To minify multiple Javascript files, you can use Grunt. However, there is a much easier way to archive it using UglifyJS and Bashscript.
Step 1: Install UglifyJS
npm install -g uglify-js
Step 2: Write some Bash script code to find and minify all js files in a folder
for file in path/to/js/folder/*.js; do
uglifyjs "$file" --stats -c -m -o "$file"
echo minified: "$file"
done
Step 3: Run script
Save script in Step 2 to a file called 'minify-js.sh' and run it using Terminal:
sudo chmod +x minify-js.sh
./minify-js.sh
Modify this code a litte and you can use it with cleancss or other minifier.
This code help me much in deploying my webiste (a static site built with Jekyll). Hope it help someone else.
