surround-string v1.0.0

surround-string

Adds a prefix and a suffix to a string — but only if the string isn’t empty.

Installation

Requires Node.js 4.0.0 or above.

npm i surround-string

API

The module exports a single function.

Parameters

1. before (string): The prefix to add.
2. str (string)
3. after (string): The suffix to add.

Return Value

• If str is empty, returns an empty string.
• Otherwise, returns before + str + after.

Example

const surround = require('surround-string')

class Person {
  constructor (title, name) {
    this.title = title
    this.name = name
  }

  toString () {
    return surround('', this.title, ' ') + this.name
  }
}

(new Person('Mr.', 'Darcy')).toString() // 'Mr. Darcy'
(new Person('', 'Jane')).toString() // 'Jane'
