About

This project compares the speed of different Node.JS csv parsers.

To start

$ git clone https://github.com/Keyang/csvbench
$ npm install .
$ node ./index.js

Procedure

All parsers (except lil-csv) will simply do following

1. stream in 1.csv and start to parse
2. get content from 1st column of each row and write to a file

The lil-csv would

1. read the whole 1.csv without streaming
2. get content from 1st column of each row and write to a file

1.csv contains 300K lines
