在node.js脚本中运行两个脚本

Question

I am trying to run two executables in a node.js "scripts" section. One of them is a node.js executable (let's call it proc1 ) , and the other is http-server for serving some static assets. These are both process that run continuously. I'd like a way to manage these together, so that they start together, and can both be stopped together. I also want to be able to see the output of the cosmos command.

I tried configuring it like this:

"scripts": {
    "build": "http-server >> /dev/null &; proc1",
}

But this gives out the error:

sh: -c: line 0: syntax error near unexpected token ;' sh: -c: line 0: ;' sh: -c: line 0: http-server &; proc1'

I tried to find a simple node.js process management solution to run this alongside, but couldn't find an appropriate one (similar to supervisor in the Python world).

Any ideas what to do?

Answer 1

仅创建另一个node.js脚本来启动/停止这两个服务器。

Answer 2

sh: -c: line 0: syntax error near unexpected token ;' sh: -c: line 0: ;' sh: -c: line 0: http-server &; proc1'

The error is in your shell code. Change it to

"http-server >> /dev/null & proc1",

You can't end a statement with & , to run in the background, and also end it with ; .
