## NAME

**jsesc** – escape strings for use in JavaScript string literals

## SYNOPSIS

**jsesc** \[**-s** \| **--single-quotes** *string*\]\
 \[**-d** \| **--double-quotes** *string*\]\
 \[**-w** \| **--wrap** *string*\]\
 \[**-e** \| **--escape-everything** *string*\]\
 \[**-6** \| **--es6** *string*\]\
 \[**-l** \| **--lowercase-hex** *string*\]\
 \[**-j** \| **--json** *string*\]\
 \[**-p** \| **--object** *string*\]\
 \[**-p** \| **--pretty** *string*\]\
 \[**-v** \| **--version**\]\
 \[**-h** \| **--help**\]

## DESCRIPTION

**jsesc** escapes strings for use in JavaScript string literals while generating the shortest possible valid ASCII-only output.

## OPTIONS

- **-s, --single-quotes**

  Escape any occurrences of ' in the input string as \\', so that the output can be used in a JavaScript string literal wrapped in single quotes.

- **-d, --double-quotes**

  Escape any occurrences of " in the input string as \\", so that the output can be used in a JavaScript string literal wrapped in double quotes.

- **-w, --wrap**

  Make sure the output is a valid JavaScript string literal wrapped in quotes. The type of quotes can be specified using the *-s* \| *--single-quotes* or *-d* \| *--double-quotes* settings.

- **-6, --es6**

  Escape any astral Unicode symbols using ECMAScript 6 Unicode code point escape sequences.

- **-e, --escape-everything**

  Escape all the symbols in the output, even printable ASCII symbols.

- **-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 *-d* \| *--double-quotes* and *-w* \| *--wrap* settings.

- **-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.

- **-p, --pretty**

  Pretty-print the output for objects, using whitespace to make it more readable. Setting this flag enables the

- **-l, --lowercase-hex**

  Use lowercase for alphabetical hexadecimal digits in escape sequences. *-o* \| *--object* setting.

- **-v, --version**

  Print jsesc's version.

- **-h, --help**

  Show the help screen.

## EXIT STATUS

The **jsesc** utility exits with one of the following values:

- 0

  **jsesc** successfully escaped the given string and printed the result.

- 1

  **jsesc** wasn't instructed to escape anything (for example, the *--help* flag was set); or, an error occurred.

## EXAMPLES

- **jsesc 'foo bar baz'**

  Print an escaped version of the given string.

- **echo 'foo** **bar** **baz' \| jsesc**

  Print an escaped version of the string that gets piped in.
