ndjson¶ ↑
streaming newline delimited json parser + serializer. Available as a JS API or a command line tool
usage¶ ↑
var ndjson = require('ndjson')
ndjson.parse(opts)¶ ↑
returns a transform stream that accepts newline delimited json and emits objects
example newline delimited json:
data.txt
:
{"foo": "bar"} {"hello": "world"}
If you want to discard non-valid JSON messages, you can call ndjson.parse({strict: false})
usage:
fs.createReadStream('data.txt') .pipe(ndjson.parse()) .on('data', function(obj) { // obj is a javascript object })
ndjson.serialize() / ndjson.stringify()¶ ↑
returns a transform stream that accepts json objects and emits newline delimited json
example usage:
var serialize = ndjson.serialize() serialize.on('data', function(line) { // line is a line of stringified JSON with a newline delimiter at the end }) serialize.write({"foo": "bar"}) serialize.end()
