This page describes the ndjson format, also called Newline delimited JSON. NDJSON is a convenient format for storing or streaming structured data that may be processed one record at a time. It works well with unix-style text processing tools and shell pipelines. It's a great format for log files. It's also a flexible format for passing messages between cooperating processes.
'\r\n' is also supported because trailing white space is ignored when parsing JSON values.
The most common values will be objects or arrays, but any JSON value is permitted. See json.org for more information about JSON values.
