ndjson parser for Dart

Tiny and simple ndjson parser library for Dart. No external dependencies.

Installation

dependencies:
ndjson: ^<latest-version>

Import:

import'package:ndjson/ndjson.dart';

Usage

The usage is pretty straightforward:

import'package:ndjson/ndjson.dart';
// Your ndjson stream.finalStream<String|List<int>> ndjsonStream = ...
// A new stream that will parse all chunks and emit events // for each new json object (not ndjson chunks).finalStream<NdjsonLine> parsedNdjson = ndjsonStream.parseNdjson();
// Using converter functions:finalStream<Dummy> ndjson = ndjsonSource.parseNdjsonWithConverter<Dummy>(
whenMap:Dummy.fromJson,
);

---

Supported ndjson types are:

• Stream<List<int>>.
• Stream<Uint8List>.
• Stream<String>.

---

Any list-like ndjson source can be converted to Stream using:

Stream.fromIterable(ndjsonList);

You must be aware that using ndjson as list is the same as a regular json (you lose all ndjson performance benefits).
