Gulp: how to change file modification time

Question

I have a gulp task below and every time I run this task (before browsersync). I want to change the last modification time of one file (nothing changes in this file, I just need to change the time of the last modification - an alternative to shell "touch"). Can someone tell me the easiest way to do this, please? Thanks!

gulp.task('sass', function() { return sass(pkg.sass.dir, {sourcemap: true, precision: 10}) .on('error', function (err) { onError(err); }) .pipe(autoprefixer({ browsers: ['last 2 version', 'safari 5', 'ie 8', 'ie 9', 'opera 12.1', 'ios 6', 'android 4'], cascade: true })) .pipe(gulp.dest(pkg.css.dir)) .pipe(browsersync.reload({stream:true})); }); 

Answer 1

Use the core fs fs.utimes module , which is the analogue of node for the Unix touch command. You pass the path, and if you pass new Date() as the mtime parameter, this should do the trick.

Answer 2

gulp-touch-cmd and gulp-touch don't seem to work with Gulp 4, so I wrote this little tube function that works. ( npm add through2 )

 // example .pipe( through2.obj( function( file, enc, cb ) { let date = new Date(); file.stat.atime = date; file.stat.mtime = date; cb( null, file ); }) ) .pipe( gulp.dest( '.' ) ) 

Answer 3

just you can use gulp-touch-cmd

Change file access time and file modification time of files copied with gulp

 npm install --save-dev gulp-touch-cmd var gulp = require('gulp'); var touch = require('gulp-touch-cmd'); gulp.task('default', function() { gulp .src('./src/**/*') .pipe(gulp.dest('./dest')) .pipe(touch()); });

Gulp gulp-touch-fd plugin fixes Gulp 4 compatibility issue with gulp-touch

 npm install --save-dev gulp-touch-fd@funkedigital /gulp-touch-fd 

Example:

 const {src, dest} = require('gulp'); const touch = require('gulp-touch-fd'); function copyAndTouch() { return src('./src/**/*') .pipe(dest('./dest')) .pipe(touch()); }; exports.copyAndTouch = copyAndTouch
