API

The package is available by importing its default and named functions:

import erte, { c, b } from 'erte'

erte(
  source: string,
  target: string,
): string

Compares the strings using the diff package, and outputs a coloured version where strings don't match with green or red differences. Returns a string which uses shell-codes to highlight differences.

• source* string: The string to compare.
• target* string: The string to comparison against.

import erte from 'erte'
 
const s = 'test this string'
const e = 'test this string with extra data'
const m = 'test this'
 
const green = erte(s, e)
console.log(green)
 
const red = erte(s, m)
console.log(red)
 
const grey = erte(s, s)
