Stream mode does not produce an array of JSON

[mcqj]

I am not sure what the expected behaviour is.
My output is one JSON object per line with no wrapping array and no comma separators e.g.

{name:"Joe Bloggs",status:"alive"}
{name:"Alice Kay",status:"deceased"}

etc.

+1 on this, but only when using it piped

The same here. It's a little problem.
Here is an ugly fix but anyway might by helpful so far:

import fs from 'fs';
import {Transform} from 'stream';
import csvtojson from 'csvtojson/v2';

// flag to know if it's the first chunk
let theFirstChunk = true;

// create a read stream
const rs = fs.createReadStream(src);

const csv = csvtojson({
    ignoreEmpty: true,
  })
  .subscribe((item, index) => {
    // transform of json item here what you need
  });

// create a writable stream
const ws = fs.createWriteStream(dest);

// transformation stream
const transform = new Transform({
  transform(chunk, encoding, callback) {

    const json = JSON.parse(chunk);
    let string = `,${JSON.stringify(json)}`;

    if (theFirstChunk) {
      string = '[' + string.replace(/^\,\s*/, '');
      theFirstChunk = false;
    }

    callback(null, string);
  },

  // for the last chunk add ]
  flush(callback) {
    callback(null, ']');
  }

});

rs.pipe(csv).pipe(transform).pipe(ws);

Will be covered by 2.0.9

Hi, I think that this ticket should not be closed because the array generated is syntactically incorrect, since it contains a comma after the last row:

Received result:
[
{ "Name": "Peter" },
{ "Name": "Anna" },
{ "Name": "Jean" },
]
Expected result:
[
{ "Name": "Peter" },
{ "Name": "Anna" },
{ "Name": "Jean" }
]

Using v 2.0.10.
