What Do I Save In Cache To Run Web App In Pwa? Mới Cập Nhật

To make a web app work offline as a Progressive Web App (PWA), you need to save certain resources in the cache. These resources should be the ones that the app needs to load and run, even when the user is offline. Here are some common resources that you can save in the cache:

1. HTML, CSS, and JavaScript files: These files are essential for rendering the app interface and enabling user interaction.

2. Images and media files: These files may be static or dynamically loaded based on user actions. Caching them can help reduce the app’s load time and improve performance.

3. API responses: If your app uses APIs to fetch data, you can cache the responses to ensure that the app can still display data when the user is offline.

4. Font files: If your app uses custom fonts, you can cache them to ensure that the app renders correctly even when the user is offline.

To save these resources in the cache, you can use a service worker. The service worker is a JavaScript file that runs in the background of the app and intercepts network requests. It can then fetch resources from the cache instead of the network, enabling the app to work offline.

Yes, Progressive Web Apps (PWAs) can use local storage to store data locally on a user’s device.

Local storage is a browser feature that allows web applications to store key-value pairs in the user’s browser. This data is stored locally on the user’s device and can be accessed by the web application even when the user is offline.

PWAs can leverage local storage to provide a seamless user experience by caching key assets and data to improve performance and reduce the amount of data that needs to be downloaded from the server. By using local storage, PWAs can provide users with a fast, reliable experience even when the network connection is weak or non-existent.

However, it is important to note that local storage has some limitations, such as storage capacity and security concerns. Developers should ensure that the data stored in local storage is encrypted and that sensitive data is not stored in local storage to prevent security breaches.

Yes and no.

Progressive Web Apps (PWA) are designed to work in low-connectivity environments and have several features that allow them to function even when there is no internet connection available. For example, PWAs can use caching and offline storage to store previously loaded data, which allows them to display content and respond to user interactions even when there is no network connection.

However, it’s important to note that PWAs still require an internet connection to fully function. Certain features, such as real-time data updates, video streaming, and communication with servers, may not work without an internet connection. Additionally, the initial installation and loading of a PWA requires an internet connection.

So, while PWAs can work with limited or no connectivity, they still rely on the internet to function fully.
