Node.js - create file
3 points
In this article, we would like to show you how to create a file in Node.js.
Quick solution:
xxxxxxxxxx1
const fs = require('fs');2
3
const filePath = './file.txt';4
const fileDescriptor = fs.openSync(filePath, 'w');5
6
// Hint: do not forget to close file.
In this example, we use the fs.openSync() method that returns a file descriptor to created empty file.
xxxxxxxxxx1
const fs = require('fs');2
3
const filePath = './file.txt';4
const fileDescriptor = fs.openSync(filePath, 'w');5
6
// Hint: do not forget to close file.Note:
The solution truncates the file if it exists and create new if it doesn't.
If you don’t need the file, wrap the function call in a fs.closeSync() to close it.
index.js file:
xxxxxxxxxx1
const fs = require('fs');2
3
const filePath = './file.txt';4
fs.closeSync(fs.openSync(filePath, 'w'));Running:
xxxxxxxxxx1
node index.jsResult:
