolan.github.io/jq/).
+- `--customLevels` (`-x`): Override default levels with custom levels, e.g. `-x err:99,info:1`
+- `--customColors` (`-X`): Override default colors with custom colors, e.g. `-X err:red,info:blue`
+- `--useOnlyCustomProps` (`-U`): Only use custom levels and colors (if provided) (default: true); else fallback to default levels and colors, e.g. `-U false`
+- `--messageFormat` (`-o`): Format output of message, e.g. `{levelLabel} - {pid} - url:{req.url}` will output message: `INFO - 1123 - url:localhost:3000/test`
+  Default: `false`
+- `--timestampKey` (`-a`): Define the key that contains the log timestamp.
+  Default: `time`.
+- `--translateTime` (`-t`): Translate the epoch time value into a human-readable
+  date and time string. This flag also can set the format string to apply when
+  translating the date to a human-readable format. For a list of available pattern
+  letters, see the [`dateformat` documentation](https://www.npmjs.com/package/dateformat).
+  - The default format is `HH:MM:ss.l` in the local timezone.
+  - Require a `UTC:` prefix to translate time to UTC, e.g. `UTC:yyyy-mm-dd HH:MM:ss.l o`.
+  - Require a `SYS:` prefix to translate time to the local system's time zone. A
+    shortcut `SYS:standard` to translate time to `yyyy-mm-dd HH:MM:ss.l o` in
+    system time zone.
+- `--ignore` (`-i`): Ignore one or several keys, nested keys are supported with each property delimited by a dot character (`.`),
+  keys may be escaped to target property names that contains the delimiter itself:
+  (`-i time,hostname,req.headers,log\\.domain\\.corp/foo`).
+  The `--ignore` option would be ignored, if both `--ignore` and `--include` are passed.
+  Default: `hostname`.
+- `--include` (`-I`): The opposite of `--ignore`. Include one or several keys.
+- `--hideObject` (`-H`): Hide objects from output (but not error object)
+- `--singleLine` (`-S`): Print each log message on a single line (errors will still be multi-line)
+- `--config`: Specify a path to a config file containing the pino-pretty options.  pino-pretty will attempt to read from a `.pino-prettyrc` in your current directory (`process.cwd`) if not specified
+
+<a id="integration"></a>
+## Programmatic Integration
+
+We recommend against using `pino-pretty` in production and highly
+recommend installing `pino-pretty` as a development dependency.
+
+Install `pino-pretty` alongside `pino` and set the transport target to `'pino-pretty'`:
+
+```js
+const pino = require('pino')
+const logger = pino({
+  transport: {
+    target: 'pino-pretty'
+  },
+})
+
+logger.info('hi')
+```
+
+The transport option can also have an options object containing `pino-pretty` options:
+
+```js
+const pino = require('pino')
+const logger = pino({
+  transport: {
+    target: 'pino-pretty',
+    options: {
+      colorize: true
+    }
+  }
+})
+
+logger.info('hi')
+```
+
+Use it as a stream:
+
+```js
+const pino = require('pino')
+const pretty = require('pino-pretty')
+const logger = pino(pretty())
+
+logger.info('hi')
+```
+
+Options are also supported:
+
+```js
+const pino = require('pino')
+const pretty = require('pino-pretty')
+const stream = pretty({
+  colorize: true
+})
+const logger = pino(stream)
+
+logger.info('hi')
+```
+
+See the [Options](#options) section for all possible options.
+
+
+### Usage as a stream
+
+If you are using `pino-pretty` as a stream and you need to provide options to `pino`,
+pass the options as the first argument and `pino-pretty` as second argument:
+
+```js
+const pino = require('pino')
+const pretty = require('pino-pretty')
+const stream = pretty({
+  colorize: true
+})
+const logger = pino({ level: 'info' }, stream)
+
+// Nothing is printed
+logger.debug('hi')
+```
+
+### Usage with Jest
+
+Logging with Jest is _problematic_, as the test framework requires no asynchronous operation to
+continue after the test has finished. The following is the only supported way to use this module
+with Jest:
+
+```js
+import pino from 'pino'
+import pretty from 'pino-pretty'
+
+test('test pino-pretty', () => {
+  const logger = pino(pretty({ sync: true }));
+  logger.info('Info');
+  logger.error('Error');
+});
+```
+
+### Handling non-serializable options
+
+Using the new [pino v7+
+transports](https://getpino.io/#/docs/transports?id=v7-transports) not all
+options are serializable, for example if you want to use `messageFormat` as a
+function you will need to wrap `pino-pretty` in a custom module.
