Write to a CSV in Node.js

Question

I am struggling to find a way to write data to a CSV in Node.js.

There are several CSV plugins available however they only \'write\' to stdout.

If you want to use a loop as you say you can do something like this with Node fs:

let fs = require("fs")

let writeStream = fs.createWriteStream('/path/filename.csv')

someArrayOfObjects.forEach((someObject, index) => {     
    let newLine = []
    newLine.push(someObject.stringPropertyOne)
    newLine.push(someObject.stringPropertyTwo)
    ....

    writeStream.write(newLine.join(',')+ '\n', () => {
        // a line was written to stream
    })
})

writeStream.end()

writeStream.on('finish', () => {
    console.log('finish write stream, moving along')
}).on('error', (err) => {
    console.log(err)
})
