# jest-changed-files
A module used internally by Jest to check which files have changed since you last committed in git or hg.
## Install
```sh
$ npm install --save jest-changed-files
```
## API
### `getChangedFilesForRoots(roots: <Array<string>>, options: ?object): Promise<?object>`
Get the list of files and repos that have changed since the last commit.
#### Parameters
roots: Array of string paths gathered from [jest roots](https://jestjs.io/docs/configuration.html#roots-array-string).
options: Object literal with keys
- lastCommit: boolean
- withAncestor: boolean
### findRepos(roots: <Array<string>>): Promise<?object>
Get a set of git and hg repositories.
#### Parameters
roots: Array of string paths gathered from [jest roots](https://jestjs.io/docs/configuration.html#roots-array-string).
## Usage
```javascript
import {getChangedFilesForRoots} from 'jest-changed-files';
getChangedFilesForRoots(['/path/to/test'], {
lastCommit: true,
withAncestor: true,
}).then(files => {
/*
{
repos: [],
changedFiles: []
}
*/
});
```
```javascript
import {findRepos} from 'jest-changed-files';
findRepos(['/path/to/test']).then(repos => {
/*
{
git: Set<Path>,
hg: Set<Path>
}
*/
});
```

## Highlights
- Expressive API
- Highly performant
- Ability to nest styles
- [256/Truecolor color support](#256-and-truecolor-color-support)
- Auto-detects color support
- Doesn't extend `String.prototype`
- Clean and focused
- Actively maintained
- [Used by ~50,000 packages](https://www.npmjs.com/browse/depended/chalk) as of January 1, 2020
## Install
```console
$ npm install chalk
```
## Usage
```js
const chalk = require('chalk');
console.log(chalk.blue('Hello world!'));
```
Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
```js
const chalk = require('chalk');
const log = console.log;
// Combine styled and normal strings
log(chalk.blue('Hello') + ' World' + chalk.red('!'));
// Compose multiple styles using the chainable API
log(chalk.blue.bgRed.bold('Hello world!'));
// Pass in multiple arguments
log(chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz'));
// Nest styles
log(chalk.red('Hello', chalk.underline.bgBlue('world') + '!'));
// Nest styles of the same type even (color, underline, background)
log(chalk.green(
'I am a green line ' +
chalk.blue.underline.bold('with a blue substring') +
' that becomes green again!'
));
// ES2015 template literal
log(`
CPU: ${chalk.red('90%')}
RAM: ${chalk.green('40%')}
DISK: ${chalk.yellow('70%')}
`);
// ES2015 tagged template literal
log(chalk`
CPU: {red ${cpu.totalPercent}%}
RAM: {green ${ram.used / ram.total * 100}%}
DISK: {rgb(255,131,0) ${disk.used / disk.total * 100}%}
`);
// Use RGB colors in terminal emulators that support it.
log(chalk.keyword('orange')('Yay for orange colored text!'));
log(chalk.rgb(123, 45, 67).underline('Underlined reddish color'));
log(chalk.hex('#DEADED').bold('Bold gray!'));
```
Easily define your own themes:
```js
const chalk = require('chalk');
const error = chalk.bold.red;
const warning = chalk.keyword('orange');
console.log(error('Error!'));
console.log(warning('Warning!'));
```
Take advantage of console.log [string substitution](https://nodejs.org/docs/latest/api/console.html#console_console_log_data_args):
```js
const name = 'Sindre';
console.log(chalk.green('Hello %s'), name);
//=> 'Hello Sindre'
```
## API
### chalk.`<style>[.<style>...](string, [string...])`
Example: `chalk.red.bold.underline('Hello', 'world');`
Chain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter, and later styles take precedent in case of a conflict. This simply means that `chalk.red.yellow.green` is equivalent to `chalk.green`.
Multiple arguments will be separated by space.
### chalk.level
Specifies the level of color support.
Color support is automatically detected, but you can override it by setting the `level` property. You should however only do this in your own code as it applies globally to all Chalk consumers.
If you need to change this in a reusable module, create a new instance:
```js
const ctx = new chalk.Instance({level: 0});
```
| Level | Description |
| :---: | :--- |
| `0` | All colors disabled |
| `1` | Basic color support (16 colors) |
| `2` | 256 color support |
| `3` | Truecolor support (16 million colors) |
### chalk.supportsColor
Detect whether the terminal [supports color](https://github.com/chalk/supports-color). Used internally and handled for you, but exposed for convenience.
Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, use the environment variable `FORCE_COLOR=1` (level 1), `FORCE_COLOR=2` (level 2), or `FORCE_COLOR=3` (level 3) to forcefully enable color, or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.
