Remove leading space characters to let you nicely indent your multiline strings in your code.

• Node v4+

By default, multiline detects indentation by looking at the first non-empty line. Notice that the first empty line is dropped from the output to let you to start the first line with the indentation level you like.

const multiline = require('multiline-string')()
const s = multiline(`
 1. xxx
 a. yyy
 2. zzz
 `)
console.log(s)
// => "1. xxx\n a. yyy\n2. zzz"

If you want to start your string with an empty line, you can do:

const s = multiline(`

 Line 1
 Line 2
 `)
// => "\nLine 1\nLine 2\n"

You can also give marginMark to identify the start of each line to include indentation in the resulting text.

const multiline = require('multiline-string')({ marginMark: '|' })
const s = multiline(`
 | Usage: my-command file
 |
 | -v, --version Show version
 | -h, --help Show help information
 |`)
console.log(s)
// => " Usage: ...\n\n -v, --version ..."
