workers-playground

0.4.4

Patch Changes

• Updated dependencies [3a746ac]:
  • @cloudflare/workers-editor-shared@0.1.2

0.4.3

Patch Changes

• #13105 ff41b07 Thanks @petebacondarwin! - fix: resolve TypeError: createRenderer is not a function when built with Vite 8

  Vite 8 switched its bundler from Rollup to rolldown. The @cloudflare/style-provider package ships a hybrid ESM+CJS build (its es/ directory uses require() internally), which rolldown mishandles by generating an anonymous, unreachable module initializer — leaving createRenderer as undefined at runtime.

  Fixed by aliasing @cloudflare/style-provider to its CJS entry (lib/index.js) in vite.config.ts. Rolldown handles plain CJS correctly via its interop layer.

0.4.2

Patch Changes

• #11899 9a1cf29 Thanks @hoodmane! - Remove cf-requirements support for Python workers. It hasn't worked with the runtime for a while now.

0.4.1

Patch Changes

• #12655 a31ee0b Thanks @petebacondarwin! - Migrate workers-playground from Cloudflare Pages to Cloudflare Workers

  Replace the Cloudflare Pages deployment with a Workers + static assets deployment.

  In production (wrangler.jsonc), this is an assets-only Worker with no code entry point — the playground-preview-worker handles all routing and proxying in front of it.

  For local development, a separate config (wrangler.dev.jsonc) adds a Worker entry point (src/worker.ts) that replicates the proxying behavior of the production playground-preview-worker. It proxies /playground/api/* requests to the testing playground-preview-worker, and for the /playground route it fetches an auth cookie from the testing endpoint, transforms it for local use (stripping SameSite/Secure directives and replacing the testing origin with localhost), and injects it into the response so the preview iframe can authenticate.

  The playground-preview-worker referer allowlist is updated to also accept requests from *.workers-playground.workers.dev (in addition to the existing *.workers-playground.pages.dev).

0.4.0

Minor Changes

• #12771 b8c33f5 Thanks @penalosa! - Remove prewarm, inspector_websocket, and exchange proxy from preview flow

  The preview session exchange endpoint (/exchange) has been removed from the edge-preview-authenticated-proxy — it has been unused since the dash started fetching the exchange URL directly (DEVX-979). The prewarm parameter is no longer required or accepted by the .update-preview-token endpoint.

  The playground preview worker now treats exchange_url as optional, falling back to the initial token from the edge-preview API when exchange is unavailable. Inspector websocket proxying and prewarm have been removed in favour of using tail_url for live logs.

Patch Changes

• #12823 784c5cb Thanks @petebacondarwin! - The workers playground's VSCodeEditor's postMessage targetOrigin is updated from '\*' to the specific quickEditHost.

  This prevents the workers-playground from accidentally posting to an incorrect iframe.

0.3.0

Minor Changes

• #12549 10e2e15 Thanks @penalosa! - Add expandable object logging and improved console UI

  The Quick Editor console now displays logged objects and arrays as expandable tree views instead of [object Object].
