Run node.js server locally-CodePudding

I'm trying to run my node.js server locally. Before, I had done it in Replit, where it makes it easy to set up. I'm a little stuck though.

I have a folder for my project, with a server.js file, package.json, package-lock.json, and a public folder containing index.html. I'm using socket.io, express, http, and cookie-parser. They are all in a node_modules folder.

In server.js, I use
const { Server } = require('socket.io');
This worked in Replit.

The package.json file contains these dependencies:

"dependencies": {
    "body-parser": "^1.19.1",
    "cookie": "^0.4.1",
    "cookie-parser": "^1.4.6",
    "express": "^4.17.2",
    "socket.io": "^4.4.1"
  }

I use the command
.load correct\path\to\server.js
in the Node.js command line.

When I run server.js in Node.js, I get this message:
Cannot find module 'socket.io'

Help?

CodePudding user response：

Sounds like you need to install the dependencies, try executing npm install, after that you use "node" to run your code.

For example: node correct\path\to\server.js

CodePudding user response：

You need to install all the dependent modules through npm install, In your case, you need to install

node-SQL server

npm install node-sqlserver

Generally your source code will be having a

package.json

. This file specifies all the dependent modules required to run the application, but here this file is missing.
