If you're planning to build an app that works on different devices and platforms, you might be wondering whether to use Progressive Web Apps (PWAs) or Electron. Both of these technologies allow you to create apps that work on multiple devices, but they do it in different ways. In this blog, we'll break down the differences between PWAs and Electron so you can decide which one is best for your project.
What is a PWA?
A Progressive Web App (PWA) is like a regular website but with extra powers. It can be installed on your device, work offline, send notifications, and load quickly, just like an app you’d download from an app store. However, you access it through a web browser, and it’s built using standard web tools like HTML, CSS, and JavaScript.
Main Features of PWAs:
Works Everywhere: PWAs can be used on any device with a web browser, whether it's a phone, tablet, or computer.
Offline Support: PWAs can keep working even when you're offline, thanks to a technology called Service Workers.
Installable: You can install PWAs on your home screen without needing to go through an app store.
Push Notifications: They can send notifications to your device, similar to native apps.
What is Electron?
Electron is a tool that allows you to create desktop apps using web technologies like HTML, CSS, and JavaScript. It packages your web app into a standalone desktop application that can run on Windows, macOS, and Linux. Some popular apps, like Slack, Visual Studio Code, and Discord, are built using Electron.
Main Features of Electron:
Native Desktop App: Electron lets you build real desktop applications that work like any other program on your computer.
Cross-Platform: With Electron, you can create one app that runs on Windows, macOS, and Linux.
Full Access to Your Computer: Unlike PWAs, Electron apps can access everything on your computer, like files and system settings, which makes them powerful.
Comparing PWA and Electron
1. Where Can You Use Them?
PWA: You can use PWAs on any device with a web browser. This means they work on phones, tablets, laptops, and desktops. You just need to open the browser and visit the website.
Electron: Electron apps are desktop apps, so you need to install them on your computer. They won’t work on phones or tablets unless you create a special version.
2. How Do They Perform?
PWA: Since PWAs run in the browser, their performance depends on the browser and device you’re using. They are generally fast but may not be as powerful as full desktop apps, especially for heavy tasks.
Electron: Electron apps can be more powerful because they run directly on your computer, not just in the browser. However, Electron apps can use a lot of memory and CPU, which might slow down your computer if you have several open at once.
3. Can They Work Offline?
PWA: PWAs can work offline to a certain extent. For example, a news app might let you read previously loaded articles when you’re offline. However, they can’t do everything without an internet connection.
Electron: Electron apps are full desktop apps, so they can work entirely offline. For example, an Electron-based text editor can let you write and save files without any internet connection.
4. Can They Access Your Computer's Features?
PWA: PWAs are somewhat limited in what they can do on your device. They can access some features, like your camera or location, but they can’t do more advanced things like accessing your file system or sending notifications like native desktop apps can.
Electron: Electron apps can access all of your computer’s features, just like any other desktop app. They can read and write files, access system settings, and more, making them very powerful.
5. How Easy Are They to Build and Maintain?
PWA: PWAs are usually easier to build and maintain because they use standard web technologies and run in a browser. You only need one codebase, and updates are simple because they happen automatically over the web.
Electron: Electron apps also use web technologies, but since they’re desktop apps, there are additional things to consider, like packaging the app for different operating systems (Windows, macOS, and Linux) and managing updates. This can make development and maintenance more complex.
6. Who Should Use Them?
PWA: PWAs are a great choice if you need a simple app that works on both mobile devices and desktops, and you don’t need deep access to the device’s features. They’re perfect for apps like news sites, e-commerce stores, or basic productivity tools.
Electron: Electron is a better choice if you need a powerful desktop app that requires access to your computer’s features, like file management, system notifications, or other complex operations. It’s ideal for building apps like development tools, design software, or communication apps.
Examples of Use Cases
When to Choose PWA:
You need a cross-platform app that works on mobile and desktop.
Your app mainly requires internet access, with some offline capabilities.
You want a lightweight app that users can install from their browser without going through an app store.
When to Choose Electron:
You need a desktop app with full access to the computer’s features.
Your app needs to work entirely offline and perform complex tasks, like handling files or interacting with system settings.
You’re building an app that will be used on Windows, macOS, and Linux.
