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.

• <kbd>source*</kbd> string: The string to compare.
• <kbd>target*</kbd> 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)
console.log(grey)