### chalk.stderr and chalk.stderr.supportsColor
`chalk.stderr` contains a separate instance configured with color support detected for `stderr` stream instead of `stdout`. Override rules from `chalk.supportsColor` apply to this too. `chalk.stderr.supportsColor` is exposed for convenience.
## Styles
### Modifiers
- `reset` - Resets the current color chain.
- `bold` - Make text bold.
- `dim` - Emitting only a small amount of light.
- `italic` - Make text italic. *(Not widely supported)*
- `underline` - Make text underline. *(Not widely supported)*
- `inverse`- Inverse background and foreground colors.
- `hidden` - Prints the text, but makes it invisible.
- `strikethrough` - Puts a horizontal line through the center of the text. *(Not widely supported)*
- `visible`- Prints the text only when Chalk has a color level > 0. Can be useful for things that are purely cosmetic.
### Colors
- `black`
- `red`
- `green`
- `yellow`
- `blue`
- `magenta`
- `cyan`
- `white`
- `blackBright` (alias: `gray`, `grey`)
- `redBright`
- `greenBright`
- `yellowBright`
- `blueBright`
- `magentaBright`
- `cyanBright`
- `whiteBright`
### Background colors
- `bgBlack`
- `bgRed`
- `bgGreen`
- `bgYellow`
- `bgBlue`
- `bgMagenta`
- `bgCyan`
- `bgWhite`
- `bgBlackBright` (alias: `bgGray`, `bgGrey`)
- `bgRedBright`
- `bgGreenBright`
- `bgYellowBright`
- `bgBlueBright`
- `bgMagentaBright`
- `bgCyanBright`
- `bgWhiteBright`
## Tagged template literal
Chalk can be used as a [tagged template literal](https://exploringjs.com/es6/ch_template-literals.html#_tagged-template-literals).
```js
const chalk = require('chalk');
const miles = 18;
const calculateFeet = miles => miles * 5280;
console.log(chalk`
There are {bold 5280 feet} in a mile.
In {bold ${miles} miles}, there are {green.bold ${calculateFeet(miles)} feet}.
`);
```
Blocks are delimited by an opening curly brace (`{`), a style, some content, and a closing curly brace (`}`).
Template styles are chained exactly like normal Chalk styles. The following three statements are equivalent:
```js
console.log(chalk.bold.rgb(10, 100, 200)('Hello!'));
console.log(chalk.bold.rgb(10, 100, 200)`Hello!`);
console.log(chalk`{bold.rgb(10,100,200) Hello!}`);
```
Note that function styles (`rgb()`, `hsl()`, `keyword()`, etc.) may not contain spaces between parameters.
All interpolated values (`` chalk`${foo}` ``) are converted to strings via the `.toString()` method. All curly braces (`{` and `}`) in interpolated value strings are escaped.
## 256 and Truecolor color support
Chalk supports 256 colors and [Truecolor](https://gist.github.com/XVilka/8346728) (16 million colors) on supported terminal apps.
Colors are downsampled from 16 million RGB values to an ANSI color format that is supported by the terminal emulator (or by specifying `{level: n}` as a Chalk option). For example, Chalk configured to run at level 1 (basic color support) will downsample an RGB value of #FF0000 (red) to 31 (ANSI escape for red).
Examples:
- `chalk.hex('#DEADED').underline('Hello, world!')`
- `chalk.keyword('orange')('Some orange text')`
- `chalk.rgb(15, 100, 204).inverse('Hello!')`
Background versions of these models are prefixed with `bg` and the first level of the module capitalized (e.g. `keyword` for foreground colors and `bgKeyword` for background colors).
- `chalk.bgHex('#DEADED').underline('Hello, world!')`
- `chalk.bgKeyword('orange')('Some orange text')`
- `chalk.bgRgb(15, 100, 204).inverse('Hello!')`
The following color models can be used:
- [`rgb`](https://en.wikipedia.org/wiki/RGB_color_model) - Example: `chalk.rgb(255, 136, 0).bold('Orange!')`
- [`hex`](https://en.wikipedia.org/wiki/Web_colors#Hex_triplet) - Example: `chalk.hex('#FF8800').bold('Orange!')`
- [`keyword`](https://www.w3.org/wiki/CSS/Properties/color/keywords) (CSS keywords) - Example: `chalk.keyword('orange').bold('Orange!')`
- [`hsl`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsl(32, 100, 50).bold('Orange!')`
- [`hsv`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsv(32, 100, 100).bold('Orange!')`
- [`hwb`](https://en.wikipedia.org/wiki/HWB_color_model) - Example: `chalk.hwb(32, 0, 50).bold('Orange!')`
- [`ansi`](https://en.wikipedia.org/wiki/ANSI_escape_code#3/4_bit) - Example: `chalk.ansi(31).bgAnsi(93)('red on yellowBright')`
- [`ansi256`](https://en.wikipedia.org/wiki/ANSI_escape_code#8-bit) - Example: `chalk.bgAnsi256(194)('Honeydew, more or less')`
## Windows
If you're on Windows, do yourself a favor and use [Windows Terminal](https://github.com/microsoft/terminal) instead of `cmd.exe`.
