XPath 1.0 normalize-space analog, winston log formatter
npm install string-normalize-spacestring-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.
``
npm install string-normalize-space
`js
const {normalizeSpace} = require ('string-normalize-space')
const ab = normalizeSpace (' A\r\n\t B ') // will be 'A B'
`
log formatter`js
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
),
})
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.
