Server-Client

• Server:

  • Download and install

    • install npm
    • install node

  • Check installation by cmd(I used windows): npm -v to check npm installation node -v to check nodejs installation

  • Build the server

    • Go to your project directory first

    • mkDir nodeServer_HelloWorld Make a new directory, then go to that directory by cd nodeServer_HelloWorld.

    • npm init Create a new project, leave all the default settings. Then npm will create a new file: package.json automatically. (How does package.json work)

    • package.json Open package.json to see what's in there currently.

    • npm install --save express Install Express(a common web application framework), --save means you want the npm command to write in your package.json file with Express's versions, which will be added to the dependencies property.

    • npm install --save socket.io Install SocketIO library

    • Confirm that the version value have been added to dependencies property in package.json

    • echo >index.js Will create a new empty file called index.js, which is the entry point for the application.

    • Coding in index.js, see server/index.js in this repo

• Client

  • No tricky config needed. Just see the Cocos-creator project in the repo.
  • Scripts related(to socket connection): NetConfig.js, NetControl.js, SocketTest.js

Prepare your .proto files

• Create your own .proto files. See example: server/nodeServer_HelloWorld/protos/Test.userInfo.proto in this repo
• What is protobuf

Embed protobufjs in creator

• Download protobuf.js
• Import protobuf.js to creator, NOT as plugin
• Deal with .proto files from scripts, see ProtoTest.js
• How to use protobuf.js, go to official document

Embed protobufjs in Nodejs

• Go to the directory where your server is in

• npm install protobufjs --save Install protobufjs module

• Import the prepared .proto files

• pbjs -t static-module -w commonjs -o [target file(s)] [source file name] Compile .proto files and generate static code to .js files

• Reference .js files which generated from .proto, see index.js

Connect

• Run your server: node index.js
• Run the app from client
• Start communicating