## Origin story
[colors.js](https://github.com/Marak/colors.js) used to be the most popular string styling module, but it has serious deficiencies like extending `String.prototype` which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68) and the package is unmaintained. Although there are other packages, they either do too much or not enough. Chalk is a clean and focused alternative.
## chalk for enterprise
Available as part of the Tidelift Subscription.
The maintainers of chalk and thousands of other packages are working with Tidelift to deliver commercial support and maintenance for the open source dependencies you use to build your applications.

A cross platform solution to node's spawn and spawnSync.
## Installation
Node.js version 8 and up:
`$ npm install cross-spawn`
Node.js version 7 and under:
`$ npm install cross-spawn@6`
## Why
Node has issues when using spawn on Windows:
- It ignores [PATHEXT](https://github.com/joyent/node/issues/2318)
- It does not support [shebangs](https://en.wikipedia.org/wiki/Shebang_(Unix))
- Has problems running commands with [spaces](https://github.com/nodejs/node/issues/7367)
- Has problems running commands with posix relative paths (e.g.: `./my-folder/my-executable`)
- Has an [issue](https://github.com/moxystudio/node-cross-spawn/issues/82) with command shims (files in `node_modules/.bin/`), where arguments with quotes and parenthesis would result in [invalid syntax error](https://github.com/moxystudio/node-cross-spawn/blob/e77b8f22a416db46b6196767bcd35601d7e11d54/test/index.test.js#L149)
- No `options.shell` support on node `<v4.8`
All these issues are handled correctly by `cross-spawn`.
There are some known modules, such as [win-spawn](https://github.com/ForbesLindesay/win-spawn), that try to solve this but they are either broken or provide faulty escaping of shell arguments.
## Usage
Exactly the same way as node's [`spawn`](https://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options) or [`spawnSync`](https://nodejs.org/api/child_process.html#child_process_child_process_spawnsync_command_args_options), so it's a drop in replacement.
```js
const spawn = require('cross-spawn');
// Spawn NPM asynchronously
const child = spawn('npm', ['list', '-g', '-depth', '0'], { stdio: 'inherit' });
// Spawn NPM synchronously
const result = spawn.sync('npm', ['list', '-g', '-depth', '0'], { stdio: 'inherit' });
```
## Caveats
### Using `options.shell` as an alternative to `cross-spawn`
Starting from node `v4.8`, `spawn` has a `shell` option that allows you run commands from within a shell. This new option solves
the [PATHEXT](https://github.com/joyent/node/issues/2318) issue but:
- It's not supported in node `<v4.8`
- You must manually escape the command and arguments which is very error prone, specially when passing user input
- There are a lot of other unresolved issues from the [Why](#why) section that you must take into account
If you are using the `shell` option to spawn a command in a cross platform way, consider using `cross-spawn` instead. You have been warned.
### `options.shell` support
While `cross-spawn` adds support for `options.shell` in node `<v4.8`, all of its enhancements are disabled.
This mimics the Node.js behavior. More specifically, the command and its arguments will not be automatically escaped nor shebang support will be offered. This is by design because if you are using `options.shell` you are probably targeting a specific platform anyway and you don't want things to get into your way.
### Shebangs support
While `cross-spawn` handles shebangs on Windows, its support is limited. More specifically, it just supports `#!/usr/bin/env <program>` where `<program>` must not contain any arguments.
If you would like to have the shebang support improved, feel free to contribute via a pull-request.
Remember to always test your code on Windows!

`$ npm test`
`$ npm test -- --watch` during development

[![Build Status](https://travis-ci.com/sindresorhus/execa.svg?branch=master)](https://travis-ci.com/github/sindresorhus/execa) [![Coverage Status](https://coveralls.io/repos/github/sindresorhus/execa/badge.svg?branch=master)](https://coveralls.io/github/sindresorhus/execa?branch=master)
> Process execution for humans
## Why
This package improves [`child_process`](https://nodejs.org/api/child_process.html) methods with:
- Promise interface.
