string-normalize-space v1.0.1

string-normalize-space is a node.js module implementing one single function, normalizeSpace, following the definition from XPath 1.0.

So it's basically like String.prototype.trim(), but also works inside the string.

The winston compatible log formatter is provided.

Installation

npm install string-normalize-space

Usage

General purpose

const {normalizeSpace} = require ('string-normalize-space')

const ab = normalizeSpace (' A\r\n\t B ') // will be 'A B'

As a winston log formatter

const {createLogger, format: {combine, printf}, transports} = require ('winston')

const normalizeSpaceLogFormat = require ('string-normalize-space').logform

const logger = createLogger ({
  transports: [
    new transports.Console (),
  ],
  format: combine (
    printf (info => `${info.message} ${info.meta} ${info.stack}`), // may be lots of \n
    normalizeSpaceLogFormat ()                                     // exactly one line
  ),
})

Notes

Unlike numerous similar modules, this one doesn't rely on any regular expressions.

As mentioned before, the XPath 1.0 specification is followed, so only 4 characters are considered "space". No effort is made to support extended Unicode space characters.