+
+Executing `main.js` below will log a colorized `hello world` message using a
+custom function `messageFormat`:
+
+```js
+// main.js
+const pino = require('pino')
+
+const logger = pino({
+  transport: {
+    target: './pino-pretty-transport',
+    options: {
+      colorize: true
+    }
+  },
+})
+
+logger.info('world')
+```
+
+```js
+// pino-pretty-transport.js
+module.exports = opts => require('pino-pretty')({
+  ...opts,
+  messageFormat: (log, messageKey) => `hello ${log[messageKey]}`
+})
+```
+
+<a id="options"></a>
+### Options
+
+The options accepted have keys corresponding to the options described in [CLI Arguments](#cliargs):
+
+```js
+{
+  colorize: colorette.isColorSupported, // --colorize
+  colorizeObjects: true, //--colorizeObjects
+  crlf: false, // --crlf
+  errorLikeObjectKeys: ['err', 'error'], // --errorLikeObjectKeys
+  errorProps: '', // --errorProps
+  levelFirst: false, // --levelFirst
+  messageKey: 'msg', // --messageKey
+  levelKey: 'level', // --levelKey
+  messageFormat: false, // --messageFormat
+  timestampKey: 'time', // --timestampKey
+  translateTime: false, // --translateTime
+  ignore: 'pid,hostname', // --ignore
+  include: 'level,time', // --include
+  hideObject: false, // --hideObject
+  singleLine: false, // --singleLine
+  customColors: 'err:red,info:blue', // --customColors
+  customLevels: 'err:99,info:1', // --customLevels
+  levelLabel: 'levelLabel', // --levelLabel
+  minimumLevel: 'info', // --minimumLevel
+  useOnlyCustomProps: true, // --useOnlyCustomProps
+  // The file or file descriptor (1 is stdout) to write to
+  destination: 1,
+
+  // Alternatively, pass a `sonic-boom` instance (allowing more flexibility):
+  // destination: new SonicBoom({ dest: 'a/file', mkdir: true })
+
+  // You can also configure some SonicBoom options directly
+  sync: false, // by default we write asynchronously
+  append: true, // the file is opened with the 'a' flag
+  mkdir: true, // create the target destination
+
+
+  customPrettifiers: {}
+}
+```
+
+The `colorize` default follows
+[`colorette.isColorSupported`](https://github.com/jorgebucaran/colorette#iscolorsupported).
+
+The defaults for `sync`, `append`, `mkdir` inherit from
+[`SonicBoom(opts)`](https://github.com/pinojs/sonic-boom#API).
+
+`customPrettifiers` option provides the ability to add a custom prettify function
+for specific log properties. `customPrettifiers` is an object, where keys are
+log properties that will be prettified and value is the prettify function itself.
+For example, if a log line contains a `query` property,
+you can specify a prettifier for it:
+
+```js
+{
+  customPrettifiers: {
+    query: prettifyQuery
+  }
+}
+//...
+const prettifyQuery = value => {
+  // do some prettify magic
+}
+```
+
+Additionally, `customPrettifiers` can be used to format the `time`, `hostname`,
+`pid`, `name`, `caller` and `level` outputs:
+
+```js
+{
+  customPrettifiers: {
+    // The argument for this function will be the same
+    // string that's at the start of the log-line by default:
+    time: timestamp => `🕰 ${timestamp}`,
+
+    // The argument for the level-prettifier may vary depending
+    // on if the levelKey option is used or not.
+    // By default this will be the same numerics as the Pino default:
+    level: logLevel => `LEVEL: ${logLevel}`,
+
+    // other prettifiers can be used for the other keys if needed, for example
+    hostname: hostname => colorGreen(hostname),
+    pid: pid => colorRed(pid),
+    name: name => colorBlue(name),
+    caller: caller => colorCyan(caller)
+  }
+}
+```
+
+Note that prettifiers do not include any coloring, if the stock coloring on
+`level` is desired, it can be accomplished using the following:
+
+```js
+const { colorizerFactory } = require('pino-pretty')
+const levelColorize = colorizerFactory(true)
+const levelPrettifier = logLevel => `LEVEL: ${levelColorize(logLevel)}`
+//...