- [Strips the final newline](#stripfinalnewline) from the output so you don't have to do `stdout.trim()`.
- Supports [shebang](https://en.wikipedia.org/wiki/Shebang_(Unix)) binaries cross-platform.
- [Improved Windows support.](https://github.com/IndigoUnited/node-cross-spawn#why)
- Higher max buffer. 100 MB instead of 200 KB.
- [Executes locally installed binaries by name.](#preferlocal)
- [Cleans up spawned processes when the parent process dies.](#cleanup)
- [Get interleaved output](#all) from `stdout` and `stderr` similar to what is printed on the terminal. [*(Async only)*](#execasyncfile-arguments-options)
- [Can specify file and arguments as a single string without a shell](#execacommandcommand-options)
- More descriptive errors.
## Install
```
$ npm install execa
```
## Usage
```js
const execa = require('execa');
(async () => {
const {stdout} = await execa('echo', ['unicorns']);
console.log(stdout);
//=> 'unicorns'
})();
```
### Pipe the child process stdout to the parent
```js
const execa = require('execa');
execa('echo', ['unicorns']).stdout.pipe(process.stdout);
```
### Handling Errors
```js
const execa = require('execa');
(async () => {
// Catching an error
try {
await execa('unknown', ['command']);
} catch (error) {
console.log(error);
/*
{
message: 'Command failed with ENOENT: unknown command spawn unknown ENOENT',
errno: -2,
code: 'ENOENT',
syscall: 'spawn unknown',
path: 'unknown',
spawnargs: ['command'],
originalMessage: 'spawn unknown ENOENT',
shortMessage: 'Command failed with ENOENT: unknown command spawn unknown ENOENT',
command: 'unknown command',
stdout: '',
stderr: '',
all: '',
failed: true,
timedOut: false,
isCanceled: false,
killed: false
}
*/
}
})();
```
### Cancelling a spawned process
```js
const execa = require('execa');
(async () => {
const subprocess = execa('node');
setTimeout(() => {
subprocess.cancel();
}, 1000);
try {
await subprocess;
} catch (error) {
console.log(subprocess.killed); // true
console.log(error.isCanceled); // true
}
})()
```
### Catching an error with the sync method
```js
try {
execa.sync('unknown', ['command']);
} catch (error) {
console.log(error);
/*
{
message: 'Command failed with ENOENT: unknown command spawnSync unknown ENOENT',
errno: -2,
code: 'ENOENT',
syscall: 'spawnSync unknown',
path: 'unknown',
spawnargs: ['command'],
originalMessage: 'spawnSync unknown ENOENT',
shortMessage: 'Command failed with ENOENT: unknown command spawnSync unknown ENOENT',
command: 'unknown command',
stdout: '',
stderr: '',
all: '',
failed: true,
timedOut: false,
isCanceled: false,
killed: false
}
*/
}
```
### Kill a process
Using SIGTERM, and after 2 seconds, kill it with SIGKILL.
```js
const subprocess = execa('node');
setTimeout(() => {
subprocess.kill('SIGTERM', {
forceKillAfterTimeout: 2000
});
}, 1000);
```
## API
### execa(file, arguments, options?)
Execute a file. Think of this as a mix of [`child_process.execFile()`](https://nodejs.org/api/child_process.html#child_process_child_process_execfile_file_args_options_callback) and [`child_process.spawn()`](https://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options).
No escaping/quoting is needed.
Unless the [`shell`](#shell) option is used, no shell interpreter (Bash, `cmd.exe`, etc.) is used, so shell features such as variables substitution (`echo $PATH`) are not allowed.
Returns a [`child_process` instance](https://nodejs.org/api/child_process.html#child_process_class_childprocess) which:
- is also a `Promise` resolving or rejecting with a [`childProcessResult`](#childProcessResult).
- exposes the following additional methods and properties.
#### kill(signal?, options?)
Same as the original [`child_process#kill()`](https://nodejs.org/api/child_process.html#child_process_subprocess_kill_signal) except: if `signal` is `SIGTERM` (the default value) and the child process is not terminated after 5 seconds, force it by sending `SIGKILL`.
##### options.forceKillAfterTimeout
Type: `number | false`\
Default: `5000`
Milliseconds to wait for the child process to terminate before sending `SIGKILL`.
Can be disabled with `false`.
#### cancel()
Similar to [`childProcess.kill()`](https://nodejs.org/api/child_process.html#child_process_subprocess_kill_signal). This is preferred when cancelling the child process execution as the error is more descriptive and [`childProcessResult.isCanceled`](#iscanceled) is set to `true`.
