Answer 1

I think all that you need is enable "Enable JavaScript Bundling" and "Minify JavaScript Files" options in system configuration on website level in System Configuration > ADVANCED > Developer > JavaScript Settings section and redeploy static content

• Flutterer: sorry i think you dont understand the question or maybe i didnt explain it correctly . when i minify js in developer mode and after i switch to production mode then js is not minified because there is some error in the code .. i dont want to remove the error i want to minify it only .

Answer 2

Go to admin panel Stores -> Configuration -> Advanced -> Developer . You will find option to enable js minification, choose it to be Yes (This option will be visible only if your developer mode is enabled.) . In your Magento 2 ssh console run the below command to set production mode if it is not set, because minification works only in production mode:

bin/magento deploy:mode:set production --skip-compilation

Note: --skip-compilation command is not mandatory, use it if you want skip compilation, i would recommend you to not skip it. Then run the below commands:

bin/magento cache:clean
bin/magento setup:upgrade
bin/magento setup:static-content:deploy

Answer 3

To merge JavaScript files in Magento 2:

Navigate to Admin panel> Stores> Configuration> Advanced> Developer

Open the JavaScript Settings section and in the Minify JavaScript Files field, select Yes.

When complete, click Save Config.

If the above solution is not working for you due to some bugs or errors, I would try this gulp solution

Take a look at this: How to minify/optimise Javascript on Magento 2?

Although, I would strongly recommend fixing the error.
