   INSTALLED_APPS = [
      '..................',
      'django-webpacker',
      '..................'
   ]

3. Run npm init to intialize npm modules and it will create ‘package.json’ file which will contain package information. Update file with following dependencies:

   npm install

5. Updates Your html file with the following script, link stylesheet tags.

   <link rel=”stylesheet” type=”text/css” href=”” id=”packer_css”/>

   <script id=”packer_js” src=”” type=”text/javascript”></script>

6. Create webpack.config.js file with webpack.config.js file data. Update your project entry points with their respective paths. We can give multiple entry points(i.e separate entry point for each app) for the project. After compressing, separate css, file will be genarated with respective entry point name.

7. Add the following details in settings file about compressing css, js files:

   WEB_PACK_FILES = [
       {'html_file_name': {{ HTML_FILE_RELATIVE_PATH }},
        'webpack_js': {{ WEBPACK_ENTRY_POINT_KEY_NAME }},
       },
       {'html_file_name': {{ HTML_FILE_RELATIVE_PATH }},
        'webpack_js': {{ WEBPACK_ENTRY_POINT_KEY_NAME }},
        },
       {'html_file_name': {{ HTML_FILE_RELATIVE_PATH }}',
        'webpack_js': {{ WEBPACK_ENTRY_POINT_KEY_NAME }},
        },
   ]

8. Run python manage.py compress_css_js_files to generate compressed css, js file. It will updates html file with respective compressed css, js files. Link, script tags will be loaded with compressed css, js files.

9. If you use django storages, then add the following variable to settings file to load compressed css, js files from s3.

   # AWS details

   AWS_ACCESS_KEY_ID = “Your AWS Access Key”

   AWS_SECRET_ACCESS_KEY = “Your AWS Secret Key”

   AWS_BUCKET_NAME = “Your AWS Bucket Name”

   ENABLE_DJANGO_WEBPACK_AWS = True
