Split (matcher)
Break up a stream and reassemble it so that each line is a chunk. matcher may be a String, or a RegExp
Example, read every line in a file ...
fs.createReadStream(file)
.pipe(split())
.on('data', function (line) {
//each chunk now is a seperate line!
})
split takes the same arguments as string.split except it defaults to '/\r?\n/' instead of ',', and the optional limit paremeter is ignored.
String#split
NDJ - Newline Delimited Json
split accepts a function which transforms each line.
fs.createReadStream(file)
.pipe(split(JSON.parse))
.on('data', function (obj) {
//each chunk now is a a js object
})
.on('error', function (err) {
//syntax errors will land here
//note, this ends the stream.
})
