+# jsesc [![Build status](https://travis-ci.org/mathiasbynens/jsesc.svg?branch=master)](https://travis-ci.org/mathiasbynens/jsesc) [![Code coverage status](http://img.shields.io/coveralls/mathiasbynens/jsesc/master.svg)](https://coveralls.io/r/mathiasbynens/jsesc) [![Dependency status](https://gemnasium.com/mathiasbynens/jsesc.svg)](https://gemnasium.com/mathiasbynens/jsesc)
+
+This is a JavaScript library for [escaping JavaScript strings](http://mathiasbynens.be/notes/javascript-escapes) while generating the shortest possible valid ASCII-only output. [Here’s an online demo.](http://mothereff.in/js-escapes)
+
+This can be used to avoid [mojibake](http://en.wikipedia.org/wiki/Mojibake) and other encoding issues, or even to [avoid errors](https://twitter.com/annevk/status/380000829643571200) when passing JSON-formatted data (which may contain U+2028 LINE SEPARATOR, U+2029 PARAGRAPH SEPARATOR, or [lone surrogates](http://esdiscuss.org/topic/code-points-vs-unicode-scalar-values#content-14)) to a JavaScript parser or an UTF-8 encoder, respectively.
+
+Feel free to fork if you see possible improvements!
+
+## Installation
+
+Via [Bower](http://bower.io/):
+
+```bash
+bower install jsesc
+```
+
+Via [Component](https://github.com/component/component):
+
+```bash
+component install mathiasbynens/jsesc
+```
+
+Via [npm](http://npmjs.org/):
+
+```bash
+npm install jsesc
+```
+
+In a browser:
+
+```html
+<script src="jsesc.js"></script>
+```
+
+In [Node.js](http://nodejs.org/) and [RingoJS](http://ringojs.org/):
+
+```js
+var jsesc = require('jsesc');
+```
+
+In [Narwhal](http://narwhaljs.org/):
+
+```js
+var jsesc = require('jsesc').jsesc;
+```
+
+In [Rhino](http://www.mozilla.org/rhino/):
+
+```js
+load('jsesc.js');
+```
+
+Using an AMD loader like [RequireJS](http://requirejs.org/):
+
+```js
+require(
+  {
+    'paths': {
+      'jsesc': 'path/to/jsesc'
+    }
+  },
+  ['jsesc'],
+  function(jsesc) {
+    console.log(jsesc);
+  }
+);
+```
+
+## API
+
+### `jsesc(value, options)`
+
+This function takes a value and returns an escaped version of the value where any characters that are not printable ASCII symbols are escaped using the shortest possible (but valid) [escape sequences for use in JavaScript strings](http://mathiasbynens.be/notes/javascript-escapes). The first supported value type is strings:
+
+```js
+jsesc('Ich ♥ Bücher');
+// → 'Ich \\u2665 B\\xFCcher'
+
+jsesc('foo 𝌆 bar');
+// → 'foo \\uD834\\uDF06 bar'
+```
+
+Instead of a string, the `value` can also be an array, or an object. In such cases, `jsesc` will return a stringified version of the value where any characters that are not printable ASCII symbols are escaped in the same way.
+
+```js
+// Escaping an array
+jsesc([
+  'Ich ♥ Bücher', 'foo 𝌆 bar'
+]);
+// → '[\'Ich \\u2665 B\\xFCcher\',\'foo \\uD834\\uDF06 bar\']'
+
+// Escaping an object
+jsesc({
+  'Ich ♥ Bücher': 'foo 𝌆 bar'
+});
+// → '{\'Ich \\u2665 B\\xFCcher\':\'foo \\uD834\\uDF06 bar\'}'
+```
+
+The optional `options` argument accepts an object with the following options:
+
+#### `quotes`
+
+The default value for the `quotes` option is `'single'`. This means that any occurences of `'` in the input string will be escaped as `\'`, so that the output can be used in a string literal wrapped in single quotes.
+
+```js
+jsesc('Lorem ipsum "dolor" sit \'amet\' etc.');
+// → 'Lorem ipsum "dolor" sit \\\'amet\\\' etc.'
+
+jsesc('Lorem ipsum "dolor" sit \'amet\' etc.', {
+  'quotes': 'single'
+});
+// → 'Lorem ipsum "dolor" sit \\\'amet\\\' etc.'
+// → "Lorem ipsum \"dolor\" sit \\'amet\\' etc."
+```
+
+If you want to use the output as part of a string literal wrapped in double quotes, set the `quotes` option to `'double'`.
+
+```js
+jsesc('Lorem ipsum "dolor" sit \'amet\' etc.', {
+  'quotes': 'double'
+});
+// → 'Lorem ipsum \\"dolor\\" sit \'amet\' etc.'
