Question

I have node installed on my server. I want to execute a JavaScript file that basically takes some information from a Django model. How could I pass JSON and large textarea variables into my node script from inside Django?

class Page(models.Model):                
    html    = models.TextField(blank = True, null = True)                
    less    = models.TextField(blank = True, null = True)
    context = models.TextField(blank = True, null = True)

    def render(self):
        # pass context (converted to JSON), less and html to node script and compile.
        # How to do this?

Thanks!

Here is how I was able to do this:

import subprocess
...
command_list = ['node', 'static/js/node_script.js']

try:
  output = subprocess.check_output(command_list)
except subprocess.CalledProcessError:
  output = "Error in command_list."
