node.js Solutions

Solution 1 - node.js

You are looking for fs.truncate or fs.writeFile

Either of the following will work:

const fs = require('fs')
fs.truncate('/path/to/file', 0, function(){console.log('done')})

or

const fs = require('fs')
fs.writeFile('/path/to/file', '', function(){console.log('done')})

There are also synchronous versions of both functions that you should not use.

Solution 2 - node.js

fs.unlink is the call you need to delete a file. To replace it with different contents, just overwrite it with fs.writeFile.
