assembles strings into tweet sized packages

Usage no npm install needed!

<script type="module">
  import tweetPacker from '';



NPM Build Status js-standard-style

given an array of strings, tweet-packer will return a new array with those strings compacted to all be as close to 140 chars as possible (or whatever number you pass). I use this to compress tweets emitted by The Botgle Beat, which is an internet newspaper about games of boggle played over twitter.


tweetPacker(arrayOfLines, maxLength:optional, separator:optional)

  • arrayOfLines: smaller lines will be optimally joined together with the separator such that they are all less than the maxLength
  • maxLength: defaults to 140, the max length that a line can be.
  • separator: defaults to " ", perhaps "\n" is more your style? Or instead, mayhaps you prefer " : "? Have at it!


var tweetPacker = require('tweet-packer')

// GIVEN: 100 a's, 40 b's, and 30 c's
tweetPacker(["aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa", "bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb", "cccccccccccccccccccccccccccccc"])

// it tries to maximize space by combining the a's and the b's
=> ["aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb", "cccccccccccccccccccccccccccccc"]
