JavaScript Node.js Array to text with newline node.js array to text file,node red dashboard text

I wanted to convert an array to a textfile with a newline separating each entry.

I found out about an npm package called array-to-txt-file. Here is the webpage: array-to-txt-file

This package claims that will concatenate every element of the array with a newline, so that every element of the array appears on its own line on the text file.

So i gave it a try and while it works great it doesn't concatenate the elements with a newline. Where one element ends, another one begins.

So i took a look at the source code of the package and this is the code that creates this effect.

try {
    array.forEach(v => {
      if(_.isPlainObject(v)) {
        ws.write(`${JSON.stringify(v)}\n`)
        return
      }
      ws.write(`${v}\n`)
    })

Especially the ws.write(${v}\n) part.

I then imported my output text file into a hex editor. In the hex editor there was dot between each element. Now, this dot was different to a regular dot.

While a regular dot has the hex value of 2E, the dot that appears between the elements has 0A. Please also note that i am using Windows 7, and when viewed with notepad, nothing appears between the elements - where one ends, another one begins straight up.

So is there a way to modify that line in the code i posted above, so it really creates a newline in that part?

Answer:1

\r (0D) is CARRIAGE RETURN (CR) CHARACTER (U+000D)
\n (OA) is LINE FEED (LF) CHARACTER (U+000A)

On Linux, \n represents new line.

Two characters combined \r\n represent a new line on Windows.

Try replacing \n with \r\n in both the write statements inside index.js file of the module.

Those dots represent non-printable characters. While the regular dot . FULL STOP (U+002E) is represented by 2E.
