Minor Changes

• #7532 9e5fafa2b Thanks @ematipico! - The astro/middleware module exports a new utility called trySerializeLocals.

  This utility can be used by adapters to validate their locals before sending it to the Astro middleware.

  This function will throw a runtime error if the value passed is not serializable, so consumers will need to handle that error.

• #7532 9e5fafa2b Thanks @ematipico! - Astro exposes the middleware file path to the integrations in the hook astro:build:ssr

  // myIntegration.js
  import type { AstroIntegration } from 'astro';
  function integration(): AstroIntegration {
    return {
      name: 'fancy-astro-integration',
      hooks: {
        'astro:build:ssr': ({ middlewareEntryPoint }) => {
          if (middlewareEntryPoint) {
            // do some operations
          }
        },
      },
    };
  }
  

  The middlewareEntryPoint is only defined if the user has created an Astro middleware.

• #7432 6e9c29579 Thanks @ematipico! - Adds a new command astro info, useful for sharing debugging information about your current environment when you need help!

  astro info
  

  Output

  Architecture             arm64

  Integrations             None
  

• #7532 9e5fafa2b Thanks @ematipico! - The astro/middleware module exports a new API called createContext.

  This a low-level API that adapters can use to create a context that can be consumed by middleware functions.

• #7532 9e5fafa2b Thanks @ematipico! - Introduced a new build option for SSR, called build.excludeMiddleware.

  // astro.config.mjs
  import { defineConfig } from 'astro/config';
  
  export default defineConfig({
    build: {
      excludeMiddleware: true,
    },
  });
  

  When enabled, the code that belongs to be middleware won't be imported by the final pages/entry points. The user is responsible for importing it and calling it manually.