+{
+  customPrettifiers: { level: levelPrettifier }
+}
+```
+
+`messageFormat` option allows you to customize the message output.
+A template `string` like this can define the format:
+
+```js
+{
+  messageFormat: '{levelLabel} - {pid} - url:{req.url}'
+}
+```
+
+In addition to this, if / end statement blocks can also be specified.
+Else statements and nested conditions are not supported.
+
+```js
+{
+  messageFormat: '{levelLabel} - {if pid}{pid} - {end}url:{req.url}'
+}
+```
+
+This option can also be defined as a `function` with this prototype:
+
+```js
+{
+  messageFormat: (log, messageKey, levelLabel) => {
+    // do some log message customization
+    return customized_message;
+  }
+}
+```
+
+## Limitations
+
+Because `pino-pretty` uses stdout redirection, in some cases the command may
+terminate with an error due to shell limitations.
+
+For example, currently, mingw64 based shells (e.g. Bash as supplied by [git for
+Windows](https://gitforwindows.org)) are affected and terminate the process with
+a `stdout is not a tty` error message.
+

+## Systemd example
+
+If you run your Node.js process via [Systemd](https://www.freedesktop.org/wiki/Software/systemd/) and you examine your logs with [journalctl](https://www.freedesktop.org/software/systemd/man/journalctl.html) some data will be duplicated. You can use a combination of `journalctl` options and `pino-pretty` options to shape the output.
+
+For example viewing the prettified logs of a process named `monitor` with `journalctl -u monitor -f | pino-pretty`, might output something like this:
+
+```
+Apr 24 07:40:01 nanopi node[6080]: {"level":30,"time":1587706801902,"pid":6080,"hostname":"nanopi","msg":"TT
+21","v":1}
+```
+As you can see, the timestamp, hostname, and pid are duplicated.
+If you just want the bare prettified Pino logs you can strip out the duplicate items from the `journalctl` output with the `-o cat` option of `journalctl`: 
+```
+journalctl -u monitor -f -o cat | pino-pretty
+```
+the output now looks something like this:
+```
+[1587706801902] INFO  (6080 on nanopi): TT 21
+```
+Make the output even more human readable by using the pino-pretty options `-t` to format the timestamp and `-i pid, hostname` to filter out hostname and pid:
+```
+[2020-04-24 05:42:24.836 +0000] INFO : TT 21
+```

+
+Write Pino transports easily.
+
+## Install
+
+```sh
+npm i pino-abstract-transport
+```
+
+## Usage
+
+```js
+import build from 'pino-abstract-transport'
+
+export default async function (opts) {
+  return build(async function (source) {
+    for await (let obj of source) {
+      console.log(obj)
+    }
+  })
+}
+```
+
+or in CommonJS and streams:
+
+```js
+'use strict'
+
+const build = require('pino-abstract-transport')
+
+module.exports = function (opts) {
+  return build(function (source) {
+    source.on('data', function (obj) {
+      console.log(obj)
+    })
+  })
+}
+```
+
+## Typescript usage
+
+Install the type definitions for node. Make sure the major version of the type definitions matches the node version you are using.
+
+#### Node 16
+
+```sh
+npm i -D @types/node@16
+```
+
+## API
+
+### build(fn, opts) => Stream
+
+Create a [`split2`](http://npm.im/split2) instance and returns it.
+This same instance is also passed to the given function, which is called
+synchronously.
+
+If `opts.transform` is `true`, `pino-abstract-transform` will 
+wrap the split2 instance and the returned stream using [`duplexify`](https://www.npmjs.com/package/duplexify),
+so they can be concatenated into multiple transports.
+
+#### Events emitted
+
+In addition to all events emitted by a [`Readable`](https://nodejs.org/api/stream.html#stream_class_stream_readable)
+stream, it emits the following events:
+
+* `unknown` where an unparsable line is found, both the line and optional error is emitted.
