parse-csv-stream

Parse any csv file via stream or csv stream from any other source in Node.js for various usecases like database insertion, logging, file creation, batch processing data etc.

Example:

const parse_csv = require('parse-csv-stream');
const fs = require('fs');

const readStream = fs.createReadStream('./test.csv', 'utf8');
const writeStream = fs.createWriteStream('./test.json');

//default option.
const options = {
    // delimiter: ',',
    // wrapper: '"',
    // newlineSeperator: '\r\n'
};

const parser = new parse_csv(options);
const events = parser.events;

//There are 2 approaches you can take : events, stream, choose any one.

// [1.] working with events.
events.on('data', (row) => {
    console.log(row);
})

readStream.on('data', (chunk) => {
    parser.parse(chunk);
});

//[2.] Working with streams.
readStream.pipe(parser).pipe(writeStream);
