在package.json中创建NPM START脚本

Question

So I'm trying to create a script that when someone makes npm start it starts a localhost. Now this is what I have on my package.json :

"scripts": {
    "start": "npm run open",
    "open": "concurrently \"http-server -a localhost -p 1234\" \"sleepms 1000 && open http://localhost:1234/public/index.htm\"",
    "test": "echo \"Error: no test specified\" && exit 1"
  },

"devDependencies": {
    "concurrently": "^3.5.1",
    "http-server": "^0.10.0",
    "opn-cli": "^3.1.0",
    "sleep-ms": "^2.0.1"
  }

But what I'm getting is a 404 of the localhost...

Other question, is it possible to make so that when the user types npm start it installs or updates all dependencies?
I just recently started with Web development, please have that in mind...

Thank you

Answer 1

您应该在项目的根目录中有一个public目录，其中包含一个index.html文件。

Per the http-server documentation ...

http-server [path] [options]

[path] defaults to ./public if the folder exists, and ./ otherwise.

Since you are not passing a path, it's defaulting to ./public as its root directory, so you do not need to include /public in your URL.

Try accessing http://localhost:1234/index.htm instead of http://localhost:1234/public/index.htm
