chunk2json

JSON parser that extracts JSON objects out of a byte stream without the use of delimeters.
Ideal for extracting JSON objects out of an incoming TCP socket byte stream.

Install

Install with npm:

$ npm install chunk2json

Use

const ChunkParser = require("chunk2json");
const parser = new ChunkParser();

parser.on("json", (jsonBuff) => {
    const result = JSON.parse(jsonBuff);
    console.log(result); // Prints the expected array
});

parser.consume(new Buffer('[{"name": "Frank Castle"'));
parser.consume(new Buffer(',"kills": true,'));
parser.consume(new Buffer('"line": "One batch, two batch, penny and dime"}'));
parser.consume(new Buffer(',{"name": "Bruce Wayne"'));
parser.consume(new Buffer(',"kills": false,'));
parser.consume(new Buffer('"line": "I am the goddamn Batman"}]'));

The parser consumes buffers which can contain partial and/or complete JSON chunks. When a complete JSON object is identified the on("json") event callback is invoked with the corresponding JSON object(in buffer form).
