If you installed Cocos2d-js successfully. Now you can create a new project for developing Cocos2d-js game. if you dont install Cocos2d-js yet. Please follow this link.
I assume you installed Cocos2d-js . and Now open your terminal and go Cocos2d-x directory
// Create a project containing Cocos2d-x JSB and Cocos2d-html5: cocos new -l js // Create a project only containing Cocos2d-html5: cocos new -l js --no-native // Create a project with a specified name in a specified directory: cocos new projectName -l js -d ./Projects
Now you created Cocos2d-js project. Let's look how to run this project on Web Browser. When you prompt code below .it will start a web server and you can see game on browser.
cd ~/Desktop/projectName cocos run -p web
We successfully run our project on web browser. Thats it :)
