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.
final Stream<String|List<int>> ndjsonStream = ...
// A new stream that will parse all chunks and emit events
// for each new json object (not ndjson chunks).
final Stream<NdjsonLine> parsedNdjson = ndjsonStream.parseNdjson();
// Using converter functions:
final Stream<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).
