petShopIndex.html:137 Uncaught ReferenceError: $ is not defined jquery node


Here is what the above code is Doing:
1. We’re importing the Flask class from the flask module.
2. We’re creating a new instance of the Flask class. The first argument is the name of the application’s module or package. If you are using a single module (as in this example), you should use __name__ because depending on if it’s started as application or imported as module the name will be different (‘__main__’ versus the actual import name). This is needed so that Flask knows where to look for templates, static files, and so on. For more information have a look at the Flask documentation.
3. We then load the configuration from the config.py file.
4. We define the route for the index or the root of the site. This function returns the rendered template ‘index.html’ which we will create in the next step.
5. We then start the development web server using the run() method.
