split-json
split JSON was sent through some kind of readable stream in JSON objects
API
stream.pipe(split([match], [encoding], [replace]))
.on('data', function (data) {
console.log(split.JSONValid(data))
})
// js objects
stream.pipe(split.obj())
.on('data', function (obj) {
console.log(obj)
})- [match] => RegExp, default to os.EOL
- [encoding] => String, utf8/ascii, default to utf8
- [replace] => RegExp, enable you to remove some delimiters at begin and end of a big JSON file (ex: /(^[\n)|(\n]\n$)/)
emitters
on('data', callback(data)) on('end', [callback])
split#JSONValid
validates JSON, instead to use JSON.parse inside of a try/catch
split.JSONValid(obj) -> return object {value, error}
- value:* should be the object corresponding to the given JSON text or undefined in case of error
- error: should be an Error object in case of error or undefined in case of success
split#isObject
check is a valid Object split.isObject(obj) -> return boolean
Examples
var split = require('split-json')
// from file
var rs = fs.createReadStream('./test/file1.json')
rs.pipe(split([match])).on('data', callback)
// for mongoDB with mongojs use split#obj
var mongojs = require('mongojs')
var db = mongojs('str_conn')
var collection = db.collection('my_coll')
collection.find({})
.pipe(split.obj())
.on('data', function (doc) {
console.log(doc)
})
.on('end', function () {
db.close()
})
// TCP socket
on('data', function (data) {
var rs = new Readable()
rs.push(data)
rs.push(null)
rs.pipe(split(/\n/)).on('data', function cb (data) {
cb(null, data);
})