#### all
Type: `ReadableStream | undefined`
Stream combining/interleaving [`stdout`](https://nodejs.org/api/child_process.html#child_process_subprocess_stdout) and [`stderr`](https://nodejs.org/api/child_process.html#child_process_subprocess_stderr).
This is `undefined` if either:
- the [`all` option](#all-2) is `false` (the default value)
- both [`stdout`](#stdout-1) and [`stderr`](#stderr-1) options are set to [`'inherit'`, `'ipc'`, `Stream` or `integer`](https://nodejs.org/dist/latest-v6.x/docs/api/child_process.html#child_process_options_stdio)
### execa.sync(file, arguments?, options?)
Execute a file synchronously.
Returns or throws a [`childProcessResult`](#childProcessResult).
### execa.command(command, options?)
Same as [`execa()`](#execafile-arguments-options) except both file and arguments are specified in a single `command` string. For example, `execa('echo', ['unicorns'])` is the same as `execa.command('echo unicorns')`.
If the file or an argument contains spaces, they must be escaped with backslashes. This matters especially if `command` is not a constant but a variable, for example with `__dirname` or `process.cwd()`. Except for spaces, no escaping/quoting is needed.
The [`shell` option](#shell) must be used if the `command` uses shell-specific features, as opposed to being a simple `file` followed by its `arguments`.
### execa.commandSync(command, options?)
Same as [`execa.command()`](#execacommand-command-options) but synchronous.
Returns or throws a [`childProcessResult`](#childProcessResult).
### execa.node(scriptPath, arguments?, options?)
Execute a Node.js script as a child process.
Same as `execa('node', [scriptPath, ...arguments], options)` except (like [`child_process#fork()`](https://nodejs.org/api/child_process.html#child_process_child_process_fork_modulepath_args_options)):
- the current Node version and options are used. This can be overridden using the [`nodePath`](#nodepath-for-node-only) and [`nodeOptions`](#nodeoptions-for-node-only) options.
- the [`shell`](#shell) option cannot be used
- an extra channel [`ipc`](https://nodejs.org/api/child_process.html#child_process_options_stdio) is passed to [`stdio`](#stdio)
### childProcessResult
Type: `object`
Result of a child process execution. On success this is a plain object. On failure this is also an `Error` instance.
The child process [fails](#failed) when:
- its [exit code](#exitcode) is not `0`
- it was [killed](#killed) with a [signal](#signal)
- [timing out](#timedout)
- [being canceled](#iscanceled)
- there's not enough memory or there are already too many child processes
#### command
Type: `string`
The file and arguments that were run.
#### exitCode
Type: `number`
The numeric exit code of the process that was run.
#### stdout
Type: `string | Buffer`
The output of the process on stdout.
#### stderr
Type: `string | Buffer`
The output of the process on stderr.
#### all
Type: `string | Buffer | undefined`
The output of the process with `stdout` and `stderr` interleaved.
This is `undefined` if either:
- the [`all` option](#all-2) is `false` (the default value)
- `execa.sync()` was used
#### failed
Type: `boolean`
Whether the process failed to run.
#### timedOut
Type: `boolean`
Whether the process timed out.
#### isCanceled
Type: `boolean`
Whether the process was canceled.
#### killed
Type: `boolean`
Whether the process was killed.
#### signal
Type: `string | undefined`
The name of the signal that was used to terminate the process. For example, `SIGFPE`.
If a signal terminated the process, this property is defined and included in the error message. Otherwise it is `undefined`.
#### signalDescription
Type: `string | undefined`
A human-friendly description of the signal that was used to terminate the process. For example, `Floating point arithmetic error`.
If a signal terminated the process, this property is defined and included in the error message. Otherwise it is `undefined`. It is also `undefined` when the signal is very uncommon which should seldomly happen.
#### message
Type: `string`
Error message when the child process failed to run. In addition to the [underlying error message](#originalMessage), it also contains some information related to why the child process errored.
The child process [stderr](#stderr) then [stdout](#stdout) are appended to the end, separated with newlines and not interleaved.
#### shortMessage
Type: `string`
This is the same as the [`message` property](#message) except it does not include the child process stdout/stderr.
#### originalMessage
Type: `string | undefined`
Original error message. This is the same as the `message` property except it includes neither the child process stdout/stderr nor some additional information added by Execa.
This is `undefined` unless the child process exited due to an `error` event or a timeout.
### options
Type: `object`
#### cleanup
Type: `boolean`\
Default: `true`
Kill the spawned process when the parent process exits unless either:
- the spawned process is [`detached`](https://nodejs.org/api/child_process.html#child_process_options_detached)
- the parent process is terminated abruptly, for example, with `SIGKILL` as opposed to `SIGTERM` or a normal exit
#### preferLocal
Type: `boolean`\
Default: `false`
Prefer locally installed binaries when looking for a binary to execute.\
If you `$ npm install foo`, you can then `execa('foo')`.
