SubIn

🥙 SubIn npm travis

A tiny (115B) find-and-replace utility for strings in Javascript.

Installation

If you're using Yarn:

yarn add sub-in

npm install sub-in

Usage

Create a string with any number of placeholders: $0, $1, $2, $3, $4, etc. Placeholders are zero based:

  • $0 = ['Peter'] (Peter)
  • $1 = ['Tom', 'Peter'] (Peter)
  • $2 = ['Tom', 'John', 'Peter'] (Peter)
const greeting = 'Hey $0, how are you doing?'
subIn(greeting, ['Peter'])

// Hey Peter, how are you doing?
const friends = '$0, $1 and $2 are my friends.'
subIn(friends, ['Jake', 'Tom', 'Zack'])

// Jake, Tom and Zack are my friends