+// → "Lorem ipsum \\\"dolor\\\" sit 'amet' etc."
+```
+
+This setting also affects the output for arrays and objects:
+
+```js
+jsesc({ 'Ich ♥ Bücher': 'foo 𝌆 bar' }, {
+  'quotes': 'double'
+});
+// → '{"Ich \\u2665 B\\xFCcher":"foo \\uD834\\uDF06 bar"}'
+
+jsesc([ 'Ich ♥ Bücher', 'foo 𝌆 bar' ], {
+  'quotes': 'double'
+});
+// → '["Ich \\u2665 B\\xFCcher","foo \\uD834\\uDF06 bar"]'
+```
+
+#### `wrap`
+
+The `wrap` option takes a boolean value (`true` or `false`), and defaults to `false` (disabled). When enabled, the output will be a valid JavaScript string literal wrapped in quotes. The type of quotes can be specified through the `quotes` setting.
+
+```js
+jsesc('Lorem ipsum "dolor" sit \'amet\' etc.', {
+  'quotes': 'single',
+  'wrap': true
+});
+// → '\'Lorem ipsum "dolor" sit \\\'amet\\\' etc.\''
+// → "\'Lorem ipsum \"dolor\" sit \\\'amet\\\' etc.\'"
+
+jsesc('Lorem ipsum "dolor" sit \'amet\' etc.', {
+  'quotes': 'double',
+  'wrap': true
+});
+// → '"Lorem ipsum \\"dolor\\" sit \'amet\' etc."'
+// → "\"Lorem ipsum \\\"dolor\\\" sit \'amet\' etc.\""
+```
+
+#### `es6`
+
+The `es6` option takes a boolean value (`true` or `false`), and defaults to `false` (disabled). When enabled, any astral Unicode symbols in the input will be escaped using [ECMAScript 6 Unicode code point escape sequences](http://mathiasbynens.be/notes/javascript-escapes#unicode-code-point) instead of using separate escape sequences for each surrogate half. If backwards compatibility with ES5 environments is a concern, don’t enable this setting. If the `json` setting is enabled, the value for the `es6` setting is ignored (as if it was `false`).
+
+```js
+// By default, the `es6` option is disabled:
+jsesc('foo 𝌆 bar 💩 baz');
+// → 'foo \\uD834\\uDF06 bar \\uD83D\\uDCA9 baz'
+
+// To explicitly disable it:
+jsesc('foo 𝌆 bar 💩 baz', {
+  'es6': false
+});
+// → 'foo \\uD834\\uDF06 bar \\uD83D\\uDCA9 baz'
+
+// To enable it:
+jsesc('foo 𝌆 bar 💩 baz', {
+  'es6': true
+});
+// → 'foo \\u{1D306} bar \\u{1F4A9} baz'
+```
+
+#### `escapeEverything`
+
+The `escapeEverything` option takes a boolean value (`true` or `false`), and defaults to `false` (disabled). When enabled, all the symbols in the output will be escaped, even printable ASCII symbols.
+
+```js
+jsesc('lolwat"foo\'bar', {
+  'escapeEverything': true
+});
+// → '\\x6C\\x6F\\x6C\\x77\\x61\\x74\\"\\x66\\x6F\\x6F\\\'\\x62\\x61\\x72'
+// → "\\x6C\\x6F\\x6C\\x77\\x61\\x74\\\"\\x66\\x6F\\x6F\\'\\x62\\x61\\x72"
+```
+
+This setting also affects the output for arrays and objects:
+
+```js
+jsesc({ 'Ich ♥ Bücher': 'foo 𝌆 bar' }, {
+  'escapeEverything': true
+});
+// → '{\'\x49\x63\x68\x20\u2665\x20\x42\xFC\x63\x68\x65\x72\':\'\x66\x6F\x6F\x20\uD834\uDF06\x20\x62\x61\x72\'}'
+// → "{'\x49\x63\x68\x20\u2665\x20\x42\xFC\x63\x68\x65\x72':'\x66\x6F\x6F\x20\uD834\uDF06\x20\x62\x61\x72'}"
+
+jsesc([ 'Ich ♥ Bücher': 'foo 𝌆 bar' ], {
+  'escapeEverything': true
+});
+// → '[\'\x49\x63\x68\x20\u2665\x20\x42\xFC\x63\x68\x65\x72\',\'\x66\x6F\x6F\x20\uD834\uDF06\x20\x62\x61\x72\']'
+```
+
+#### `compact`
+
+The `compact` option takes a boolean value (`true` or `false`), and defaults to `true` (enabled). When enabled, the output for arrays and objects will be as compact as possible; it won’t be formatted nicely.
