How to specify a tab delimiter in PapaParse?

Question

I receive a delimiter like so:

var delimiter = process.argv[3];
if (!delimiter) {
  console.log('Please specify a delimiter as the second argument in the CLI');
  process.exit(0);
}
console.log('with delimiter:', delimiter);

And I attempt to use it with PapaParse like this:

  Papa.parse(fs.createReadStream(__dirname + relativePathToFile, 'utf8'), {
    delimiter: delimiter,
    header: true,
    skipEmptyLines: true,

But regardless of passing in \t or \\t from CLI, neither works. What value exactly does PapaParse want us to pass for it to be identified as the tab delimiter?

Answer 1

I've had success passing in \t directly, like so: delimiter: '\t' But I'm not sure how that translates to pulling it from a function.

Answer 2

Specify spaces as required, for tab delimiter should have 5 spaces

Answer 3

It's ugly, but it should work

Papa.parse(fs.createReadStream(__dirname + relativePathToFile, 'utf8'), {
    delimiter: delimiter === "\\t" ? "\t" : delimiter,
    header: true,
    skipEmptyLines: true,
