TypeError: csv.fromPath is not a function (convert csv file to sha1 script)

Question

im trying to execute a sample script that reads a CSV file. and then make the data into SHA1 hash. I copied the sample from this git:

https://gist.github.com/cdurth/6735c82cd11c5a057bd4

I get this error:

C:\Users\test\Desktop\convert\csvParseToSha1.js:14
 .fromPath(inputFile)
  ^

TypeError: csv.fromPath is not a function

The sample code:

var fs = require('fs');
var csv = require("fast-csv");
var sha1 = require('sha1');

var inputFile = 'emailList.csv';
var outputFile = 'sha1List.csv';

var csvStream = csv.format({headers: false}),
    writableStream = fs.createWriteStream(outputFile);

csvStream.pipe(writableStream);

csv
 .fromPath(inputFile)
 .on("data", function(data){
   var hashed = sha1(data[0])
   csvStream.write([hashed]);
 })
 .on("end", function(){
     csvStream.end();
     console.log("done");
 });

the fast-csv version is 4.1.3

Answer 1

for 'fast-csv' version >= 3.0.0 :- fromPath deprecated
