How to do proxy to avoid CORS for ionic2 apps?

Try to use chrome with --disable-web-security

you will find many articles on how to disable-web-security of chrome for only development purpose…

assuming you are using MAC machine…
try this command on terminal…

open -n -a “Google Chrome” --args --user-data-dir=/tmp/temp_chrome_user_data_dir_for_cordova http://localhost:8100/ --disable-web-security

which opens another instance of chrome with disabled security and there is no CORS issue any more… as per I know this command will not hamper your original chrome’s security…
