如何在更改文件时重新加载node.js？ [英] How do I have foreman reload node.js when a file is changed?

问题描述

我目前使用主管在本地开发时运行我的node.js应用程序。这很好，但我现在将我的所有配置存储在 .bash_profile ，我想将它们移动到 .env 文件。

有没有办法使用主管的文件观看功能来获取领班的环境加载功能？

其中一种方法是将它添加到我的 Procfile 中，但我怀疑这会弄乱Heroku。

 `local：supervisor web.js` 
  

解决方案

这是我放在一起的解决方案，效果很好。

安装重新运行和 Rb-fsevent 。

  sudo gem install rerun rb-fsevent 
  

如果您还没有安装Foreman。

 sudo gem install foreman 
  

将您的环境变量放在 .env 。

不要忘记添加 .env 到您的 .gitignore ，不想要敏感信息

  echo'.env'>> .gitignore 
  

这是我的 Procfile 的样子像

  web：node web.js 
  

现在就开始像这样

 重新运行foreman start web 
  

额外信贷，创建别名

  echoalias rrun ='rerun foreman start web'>> 〜/ .bash_profile 
  

I currently use supervisor to run my node.js app when developing locally. This has been great, but I currently store all my configs in my .bash_profile, I want to move them to a .env file.

Is there a way to get the environment loading features of foreman with the file watching features of supervisor?

One option is to add it to my Procfile like this, but I suspect that will mess up Heroku.

`local: supervisor web.js`

解决方案

This is the solution I put together and it works great.

Install Rerun and Rb-fsevent.

sudo gem install rerun rb-fsevent  

Install Foreman if you have not already.

sudo gem install foreman

Put your environment variables in .env in the root of your project.

Don't forget to add .env to your .gitignore, don't want that sensitive info in your code

echo '.env' >> .gitignore  

Here is what my Procfile looks like

web: node web.js

Now just start like this

rerun foreman start web  

Extra Credit, create an alias

echo "alias rrun='rerun foreman start web'" >> ~/.bash_profile
