Astro Compatibility Issues with Older Browsers (Pre-Android 8.0)

As web development continues to evolve, ensuring compatibility with older browsers is crucial for a seamless user experience. Astro, a popular framework for building fast and scalable websites, has faced compatibility issues with older browsers, particularly those running on Android 8.0 or earlier. In this article, we will delve into the compatibility issues with older browsers and explore potential solutions to adapt to these cases.

To better understand the compatibility issues, let's take a look at the Astro configuration used in the provided example.

astro 5.7.3
vite 6.3.2

The configuration uses the @vitejs/plugin-legacy plugin to provide polyfills for older browsers. However, this plugin does not include default imported Layouts or other content in the polyfills. This raises a question: how should we adapt to cases like import {xxx} from 'xx'?

The core problem lies in the fact that the @vitejs/plugin-legacy plugin does not include default imported Layouts or other content in the polyfills. This means that when using Astro's SSR mode, the default imported Layouts or other content are not included in the polyfills, leading to compatibility issues with older browsers.

The bug can be described as follows:

  • The @vitejs/plugin-legacy plugin is used to provide polyfills for older browsers.
  • However, the plugin does not include default imported Layouts or other content in the polyfills.
  • This leads to compatibility issues with older browsers when using Astro's SSR mode.

The expected result is to adapt to cases like import {xxx} from 'xx' and ensure compatibility with older browsers. A reference to low version adaptation can be found in the Vue 3.0 + Vite 6 example.

To reproduce the issue, you can create a new Astro project using the following command:

npm create astro@latest

Add Vue to the project by running the following command:

npm install @astrojs/vue
