Updates astro from 5.1.1 to 5.15.7

Release notes

Sourced from astro's releases.

astro@5.15.7

Patch Changes

• #14765 03fb47c Thanks @​florian-lefebvre! - Fixes a case where process.env wouldn't be properly populated during the build

• #14690 ae7197d Thanks @​fredriknorlin! - Fixes a bug where Astro's i18n fallback system with fallbackType: 'rewrite' would not generate fallback files for pages whose filename started with a locale key.

astro@5.15.6

Patch Changes

• #14751 18c55e1 Thanks @​delucis! - Fixes hydration of client components when running the dev server and using a barrel file that re-exports both Astro and UI framework components.

• #14750 35122c2 Thanks @​florian-lefebvre! - Updates the experimental Fonts API to log a warning if families with a conflicting cssVariable are provided

• #14737 74c8852 Thanks @​Arecsu! - Fixes an error when using transition:persist with components that use declarative Shadow DOM. Astro now avoids re-attaching a shadow root if one already exists, preventing "Unable to re-attach to existing ShadowDOM" navigation errors.

• #14750 35122c2 Thanks @​florian-lefebvre! - Updates the experimental Fonts API to allow for more granular configuration of remote font families

  A font family is defined by a combination of properties such as weights and styles (e.g. weights: [500, 600] and styles: ["normal", "bold"]), but you may want to download only certain combinations of these.

  For greater control over which font files are downloaded, you can specify the same font (ie. with the same cssVariable, name, and provider properties) multiple times with different combinations. Astro will merge the results and download only the required files. For example, it is possible to download normal 500 and 600 while downloading only italic 500:

  // astro.config.mjs
  import { defineConfig, fontProviders } from 'astro/config';
  export default defineConfig({
  experimental: {
  fonts: [
  {
  name: 'Roboto',
  cssVariable: '--roboto',
  provider: fontProviders.google(),
  weights: [500, 600],
  styles: ['normal'],
  },
  {
  name: 'Roboto',
  cssVariable: '--roboto',
  provider: fontProviders.google(),
  weights: [500],
  styles: ['italic'],
  },
  ],
  },
  });
