How to install socket.io and mysql on Node.js

Question

I'm too newbie to Node.js.

I'm trying to setup a basic site (in order to learn), to make a call from Javascript in front end to Node.js and return the data of a mysql query.

I followed some tutorials in internet and I made this packages.json file

{
    "name": "Stock",
    "version": "0.0.1",
    "devDependencies": {
        "grunt": "~0.4.5",
        "grunt-contrib-watch": "^0.6.1",
        "grunt-execute": "^0.2.2",
        "socket.io":"lastest"
    }
}

Then on my Linux I run: npm install Which I understand it will install all dependencies listed on the packages.json. But I'm getting this error:

npm WARN package.json Stock@0.0.1 No description
npm WARN package.json Stock@0.0.1 No repository field.

I guess latest version for socket.io, is not ok? how would it work?

Part of the code I get from Here

Answer 1

You have a typo in the socket.io version. "socket.io":"lastest" should be changed to "socket.io":"latest" .

Answer 2

应该是“最新的”而不是“最新的”
