Deploy Django App to Heroku (GUIDE):

I’m going to divide this guide into 3 phases, where each phase will have several steps. By the end of this article, you will have good amount of knowledge to deploy your projects over Heroku.

PHASE 1: Initial Setup

First of all, you need to do some initial setup before deploying your projects.

PHASE 2: Configuring Django Project To Deploy

Now we need to configure our Django project before deploying it to Heroku cloud platform. This is most important phase, so please, follow all steps very carefully.

1. Installing important packages:

You need to install two required python packages before deployment. These packages are “gunicorn” and “whitenoise“. You can install both packages by using pip or pipenv(for virtual env) command.

To install gunicorn package: “pip install gunicorn” and for whitenoise “pip install whitenoise“. Gunicorn will be used for the server and whitenoise will be used to manage static files.

2. Creating Procfile into Root

Inside your project root folder, create a file named “Procfile“. Edit Procfile content and add following text:

web: gunicorn projectname.wsgi

In the above text, you need to write your project root folder name at the place of projectname. For example, my project root folder name is crm, so, I will enter something like this: web: gunicorn crm.wsgi.

Configuring Django project for Heroku

Basically, WSGI(Web Server Gateway Interface) is a server gateway that we’re connecting with gunicorn.

3. Configuring file

Now we need to make some changes inside the file. Open your, and here you need to add STATIC_ROOT path and MIDDLEWARERE.

Middleware: ‘whitenoise.middleware.WhiteNoiseMiddleware’,

# add whitenoise middleware right after first line


# add this
STATIC_ROOT = os.path.join(BASE_DIR, 'static')

Now, this is our final phase and now we’re going to deploy our Django project to our Heroku server.

Now open your terminal and get inside you project directory then type following command one by one:

  • “git init”: To initialize git.
  • “git add .”: To add all file into your git
  • git commit -m “initial commit”“: To commit files

You need to place your app name url e.g ““.

Now again type command “git add . and “git commit -m “heroku app””

2. Deploy your project

Now you just need to type one command to deploy your project, which is:
