fs.openSync() provided by the
fs built-in module is the best way.
It returns a file descriptor:
const fs = require('fs') const filePath = './.data/initialized' const fd = fs.openSync(filePath, 'w')
w flag makes sure the file is created if not existing, and if the file exists it overwrites it with a new file, overriding its content.
a flag to avoid overwriting. The file is still created if not existing.
If you don’t need the file descriptor, you can wrap the call in a
fs.closeSync() call, to close the file:
const fs = require('fs') const filePath = './.data/initialized' fs.closeSync(fs.openSync(filePath, 'w'))
