I want to set the last modified date of a file to the current date in order to avoid Parcel caching (unfortunately I didn't find a better way).

So I wrote that:

const fs = require('fs'); const file = 'test.txt'; // save the content of the file const content = fs.readFileSync(file); // modify the file fs.appendFileSync(file, ' '); // restore the file content fs.writeFileSync(file, content);

It works but meh...
It's really ugly and it's very slow and memory consuming for big files.

  • You can use touch -m test.txt Commented Jan 26, 2020 at 18:23
  • @yuko touch isn't cross-platform. I search something that will work everytime so a native Node.js function or a good NPM module. Commented Jan 26, 2020 at 18:30

    Maybe you'll find fs.utimes useful Commented Jan 26, 2020 at 18:40
  • @yuko I've just tested it and it works thanks. Commented Jan 26, 2020 at 18:50

Adapted from https://remarkablemark.org/blog/2017/12/17/touch-file-nodejs/:

const fs = require('fs'); const filename = 'test.txt'; const time = new Date(); try { fs.utimesSync(filename, time, time); } catch (err) { fs.closeSync(fs.openSync(filename, 'w')); }

fs.utimesSync is used here to prevent existing file contents from being overwritten.

It also updates the last modification timestamp of the file, which is consistent with what POSIX touch does.
