Create objects from arrays using the Streams2 API.
Rod Vagg made an awesome little tool for parsing CSV files with the Streams2 API. I wanted to take the first row of a CSV and use it as object keys for every subsequent row. As a result, Objectify Arrays was born.
It's purposely small, flexible, and lightweight so that you can bend it to fit your needs.
Install the module with:
npm install objectify-arrays
var csv2 = require'csv2'fs = require'fs'objectify = require'objectify-arrays';var objectifiedCSVRows = ;fscreateReadStream'some_csv_file.csv'pipecsv2pipeobjectifyon'data'objectifiedCSVRowspushdata;on'end' console.log;
The stream has two methods:
setHeader. If the header isn't set, it will use the first array streamed to it for the headers. If your CSV or other data source doesn't have headers, then you can just set them yourself before processing the stream.
Objectify Arrays will ignore any addition elements in an array that it doesn't have keys for.
Beyond that, it's subclassed from
stream.Transform, so it has inherited all of those abilities.
