I’m using Sage, but each time I change the CSS or Javascript, I have to hard reload the browser, the user don’t see my change, how can I prevent this situation?
thanks
You’ll avoid this when using the production build which will version all your assets and prevent caching issues 
Simply run npm run build:production or gulp --production (depending if you’re using sage 9 or 8)

I’m using Sage 8, and this didn’t resolve my problem, the client still has an old version, js, CSS, images.
I’m doing gulp --production and deploy.
I was looking to gulp-rev:
But I didn’t have luck!
I’m trying those techniques:
EDIT: I surprised by this issue bc the production with gulp-rev create a new file based on the timestamp I imagine?
May the problem be from my server (Hostgator) and Apache?
What’s the result of the gulp --production process? You should find versioned files in your dist folder and a json manifest with the reference to those files. Those versioned files should also be pulled in the your php templates with the asset_path() helper. Have a look in the HTML of your website and see if the files are referenced correctly. Otherwise there might be something wrong in the way you’re adding them to WordPress
As @Nicolo_Sacchi said, Sage 8 will also add a unquie hash to your CSS and JS files with the production flag for cache busting purposes. You shouldn’t have to hard refresh or cache clear. Do you see the hashes at the end of your CSS and JS files in your site’s source?
the file is changed for each gulp --production:
here the page: https://freshdentalplan.com/my assets json is correct and the site works well:
~/dist]# cat
assets.json
{
"customizer.js": "customizer-301757a02e.js",
"jquery.js": "jquery-a7399e807a.js",
"main.css": "main-02f2a01f3b.css",
"main.js": "main-b08a0baf4f.js"
}
for each gulp --production, my hash in css doesn’t change, even after I added a class?
here my config.

// ### Styles

// ### Clean
// `gulp clean` - Deletes the build folder entirely.
gulp.task('clean', require('del').bind(null, [path.dist]));
// ### Watch
// `gulp watch` - Use BrowserSync to proxy your dev server and synchronize code
// changes across devices. Specify the hostname of your dev server at
// `manifest.config.devUrl`. When a modification is made to an asset, run the
// build step for that asset and inject the changes into the page.
// See: http://www.browsersync.io

// ### Build
// `gulp build` - Run all the build tasks but don't clean up beforehand.
// Generally you should be running `gulp` instead of `gulp build`.
gulp.task('build', function(callback) {
runSequence('styles',
'scripts',
['fonts', 'images'],
callback);
});
// ### Wiredep
// `gulp wiredep` - Automatically inject Less and Sass Bower dependencies. See
// https://github.com/taptapship/wiredep
gulp.task('wiredep', function() {
var wiredep = require('wiredep').stream;
return gulp.src(project.css)

.pipe(changed(path.source + 'styles', {
hasChanged: changed.compareSha1Digest
}))

});
// ### Gulp
// `gulp` - Run a complete build. To compile for production run `gulp --production`.
gulp.task('default', ['clean'], function() {
gulp.start('build');
});For each production the manifest.json doesn’t recreate a new hash.
I just notice this.
If the file hasn’t changed then this is good - no cache to bust if nothing has changed…

I changed to
.test {
}
I didn’t ecpected any change…
You’re adding the selector but you don’t have a property or value set, so it’ll minify to nothing and make no change. Add a property and value and the hash will change.
As for the issue you’re seeing, check the error logs to see if file_get_contents is disabled on your host.
