Basically, how do I create the callback api? UPDATE My server side language is PHP 回答1: It is simple. Simply accept a parameter called callback in the GET. Then wrap the callback JavaScript function around your data. Example in PHP: <?php $data = '{}'; // json

I want the app to be as lean as possible and only want to include the js references that are required for the present view. Is it possible to load the js files dynamically based on a view? 回答1: I think this

Popen ( '/path/to/script' , stdout = subprocess . PIPE , stderr = subprocess . PIPE ) result = p . communicate () I then print the result to the stdout. This is all fine but as the script takes a long time to complete, I wanted real time output from the script to stdout as well. The reason I pipe the output is because I want to parse it. 回答1: To save subprocess' stdout to a variable for further processing and to display

I've followed the quick start guide and has a general idea of how Webpack works, but I'm unclear on how to load dependency library like jquery / backbone / underscore.

Thanks 回答1: It's both possible
