如何在命令行提示符下显示当前的Firebase项目名称，以防止发生危险错误 (How to show your current Firebase project name on the command line prompt to prevent dangerous errors)

When working on a project with multiple stages (development, staging, production), developers use the command firebase use to switch between projects. It’s very easy to run a command on the production environment instead of the development. This is very dangerous.

在具有多个阶段(开发，阶段，生产)的项目上工作时，开发人员可以使用firebase use命令在项目之间进行切换。 在生产环境而不是开发环境上运行命令非常容易。 这是非常危险的。

Note: You can always find the latest script at my GitHub repository.

注意 ：您总是可以在我的GitHub存储库中找到最新的脚本。

Normally, developers only work on the development project. They only switch to production in case of checking or doing a hotfix. There have been a few times when I forgot to switch back to the development project. I accidentally changed the database without thinking that it could impact the actual users.

通常，开发人员只从事开发项目。 他们仅在检查或进行修补程序的情况下才切换到生产环境。 有好几次我忘了切换回开发项目。 我无意间更改了数据库，却没有想到这可能会影响实际用户。

Digging into the firebase CLI, I found that it uses configstore to manage local configuration. All config is saved in a JSON file and reads easily. I created a small script which is intended to show the firebase project name on shell prompt.

深入研究Firebase CLI ，我发现它使用configstore来管理本地配置。 所有配置均保存在JSON文件中，易于阅读。 我创建了一个小脚本，旨在在shell提示符下显示firebase项目名称。

如何设定 (How to set it up)

重击 (Bash)

Add the following script to the end of ~/.bash_profile:

将以下脚本添加到~/.bash_profile的末尾：

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

然后运行source ~/.bash_profile或打开一个新的终端窗口：

iTerm2与oh-my-zsh (iTerm2 with oh-my-zsh)

Oh-my-zsh is a popular open source framework for Zshell. I like it because it has many beautiful terminal themes and many useful plugins.

Oh-my-zsh是Zshell的流行开源框架。 我喜欢它，因为它有许多漂亮的终端主题和许多有用的插件。

Here, I will make an example with the agnoster theme:Edit ~/.oh-my-zsh/themes/agnoster.zsh-theme

在这里，我将以agnoster主题为例：编辑~/.oh-my-zsh/themes/agnoster.zsh-theme

and then add prompt_firebase to build_prompt functions:

然后将prompt_firebase添加到build_prompt函数：

For the final step, run source ~/.zshrc or open a new terminal window:

对于最后一步，运行source ~/.zshrc或打开一个新的终端窗口：

I hope this can help you prevent the an unexpected (and bad) situation.

我希望这可以帮助您防止出现意外(严重)情况。

Note: You can always find the latest script at my GitHub repository.

注意 ：您总是可以在我的GitHub存储库中找到最新的脚本。
