1. Progressive Web
Apps
Progressive Web Apps in short PWA.
It’s a way to build applications for all devices with a single codebase.
Using languages we use to create Website.
Progressive Web Apps (PWA), a new and incredibly promising
technology, emerged to irreversibly change the way people interact with
websites.
They are special web applications that are accessed like normal
websites but offer benefits like offline usability, push notifications, and
access to device hardware – things that were previously only available
to native apps.
5. Key Features of
PWAs
1. Offline
Availability
PWAs can be accessed
and used even when the
user is offline,
providing a seamless
experience.
2.Responsive Design
• PWAs are designed to
work on any device,
from desktop
computers to
smartphones, adapting
to the user's screen size
and orientation.
3.Push Notifications
• PWAs can send push
notifications to users,
keeping them informed
about updates and new
content.
6. Benefits of
PWAs
1. Improved User Experience
PWAs offer a fast, reliable, and engaging user
experience, similar to that of a native mobile app.
2. Increased Engagement
PWAs can be added to a user's home screen, making
them easily accessible and increasing engagement.
3.Cost-Effective Development
PWAs can be developed using web technologies,
reducing the need for separate native app
development.
4. Cross-Platform Compatibility
PWAs work across different devices and platforms,
ensuring a consistent user experience.
8. Front-end web development
• It is known as client-side web development.
• It is a procedure of designing the website’s user interface with front-
end technologies like HTML, CSS, and JavaScript.
• HTML (Markup Language)
• CSS (Styling Language)
• JavaScript (Programming Language)
9. HTML
•Web designers use HTML to design the structure and layout of the
website
•Design highly interactive pages
•Most of the static pages are designed using HTML
CSS
•The web designer uses a cascading style sheet that will enhance the website layout
and presentation
•CSS helps to design a webpage using HTML
code
•CSS is widely used by designers and developers to style a
website
Java Script
• To make your website interactive, for example, when searching a query on
Google or clicking on a button to change the page, a JavaScript is working
behind
10. Backend Development:
• Server-side languages: Such as Python, Ruby, PHP, Java, and Node.js handle the
logic and database interactions of web applications.
• Databases: Store and manage data, often using relational databases (like MySQL,
PostgreSQL) or NoSQL databases (like MongoDB, Redis).
Cloud Development:
• Cloud development involves building applications and services specifically for cloud
platforms like AWS (Amazon Web Services), Azure (Microsoft), Google Cloud
Platform, etc.
Cloud Computing Models:
• Infrastructure as a Service (IaaS): Provides virtualized computing resources over
the internet
11. Amazon Web Services (AWS)
Microsoft Azure
Google Cloud Platform (GCP)
• Platform as a Service (PaaS): Provides a platform allowing customers to
develop, run, and manage applications without dealing with
infrastructure (e.g., AWS Elastic Beanstalk, Azure App Service.
Heroku: Cloud platform as a service supporting several
programming languages.
• Software as a Service (SaaS): Delivers software applications over the
internet on a subscription basis (e.g., Google Workspace,
Salesforce).
12. Key Front-end Technologies
• HTML, CSS, JavaScript
These are the core technologies used to build web page structure, presentation, and
interactivity.
• Responsive Frameworks
Libraries like Bootstrap and Foundation help create mobile-friendly and adaptable user
interfaces.
• Single Page Application (SPA) Frameworks
Frameworks like React, Angular, and Vue.js enable the development of dynamic and
efficient web applications
• Testing Tools
Front-end developers use tools like Jest, Selenium, and Cypress to ensure the quality and
reliability of their code.
13. Key Back-end Technologies
Server-side Languages
Popular options include Python, Ruby, Java, PHP, and Node.js.
Database Systems
Relational databases like MySQL, PostgreSQL, and NoSQL databases like MongoDB
and Cassandra.
API Development
Back-end developers build and integrate APIs to enable communication between systems.
Cloud Platforms
Platforms like AWS, Google Cloud, and Microsoft Azure provide scalable infrastructure for back-
end development.
14. The Collaboration between Front and Back-end
1.Design Handoff
• Front-end developers receive design assets and specifications from the
UI/UX team.
2. API Integration
• Front-end developers integrate with the back-end APIs to fetch and
display data.
• API stands for Application Programming Interface
3. Feedback Loop
• Both teams collaborate to identify and address issues, ensuring a cohesive
user experience
15. Career Opportunities in Front and Back-end Development
Front-end Developer
Focuses on the user interface and experience. Uses HTML,
CSS, JavaScript, and UI frameworks
Back-end Developer
Specializes in server-side logic and data management. Utilizes server-
side languages, databases, and APIs.
Full-stack Developer
Proficient in both front-end and back-end development. Can handle
the entire web application lifecycle.
16. Application Development Tools
• Application development tools are the software and platforms that
enable programmers to efficiently create, test, and deploy
applications.
• These tools span the entire software development lifecycle, from integrated
development environments to version control systems and deployment
platforms.
Integrated Development Environments (IDEs)
Visual Studio - A powerful IDE by Microsoft for building Windows, web, and mobile
applications. IntelliJ IDEA- A popular IDE for Java development with advanced code editing and
refactoring capabilities.
Xcode-Apple's IDE for building iOS, macOS, and other Apple platform applications
17. Debugging and Testing Tools
Debuggers: Tools that allow developers to step through code, inspect
variables, and identify and fix bugs.
Unit Testing Frameworks: JUnit, Mocha, and pytest enable automated testing
of individual code components.
Performance Profilers:
Tools that help optimize application performance by identifying bottlenecks
and resource-intensive areas.
18. Frameworks and Libraries
React: A JavaScript library for building user interfaces, maintained by Facebook.
It emphasizes reusable components.
Angular: A platform and framework for building single-page client applications
using HTML and TypeScript, maintained by Google.
Vue.js: A progressive JavaScript framework for building user interfaces, known for
its simplicity and flexibility.
Version Control Systems
•Git:It is a distributed version control system (DVCS) designed to handle
everything from small to very large projects with speed and efficiency. It allows
developers to track changes in their codebase over time, revert to previous versions
of their work, and collaborate seamlessly with others..
•GitHub/GitLab/Bitbucket: Platforms that provide Git repository
hosting, collaboration tools, and CI/CD pipelines.
