更改文件后重新启动节点 [英] Restart node upon changing a file

问题描述

对于那些来自PHP背景的人来说，杀死节点并在每次代码更改后重新启动它的过程似乎非常繁琐.在使用节点启动脚本以保存代码更改后自动重新启动节点时，是否有任何标志?

For someone who is coming from PHP background the process of killing node and starting it again after every code change, seems very tedious. Is there any flag when starting a script with node to automatically restart node when code change is saved?

推荐答案

永远模块的概念是多个node.js服务器，并且可以启动，重新启动，停止和列出当前正在运行的服务器.它还可以监视文件的更改并根据需要重新启动节点.

forever module has a concept of multiple node.js servers, and can start, restart, stop and list currently running servers. It can also watch for changing files and restart node as needed.

如果尚未安装，请安装:

Install it if you don't have it already:

npm install forever -g

安装后，调用forever命令:使用-w标志监视文件中的更改:

After installing it, call the forever command: use the -w flag to watch file for changes:

forever -w ./my-script.js

此外，您可以监视目录并忽略模式:

In addition, you can watch directory and ignore patterns:

forever --watch --watchDirectory ./path/to/dir --watchIgnore *.log ./start/file
