node-truncate-string

Truncates string with an ellipsis and preserves full word, if needed.

Usage:

var truncate = require("node-truncate-string");
truncate(string, length, options);

• string: String that needs to be truncated.
• length: Length of the truncated string.
• options: Options to use for truncating.

Options (Default):

{
  fullWord: true,
  splits: [" ", ",", "."],
  ellipsis: {
    char: ".",
    length: 3
  }
}

• fullWord: Whether to preserve full word when truncating. For example: truncate("fågel, kurre, flickvän, böna", 2) will return fågel. It will return få... if false.
• splits: Array list of characters where fullWord should be checked. For example: truncate("fågel, kurre, flickvän, böna", 2, {splits: " "}) will return fågel,.... But, truncate("fågel, kurre, flickvän, böna", 2, {splits: " ", ","}) will return fågel....
• ellipsis: char & length for ellipsis. Use length: 0 if you do not want any ellipsis.
