Version 9.0.0

Major

• Updated the required Deno version to v2+.
• Updated the Deno standard library dependencies.

  • They are now https://jsr.io/@std packages, instead of the package https://deno.land/std@0.154.0.

    To migrate, in your server import maps (i.e. importMap.server.dev.json and importMap.server.json):

    - "std/": "https://deno.land/std@0.154.0/",
    + "@std/http/": "jsr:/@std/http@^1.0.12/",
    + "@std/media-types/": "jsr:/@std/media-types@^1.1.0/",
    + "@std/path/": "jsr:/@std/path@^1.0.8/",

  • Ruck now serves JavaScript files with the content type text/javascript instead of application/javascript.

• Updated the function serve that creates the Ruck app HTTP server:

  • Migrated from the deprecated Deno standard library function to Deno.serve.

  • The option port is now optional and defaults to 0. Set 0 to listen on any available port (later get the listening port via the resolved HTTP server property addr.port).

  • It now resolves the created Deno HTTP server instance, of type Deno.HttpServer<Deno.NetAddr>.

    To migrate:

      const abortController = new AbortController();
    - const { close } = await serve({
    + const ruckAppHttpServer = await serve({
        clientImportMap,
        port,
        signal: abortController.signal,
      });

    Later, when you need to abort the server and await it closing…

      abortController.abort();
    - await close;
    + await ruckAppHttpServer.finished;

• Migrated from the deprecated Deno standard library function readableStreamFromReader to the new Deno API Deno.FsFile.readable.
• Migrated from the deprecated Deno APIs Deno.FsFile.rid, Deno.resources, and Deno.close to manually calling the modern Deno.FsFile method Symbol.dispose.
• Ruck app pages no longer include an ES Module Shims script in the server side rendered HTML, as now all modern browsers support import maps.
  • Removed the function serve option esModuleShimsSrc.
  • Removed the React component Html prop esModuleShimsScript.
• Use the TypeScript JSDoc tag @import to import types in modules and readme example code.

Patch

• Updated the GitHub Actions CI config:
  • No longer run the workflow on pull request.
  • Enable manual workflow dispatching.
  • Run checks in separate jobs.
  • For the test job on Linux, disable the modern security feature “AppArmor” so the Chromium developer build installed by Astral can be used (see crbug.com/373753919).
  • Removed custom step names.
  • Use Deno v2.
  • Updated actions/checkout to v4.
  • Updated actions/setup-deno to v2.
• Updated the project and readme import maps for the latest React v18.3.1 URLs.
• Configured Deno to not auto-generate a lockfile.
• Fixed formatting issues caused by updating Deno.
• Added in project and readme scripts the CLI deno flag --allow-import, as required by Deno v2.
• Modernized the project find min compatible Deno version script.
• Modernized the project type check script.
• Modernized the test helper function serveProjectFiles.
• Implemented Deno test steps now that denoland/deno#15425 is no longer an issue.
• Migrated from deno-puppeteer to @astral/astral in tests.
