Sometimes, we want to append to new line in Node.js.
In this article, we’ll look at how to append to new line in Node.js.
How to append to new line in Node.js?
To append to new line in Node.js, we can use the os.EOL constant.
For instance, we write
const os = require("os");
const processInput = (text) => {
fs.open("H://log.txt", "a", 666, (e, id) => {
fs.write(id, text + os.EOL, null, "utf8", () => {
fs.close(id, () => {
console.log("file is updated");
});
});
});
};
to log the log.txt file with append permission with fs.open.
In the fs.open callback, we call fs.write to add the os.EOL end of line character after the text.
Then we call fs.close in the write callback to close the file.
