# ldjson-stream
|
|
|
|
#### streaming line delimited json parser + serializer
|
|
|
|
[](https://nodei.co/npm/ldjson-stream/)
|
|
|
|
## usage
|
|
|
|
```
|
|
var ldj = require('ldjson-stream')
|
|
```
|
|
|
|
#### ldj.parse()
|
|
|
|
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 `ldj.parse({strict: false})`
|
|
|
|
usage:
|
|
|
|
```js
|
|
fs.createReadStream('data.txt')
|
|
.pipe(ldj.parse())
|
|
.on('data', function(obj) {
|
|
// obj is a javascript object
|
|
})
|
|
```
|
|
|
|
#### ldj.serialize()
|
|
|
|
returns a transform stream that accepts json objects and emits newline delimited json
|
|
|
|
example usage:
|
|
|
|
```js
|
|
var serialize = ldj.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()
|
|
```