#### localDir
Type: `string`\
Default: `process.cwd()`
Preferred path to find locally installed binaries in (use with `preferLocal`).
#### execPath
Type: `string`\
Default: `process.execPath` (Current Node.js executable)
Path to the Node.js executable to use in child processes.
This can be either an absolute path or a path relative to the [`cwd` option](#cwd).
Requires [`preferLocal`](#preferlocal) to be `true`.
For example, this can be used together with [`get-node`](https://github.com/ehmicky/get-node) to run a specific Node.js version in a child process.
#### buffer
Type: `boolean`\
Default: `true`
Buffer the output from the spawned process. When set to `false`, you must read the output of [`stdout`](#stdout-1) and [`stderr`](#stderr-1) (or [`all`](#all) if the [`all`](#all-2) option is `true`). Otherwise the returned promise will not be resolved/rejected.
If the spawned process fails, [`error.stdout`](#stdout), [`error.stderr`](#stderr), and [`error.all`](#all) will contain the buffered data.
#### input
Type: `string | Buffer | stream.Readable`
Write some input to the `stdin` of your binary.\
Streams are not allowed when using the synchronous methods.
#### stdin
Type: `string | number | Stream | undefined`\
Default: `pipe`
Same options as [`stdio`](https://nodejs.org/dist/latest-v6.x/docs/api/child_process.html#child_process_options_stdio).
#### stdout
Type: `string | number | Stream | undefined`\
Default: `pipe`
Same options as [`stdio`](https://nodejs.org/dist/latest-v6.x/docs/api/child_process.html#child_process_options_stdio).
#### stderr
Type: `string | number | Stream | undefined`\
Default: `pipe`
Same options as [`stdio`](https://nodejs.org/dist/latest-v6.x/docs/api/child_process.html#child_process_options_stdio).
#### all
Type: `boolean`\
Default: `false`
Add an `.all` property on the [promise](#all) and the [resolved value](#all-1). The property contains the output of the process with `stdout` and `stderr` interleaved.
#### reject
Type: `boolean`\
Default: `true`
Setting this to `false` resolves the promise with the error instead of rejecting it.
#### stripFinalNewline
Type: `boolean`\
Default: `true`
Strip the final [newline character](https://en.wikipedia.org/wiki/Newline) from the output.
#### extendEnv
Type: `boolean`\
Default: `true`
Set to `false` if you don't want to extend the environment variables when providing the `env` property.
---
Execa also accepts the below options which are the same as the options for [`child_process#spawn()`](https://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options)/[`child_process#exec()`](https://nodejs.org/api/child_process.html#child_process_child_process_exec_command_options_callback)
#### cwd
Type: `string`\
Default: `process.cwd()`
Current working directory of the child process.
#### env
Type: `object`\
Default: `process.env`
Environment key-value pairs. Extends automatically from `process.env`. Set [`extendEnv`](#extendenv) to `false` if you don't want this.
#### argv0
Type: `string`
Explicitly set the value of `argv[0]` sent to the child process. This will be set to `file` if not specified.
#### stdio
Type: `string | string[]`\
Default: `pipe`
Child's [stdio](https://nodejs.org/api/child_process.html#child_process_options_stdio) configuration.
#### serialization
Type: `string`\
Default: `'json'`
Specify the kind of serialization used for sending messages between processes when using the [`stdio: 'ipc'`](#stdio) option or [`execa.node()`](#execanodescriptpath-arguments-options):
- `json`: Uses `JSON.stringify()` and `JSON.parse()`.
- `advanced`: Uses [`v8.serialize()`](https://nodejs.org/api/v8.html#v8_v8_serialize_value)
Requires Node.js `13.2.0` or later.
[More info.](https://nodejs.org/api/child_process.html#child_process_advanced_serialization)
#### detached
Type: `boolean`
Prepare child to run independently of its parent process. Specific behavior [depends on the platform](https://nodejs.org/api/child_process.html#child_process_options_detached).
#### uid
Type: `number`
Sets the user identity of the process.
#### gid
Type: `number`
Sets the group identity of the process.
#### shell
Type: `boolean | string`\
Default: `false`
If `true`, runs `file` inside of a shell. Uses `/bin/sh` on UNIX and `cmd.exe` on Windows. A different shell can be specified as a string. The shell should understand the `-c` switch on UNIX or `/d /s /c` on Windows.
