Minor Changes

• #14995 59872c4 Thanks @​ThomasRubini! - Add connect trigger for raw sockets

  You can now configure a Worker to receive raw socket connections during wrangler dev, delivered directly to the Worker's connect(socket, env, ctx) handler:

  {
    "connect": [{ "protocol": "tcp", "port": 5432 }]
  }

  Each entry opens a listening socket on 127.0.0.1 (or the given address) that forwards incoming connections straight to the Worker, bypassing the local dev HTTP entry point. This requires the experimental compatibility flag. Only "tcp" is supported at the moment.

  @cloudflare/config also supports declaring this trigger via triggers.connect(...), which lowers to the connect field above:

  import { defineWorker, triggers } from "@cloudflare/config";
  export default defineWorker({
  triggers: [
  triggers.connect({ protocol: "tcp", port: 5432, address: "127.0.0.1" }),
  ],
  });

• #15172 c68f9cb Thanks @​WillTaylorDev! - Add container support to worker previews

  Worker previews now support containers through a new previews.containers configuration block. Container configuration doesn't inherit, so declare containers explicitly in the previews block to enable them for previews. This mirrors how previews.durable_objects works today. Wrangler names each preview container application {worker_name}_{preview_slug}_{class_name}, normalising and shortening the result to what the API accepts. Either change appends a short digest of the composed name, so two names that would otherwise land on one stay distinct. An entry cannot set its own name, because application names are unique to an account and a fixed name would collide between two previews of the same Worker. A Durable Object class is backed by at most one container application, so the validator rejects two entries that share a class_name. Wrangler skips container applications bound to Durable Object classes that another Worker implements through script_name, because the implementing Worker owns its own container application. A binding is not required: a Durable Object declared through migrations or exports and reached only over ctx.exports can still back a container. Every entry must set class_name. A previews.containers entry whose class_name matches no Durable Object class at all is rejected before the preview deployment is created, so a typo fails loudly instead of producing a preview with no container.

  Wrangler creates the container applications on wrangler preview. Deleting a preview tears them down server side, so wrangler preview delete doesn't remove them.

  Container build and deploy progress prints to stdout. wrangler preview --json suppresses wrangler's own output so it doesn't interleave with the payload, and warnings and errors still go to stderr. Docker's build output and the progress spinner write to stdout directly and bypass that suppression, so parse --json from a non interactive shell, where the spinner is skipped, and prefer a prebuilt image over a Dockerfile.

• #15174 649f667 Thanks @​WillTaylorDev! - [private beta]: Create the parent Worker automatically when wrangler preview targets one that doesn't exist yet

  Previews hang off a parent Worker, so running wrangler preview before the Worker had ever been deployed failed with a raw API error naming the Preview endpoint. Wrangler now offers to create an empty parent Worker and then carries on creating the Preview. The parent uses the same workers.dev and Preview URL settings that wrangler deploy would resolve, without applying routes or cron triggers. In non-interactive environments, Wrangler creates the Worker without asking.

• #14735 30c2d47 Thanks @​vaishnav-mk! - Add individual and batch Workflow instance deletion to the runtime and SDK.

  • WorkflowInstance.delete() deletes one instance. Self-deletion stops the current execution.
  • env.MY_WORKFLOW.deleteBatch(instanceIds) deletes up to 100 instances and returns { deleted, errors } per input position.
  • wrangler workflows instances delete <name> [id..] deletes instances remotely or with --local; IDs can also come from a JSON array passed with --filename, with a combined limit of 100.