+
+```js
+jsesc({ 'Ich ♥ Bücher': 'foo 𝌆 bar' }, {
+  'compact': true // this is the default
+});
+// → '{\'Ich \u2665 B\xFCcher\':\'foo \uD834\uDF06 bar\'}'
+
+jsesc({ 'Ich ♥ Bücher': 'foo 𝌆 bar' }, {
+  'compact': false
+});
+// → '{\n\t\'Ich \u2665 B\xFCcher\': \'foo \uD834\uDF06 bar\'\n}'
+
+jsesc([ 'Ich ♥ Bücher', 'foo 𝌆 bar' ], {
+  'compact': false
+});
+// → '[\n\t\'Ich \u2665 B\xFCcher\',\n\t\'foo \uD834\uDF06 bar\'\n]'
+```
+
+This setting has no effect on the output for strings.
+
+#### `indent`
+
+The `indent` option takes a string value, and defaults to `'\t'`. When the `compact` setting is enabled (`true`), the value of the `indent` option is used to format the output for arrays and objects.
+
+```js
+jsesc({ 'Ich ♥ Bücher': 'foo 𝌆 bar' }, {
+  'compact': false,
+  'indent': '\t' // this is the default
+});
+// → '{\n\t\'Ich \u2665 B\xFCcher\': \'foo \uD834\uDF06 bar\'\n}'
+
+jsesc({ 'Ich ♥ Bücher': 'foo 𝌆 bar' }, {
+  'compact': false,
+  'indent': '  '
+});
+// → '{\n  \'Ich \u2665 B\xFCcher\': \'foo \uD834\uDF06 bar\'\n}'
+
+jsesc([ 'Ich ♥ Bücher', 'foo 𝌆 bar' ], {
+  'compact': false,
+  'indent': '  '
+});
+// → '[\n  \'Ich \u2665 B\xFCcher\',\n\  t\'foo \uD834\uDF06 bar\'\n]'
+```
+
+This setting has no effect on the output for strings.
+
+#### `json`
+
+The `json` option takes a boolean value (`true` or `false`), and defaults to `false` (disabled). When enabled, the output is valid JSON. [Hexadecimal character escape sequences](http://mathiasbynens.be/notes/javascript-escapes#hexadecimal) and [the `\v` or `\0` escape sequences](http://mathiasbynens.be/notes/javascript-escapes#single) will not be used. Setting `json: true` implies `quotes: 'double', wrap: true, es6: false`, although these values can still be overridden if needed — but in such cases, the output won’t be valid JSON anymore.
+
+```js
+jsesc('foo\x00bar\xFF\uFFFDbaz', {
+  'json': true
+});
+// → '"foo\\u0000bar\\u00FF\\uFFFDbaz"'
+
+jsesc({ 'foo\x00bar\xFF\uFFFDbaz': 'foo\x00bar\xFF\uFFFDbaz' }, {
+  'json': true
+});
+// → '{"foo\\u0000bar\\u00FF\\uFFFDbaz":"foo\\u0000bar\\u00FF\\uFFFDbaz"}'
+
+jsesc([ 'foo\x00bar\xFF\uFFFDbaz', 'foo\x00bar\xFF\uFFFDbaz' ], {
+  'json': true
+});
+// → '["foo\\u0000bar\\u00FF\\uFFFDbaz","foo\\u0000bar\\u00FF\\uFFFDbaz"]'
+
+// Values that are acceptable in JSON but aren’t strings, arrays, or object
+// literals can’t be escaped, so they’ll just be preserved:
+jsesc([ 'foo\x00bar', [1, '©', { 'foo': true, 'qux': null }], 42 ], {
+  'json': true
+});
+// → '["foo\\u0000bar",[1,"\\u00A9",{"foo":true,"qux":null}],42]'
+// Values that aren’t allowed in JSON are run through `JSON.stringify()`:
+jsesc([ undefined, -Infinity ], {
+  'json': true
+});
+// → '[null,null]'
+```
+
+**Note:** Using this option on objects or arrays that contain non-string values relies on `JSON.stringify()`. For legacy environments like IE ≤ 7, use [a `JSON` polyfill](http://bestiejs.github.io/json3/).
+
+### `jsesc.version`
+
+A string representing the semantic version number.
