Build Progressive Web Apps: Python Django PWA Masterclass

Set up and activate a Python virtual environment with venv, then install Django, Crispy Forms, and Crispy Bootstrap five to build a Django PWA.

Explore the personal finance tracker app (pfta) overview, highlighting user authentication, a dashboard with income and expense tracking, offline data sync, and a django-based progressive web application backed by mysql.

Activate the virtual environment, create a Django project and app, migrate to set up SQLite, create a superuser, and run the local server to launch your progressive web app foundation.

Configure a Django PWA to use a MySQL database by installing the MySQL client, updating settings, running migrations, and verifying data in the MySQL console.

configure django to manage static and media files by setting static root and media root, adding media URL in urls, and using collectstatic in development, with debug true versus false.

Register Django admin for income, expense, and category models by defining admin classes with list_display and search_fields. Restart the server to verify the models appear in the admin dashboard.

We aggregate monthly incomes and expenses, convert amounts to float, ensure negative expenses, and combine and sort records by the created at date to render the dashboard.

Create and manage income, expense, and category views in a Django PWA masterclass, using login protection, form handling, commit false saves, and json responses.

Explain the update record view that requires login, handling post requests to update income or expense records by ID, validating the form, saving changes, and redirecting to the dashboard.

Create and organize Django templates by adding a templates directory under your app, with base.html, semantics, and general folders. Test by visiting localhost 9000 to verify the dashboard renders.

Learn to integrate bootstrap into a Django progressive web app by using a static directory, CDN options, and a base html skeleton with key meta tags.

Learn how to integrate bootstrap via cdns for a django pwa template, linking font awesome, google fonts (poppins), bootstrap css/js, and jquery, with proper body and block content structure.

Create a general style sheet for all html pages, then build and style the header, footer, and index, including a dark theme with a Poppins font and custom scrollbars.

Check user authentication to display the dashboard icon and logout button in the header, then build and style the header with url-linked dashboard and logout anchors, load static, and icons.

Build and style the index page by extending the base template, structuring header, content, and footer, and integrating a signup and login flow with a centered logo and forms.

Set the index page background to black, center content with a 90vh flex layout, style 80% wide sign-up/login forms and circular image, with hover and show/hide states for two columns.

Implement client-side logic on the index.html page by creating index.js (using jQuery and vanilla JavaScript) to toggle the eye-icon password visibility and manage sign up and login forms.

wire sign up and login buttons with click event listeners, prevent default, toggle active and inactive forms, and retrieve a csrf token from cookies for secure submissions.

Implement client-side logic with JavaScript to handle sign up and login forms via ajax post, sending data with a csrf token header and redirecting to the dashboard on success.

Build the dashboard page by inheriting from base html and integrating apex charts. Create a series of modals, starting with the income form modal, with header, body, and footer.

Learn to implement modal forms in the Django PWA dashboard by duplicating the income model to expense and category, and building an update modal with a dedicated update form.

Build a dashboard layout with header and footer, a four-column content grid, and card components showing current balance, total income, and total expenses, including last update information.

Create a dashboard layout with row two cards featuring a data chart and income and expense indicators, followed by a responsive Bootstrap table for transactions.

Build the dashboard table body by looping sorted records and rendering rows with category, amount, name, description, and dates. Add update buttons linked to the update modal for each record.

Navigate building dashboard content column two, display the first three incomes with a see more option, then mirror the same for expenses using modals.

Develop the dashboard's JavaScript to manage modals and forms (income, expense, category), ensure scripts run after load, and fix page shift by zeroing body margins.

Implement dynamic dashboard data display and robust form handling for income, expense, and category submissions with event listeners and post data.

Implement dynamic data removal and update on dashboards by adding see more interactions for income, expense, and category, and enabling ajax-based deletions.

Convert a Django app into a progressive web app by configuring a web manifest with name, description, theme color, display, scope, start URL, icons, splash, locale, and service worker.

Configure a web app manifest for the PWA, detailing name, description, theme color, background color, display modes, scope, orientation, start URL, icons, splash screen, direction, language, and service worker path.

Build a service worker for a progressive web app by creating a service worker file in the root directory, defining static and cdn caches, and handling install and activate events.

Post offline data to the backend using form data and headers, log errors, then clear the offline store via a read/write transaction after a successful sync with the service worker.

Modify the dashboard script to track online and offline states, trigger background sync for offline data, and refresh the page when the service worker reports completion.

Explore offline functionality and data syncing for income and expense submissions in a Django pwa, with csrf token handling and posting to create endpoints.

Explore cross-browser and cross-device testing of progressive web apps by debugging service worker tasks - install, activate, fetch, and offline data sync across Chrome, Edge, and Firefox.

Explore performance monitoring for progressive web apps with Lighthouse, analyzing desktop and mobile tests, and applying SEO and accessibility improvements such as alt attributes and meta descriptions.

Master environment-based security for a Django PWA using Python Decouple, an env file, and settings.py to manage secret keys, debug, allowed hosts, and database credentials.

Secure and configure MySQL, set root password, remove anonymous users, disable remote login, remove test database, create ghost user, grant privileges, migrate data, create super user, and collect static files.

Configure apache for a Django pwa by defining a virtual host, server name, document root, static and media aliases, and WSGI settings, then enable https with certbot and test.
