fs-ndjson 
read and write NDJSON files (Newline Delimited JSON)
FYI
While NDJSON is often used for efficient streaming of JSON, it is also a good format for persisting and retreiving object data collections to and from disk. For example, NeDB uses the format.

API
The following fs-ndjson methods mirror the fs core module method APIs, however, the methods have been universalified so that you can use promises or callbacks for async.
- readFile
- readFileSync
- writeFile
- writeFileSync
BONUS: writeFile and writeFileSync will create the parent directory, if it does not already exist.
Installation
$ npm install --save fs-ndjsonUsage
