Counts number of lines in a file (or a stream)
npm install --save linecount
var linecount = require('linecount')
linecount('/usr/share/dict/words', (err, count) => {
if (err) {
throw err
}
console.log(count) // 99171
})
// Or, promised:
var linecount = require('linecount/promise')
linecount('/usr/share/dict/words')
.then(count => console.log(count))
.catch(err => console.error(err))
// You can also pass a stream. Note that this will drain the stream though, so you can't read from the same stream after counting it:
linecount(fs.createReadStream('/usr/share/dict/words'))
.then(count => console.log(count))
.catch(err => console.error(err))MIT-licensed. See LICENSE.
