Bumps esbuild to 0.28.1 and updates ancestor dependency wrangler. These dependencies need to be updated together.

Updates esbuild from 0.27.3 to 0.28.1

Sourced from esbuild's releases.

v0.28.1

• Disallow \ in local development server HTTP requests (GHSA-g7r4-m6w7-qqqr)

  This release fixes a security issue where HTTP requests to esbuild's local development server could traverse outside of the serve directory on Windows using a \ backslash character. It happened due to the use of Go's path.Clean() function, which only handles Unix-style / characters. HTTP requests with paths containing \ are no longer allowed.

  Thanks to @​dellalibera for reporting this issue.

• Add integrity checks to the Deno API (GHSA-gv7w-rqvm-qjhr)

  The previous release of esbuild added integrity checks to esbuild's npm install script. This release also adds integrity checks to esbuild's Deno install script. Now esbuild's Deno API will also fail with an error if the downloaded esbuild binary contains something other than the expected content.

  Note that esbuild's Deno API installs from registry.npmjs.org by default, but allows the NPM_CONFIG_REGISTRY environment variable to override this with a custom package registry. This change means that the esbuild executable served by NPM_CONFIG_REGISTRY must now match the expected content.

  Thanks to @​sondt99 for reporting this issue.

• Avoid inlining using and await using declarations (#4482)

  Previously esbuild's minifier sometimes incorrectly inlined using and await using declarations into subsequent uses of that declaration, which then fails to dispose of the resource correctly. This bug happened because inlining was done for let and const declarations by avoiding doing it for var declarations, which no longer worked when more declaration types were added. Here's an example:

  // Original code
  {
    using x = new Resource()
    x.activate()
  }
  // Old output (with --minify)
  new Resource().activate();
  // New output (with --minify)
  {using e=new Resource;e.activate()}

• Fix module evaluation when an error is thrown (#4461, #4467)

  If an error is thrown during module evaluation, esbuild previously didn't preserve the state of the module for subsequent module references. This was observable if import() or require() is used to import a module multiple times. The thrown error is supposed to be thrown by every call to import() or require(), not just the first. With this release, esbuild will now throw the same error every time you call import() or require() on a module that throws during its evaluation.

• Fix some edge cases around the new operator (#4477)

  Previously esbuild incorrectly printed certain edge cases involving complex expressions inside the target of a new expression (specifically an optional chain and/or a tagged template literal). The generated code for the new target was not correctly wrapped with parentheses, and either contained a syntax error or had different semantics. These edge cases have been fixed so that they now correctly wrap the new target in parentheses. Here is an example of some affected code:

  // Original code
  new (foo()`bar`)()
  new (foo()?.bar)()
  // Old output
  new foo()bar();
  new (foo())?.bar();

Minor Changes

• #14471 f03b108 Thanks @​DiogoSantoss! - Apply Email Routing addresses during Worker trigger deployment

  Worker trigger deployment now reconciles the Worker's Email Routing rules with the top-level addresses config. This runs for wrangler deploy, wrangler triggers deploy, and clients of @cloudflare/deploy-helpers. After the Worker uploads, or when wrangler triggers deploy runs after a version promotion, the deploy helper asks the Email Routing API for a plan, renders the changes grouped by zone (+ added, ~ updated, - deleted, ! conflict), prompts once for destructive changes in interactive mode, and applies accepted changes through the per-zone rule endpoints. Purely additive plans apply without a prompt, while non-interactive destructive plans fail without modifying rules.

• #14679 deae171 Thanks @​dario-piotrowicz! - Add exclude_packages option to dependencies_instrumentation configuration

  The dependencies_instrumentation config object now accepts an optional exclude_packages field — an array of package name patterns (with glob-style * wildcards) to exclude from the dependency metadata collected during deploy and version uploads.

  // wrangler.json
  {
    "dependencies_instrumentation": {
      "exclude_packages": ["@internal/*", "secret-tool"]
    }
  }

• #14721 4e92e32 Thanks @​dmmulroy! - Support Artifacts sources when creating Queue event subscriptions

  wrangler queues subscription create now accepts the artifacts and artifacts.repo source types supported by the Cloudflare API.

• #13352 d1d6945 Thanks @​penalosa! - Expand automatic resource provisioning to Queue, Dispatch Namespace, and Flagship bindings

  Deployments can now omit the resource name or ID for these bindings. Wrangler will inherit the existing binding on subsequent deploys, create a deterministically named resource automatically, or offer existing resources during an interactive deploy with automatic creation disabled.

• #14688 a0c8bb1 Thanks @​NuroDev! - Print Local Explorer API details for headless agent-driven wrangler dev sessions

  When wrangler dev is started in a headless AI agent environment, Wrangler now prints the Local Explorer API URL and basic resource routes so agents can inspect local Workers and bindings without relying on the interactive UI.

• #14724 a50f73a Thanks @​jamesopstad! - Add a settings export to the experimental cloudflare.config.ts config

  Account-level settings (accountId, complianceRegion) now live in a dedicated, named settings export authored via defineSettings, rather than on the Worker config. A cloudflare.config.ts can export at most one settings object; the Worker itself is the default export.

  // cloudflare.config.ts
  import { defineSettings, defineWorker } from "wrangler/experimental-config";
  import * as entrypoint from "./src/index.ts" with { type: "cf-worker" };
  export const settings = defineSettings({
  accountId: "<your-account-id>",
  });
  export default defineWorker({
  name: "my-worker",
  entrypoint,
  compatibilityDate: "2026-05-18",
  });
