Deploy a django project on Heroku

We will see in this tutorial, how to deploy a django application on Heroku in step by step details. To start, you must: 

1. Download and install Git Bush on your machine:  
2. Download and install Heroku CLI on your machine:

1 - Installing Git on Windows

By default,

is installed on

and

computers as a command-line option. However, Microsoft Windows does not include a Git command. Below are the steps to install and use Git and GitHub on Microsoft Windows.  

1 - Open the Git website. 
2 - Click the Download link to download Git. The download should start automatically.
3 - Once downloaded, launch the installation from the browser or from the download folder.
4 - In the Window Select Components, leave all default options checked and check for other additional components you want to install.
5 - Next, in the Default Choice editor used by Git, unless you're familiar with Vim, we strongly recommend using a text editor you're familiar with. If Notepad++ is installed, we suggest using it as an editor.
6 - Next, in the Adjust your PATH environment, we recommend that you keep Use Git by default in the Windows Command Prompt option selected, as shown below. This option will allow you to use Git from Git Bash or Windows Command Prompt. 

7 - Then we recommend leaving the default selected under Use OpenSSH.
8 - Then, in Choice of HTTPS transport engine, leave the default value Use OpenSSL library selected.
9 - In Configure line ending conversions (Checkout Windows-style, commit Unix-style line endings), select the Checkout Windows-style, commit Unix-style line endings option unless you need other line endings for your work.
10 - In the Configure terminal emulator for use with Git Bash window, select Use MinTTY (the default terminal for MSYS2).
11 - Once done, you can check the Launch Git Bash option if you want to open a Bash command line or if you have selected the Windows command line running Git from the Windows command line.

Tip:

We strongly recommend using Git from the command line and not using a GUI. You will only use the Git interface command line to manage files. Editing can still be done through a text editor or IDE of your choice.

 5 - Creating requirement file in the root directory

To notify django of your project's dependencies, please create a requirements.txt file by executing the command:

pip freeze > requirements.txt
