Node.js / Delete content in file

Question

I want to delete the content of a simple text file with node.js. Or replace the file with a new/empty one. How can I achieve this in node?

Accepted Answer

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 can be useful in some scenarios.
