.bash_profile for Git and NodeJS users

I am a Mac user, a git user, a nvm user, a NodeJS/npm user.

Here I share useful .bash_profile settings that worked for me all the time.

To run a command at `.node_modules/.bin directory`,

export PATH=$HOME/bin:./node_modules/.bin:$PATH

Without this setting, you need to specify ./node_modules/.bin/XXX to run node_modules commands such as http-server.

With this PATH setting, you can run command better.

To make use of .nvmrc

The following lines of code change your nvm environment automatically without your unnecessary $ nvm use X.XX command.

use_nvmrc() {
  if [ "$PWD" != "$PREV_PWD" ]; then
    PREV_PWD="$PWD";
    if [ -e ".nvmrc" ]; then
      nvm use;
    else
      nvm use default;
    fi
  fi
}
if [ `command -v use_nvmrc` ]; then
  export PROMPT_COMMAND="$PROMPT_COMMAND use_nvmrc;"
fi

Without the above setting, you have to switch nvm version manually although you have .nvmrc with the version you require.
