cloudflare/workers-sdk wrangler@4.44.0

on GitHub

Minor Changes

• #10939 d4b4c90 Thanks @danielrs! - Config preview_urls defaults to workers_dev value.

  Originally, we were defaulting config.preview_urls to true, but we
  were accidentally enabling Preview URLs for users that only had
  config.workers_dev=false.

  Then, we set the default value of config.preview_urls to false, but we
  were accidentally disabling Preview URLs for users that only had
  config.workers_dev=true.

  Rather than defaulting config.preview_urls to true or false, we
  default to the resolved value of config.workers_dev. Should result in a
  clearer user experience.

• #11027 1a2bbf8 Thanks @jamesopstad! - Statically replace the value of process.env.NODE_ENV with development for development builds and production for production builds if it is not set. Else, use the given value. This ensures that libraries, such as React, that branch code based on process.env.NODE_ENV can be properly tree shaken.

• #9705 0ee1a68 Thanks @hiendv! - Add params type to Workflow type generation. E.g.

  interface Env {
  	MY_WORKFLOW: Workflow<
  		Parameters<import("./src/index").MyWorkflow["run"]>[0]["payload"]
  	>;
  }

• #10867 dd5f769 Thanks @austin-mc! - Add media binding support

Patch Changes

• #11018 5124818 Thanks @dario-piotrowicz! - Improve potential errors thrown by startRemoteProxySession by including more information

• #11019 6643bd4 Thanks @dario-piotrowicz! - Fix observability.logs.persist being flagged as an unexpected field during the wrangler config file validation

• #10768 8211bc9 Thanks @dario-piotrowicz! - Update logs handling to use the new handleStructuredLogs miniflare option

• #10997 3bb034f Thanks @nikitassharma! - When either WRANGLER_OUTPUT_FILE_PATH or WRANGLER_OUTPUT_FILE_DIRECTORY are set
  in the environment, then command failures will append a line to the output file
  encoding the error code and message, if present.

• #10986 43503c7 Thanks @emily-shen! - fix: cleanup any running containers again on wrangler dev exit

• #11000 a6de9db Thanks @jonboulle! - always load container image into local store during build

  BuildKit supports different build drivers. When using the more modern docker-container driver (which is now the default on some systems, e.g. a standard Docker installation on Fedora Linux), it will not automatically load the built image into the local image store. Since wrangler expects the image to be there (e.g. when calling getImageRepoTags), it will thus fail, e.g.:

  ⎔ Preparing container image(s)...
  [+] Building 0.3s (8/8) FINISHED                                                                                                                                                                                                     docker-container:default
  
  [...]
  
  WARNING: No output specified with docker-container driver. Build result will only remain in the build cache. To push result image into registry use --push or to load image into docker use --load
  
  ✘ [ERROR] failed inspecting image locally: Error response from daemon: failed to find image cloudflare-dev/sandbox:f86e40e4: docker.io/cloudflare-dev/sandbox:f86e40e4: No such image
  
  

  Explicitly setting the --load flag (equivalent to -o type=docker) during the build fixes this and should make the build a bit more portable without requiring users to change their default build driver configuration.