We recommend against using this option since it is:
- not cross-platform, encouraging shell-specific syntax.
- slower, because of the additional shell interpretation.
- unsafe, potentially allowing command injection.
#### encoding
Type: `string | null`\
Default: `utf8`
Specify the character encoding used to decode the `stdout` and `stderr` output. If set to `null`, then `stdout` and `stderr` will be a `Buffer` instead of a string.
#### timeout
Type: `number`\
Default: `0`
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.
#### maxBuffer
Type: `number`\
Default: `100_000_000` (100 MB)
Largest amount of data in bytes allowed on `stdout` or `stderr`.
#### killSignal
Type: `string | number`\
Default: `SIGTERM`
Signal value to be used when the spawned process will be killed.
#### windowsVerbatimArguments
Type: `boolean`\
Default: `false`
If `true`, no quoting or escaping of arguments is done on Windows. Ignored on other platforms. This is set to `true` automatically when the `shell` option is `true`.
#### windowsHide
Type: `boolean`\
Default: `true`
On Windows, do not create a new console window. Please note this also prevents `CTRL-C` [from working](https://github.com/nodejs/node/issues/29837) on Windows.
#### nodePath *(For `.node()` only)*
Type: `string`\
Default: [`process.execPath`](https://nodejs.org/api/process.html#process_process_execpath)
Node.js executable used to create the child process.
#### nodeOptions *(For `.node()` only)*
Type: `string[]`\
Default: [`process.execArgv`](https://nodejs.org/api/process.html#process_process_execargv)
List of [CLI options](https://nodejs.org/api/cli.html#cli_options) passed to the Node.js executable.
## Tips
### Retry on error
Gracefully handle failures by using automatic retries and exponential backoff with the [`p-retry`](https://github.com/sindresorhus/p-retry) package:
```js
const pRetry = require('p-retry');
const run = async () => {
const results = await execa('curl', ['-sSL', 'https://sindresorhus.com/unicorn']);
return results;
};
(async () => {
console.log(await pRetry(run, {retries: 5}));
})();
```
### Save and pipe output from a child process
Let's say you want to show the output of a child process in real-time while also saving it to a variable.
```js
const execa = require('execa');
const subprocess = execa('echo', ['foo']);
subprocess.stdout.pipe(process.stdout);
(async () => {
const {stdout} = await subprocess;
console.log('child output:', stdout);
})();
```
### Redirect output to a file
```js
const execa = require('execa');
const subprocess = execa('echo', ['foo'])
subprocess.stdout.pipe(fs.createWriteStream('stdout.txt'))
```
### Redirect input from a file
```js
const execa = require('execa');
const subprocess = execa('cat')
fs.createReadStream('stdin.txt').pipe(subprocess.stdin)
```
### Execute the current package's binary
```js
const {getBinPathSync} = require('get-bin-path');
const binPath = getBinPathSync();
const subprocess = execa(binPath);
```
`execa` can be combined with [`get-bin-path`](https://github.com/ehmicky/get-bin-path) to test the current package's binary. As opposed to hard-coding the path to the binary, this validates that the `package.json` `bin` field is correctly set up.

## API
The methods returns a promise that resolves when the `end` event fires on the stream, indicating that there is no more data to be read. The stream is switched to flowing mode.
### getStream(stream, options?)
Get the `stream` as a string.
#### options
Type: `object`
##### encoding
Type: `string`\
Default: `'utf8'`
[Encoding](https://nodejs.org/api/buffer.html#buffer_buffer) of the incoming stream.
##### maxBuffer
Type: `number`\
Default: `Infinity`
Maximum length of the returned string. If it exceeds this value before the stream ends, the promise will be rejected with a `getStream.MaxBufferError` error.
### getStream.buffer(stream, options?)
Get the `stream` as a buffer.
It honors the `maxBuffer` option as above, but it refers to byte length rather than string length.
### getStream.array(stream, options?)
Get the `stream` as an array of values.
It honors both the `maxBuffer` and `encoding` options. The behavior changes slightly based on the encoding chosen:
- When `encoding` is unset, it assumes an [object mode stream](https://nodesource.com/blog/understanding-object-streams/) and collects values emitted from `stream` unmodified. In this case `maxBuffer` refers to the number of items in the array (not the sum of their sizes).
- When `encoding` is set to `buffer`, it collects an array of buffers. `maxBuffer` refers to the summed byte lengths of every buffer in the array.
- When `encoding` is set to anything else, it collects an array of strings. `maxBuffer` refers to the summed character lengths of every string in the array.
## Errors
If the input stream emits an `error` event, the promise will be rejected with the error. The buffered data will be attached to the `bufferedData` property of the error.
