How to write an array to file with Node.js?

Spread the love

To write an array to file with Node.js, we call the writeFile method.

For instance, we write

require("fs").writeFile("./my.json", JSON.stringify(myArray), (err) => {
  if (err) {
    console.error("error");
  }
});

to call writeFile with the file path and a stringified version of the myArray array to write the content of myArray into the my.json file.
