Simple but reliable CSV parser/serializer.

Features

• Simple and minimal.
• RFC 4180 compliant.
• Only few but necessary options.
• Can be easily wrapped to other API's.
• No deps.

Examples

Parse string:

import {CsvParser} from 'csv-ps';

const parser = new CsvParser();
const rows = parser.parseAll('1,2,3');

// rows: [['1', '2', '3']]

Parse by chunk:

import {CsvParser} from 'csv-ps';

const parser = new CsvParser();

const rows = [];

parser.setCallback((row) => {
    rows.push(row);
});

parser.parse('1');
parser.parse(',2,');
parser.parse('3\n');
parser.parse('4,5');
parser.parse(',6');

parser.end();

// rows: [['1', '2', '3'], ['4', '5', '6']]

Parse file:

import {CsvFileParser} from 'csv-ps';

const parser = CsvFileParser();

await parser.parse('/path/to/file.csv', (row) => {
    console.log('Got a row: %O', row);
});

Serialize rows:

import {CsvSerializer} from 'csv-ps';

const serializer = new CsvSerializer();

const serialized = serializer.serializeAll([['a', 'b', 'c']]);

// serialized: '"a","b","c"\n'
