Debugging Hints and Tips

• Enhance your Bash skills
• Check your browser's console log

To make your life a little bit easier on the command line, you can edit your ~/.bashrc file to include the following.

# MM/PM2 Related
alias cazzo='pm2 stop mm && pm2 kill;'
alias mm2='cd $HOME/MagicMirror/installers/; pm2 flush && rm ~/.pm2/logs/mm-* ; pm2 start mm.sh && cd $OLDPWD'

# PM2 Logs
alias cloge='less ~/.pm2/logs/mm-error-0.log'
alias clogo='less ~/.pm2/logs/mm-out-0.log'
alias taile='tail -f ~/.pm2/logs/mm-error-0.log'
alias tailo='tail -f ~/.pm2/logs/mm-out-0.log'

# Check and Update Packages
alias getups='sudo apt-get update'
alias getnews='apt list --upgradable'
alias lpacks='sudo dpkg --list'
alias sethold='sudo apt-mark hold'

# Some MM Locations
alias go2conf='cd $HOME/MagicMirror/config/'
alias go2mods='cd $HOME/MagicMirror/modules/'

# Screenshot from remote terminal
alias selshot=' DISPLAY=:0 scrot -s'

# Show nodejs and npm versions
alias nvers='node -v && npm -v'

Now, when you wanna run MM with a new module and check the logs while it starts, just do this:

mm2
tailo   # Use CTRL-C to quit

So if there is a crash, use cloge to read the error log.

To enable your Browsers console log, use CTRL-SHIFT-I to enable Debug Tools.
This can be used from either the main windows or from within a remote browser.
