How to do it...

To use Moment.js in an application, please follow the required steps:

First, write a wrapper in Python and use it via the jinja environment variables, as follows:

from jinja2 import Markup 
 
class momentjs(object): 
    def __init__(self, timestamp): 
        self.timestamp = timestamp 
 
    # Wrapper to call moment.js method 
    def render(self, format): 
        return Markup("<script>\ndocument.write(moment(\"%s\").%s)           ;\n</script>" % (self.timestamp.strftime("%Y-%m-           %dT%H:%M:%S"), format)) 
 
    # Format time 
    def format(self, fmt): 
        return self.render("format(\"%s\")" % fmt) 
 
    def calendar(self): 
        return self.render("calendar()") 
 
    def fromNow(self): 
        return self.render("fromNow()") 

You can add as many Moment.js methods as you want to parse to the preceding class, ...