+
+#### Options
+
+* `parse` an option to change to data format passed to build function. When this option is set to `lines`,
+  the data is passed as a string, otherwise the data is passed as an object. Default: `undefined`.
+
+* `close(err, cb)` a function that is called to shutdown the transport. It's called both on error and non-error shutdowns.
+  It can also return a promise. In this case discard the the `cb` argument.
+
+* `parseLine(line)` a function that is used to parse line received from `pino`.
+
+* `expectPinoConfig` a boolean that indicates if the transport expects Pino to add some of its configuration to the stream. Default: `false`.
+
+## Example
+
+### custom parseLine
+
+You can allow custom `parseLine` from users while providing a simple and safe default parseLine.
+
+```js
+'use strict'
+
+const build = require('pino-abstract-transport')
+
+function defaultParseLine (line) {
+  const obj = JSON.parse(line)
+  // property foo will be added on each line
+  obj.foo = 'bar'
+  return obj
+}
+
+module.exports = function (opts) {
+  const parseLine = typeof opts.parseLine === 'function' ? opts.parseLine : defaultParseLine
+  return build(function (source) {
+    source.on('data', function (obj) {
+      console.log(obj)
+    })
+  }, {
+    parseLine: parseLine
+  })
+}
+```
+
+### Stream concatenation / pipeline
+
+You can pipeline multiple transports:
+
+```js
+const build = require('pino-abstract-transport')
+const { Transform, pipeline } = require('stream')
+
+function buildTransform () {
+  return build(function (source) {
+    return new Transform({
+      objectMode: true,
+      autoDestroy: true,
+      transform (line, enc, cb) {
+        line.service = 'bob'
+        cb(null, JSON.stringify(line))
+      }
+    })
+  }, { enablePipelining: true })
+}
+
+function buildDestination () {
+  return build(function (source) {
+    source.on('data', function (obj) {
+      console.log(obj)
+    })
+  })
+}
+
+pipeline(process.stdin, buildTransform(), buildDestination(), function (err) {
+  console.log('pipeline completed!', err)
+})
+```
+
+### Using pino config
+
+Setting `expectPinoConfig` to `true` will make the transport wait for pino to send its configuration before starting to process logs. It will add `levels`, `messageKey` and `errorKey` to the stream.
+
+When used with an incompatible version of pino, the stream will immediately error.
+
+```js
+import build from 'pino-abstract-transport'
+
+export default function (opts) {
+  return build(async function (source) {
+    for await (const obj of source) {
+      console.log(`[${source.levels.labels[obj.level]}]: ${obj[source.messageKey]}`)
+    }
+  }, {
+    expectPinoConfig: true
+  })
+}
+```

+[![NPM Package Version](https://img.shields.io/npm/v/sonic-boom)](https://www.npmjs.com/package/sonic-boom)
+[![Build Status](https://github.com/pinojs/sonic-boom/workflows/CI/badge.svg)](https://github.com/pinojs/sonic-boom/actions?query=workflow%3ACI)
+[![js-standard-style](https://img.shields.io/badge/code%20style-standard-brightgreen.svg?style=flat)](https://standardjs.com/)
+
+Extremely fast utf8-only stream implementation to write to files and
+file descriptors.
+
+This implementation is partial, but support backpressure and `.pipe()` in is here.
+However, it is 2-3x faster than Node Core `fs.createWriteStream()`:
+
+```
+benchSonic*1000: 1916.904ms
+benchSonicSync*1000: 8605.265ms
+benchSonic4k*1000: 1965.231ms
+benchSonicSync4k*1000: 1588.224ms
+benchCore*1000: 5851.959ms
+benchConsole*1000: 7605.713ms
+```
+
+Note that sync mode without buffering is _slower_ than a Node Core WritableStream, however
+this mode matches the expected behavior of `console.log()`.
+
+Note that if this is used to log to a windows terminal (`cmd.exe` or
+powershell), it is needed to run `chcp 65001` in the terminal to
+correctly display utf-8 characters, see
+[chcp](https://ss64.com/nt/chcp.html) for more details.
