Firebase prompt

Show current firebase project on terminal prompt

When working on multiple stages (development, staging, production), developers usually use

firebase use [project_id_or_alias]

to switch between projects. It's very easy to run a command on production environment instead of development, which is very dangerous.

This script intends to show firebase project name on shell prompt. I hope this can help prevent unexpected situation.

How to set up

1. Bash

Add following script to the end of ~/.bash_profile

prompt_firebase() {
  local fb_project=$(grep \"$(pwd)\" ~/.config/configstore/firebase-tools.json | cut -d" " -f2)
  if [[ -n $fb_project ]]; then
    echo [$fb_project]
  fi
}
export PS1="\$(prompt_firebase)"$PS1

Then run source ~/.bash_profile or open new terminal window

2. iTerm2 with oh-my-zsh

For example, if you're using agnoster theme: Edit ~/.oh-my-zsh/themes/agnoster.zsh-theme

prompt_firebase() {
  local fb_project=$(grep \"$(pwd)\" ~/.config/configstore/firebase-tools.json | cut -d" " -f2)
  if [[ -n $fb_project ]]; then
    prompt_segment red black $fb_project
  fi
}

and add prompt_firebase to build_prompt functions

build_prompt() {
  RETVAL=$?
  prompt_status
  prompt_virtualenv
  prompt_context
  prompt_dir
  prompt_git
  prompt_bzr
  prompt_hg
  prompt_firebase
  prompt_end
}

Then run source ~/.zshrc or open new terminal window
