how can i run gulp automatically when ionic serve / live reloading ?
i have add this config

"scripts": { 
    "ionic:serve:before" : "gulp" ,
    "ionic:build:before" : "gulp"

at my package.json file, and it do run gulp before finish serve. But when i change any html file and trigger the live reloading, the gulp not triggered anymore. I also tried to add :

gulp.task('ionic:serve:before', gulp.series('default'),
function (done) {

in my gulpfile.js but its not working too. Please throw some enlightment for anyone who ever encountered this case before. Thanks in advanceā€¦
