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.

In case you don't wanna use any library besides fs, you can do it manually.

let fileString = ""
let separator = ","
let fileType = "csv"
let file = `fileExample.${fileType}`

Object.keys(jsonObject[0]).forEach(value=>fileString += `${value}${separator}`)
    fileString = fileString.slice(0, -1)
    fileString += "\n"

    jsonObject.forEach(transaction=>{
        Object.values(transaction).forEach(value=>fileString += `${value}${separator}`)
        fileString = fileString.slice(0, -1)
        fileString += "\n"
    })

fs.writeFileSync(file, fileString, 'utf8')