```js
(async () => {
try {
await getStream(streamThatErrorsAtTheEnd('unicorn'));
} catch (error) {
console.log(error.bufferedData);
//=> 'unicorn'
}
})()
```
## FAQ
### How is this different from [`concat-stream`](https://github.com/maxogden/concat-stream)?
This module accepts a stream instead of being one and returns a promise instead of using a callback. The API is simpler and it only supports returning a string, buffer, or array. It doesn't have a fragile type inference. You explicitly choose what you want. And it doesn't depend on the huge `readable-stream` package.

> Get your [PATH](https://en.wikipedia.org/wiki/PATH_(variable)) prepended with locally installed binaries
In [npm run scripts](https://docs.npmjs.com/cli/run-script) you can execute locally installed binaries by name. This enables the same outside npm.
## Install
```
$ npm install npm-run-path
```
## Usage
```js
const childProcess = require('child_process');
const npmRunPath = require('npm-run-path');
console.log(process.env.PATH);
//=> '/usr/local/bin'
console.log(npmRunPath());
//=> '/Users/sindresorhus/dev/foo/node_modules/.bin:/Users/sindresorhus/dev/node_modules/.bin:/Users/sindresorhus/node_modules/.bin:/Users/node_modules/.bin:/node_modules/.bin:/usr/local/bin'
// `foo` is a locally installed binary
childProcess.execFileSync('foo', {
env: npmRunPath.env()
});
```
## API
### npmRunPath(options?)
Returns the augmented path string.
#### options
Type: `object`
##### cwd
Type: `string`<br>
Default: `process.cwd()`
Working directory.
##### path
Type: `string`<br>
Default: [`PATH`](https://github.com/sindresorhus/path-key)
PATH to be appended.<br>
Set it to an empty string to exclude the default PATH.
##### execPath
Type: `string`<br>
Default: `process.execPath`
Path to the current Node.js executable. Its directory is pushed to the front of PATH.
This can be either an absolute path or a path relative to the [`cwd` option](#cwd).
### npmRunPath.env(options?)
Returns the augmented [`process.env`](https://nodejs.org/api/process.html#process_process_env) object.
#### options
Type: `object`
##### cwd
Type: `string`<br>
Default: `process.cwd()`
Working directory.
##### env
Type: `Object`
Accepts an object of environment variables, like `process.env`, and modifies the PATH using the correct [PATH key](https://github.com/sindresorhus/path-key). Use this if you're modifying the PATH for use in the `child_process` options.
##### execPath
Type: `string`<br>
Default: `process.execPath`
Path to the Node.js executable to use in child processes if that is different from the current one. Its directory is pushed to the front of PATH.
This can be either an absolute path or a path relative to the [`cwd` option](#cwd).

It's usually `PATH`, but on Windows it can be any casing like `Path`...
## Install
```
$ npm install path-key
```
## Usage
```js
const pathKey = require('path-key');
const key = pathKey();
//=> 'PATH'
const PATH = process.env[key];
//=> '/usr/local/bin:/usr/bin:/bin'
```
## API
### pathKey(options?)
#### options
Type: `object`
##### env
Type: `object`<br>
Default: [`process.env`](https://nodejs.org/api/process.html#process_process_env)
Use a custom environment variables object.
#### platform
Type: `string`<br>
Default: [`process.platform`](https://nodejs.org/api/process.html#process_process_platform)

# which
Like the unix `which` utility.
Finds the first instance of a specified executable in the PATH
environment variable. Does not cache the results, so `hash -r` is not
needed when the PATH changes.
## USAGE
```javascript
var which = require('which')
// async usage
which('node', function (er, resolvedPath) {
// er is returned if no "node" is found on the PATH
// if it is found, then the absolute path to the exec is returned
})
// or promise
which('node').then(resolvedPath => { ... }).catch(er => { ... not found ... })
// sync usage
// throws if not found
var resolved = which.sync('node')
// if nothrow option is used, returns null if not found
resolved = which.sync('node', {nothrow: true})
// Pass options to override the PATH and PATHEXT environment vars.
which('node', { path: someOtherPath }, function (er, resolved) {
if (er)
throw er
console.log('found at %j', resolved)
})
```
## CLI USAGE
Same as the BSD `which(1)` binary.
```
usage: which [-as] program ...
```
## OPTIONS
You may pass an options object as the second argument.
- `path`: Use instead of the `PATH` environment variable.
- `pathExt`: Use instead of the `PATHEXT` environment variable.
- `all`: Return all matches, instead of just the first one. Note that
this means the function returns an array of strings instead of a
single string.
