Read local CSV with relative path in ReactJS

Question

With reactjs (in Meteor) I would like to read a local csv file with a relative path and loop over it's rows:

import Papa from 'papaparse';
var csvfile = "../../../data.csv";
Papa.parse(csvfile, {
  step: function (row) {
    console.log("Row:", row.data);
  },
});

This returns

Row: [ [ '../../../data.csv' ] ]

Answer 1

Looks like your library expect JSON, whereas you specified a path.

You should read the JSON from your file using fs and then pass that to the parse method.

fs.readFile(csvFile, 'utf8', function (err, data) {
    if (err) {
        throw err;
    }
    Papa.parse(data, {
     step: function (row) {
      console.log("Row:", row.data);
     }
   });
});
