Django Dev Made Easy: How to Run Multiple Processes Simultaneously

Feb 10, 2023 · Updated: Feb 22, 2023 · by Tim Kamanin

As a Django developer, I have to run multiple processes while developing, such as the Django server, a JavaScript compiler, and Celery. Launching these processes separately can be time-consuming and tedious. Just try opening three terminal windows, and you'll understand what I mean.

Finally, I found a solution in the Rails community. In Rails, when they do development, they launch a single bin/dev bash file, which takes care of the rest: it launches a dev server, an asset pipeline, a queue worker, and so on.

Hey, why can't we do the same in Django?!

Actually, we can! Thus, I adopted the approach for Django and want to share it with you.

Step 1 - Create a launch file

Create a bin/dev bash file in your project's root directory. We use a bash script in this file to run multiple processes simultaneously.

#!/usr/bin/env bash

if ! command -v honcho &> /dev/null
  echo "Installing honcho…"
  pip install honcho

honcho start -f

In this file, we install and run a Python package called Hocho, a tool for managing Procfile-based applications.

Once you have created the bin/dev file, set its permissions by running the following command:

chmod +x ./bin/dev

Step 2 - Create a Procfile

For Honcho, we need a Procfile, a file in which you can declare multiple processes, or terminal commands, to launch and run simultaneously. It is exactly what we need: to run the server, Webpack, Celery, all at once.

Let\'s create a file in the root directory of your project. In this file, specify the commands for each process that you want to run:

django: python runserver
js: webpack -w
css: python tailwind start
celery: celery

In this example, the launches the Django dev server, Webpack, Tailwind CSS compiler, and Celery worker all at once.

Step 3 - Ready? Launch!

To launch all the processes, run the following command in your terminal:


And that's it! Watch the screen and enjoy the flow of command logs. You're Thomas Anderson!

Give it a try and see how it can improve your workflow.
