What are Progressive Web Apps (PWAs)?

Progressive Web Apps (PWAs) are web applications that use modern web capabilities to deliver an app-like experience to users. They combine the best of web and mobile apps, offering fast, reliable, and engaging user experiences. PWAs can work offline, send push notifications, and be installed on a user’s home screen, making them a powerful tool for businesses and developers.

History Of Progressive Web Apps

The concept of Progressive Web Apps was introduced by Google in 2015. The idea was to create web applications that could rival the performance and user experience of native mobile apps. Since then, PWAs have evolved significantly, with major companies like Twitter, Pinterest, and Alibaba adopting this technology to improve user engagement and performance.

Reasons to Choose Progressive Web Apps

Choosing PWAs can be beneficial for several reasons:

• Performance: PWAs are fast and reliable, even on slow networks.
• Cost-Effective: Developing a single PWA can replace the need for separate iOS and Android apps.
• SEO Benefits: PWAs are indexable by search engines, improving visibility.
• User Engagement: Features like push notifications and offline access enhance user engagement.
• Cross-Platform: PWAs work across different devices and operating systems.

Available Frameworks for building PWAs

Several frameworks can be used to build Progressive Web Apps, each with its strengths and weaknesses. Here are some of the most popular ones:

Angular: Offers a robust structure and powerful CLI for building PWAs. It comes with built-in support for service workers, making it easier to create offline-first applications. Angular’s extensive ecosystem and strong community support make it a solid choice for building complex PWAs.

React: Known for its flexibility and extensive ecosystem, React can be used with libraries like Workbox to create PWAs. React’s component-based architecture allows for reusable and maintainable code, and its virtual DOM ensures high performance. It is ideal for scalable applications due to its efficient state management.

Vue.js: Lightweight and easy to integrate, Vue.js is suitable for building small to medium-sized PWAs. Vue’s progressive framework allows developers to start with simple features and gradually scale up as needed. Vue also has official support for service workers through the Vue CLI PWA plugin.

Polymer: Developed by Google, Polymer provides reusable components for building PWAs. It focuses on leveraging web components and is designed to be highly performant and easy to use. Polymer also includes tools for building and deploying PWAs, making the development process smoother.

Ionic: Primarily a mobile app framework, Ionic has strong PWA capabilities, especially when used with Angular. Ionic allows developers to build cross-platform applications with a native-like experience using web technologies. It includes a set of UI components that work seamlessly across different devices.

Available Tech Stacks for building PWAs

Several tech stacks can be used for building Progressive Web Apps, each offering a combination of front-end and back-end technologies. Here are some popular ones:

MEAN Stack: Consists of MongoDB, Express.js, Angular, and Node.js. This stack is ideal for building dynamic web applications with a single codebase for both the client and server sides. Angular’s built-in PWA support makes it a strong choice for PWA development.

MEVN Stack: Consists of MongoDB, Express.js, Vue.js, and Node.js. This stack combines the lightweight and progressive features of Vue.js with the powerful back-end capabilities of Node.js. Vue’s official PWA plugin simplifies the development of PWAs.

MERN Stack: Consists of MongoDB, Express.js, React, and Node.js. This stack is similar to the MEAN stack but with React instead of Angular, MERN is popular for its flexibility and performance. React’s ecosystem includes tools like Workbox for PWA functionalities.

PERN Stack: Consists of PostgreSQL, Express.js, React, and Node.js. This stack is similar to MERN but uses PostgreSQL as the database, offering advanced features like complex queries and transactions. React’s extensive library support makes it suitable for building high-performance PWAs.

LEMP Stack: Consists of Linux, Nginx, MySQL/MariaDB, and PHP. While not traditionally associated with PWA development, LEMP can be used with front-end frameworks like Vue.js or React to build PWAs. Nginx’s performance optimizations can enhance the delivery of PWA assets.

Comparison of PWA Tech Stacks

Choosing the right tech stack for PWA depends on the project’s specific requirements. Below is a comparison of some popular tech stacks:

MEAN vs. MERN

Angular provides a structured and opinionated framework, making it easier for teams to follow best practices. Its built-in PWA support and strong community make it a good choice for enterprise-level applications while React offers more flexibility and a larger ecosystem of third-party libraries. It’s ideal for projects that require dynamic and interactive user interfaces.

MEVN vs. LEMP

Vue.js is lightweight and easy to learn, making it suitable for startups and small to medium-sized projects. Its progressive nature allows for incremental adoption of PWA features while LEMP is traditionally used for server-rendered applications, LEMP can still be effective for PWAs when combined with modern front-end frameworks. Nginx can handle high-traffic loads efficiently.

MERN vs. PERN

MERN offers simplicity and speed with MongoDB’s schema-less design and React’s component-based architecture. It’s great for rapid development and prototyping. On the other hand, PERN PostgreSQL’s advanced features make it suitable for applications that require complex queries and robust data integrity. It provides a more powerful database solution for large-scale applications.

Which Tech Stack One Should Choose for PWA?

Selecting the best and most suitable tech stack for developing Progressive Web Apps (PWAs) depends on various factors, such as project requirements, team expertise, scalability, and performance needs. Below is a comprehensive overview of several popular tech stacks, including their pros and cons.

These statistics highlight the significant advantages of PWAs, making them a compelling choice for businesses looking to enhance their online presence and user engagement.

Acquired by International Companies

Top international companies like X formerly Twitter, Pinterest, Alibaba, and many others have successfully implemented PWAs, significantly improving user engagement and performance. They have tested Progressive Web Apps (PWAs) within their user base with impressive results.

Twitter’s Shift to Progressive Web Apps

Twitter, in particular, is often highlighted for its successful Progressive Web App implementation. As more people use Twitter to follow political news and current events, the PWA allows users who don’t have an account to view tweets and trends directly in their mobile browsers. This increases Twitter’s traffic by making content accessible without the need for app downloads and account creation.

Twitter’s release of its Progressive Web App (PWA) demonstrates its benefits by revealing a 75% increase in total tweets sent and a 70% reduction in data usage. This benefits new users a lot but also enhances the experience for existing Twitter users by providing a faster and more efficient way to access the platform.

Pinterest’s Adoption of Progressive Web Apps

Pinterest, like Twitter, decided to adopt a Progressive Web App (PWA) rather than restricting access to its app or maintaining a separate mobile website. Pinterest’s developers found that only one percent of users engaged with the existing web presence, while the remaining 99% were unwilling to download the Pinterest app or open another application on their phones. The choice to make the content available within the browser was clear and immediate.

Addy Osmani, a Google engineer who assists brands in developing and launching their PWAs, reported significant improvements for Pinterest after the switch. The time users spent on the site increased by 40%, and ad click-through rates rose by 50%, translating into higher revenue for the platform.

Previously, Pinterest’s bulky JavaScript caused users to wait 23 seconds or more for the website to load. By reducing the data load from 650KB to 150KB, Pinterest’s new PWA now loads in an average of just 3.9 seconds, providing a much faster and more efficient user experience.