+
+## Install
+
+```
+npm i sonic-boom
+```
+
+## Example
+
+```js
+'use strict'
+
+const SonicBoom = require('sonic-boom')
+const sonic = new SonicBoom({ fd: process.stdout.fd }) // or { dest: '/path/to/destination' }
+
+for (let i = 0; i < 10; i++) {
+  sonic.write('hello sonic\n')
+}
+```
+
+## API
+
+### SonicBoom(opts)
+
+Creates a new instance of SonicBoom.
+
+The options are:
+
+* `fd`: a file descriptor, something that is returned by `fs.open` or
+   `fs.openSync`.
+* `dest`: a string that is a path to a file to be written to (mode controlled by the `append` option).
+* `minLength`: the minimum length of the internal buffer that is
+  required to be full before flushing.
+* `maxLength`: the maximum length of the internal buffer. If a write operation would cause the buffer
+  to exceed `maxLength`, the data written is dropped and a `drop` event is emitted with the dropped data
+* `maxWrite`: the maximum number of bytes that can be written; default: 16384
+* `sync`: perform writes synchronously (similar to `console.log`).
+* `fsync`: perform a [fsyncSync](https://nodejs.org/api/fs.html#fsfsyncsyncfd) every time a write is completed.
+* `append`: appends writes to dest file instead of truncating it (default `true`).
+* `mode`: specify the creating file `mode` (see [fs.open()](https://nodejs.org/api/fs.html#fsopenpath-flags-mode-callback) from Node.js core).
+* `mkdir`: ensure directory for dest file exists when `true` (default `false`).
+* `retryEAGAIN(err, writeBufferLen, remainingBufferLen)`: a function that will be called when sonic-boom
+    write/writeSync/flushSync encounters a EAGAIN or EBUSY error. If the return value is
+    true sonic-boom will retry the operation, otherwise it will bubble the
+    error. `err` is the error that caused this function to be called,
+    `writeBufferLen` is the length of the buffer sonic-boom tried to write, and
+    `remainingBufferLen` is the length of the remaining buffer sonic-boom didn't try to write.
+
+For `sync:false`  a `SonicBoom` instance will emit the `'ready'` event when a file descriptor is available.
+For `sync:true` this is not relevant because the `'ready'` event will be fired when the `SonicBoom` instance is created, before it can be subscribed to.
+
+
+### SonicBoom#write(string)
+
+Writes the string to the file.
+It will return false to signal the producer to slow down.
+
+### SonicBoom#flush([cb])
+
+Writes the current buffer to the file if a write was not in progress.
+Do nothing if `minLength` is zero or if it is already writing.
+
+call the callback when the flush operation is completed. when failed the callback is called with an error.
+
+### SonicBoom#reopen([file])
+
+Reopen the file in place, useful for log rotation.
+
+Example:
+
+```js
+const stream = new SonicBoom('./my.log')
+process.on('SIGUSR2', function () {
+  stream.reopen()
+})
+```
+
+### SonicBoom#flushSync()
+
+Flushes the buffered data synchronously. This is a costly operation.
+
+### SonicBoom#end()
+
+Closes the stream, the data will be flushed down asynchronously
+
+### SonicBoom#destroy()
+
+Closes the stream immediately, the data is not flushed.
+
+### Events
+
+
+#### SonicBoom#close
+
+See [Stream#close](https://nodejs.org/api/stream.html#event-close). The `'close'` event when the instance has been closed.
+
+#### SonicBoom#drain
+
+See [Stream#drain](https://nodejs.org/api/stream.html#event-drain). The `'drain'` event is emitted when source can resume sending data.
+
+#### SonicBoom#drop <any>
+
+When destination file maximal length is reached, the `'drop'` event is emitted with data that could not be written. 
+
+#### SonicBoom#error <Error>
+
+The `'error'` event is emitted when the destination file can not be opened, or written.
+
+#### SonicBoom#finish
+
+See [Stream#finish](https://nodejs.org/api/stream.html#event-finish). The `'finish'` event after calling `end()` method and when all data was written.
+
+#### SonicBoom#ready
+
+The `'ready'` event occurs when the created instance is ready to process input.
+
+#### SonicBoom#write <number>
+
+The `'write'` event occurs every time data is written to the underlying file. It emits the number of written bytes.