+
+### Using the `jsesc` binary
+
+To use the `jsesc` binary in your shell, simply install jsesc globally using npm:
+
+```bash
+npm install -g jsesc
+```
+
+After that you will be able to escape strings from the command line:
+
+```bash
+$ jsesc 'föo ♥ bår 𝌆 baz'
+f\xF6o \u2665 b\xE5r \uD834\uDF06 baz
+```
+
+To escape arrays or objects containing string values, use the `-o`/`--object` option:
+
+```bash
+$ jsesc --object '{ "föo": "♥", "bår": "𝌆 baz" }'
+{'f\xF6o':'\u2665','b\xE5r':'\uD834\uDF06 baz'}
+```
+
+To prettify the output in such cases, use the `-p`/`--pretty` option:
+
+```bash
+$ jsesc --pretty '{ "föo": "♥", "bår": "𝌆 baz" }'
+{
+  'f\xF6o': '\u2665',
+  'b\xE5r': '\uD834\uDF06 baz'
+}
+```
+
+For valid JSON output, use the `-j`/`--json` option:
+
+```bash
+$ jsesc --json --pretty '{ "föo": "♥", "bår": "𝌆 baz" }'
+{
+  "f\u00F6o": "\u2665",
+  "b\u00E5r": "\uD834\uDF06 baz"
+}
+```
+
+Read a local JSON file, escape any non-ASCII symbols, and save the result to a new file:
+
+```bash
+$ jsesc --json --object < data-raw.json > data-escaped.json
+```
+
+Or do the same with an online JSON file:
+
+```bash
+$ curl -sL "http://git.io/aorKgQ" | jsesc --json --object > data-escaped.json
+```
+
+See `jsesc --help` for the full list of options.
+
+## Support
+
+This library has been tested in at least Chrome 27-29, Firefox 3-22, Safari 4-6, Opera 10-12, IE 6-10, Node.js v0.10.0, Narwhal 0.3.2, RingoJS 0.8-0.9, PhantomJS 1.9.0, and Rhino 1.7RC4.
+
+**Note:** Using the `json` option on objects or arrays that contain non-string values relies on `JSON.parse()`. For legacy environments like IE ≤ 7, use [a `JSON` polyfill](http://bestiejs.github.io/json3/).
+
+## Unit tests & code coverage
+
+After cloning this repository, run `npm install` to install the dependencies needed for development and testing. You may want to install Istanbul _globally_ using `npm install istanbul -g`.
+
+Once that’s done, you can run the unit tests in Node using `npm test` or `node tests/tests.js`. To run the tests in Rhino, Ringo, Narwhal, and web browsers as well, use `grunt test`.
+
+To generate the code coverage report, use `grunt cover`.

+.Nd escape strings for use in JavaScript string literals
+.Sh SYNOPSIS
+.Nm
+.Op Fl s | -single-quotes Ar string
+.br
+.Op Fl d | -double-quotes Ar string
+.br
+.Op Fl w | -wrap Ar string
+.br
+.Op Fl 6 | -es6 Ar string

+.Sh DESCRIPTION
+.Nm
+escapes strings for use in JavaScript string literals while generating the shortest possible valid ASCII-only output.
+.Sh OPTIONS
+.Bl -ohang -offset
+.It Sy "-s, --single-quotes"
+Escape any occurences of ' in the input string as \\', so that the output can be used in a JavaScript string literal wrapped in single quotes.
+.It Sy "-d, --double-quotes"
+Escape any occurences of " in the input string as \\", so that the output can be used in a JavaScript string literal wrapped in double quotes.
+.It Sy "-w, --wrap"
+Make sure the output is a valid JavaScript string literal wrapped in quotes. The type of quotes can be specified using the
+.Ar -s | --single-quotes
+or
+.Ar -d | --double-quotes
+settings.
+.It Sy "-6, --es6"
+Escape any astral Unicode symbols using ECMAScript 6 Unicode code point escape sequences.
+.It Sy "-e, --escape-everything"
+Escape all the symbols in the output, even printable ASCII symbols.
+.It Sy "-j, --json"
+Make sure the output is valid JSON. Hexadecimal character escape sequences and the \\v or \\0 escape sequences will not be used. Setting this flag enables the
+.Ar -d | --double-quotes
+and
+.Ar -w | --wrap
+settings.
+.It Sy "-o, --object"
+Treat the input as a JavaScript object rather than a string. Accepted values are flat arrays containing only string values, and flat objects containing only string values.
+.It Sy "-p, --pretty"
+Pretty-print the output for objects, using whitespace to make it more readable. Setting this flag enables the
+.Ar -o | --object
+setting.
+.It Sy "-v, --version"
+Print jsesc's version.
+.It Sy "-h, --help"
+Show the help screen.
+.El
+.Sh EXIT STATUS
+The
+.Nm jsesc
+utility exits with one of the following values:
+.Pp
+.Bl -tag -width flag -compact
+.It Li 0
+.Nm
+successfully escaped the given string and printed the result.
+.It Li 1
+.Nm
+wasn't instructed to escape anything (for example, the
+.Ar --help
+flag was set); or, an error occurred.
+.El
+.Sh EXAMPLES
+.Bl -ohang -offset
+.It Sy "jsesc 'foo bar baz'"
+Print an escaped version of the given string.
+.It Sy echo\ 'foo bar baz'\ |\ jsesc
+Print an escaped version of the string that gets piped in.
