I am using csv-parser library, and i want to check table captions before parsing them
const fs = require('fs')
const csv = require('csv-parser')
fs.createReadStream('tes.csv')
.pipe(csv())
.on('start', start=>{
console.log(start)
//here i should check how column names are captioned
})
.on('data', data=>{
console.log(data)
//if they are captioned as requiered i do things
})I checked the documentation but didnt find anything about it, so there is something to use like .on('end', ()=>{})? Or there is an other way to get column names?
You can get column names with headers event. csv-parser emit headers event after header row parsed. First parameter of callback function is Array[String] and you can access column names or headers . (more doc)
const fs = require('fs')
const csv = require('csv-parser')
fs.createReadStream('tes.csv')
.pipe(csv())
.on('headers', headers=>{
console.log(headers)
})
.on('data', data=>{
console.log(data)
})
